US vs China Debt: What Sovereign CDS Spreads Show (2026)

This analysis represents my private view only. It is not investment advice. CDS spreads are market prices, not forecasts.

CDS prices who might default; it doesn’t price who might lead.

This article is written as data storytelling, not market commentary: the datasets drive the narrative, not the other way around. Macroeconomics invites narrative economics — theory first, cherry-picked charts second. Sovereign CDS is a useful antidote. Retail investors watch bond yields, but yields are distorted by central-bank balance sheets (QE/QT, domestic ownership, financial repression). CDS strips much of that noise and asks a narrower question: what does the market charge to insure against default? It is imperfect and sometimes illiquid, but as a storytelling device it surfaces signals that headline fiscal statistics bury.

The chart that frames everything

Sovereign CDS measures default risk; interest/GDP measures what governments actually pay. On a log-scale CDS axis (so Egypt at 306 bps does not crush the US–China cluster), four quadrants emerge. Gray dots are the full sample; highlighted countries tell the story — including US–China CDS parity near 40 bps while interest burdens diverge.

Markets price solvency risk in CDS. Strategists price supremacy in R&D, fabs, and AI capex. CDS prices who might default; it doesn’t price who might lead. The two timelines are diverging — and neither alone tells you who wins the next decade.

1 — The supremacy race, sidelined by debt

Washington and Beijing are competing on semiconductors, artificial intelligence, green technology, and military reach. That contest dominates headlines. Yet the fiscal arithmetic running underneath may prove more binding than any export control list.

The surprise in the data is not that both giants carry heavy balance sheets — it is that CDS prices them as equals. China at 40.6 bps is marginally wider than the United States at 38.2 bps. A decade ago China traded far wider. Compression reflects both improved perceptions and thinner, less informative liquidity in some sovereign CDS contracts — but the parity still matters: the market is not giving the US a free pass on its debt trajectory.

On fundamentals the asymmetry is stark. US net interest is approaching $1 trillion per year — roughly 14–15% of federal outlays and over 20% of federal revenues (CBO).[3] That is real money diverted from defence modernisation, industrial policy, and the very supremacy race policymakers say they are running. China reports lower on-budget interest (~1% of GDP) but local-government financing vehicles and property-sector debt mean the true public balance sheet is larger and less transparent than headline IMF figures suggest.[2]

A fiscal Nash equilibrium

The US–China debt race is best read not as a horse race between two balance sheets, but as a Nash equilibrium in game theory: neither player has an incentive to unilaterally change strategy, even though the joint outcome is suboptimal. Washington cannot cut chip subsidies, defence R&D, or industrial-policy spending without ceding technological ground to Beijing. Beijing cannot rein in LGFV roll-overs, property-sector support, or manufacturing subsidies without risking stagnation and missing the AI frontier. Both are locked into permanent fiscal expansion — and the data reflects it: the US adds more than $1 trillion to its debt stock every several months; China continues channelling credit through state-backed technology and infrastructure channels.

Simplified 2×2 payoff matrix. The top-left cell — high spend on both sides — is the Nash equilibrium: neither bloc can deviate without accepting strategic defeat.

The market is not pricing a conventional “bankruptcy” for either sovereign. At 38–41 bps, 5-year CDS implies roughly 0.4% annualised default risk — remote for reserve-currency and manufacturing-superpower balance sheets. What the compression does price is that both strategies lead to the same destination: unprecedented debt accumulation with shrinking room to manoeuvre. CDS is pricing the trap, not the trigger.

Transparent debt vs structural opacity

One asymmetry the CDS chart cannot fully resolve is balance-sheet visibility. US fiscal data is loud, public, and updated in near real time — CBO projections, Treasury statements, FRED series. China’s on-budget figures look manageable (~99% debt/GDP on IMF definitions); the structural picture is murkier. Local-government financing vehicles, property-sector guarantees, and shadow-banking channels mean the true public footprint may exceed 120% GDP with less granular disclosure.[2]

That contrast is itself a storytelling angle: how does CDS price risk when one player’s balance sheet is audited daily and the other’s is partially hidden? Part of China’s slight CDS premium (40.6 vs 38.2 bps) may reflect opacity and liquidity premia, not a clean verdict on relative solvency. Part of US compression may reflect dollar hegemony and the deepest CDS market. The near-parity is less “they are equally safe” and more “the market sees two giants locked in the same fiscal game, with different accounting conventions.”

My read: The supremacy narrative is forward-looking (who builds the better GPU stack, who allies with whom). The debt narrative is backward-looking arithmetic that compounds. CDS prices who might default at roughly the same rate for both — it does not price who might lead. You cannot run a decades-long great-power competition while interest alone consumes a fifth of US revenues — unless growth outruns it, which is the bet embedded in today’s spreads.

2 — Europe: financially stabilised, structurally unfinished

If the US–China story is about debt crowding out ambition, Europe’s story is the opposite at first glance: financial stabilisation without full structural closure.

The euro crisis nearly tore the currency union apart. In September 2011, Greek 5-year CDS exceeded 7,300 basis points — the market priced near-certain default. Portugal, Ireland, Italy, and Spain were all in triple-digit or quadruple-digit territory. The BIS documented how sovereign stress transmitted into bank funding costs across the bloc.[5]

Today? Greece at 29 bps. Portugal at 17. Spain at 16. Ireland near 13 (indicative). The compression is one of the most dramatic repricings in modern sovereign markets — visible only on a log scale.

But stabilisation in market spreads is not stabilisation in public finances. Greece still carries 146% debt/GDP. Italy 137%. Spain just cleared 100%. Italy spends 3.9% of GDP and 7.6% of government expenditure on interest alone (Istat/Eurostat).[7] The CDS market says “safe enough.” The budget says “still paying for the past.”

Debt service — where interest still hurts

3 — Germany: the solvency anchor in a compressed spread world

Germany at 7.8 bps is the European benchmark — five times tighter than the United States, four times tighter than Italy. The BIS has long noted Germany’s role as the euro-area reference entity in sovereign CDS markets.[4]

Yet Germany is no longer the fiscal ascetic of the 2010s. Debt/GDP has risen to 63.5% with projections toward ~76% by 2028 as defence and special funds accelerate borrowing (Bundesbank/BMF). Interest remains manageable (~1% of GDP) — but the direction is up.

Germany vs peers — CDS today

Germany anchors the bottom; US and China cluster in the developed-middle band despite supremacy rivalry.

Germany’s solvency premium lets the periphery borrow through compressed spreads. That is Europe’s financial miracle — and its hidden dependency. If German spreads widened, the whole compression trade unwinds.

4 — Emerging markets: CDS stress where budgets break

Not all emerging markets are equal. Sovereign CDS separates countries with moderate debt and rising spreads (Indonesia, +22% YoY) from countries where interest already devours the state (Egypt, ~74% of government revenues; Brazil, ~30% of revenues and 8% of GDP).[2]

Red-tinted bars: annual CDS widening >15%. Indonesia is the standout riser despite moderate debt/GDP (~41%).

5 — What matters more: solvency or technological supremacy?

This is the question CDS cannot answer — because it prices default risk on existing debt, not capacity to innovate. To argue the supremacy side with the same rigour as the solvency side, we need different data.

Chart — supremacy proxies (US, China, EU-27, Germany, Japan)

Three imperfect but comparable proxies: R&D intensity (% of GDP), semiconductor fabrication share (global capacity), and large-scale AI compute (estimated %). None is CDS; together they sketch who is investing in the future.

R&D, semiconductors, and AI compute — by bloc

R&D: Eurostat/OECD/UNESCO 2023. Semiconductors: SEMI/industry estimates 2024. AI compute: Epoch/OECD estimates 2024.[8][11][12] Data: sovereign-tech-supremacy.json.

The chart makes the European gap visible: EU-27 matches neither US R&D (~3.5%) nor China’s fabrication build-out (~18% global capacity), and trails sharply on AI compute. Germany’s industrial R&D (~3.1%) is strong by European standards — but its semiconductor and compute shares remain small. CDS prices who might default; these bars hint at who might lead.

What solvency buys you

Fiscal space. The ability to fund defence, subsidies, and crisis response without a market strike. Japan carries 236% debt/GDP but benefits from domestic ownership and low rates — until CDS starts repricing (+28% YoY in our sample). Egypt shows the opposite: 306 bps CDS and interest consuming three-quarters of revenues — supremacy in any form is off the table.

What technological supremacy buys you

Growth optionality. The US CHIPS Act, hyperscaler AI capex, and dollar weaponisation are bets that productivity and strategic assets outrun debt service. China’s EV and battery supply chains are the mirror bet. Both powers are borrowing to finance the race and paying for past borrowing simultaneously.

Where the equilibrium breaks

Elite data storytelling does not stop at describing the trap — it sketches the breaking points. If the Nash equilibrium forces interest payments to consume an ever-larger share of revenues, three endgames dominate the policy debate (none mutually exclusive):

• Managed inflation / financial repression. Nominal growth runs above borrowing costs; debt ratios stabilise through erosion of real liabilities. Japan is the template; the US and China are larger and more globally coupled — the externalities differ.
• Currency and reserve-status adjustment. For the US, sustained debasement risks the dollar’s exorbitant privilege; for China, capital controls and yuan internationalisation set limits. CDS stays compressed until a regime shift reprices convertibility or governance risk.
• Structural growth downshift. If neither productivity miracles nor inflation bailouts arrive, interest crowds out investment — the supremacy race stalls because the fiscal race accelerated. That is the scenario CDS underprices today: not sudden default, but chronic underperformance.

The constraint that binds first differs by bloc. For the US, it may be interest as a share of federal revenues (already above 20%). For China, it may be credit misallocation and property-sector drag surfacing through LGFV stress — visible in spreads before it is visible in headline GDP. For Europe, it may be technological gap while CDS still prices “safe enough.” The right question is not abstract solvency vs supremacy, but which margin cracks first in each system.

Europe’s uncomfortable middle

Europe may be winning on the solvency scorecard relative to 2011 — spreads healed, no periphery blow-up imminent. The supremacy chart above shows why the middle is uncomfortable: EU-27 R&D at 2.2% vs US 3.5%, semiconductor share stuck near 9% against a Chips Act target of 20% by 2030,[9] and AI compute share in the low single digits. No EU company sits among the world’s top ten by market capitalisation (2025) — platform power, not industrial depth.

Ireland is the exception in our sample: 33% debt/GDP, ~13 bps CDS (indicative), and a tech-FDI hub hosting US hyperscaler infrastructure. Solvency and tech footprint can coexist — but it is not the euro-area median.

Solvency keeps you in the game. Technological supremacy determines what game you are playing in 2035. Europe improved the first; the US and China are betting everything on the second — while both undermine the first with debt. CDS prices who might default; it doesn’t price who might lead. The optimal strategy is both; the fiscal math allows neither bloc a free lunch.

For policymakers the implication is uncomfortable. Compressed European CDS spreads reward fiscal consolidation narratives — but may underprice the cost of falling behind on chips, AI, and defence tech. Elevated US–China CDS parity rewards the view that debt trajectories are manageable — until they are not. Markets are pricing near-term default risk. Citizens should also price long-term strategic capacity.

Bottom line

The US and China are locked in a fiscal Nash equilibrium — high spend on both sides, compressed CDS near 40 bps, mutual loss of flexibility — while both accumulate debt at historic scale. Europe has achieved a remarkable financial stabilisation since 2011, but high debt stocks and heavy interest lines persist, while technological competitiveness lags the two superpowers. Emerging markets split between manageable spreads and fiscal crises driven by debt service, not headline GDP.

CDS prices who might default; it doesn’t price who might lead. It prices the trap: two superpowers that cannot blink without losing the supremacy race, borrowing to stay in the game while interest arithmetic compounds. Solvency keeps the lights on. Technological supremacy decides who owns the future. The data says we are underpricing the tension between them — and the endgames when the equilibrium stops holding — in Washington, in Beijing, and in Brussels.
