The core of J.P. Morgan's repayment risk analysis is a "reserve burn" stress test. It conservatively assumes vulnerable countries are completely shut out of international bond markets. This forces a reliance on existing reserves and other financing, providing a stark measure of their true financial buffers and resilience against market shocks.

The analysis cautions against taking gross foreign exchange reserves at face value. In countries like Argentina, reserves are heavily encumbered. For Bolivia, they consist mostly of gold. For others like Senegal or Gabon, reserves are pooled. These factors mean the headline number overstates the actual, readily available liquidity for debt servicing.
J.P. Morgan believes the Fed's balance sheet runoff can continue until at least Q1 2026, and potentially longer. The financial system's ability to smoothly handle recent funding stress points (like corporate tax day) suggests that reserves are still abundant enough to support a prolonged QT timeline.
While gross Euro area sovereign bond issuance is set for a new record in 2026, this is primarily driven by Germany. Net issuance for the region will remain similar to 2025 levels, as deficits in other countries are flat or declining, mitigating overall supply pressure.
The surge in emerging market sovereign debt isn't uniform. It's heavily influenced by specific situations, such as Mexico issuing massive debt to back its state oil company, Pemex. Additionally, a notable increase in issuance from lower-rated 'Single B' sovereigns indicates renewed market access for riskier credits.
History shows a strong correlation between extreme national debt and societal breakdown. Countries that sustain a debt-to-GDP ratio over 130% for an extended period (e.g., 18 months) tend to tear themselves apart through civil war or revolution, not external attack.
For nations facing acute liquidity stress, such as Maldives with its large 2026 bond maturity, traditional economic analysis is insufficient. The key mitigating factor is the expectation of "extraordinary bilateral support" from allied nations. This geopolitical safety net is crucial for bridging financing gaps where reserves alone would fail.
Contrary to a simple narrative of improved market sentiment, EM sovereign resilience stemmed from unexpectedly strong macro fundamentals. Better-than-forecast current account balances, export performance, FDI, and portfolio inflows were the primary drivers of stability, exceeding even conservative projections from two years prior.
Despite compressed spreads and improved market access, credit markets are not complacent. Pricing for the most vulnerable emerging market sovereigns still implies a significant 17% near-term and 40% five-year probability of default. This is well above historical averages, signaling lingering investor caution and skepticism about long-term stability.
When countries run large, structural government deficits, their policy options become limited. Historically, this state of 'fiscal dominance' leads to the implementation of capital controls and other financial frictions to prevent capital flight and manage the currency, increasing risks for investors.
Unlike the US, emerging markets are constrained by financial markets. If they let their fiscal balance deteriorate, markets punish their currency, triggering a vicious cycle of inflation and higher interest rates. This threat serves as a natural check on government spending, enforcing a level of fiscal responsibility.
