AI Credit Concerns:
Where Are They Showing Up in Korea?
Tracing AI Credit Stress from CoreWeave to Korea Across Five Market Indicators
Three credit research notes published on October 20–21 reached different conclusions about how far the problems surrounding CoreWeave might spread. We examine those assessments alongside SK Securities' capital-expenditure and cash-flow forecasts, moving from CoreWeave through lower-rated borrowers, Big Tech and the wider US credit market to South Korea. Credit risk has been repriced sharply for CoreWeave and some lower-rated borrowers, and high-yield spreads have widened. But we cannot establish how much AI-related issuers contributed to the broader index move. In Korea, domestic factors complicate the credit-market picture. Shares of Korean data-center suppliers have fallen sharply, but an AI-driven spillover into Korean corporate credit has yet to be identified.

AT A GLANCE · What the Data Show
- One epicenter, three interpretations of the credit risk. Hanwha's Park Jun-young sees a CoreWeave-specific problem; Park Se-yeon at the same firm focuses on lower-rated borrowers and private credit; and Hana Securities' CrediVille team sees potential repercussions along the AI value chain. A separate SK Securities report does not assess credit risk but provides useful cash-flow context: its chart suggests negative consensus free cash flow (FCF) for six companies combined in 2026 and 2027 (visually estimated).
- Credit protection became more expensive first for debt-funded infrastructure providers. Oracle's CDS reached a record high, as did those of several Big Tech firms. Yet Big Tech premiums, at an estimated 50–105bp, remained less than a tenth of CoreWeave's (based on chart readings). The US high-yield spread widened from 263bp on August 31 to 333bp on October 20, but neither CoreWeave's nor other AI issuers' contribution to that change has been established. Redemption pressure in private credit predates the CoreWeave episode.
- Consensus forecasts put the six companies' combined CapEx above operating cash generation. Meta recorded negative FCF of $2.1bn in the third quarter, though its January–September total remained positive at $11.0bn. Long-term debt increased by $22.2bn over nine months. If the 2026–27 projections materialize, the companies must fund any shortfall through existing cash or outside financing, including bonds, joint ventures and private credit (our interpretation). The more they rely on outside funding, the more credit-market pricing can affect the pace of investment.
- Korean three-year credit spreads have widened by roughly 13–19bp across ratings. In percentage terms, the increase exceeds 50% for some top-rated bonds but is only about 3% for BBB0, largely because the starting spreads differed (our calculation). Rate hikes and bank funding dynamics overlap with the spread moves, making an AI-specific contribution difficult to isolate. At its October 22 meeting, the Bank of Korea cited concerns about AI-related corporate bond supply as one factor behind rising long-term yields in international markets.
- The clearest Korean price move has been in data-center suppliers' shares. The median return for 13 Korean data-center supply-chain stocks was −21.1% from October 2 to 19, more than five times the −3.9% median for listed common stocks. But this is a thematically selected group: the semiconductor cycle and valuation repricing may also explain the decline, so the effect of credit fears cannot be isolated. When the KOSPI fell another 3.52% on October 22, doubts about AI investment returns, Middle East tensions and semiconductor trading flows overlapped. Over a longer horizon, the credit quality of end customers placing on-site power-generation orders may matter most (deliveries in 2027–28).
After CoreWeave's five-year credit default swap (CDS) premium exceeded 1,100 basis points (bp) in mid-October, investors began asking how far the problem had spread.1 We follow five sets of market data, working outwards from the epicenter and ending in South Korea. CoreWeave's contracted backlog and debt structure were discussed in NO.14.6
Three Credit Assessments, One Cash-Flow Perspective
Three credit-focused reports dated October 20–21 offer differing views of how far CoreWeave's difficulties could reach. A fourth examines the underlying cash-flow picture. The assessments below are attributed to their original authors.
A Problem Specific to CoreWeave
Single issuerIn this view, CoreWeave's model—borrowing heavily to acquire GPUs and data-center capacity, then recovering the investment through rentals—makes it unusually sensitive to interest rates and financing conditions. The argument rests on divergent CDS pricing and differences in investment scale. The chart puts combined 2026 CapEx for neoclouds CoreWeave and Nebius at roughly $60bn, versus about $680bn for four hyperscalers (visually estimated).1
Condition: provided credit-market turmoil does not lead hyperscalers to cut investment.
A Problem for Debt-Funded Customers and Their Lenders
Part of the industryHer assessment is that demand has not changed; the cost of financing has risen for businesses borrowing to build capacity. Spreads have widened most for lower-rated capacity lessees and their capital providers, rather than AA-rated Big Tech firms.4
Watch point: demand is concentrated among a handful of AI laboratories. If they lose financing, cancelled orders could begin to signal a genuine demand slowdown.
Potential Spillovers Across the AI Value Chain
Possible industry-wide impactHana suggests that BB−-rated CoreWeave is likely a major driver of the widening US high-yield spread and that the consequences may not remain confined to speculative-grade issuers. Its report also includes a chart showing a sharp second-half rise in spreads on 30-year US AI corporate bonds, while spreads excluding AI issuers were broadly flat (visually assessed).3
Limit: no stand-alone CoreWeave credit figures were supplied; the claim relies in part on its rating.
The Cash-Flow Backdrop
Cash-flow evidenceSK argues that high penalties for breaching long-term memory supply agreements (LTAs), together with rising GPU rental prices, make this an attractive entry point for memory stocks. Its Bloomberg consensus charts imply combined FCF of roughly −$30bn in 2026 and −$120bn in 2027 for six companies (visual estimates).7
Caution: the chart aggregates six companies and does not identify which account for the deficit.

Why Did CoreWeave Come Under Pressure First?
Credit markets first repriced the risk of a heavily indebted company building data-center capacity.
CoreWeave uses substantial borrowing to secure GPUs and data-center infrastructure upfront, rents that capacity to customers, and aims to recoup its investment over time. Hanwha analyst Park Jun-young argues that the structure leaves the company particularly exposed to higher rates and tighter financing conditions.1 Its five-year CDS premium exceeded 1,100bp in mid-October, while the yield on one of its bonds briefly topped 16% on October 15. Hanwha's Park Se-yeon refers to a bond maturing in October 2031; Reuters cites a 2032 maturity.1, 4, 5 The 16% figure is a secondary-market yield on an already issued bond—not its coupon rate or the average interest rate on all of CoreWeave's debt. But refinancing or raising comparable new debt at that yield would be costly. Reuters said a CDS premium of 1,000bp implied roughly a 63% cumulative probability of default over five years, compared with approximately 30% a year earlier. This is a market-implied, model-dependent estimate that assumes a recovery rate, not a forecast of the company's actual default probability.5 CoreWeave's remaining performance obligations (RPO)—contracted revenue not yet recognized—totaled $103.7bn at the end of June. Only 41% was expected to be recognized as revenue within the following 24 months. Second-quarter net interest expense equaled approximately 25% of revenue (our calculation).8
CoreWeave Above 1,000bp; Big Tech at Roughly 50–105bp Even at Record Highs

The Cost of Credit for Borrowers—and Redemption Pressure on Lenders
Comparable borrowers and their funders face pressure, but redemptions in private credit were already elevated before the CoreWeave episode.
Hanwha analyst Park Se-yeon argues that what has changed is not underlying demand, but the cost of financing for companies borrowing to build infrastructure. Credit spreads have widened most for borrowers and lessees with weaker ratings than AA-rated Big Tech, and for the firms supplying their capital.4 Oracle was downgraded in July to BBB−, the lowest investment-grade rating on S&P's scale. Its five-year CDS premium reached a record 288bp on October 15.4, 5
The funding side has also evolved. Meta's Hyperion project in Louisiana is being built by a joint venture in which a Blue Owl affiliate holds an 80% interest; the venture issued $27.3bn of bonds. In July 2025, Morgan Stanley estimated that private credit would provide around $800bn of the $1.5tn in external funding required for global data-center investment by 2028.4 Private-credit funds were already experiencing redemption pressure. At Blue Owl Technology Income Corp. (OTIC), redemption requests represented 39% of outstanding shares in the third quarter, broadly unchanged from 40.4% in Q1 and 38.1% in Q2. The company said most requests were resubmissions of previously unfilled tenders. Its quarterly repurchase offer remained capped at 5% of outstanding shares for a third consecutive quarter. Blue Owl had offered quarterly tenders of that size in 2025 as well; this was not a newly imposed emergency restriction.4, 9, 10 The announcement came on October 2, before CoreWeave's CDS surge. Rather than a fresh shock caused by CoreWeave, OTIC illustrates a pre-existing liquidity vulnerability worth monitoring as AI credit concerns grow.
On October 13, the IMF identified 14 circular-financing arrangements in the AI industry since 2023, linking approximately $300bn in equity investments and $650bn in debt with $1.4tn in future revenue commitments. It warned that stress at key recipients of investment could lower expected revenues and investment valuations, in turn weakening the value of debt accumulated in those deals.11
Is Big Tech Credit Still Sound? What Six Companies' Cash Flow Reveals
Heavy investment is tightening cash flow, but Big Tech balance sheets differ substantially from CoreWeave's.
The cost of credit protection for Big Tech has risen too, but the absolute premiums remain far below CoreWeave's. Hanwha's Park Jun-young argues that even after the increase, Big Tech CDS prices remain distinct from those of neocloud providers such as CoreWeave. Ample liquidity and strong credit ratings give hyperscalers greater financial flexibility.1 The direction of travel is nevertheless similar. On October 15, CDS premiums for Amazon, Alphabet, Meta and Nvidia were trading at record levels, although they had risen much more slowly than those for Oracle or CoreWeave.5 By August, spreads on Big Tech corporate bonds had already widened by roughly 30bp from the start of the year, against just 2bp for the broader investment-grade market (J.P. Morgan Asset Management, cited by Hanwha).4 The September Federal Reserve minutes recorded a report from the open-market desk that spreads on hyperscaler bonds used to finance AI infrastructure remained wide, reflecting heavy issuance volumes and relatively long maturities. Fed staff noted that, after widening substantially from low levels earlier in the year, those spreads had narrowed slightly between the July and September meetings.12
When Capital Spending Exceeds Operating Cash Flow
A Bloomberg consensus chart reproduced by SK Securities suggests that combined capital expenditure for Google, Amazon, Microsoft, Meta, Oracle and CoreWeave could rise from roughly $380bn in 2025 to $1.12tn in 2027. Aggregate FCF is estimated at approximately −$30bn in 2026 and −$120bn in 2027. These are approximate readings from a published chart, not raw consensus data.7 If those forecasts prove accurate, the companies would need to bridge the aggregate funding gap over those two years by drawing on cash reserves or raising funds externally through bonds, joint ventures, private credit and similar channels (our interpretation). The Hyperion joint-venture bond in ST.02 is one example of such external financing.

Oracle and CoreWeave may account for a substantial share of the negative FCF (our hypothesis). Hanwha's Park Jun-young also presents a chart in which projected 2027 CapEx for four hyperscalers exceeds 2026 levels (visual estimate).1
How Far Has the High-Yield Market Moved?
US high-yield spreads have widened, but we cannot establish what portion is attributable to AI companies.
The ICE BofA US High Yield Index option-adjusted spread (OAS) rose by 70bp, from 263bp on August 31 to 333bp on October 20—the highest level since July (our calculation). Much of that increase occurred in late September: the spread widened 56bp from 268bp on September 22 to 324bp on October 1, before fluctuating in the low-300s. The sharpest widening therefore preceded the October 15 report that CoreWeave's CDS had exceeded 1,000bp.2, 5 Hana Securities' CrediVille team considers BB−-rated CoreWeave a likely major driver of the widening. Its charts also show spreads on 30-year US AI corporate debt climbing sharply in the second half, while a comparable series excluding AI companies remained broadly flat (visually assessed).3 However, the ICE BofA index measures a broad, weighted universe of US speculative-grade bonds. Without knowing whether and at what weight CoreWeave's bonds are included—and how much their individual spreads contributed—its share of the overall move cannot be established. Higher rates may have increased borrowers' funding pressure at the same time that investors were reassessing AI credit risk, but the data available here cannot disentangle the two. iM Securities noted that a high-yield spread remained below its post-2019 median of 356bp; because its index definition was not specified, we do not compare that benchmark directly with the ICE BofA series in this note.16

Sep 1–Oct 22 · key events across five observation points · bars show periods, dots show dates
Where Has the Risk Shown Up in Korea?
Shares of Korean data-center suppliers have fallen sharply, but an AI-specific spillover into domestic corporate credit has not been identified.
Korean Credit: Spreads Up Roughly 13–19bp Across Ratings
Hana Securities' CrediVille team argues that the early warning signs in Korean credit lie not in lower-rated, high-yield bonds (BBB and below), but in short-dated and top-rated paper. Its reasoning is that Korea's 'canaries in the coal mine' had already reacted to two credit events in the first half, and the domestic credit cycle may have peaked ahead of the global one. With issuance and trading concentrated at shorter maturities this year, new stresses may also show up there first. Its table reports year-to-date percentage spread changes of more than 50% for three-year AAA public-sector and bank bonds, about 3% for BBB0, and around −40% for commercial paper (CP).3
Converting the same table into basis-point moves tells a different story. AAA public-sector bonds widened from 22.9bp to 35.6bp, a gain of 12.7bp. The increases for AAA bank bonds, AA− corporates, AA− specialized credit finance companies and BBB0 corporates were 13.2bp, 16.9bp, 19.4bp and 14.4bp respectively (our calculations). Across those ratings, the absolute widening was broadly similar—around 13–19bp. The large variation in percentages reflects the starting point: the top-rated spread began in the low 20s, compared with roughly 500bp for BBB0. A 14bp move is substantial relative to 23bp but small relative to 500bp. Hana's use of proportional changes therefore still offers a valid perspective.
In Basis Points, Top-Rated and BBB Flat Bonds Widened by Similar Amounts
YTD 2026 credit-spread changes · 3Y bonds measured over Korean Treasuries; CP over 3-month Bank of Korea Monetary Stabilization Bonds · latest around Oct 19 (table date not specified)
That does not make Hana's conclusion irrelevant. The firm also notes that Korean lower-rated bond prices are relatively poor indicators of actual market conditions and that their correlation with overseas credit markets is limited.3 A fair reading is that top-rated and shorter-dated instruments, where price discovery is more reliable, may provide earlier signals (our interpretation).
Most of the Rise in Yields Came from Government Bonds
The yield on three-year AAA public-sector bonds rose 105bp from 3.18% at the start of the year to 4.23%. Of that rise, about 93bp came from Korean Treasury yields and 13bp from the credit spread. The 91-day CP yield rose 49bp: three-month Monetary Stabilization Bond yields rose 80bp, while the CP spread narrowed by 31bp (as of October 19).3 Hana attributes the recent rise in short-term rates to a funding premium driven by banks absorbing liquidity from the market. Net issuance of both bank bonds and securities backed by term deposits has increased since August.3 Two Bank of Korea rate hikes in July and August (from 2.50% to 3.00%) coincided with changing bank funding conditions. That overlap makes it difficult to isolate any AI-related contribution to wider Korean spreads.19
Most Yield Increases Came from Sovereign Rates; Short-Term Credit Spreads Actually Narrowed
Breaking down yield changes since the start of 2026 · as of Oct 19
Spreads widened in the most recent week as well. Between October 12 and 16, the 10-year Korean Treasury yield fell 24.7bp, but credit yields did not fall by as much; three-year spreads widened by 0.8–1.7bp across ratings. Hana expects overseas credit developments and other pressures to leave Korean credit spreads broadly weak or wider in the near term.3
On October 22, the Bank of Korea left its policy rate at 3.00%, with all seven Monetary Policy Board members voting in favor. It said it needed to assess the effects of its two earlier hikes before deciding the timing and pace of any further increases. The Bank expects growth this year and next to substantially exceed its August forecasts of 3.3% and 2.9%, with inflation staying above target for some time. The hold should therefore not be read as a dovish turn. In discussing the sharp rise in long-term government bond yields internationally, the Bank cited inflation, expectations of rate increases in major economies, fiscal sustainability concerns and 'concerns about AI-related corporate bond supply.' It did not attribute widening Korean corporate credit spreads to an AI-driven spillover.18 The decision matched market expectations. In a pre-meeting survey, all 10 securities-industry analysts expected a hold; most anticipated further hikes in November and the first quarter of 2027.20 This note does not incorporate the bond-market reaction after the Monetary Policy Board decision, including changes in short-term yields or bank- and public-sector bond spreads.
Equities: The Biggest Moves Were in Supply-Chain Stocks
Among Korean assets, data-center supply-chain shares have moved most conspicuously in the same direction as AI credit concerns. According to Hanwha's Park Se-yeon, eight of 13 selected Korean data-center suppliers lost more than 20% between October 2 and 19. Their median return was −21.1%, over five times the −3.9% median for listed common shares. Memory (−25.8%) and electrical equipment (−22.3%) were hit hardest; only two backup-battery suppliers posted gains.4 However, the 13 stocks were selected by theme, spanning semiconductors, electrical equipment, cooling and on-site power generation. The decline may also reflect the semiconductor cycle and a reassessment of valuations. The Bank of Korea likewise cited concerns about weaker profitability in semiconductors as one factor in the Korean equity selloff.18 As with Korean credit spreads, it is not possible to separate the share-price impact of AI credit concerns from other forces.
Eleven of Thirteen Suppliers Fell; Only Two Backup-Battery Stocks Rose

The benchmark index was volatile too. The KOSPI fell 3.73% to 5,552.74 on October 20, then rose 3.29% to 5,735.66 the next day, recovering 85% of the previous session's point loss.21 AI cloud provider Elice, which listed on October 20, fell 32% below its IPO price on debut despite a retail subscription ratio of 408 to 1. Kiwoom Securities saw this as a possible sign that questions over returns on AI-infrastructure investment—arising in the wake of CoreWeave—were affecting newly listed AI shares, alongside more conventional factors such as an ambitious IPO valuation.22
The KOSPI could not sustain the rebound on October 22. It lost 3.52% to close at 5,533.77, below its October 20 close. Samsung Electronics fell 4.03% and SK hynix 5.49%.17 Aju Business Daily cited several overlapping drivers: doubts about AI investment profitability, including Meta's lack of specific 2027 CapEx guidance and its negative Q3 FCF; geopolitical tensions in the Middle East; profit-taking in semiconductors following the prior day's rebound; and reduced buying support after corporate share-repurchase programs ended.23 Given the mix of factors, the October 22 decline cannot be described as further evidence that CoreWeave's credit problems had spread to Korean equities. To trace a genuine credit channel, we would need to examine spreads on individual Korean corporate bonds and companies' actual financing terms. Figure 7 retains its original October 2–19 comparison because the same stock universe and benchmark group have not been recalculated through October 22.
The Korean won moved the other way. The USD/KRW exchange rate fell to ₩1,328.10 per dollar on October 20, meaning the won strengthened.24 iM Securities economist Park Sang-hyun described this divergence as two markets reading the same economy differently: equities were pricing in doubts about the AI cycle, while foreign exchange was reflecting expectations that the semiconductor boom would continue to support Korea's trade and current-account surpluses.25
The Longer-Term Exposure: Customers' Credit Quality
Beyond share prices, a lasting vulnerability may lie in the buyers placing orders. Park Se-yeon argues that on-site power-generation equipment, with delivery dates extending into 2027–28, faces financing risk for longer than other parts of the Korean supply chain. Even within one supply chain, exposure depends on the credit standing of the ultimate customer.4 On October 6, Doosan Enerbility shipped its first 380MW gas turbine to SpaceXAI, an AI company led by Elon Musk, according to the cited report. Under the five-turbine order from the same US Big Tech customer, three units added in December 2025 are scheduled for delivery—one in 2027 and two in 2028.26, 27 Publicly disclosed contract details, however, are insufficient to determine the credit quality of the entity legally responsible for payment or whether a parent-company guarantee exists.
Demand and Relative Scale Tell a Different Story
Demand Indicators Have Not Broken Down
North American data-center vacancy was 1.4% in the first half of 2026, according to CBRE, and over 80% of the 7,481MW under construction had already been pre-leased. Five major tech companies raised CapEx guidance a total of 15 times between January 2025 and July 2026 (Hanwha's Park Se-yeon, citing CBRE).4
CoreWeave Is Small by Comparison
Projected combined CapEx for neoclouds in 2026 was around $60bn, less than one-tenth of the roughly $680bn projected for four hyperscalers (Hanwha's Park Jun-young; visual chart estimates).1
GPU Rental Prices Are Rising
SK Securities argues that rising GPU rental rates shorten payback periods, while long-term memory supply agreements carry sufficiently high breach costs to discourage easy cancellation.7
These counterarguments speak to demand and relative company size. They do not negate the fact that financing costs have already risen for debt-funded infrastructure providers. Park Se-yeon likewise sees resilient demand indicators, but locates the risk primarily in the creditworthiness of the parties expected to pay for that demand.4

- Hyperscaler
- A large cloud platform operating data centers at enormous scale, such as Amazon, Microsoft or Google. The composition of the 'four Big Tech firms' differs between source reports.
- Private credit
- Direct lending to companies by investment funds and asset managers rather than banks. Fund redemption windows and tender limits can restrict when investors receive cash.
- Free cash flow (FCF)

Hanwha (Park Jun-young), Figure 1 (CDS): Big Tech four-company endpoints around 50–105bp, CoreWeave October peak around 1,125bp, Oracle chart endpoint around 320bp. Figure 3 (2026F CapEx): neoclouds around $60bn and hyperscalers around $680bn. |
| Our calculations | Korean three-year credit spread change (bp) = latest less start-of-year: AAA public-sector 35.6 − 22.9 = +12.7; AAA banks 38.6 − 25.4 = +13.2; AA− corporates 67.7 − 50.8 = +16.9; AA− specialized finance 74.0 − 54.6 = +19.4; BBB0 corporates 511.1 − 496.7 = +14.4; A1 91-day CP 47.0 − 77.9 = −30.9. Reproduced percentage changes: +55.5%, +52.0%, +33.3%, +35.5%, +2.9%, −39.7% (Hana reports +55%, +52%, +33%, +36%, +3%, −40%). US HY: 333 − 263 = +70bp; Sep 22 → Oct 1: 324 − 268 = +56bp; 333bp on Oct 20 was the highest since Jul 1. Meta long-term debt: $80.922bn − $58.744bn = +$22.18bn. Meta FCF: cash from operations $32.786bn − PP&E purchases $33.942bn − finance lease principal $0.964bn = −$2.12bn (matches Meta's reported figure). CoreWeave Q2 net interest expense/revenue: $0.640bn / $2.575bn = 24.9%. The KOSPI regained 182.92 of the 215.27 points lost on Oct 20 (5,735.66 − 5,552.74), or 85%; Oct 20 decline: 215.27 / 5,768.01 = 3.73%. |
| Differences across sources | CoreWeave CDS: Park Jun-young at Hanwha says 'above 1,100bp'; Reuters and Park Se-yeon say 'above 1,000bp'. CoreWeave bond yield: Park Jun-young gives approximately 15–16% (citing news reports); Park Se-yeon reports a yield briefly above 16% on an Oct 2031 bond on Oct 15; Reuters cites a 2032 issue trading around 78 cents on the dollar with a yield just over 16% (Tradeweb). Oracle CDS: Reuters / S&P Global MI gives 288bp on Oct 15; Park Jun-young's text says 'approaching 300bp'; chart endpoint visually reads around 320bp (possibly reflecting a different date). AAA public-sector yield decomposition: 93 + 13 = 106bp versus 105bp for the reported total (rounding). |
| Source verification notes | Hana's CrediVille report gives CoreWeave a BB− rating without naming the rating agency. SK Securities charts aggregate six companies without reporting individual figures. Hanwha's Park Se-yeon names the gas-turbine buyer 'xAI'; this note uses 'SpaceXAI' following Doosan Enerbility shipment coverage dated Oct 6. Figures from Blue Owl, J.P. Morgan Asset Management and Morgan Stanley are cited within Park Se-yeon's report. The four Big Tech names differ by source: Reuters uses Amazon, Alphabet, Meta and Nvidia; Hanwha's chart uses Microsoft, Google, Amazon and Meta. iM Securities' post-2019 high-yield median of 356bp is omitted from Figure 4 because its underlying index is unspecified. ICE BofA index data carry redistribution restrictions on FRED, so only selected observations, not a daily time-series chart, are reproduced here. |
| Estimates and interpretations | Statements that the projected funding gap requires cash reserves or external financing, that top-rated and short-dated Korean bonds may offer earlier signals, and that Meta's results show both investment expansion and diversification of funding options are this note's interpretations. The possibility that Oracle and CoreWeave account for a large share of negative aggregate FCF is our hypothesis. Classifications at the five observation points and judgments in the spillover table are our assessments. Figure 1 is schematic. |
- Hanwha Investment & Securities, Park Jun-young (research associate Kim Na-woo), 'The CoreWeave Episode Does Not Mean the End of AI Investment,' Semiconductor Industry Analysis (Positive), Oct 21, 2026. Page 1: 'CoreWeave's five-year CDS premium exceeded 1,100bp in mid-October'; some bond yields at approximately 15–16% (citing media reports); Oracle CDS approaching 300bp. CoreWeave borrows heavily to secure GPUs and data centers in advance, then seeks to recoup the cost by renting capacity to customers, making it sensitive to rates and financing conditions. Hyperscalers have greater financial flexibility thanks to ample liquidity and high credit ratings. Unless credit-market stress actually leads hyperscalers to cut investment, growth drivers for HBM4 and server DRAM remain intact in 2027. Figure 1: CDS trends for neoclouds and hyperscalers. Figure 2: hyperscaler CapEx, 2026 vs 2027. Figure 3: 2026 CapEx comparison; neoclouds = CoreWeave + Nebius; hyperscalers = Microsoft + Google + Amazon + Meta.

- Hana Securities, Kim Sang-man, 'Not High Yield (HY) but High Sensitivity: Korea's Barometers Are Short-Dated and Top-Rated Bonds,' CrediVille, Oct 21, 2026. Page 1: with CoreWeave rated BB−, it is 'likely a major driver of recent high-yield spread widening'; the effects may not remain limited to speculative-grade issuers. Korean high-yield (BBB or lower) spreads remained firm. The report suggests Korean lower-rated bond pricing indicators are less reflective of actual conditions, while correlations between domestic and foreign credit markets are limited. Korea may already have passed its credit-cycle peak. Short-term rate increases reflect an 'additional premium from supply and demand pressures.' Chart 1: US AI vs non-AI 30-year corporate spreads and HY spreads. Chart 3: year-to-date spread percentage changes (Infomax). Chart 4: AAA public-sector 3Y yields 3.18% → 4.23%, with +93bp from KTB yields and +13bp from the spread. Chart 5: CP 91D yield +49bp = +80bp in 3M MSBs and −31bp in the spread. Chart 7: net bank-bond and term-deposit-backed issuance rose from August. Weekly credit conditions: Oct 12–16, 10Y KTB −24.7bp and 3Y spreads +0.8 to +1.7bp (Chart 2); foreign credit events and other pressures are expected to keep spreads steady to wider. The report saw a low probability of a further BoK hike on Oct 22.
- Hanwha Investment & Securities, Park Se-yeon, 'Permits Stalled Data Centers; Investment Kept Growing,' ESG, Oct 20, 2026. Page 1: eight of 13 Korean data-center suppliers fell more than 20% between Oct 2 and 19; five Big Tech companies raised CapEx guidance 15 times; what changed was financing costs for companies borrowing to build, not demand (CoreWeave bond yield briefly >16% on Oct 15). Page 2: 2,428 listed common stocks traded in all nine sessions had a median return of −3.9%, versus −21.1% for the 13 suppliers; memory −25.8%, electrical equipment −22.3%, cooling −21.1%, on-site generation −18.9%; only the two backup-battery names rose (Samsung SDI +11.9%, LG Energy Solution +16.5%). Figure 6: Quantiwise. North American data-center vacancy: 1.4% in H1 2026, with more than 80% of 7,481MW under construction pre-leased (CBRE). Alphabet, Meta, Amazon, Microsoft and Oracle raised guidance 15 times between Jan 2025 and Jul 2026. Section 4: demand concentrated in a handful of AI labs; Meta Hyperion joint-venture bonds of $27.3bn (Blue Owl affiliate: 80% ownership; Meta 10-Q / IFR); Morgan Stanley's Jul 2025 estimate that private credit would supply about $800bn of the $1.5tn in outside capital through 2028; two Blue Owl private-credit funds offering quarterly tenders capped at 5% for a third consecutive quarter; OTIC requests around 39% of shares. Big Tech bond spreads +30bp YTD vs broader investment grade +2bp (J.P. Morgan Asset Management, August). Oracle downgraded to BBB− on Jul 9 (S&P), with record 5Y CDS 288bp on Oct 15 (S&P Global MI); CoreWeave's Oct 2031 bond yield briefly >16% on Oct 15, CDS >1,000bp, a record. Spreads widened most for lower-rated capacity lessees and their lenders rather than AA-rated Big Tech. On-site generation deliveries in 2027–28; gas turbine buyer identified as xAI. Three issues for Meta earnings: maintenance of the CapEx plan, price versus volume behind any increase (particularly memory), and spending timing. 'The risk lies less in demand than in who is expected to pay.' Figure 9 calendar: Meta Oct 22 KST; SK hynix Oct 28; Samsung, Alphabet, Microsoft Oct 29 (early morning for US releases); Amazon Oct 30 (early morning); Q4 private-credit redemption results expected in early Jan 2027.
- Reuters, Tom Westbrook and Amanda Cooper, 'AI Credit Fears Push Tech Default Insurance to Record Highs,' Oct 15, 2026 (republished by BusinessDay). Amazon, Alphabet, Meta and Nvidia CDS traded at record levels; Oracle five-year CDS at 288bp, up from 260bp one week earlier; SoftBank five-year CDS at 424bp, up 24bp on the day; CoreWeave CDS >1,000bp (S&P and LSEG), debt approximately $50bn (LSEG). A 2032 bond traded near 78 cents on the dollar with a yield just over 16% (Tradeweb). The report estimated that 1,000bp implied a five-year cumulative default probability of about 63%, versus about 30% a year earlier. Big Tech CDS rose much less rapidly than Oracle's or CoreWeave's. businessday.co.za
