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.

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.

Despite a constructive view on commodity currencies like the Chilean peso and South African rand, their respective central banks have recently announced reserve accumulation programs. This intervention acts as a direct headwind, making the currencies "stickier" and muting the speed and magnitude of potential appreciation.

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.

For nations facing acute liquidity stress, such as Maldives with its large 2026 bond maturity, traditional economic analysis is insufficient.

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.

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.
