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.

Many Asian economies use fiscal policy and reserves to subsidize oil prices for consumers. While this initially dampens the shock, it creates a mixed and delayed effect on inflation and growth, making it difficult for policymakers and investors to predict the ultimate economic consequences.

Asia is uniquely vulnerable to the current energy crisis not just from price increases but from physical supply shortages—a factor rarely modeled in past shocks. This dual risk poses a more significant threat to economic growth than in other regions, with some economies already facing rationing.

Unlike the 2022 energy shock post-Ukraine invasion, the current market is not emerging from a decade of zero interest rates. U.S. real rates are already positive, and EM economies have built up buffers after being stress-tested, making a repeat of 2022's widespread defaults less likely.

Markets often over-focus on relative interest rate policy when analyzing currencies. During an energy crisis, the macroeconomic effect of rising oil prices is a far more powerful driver. The disproportionate negative impact on energy-importing economies like Japan and Europe will weigh on their currencies more than any central bank actions.

The economic impact of high energy prices is manageable and relatively linear. However, a physical shortage of oil and gas, where supply is simply unavailable, would create a non-linear, catastrophic shock for Asian economies heavily reliant on Middle Eastern imports.

China is insulated from the worst effects of an oil shock due to its state-controlled supply chain. It can activate coal gasification facilities when crude prices exceed $100 and toggle its power grid between gas, surplus coal, and solar, minimizing the impact on economic growth.

When emerging economies borrow in U.S. dollars, they are unknowingly making a bet that oil prices will remain stable. A spike in oil strengthens the dollar and weakens their local currency, simultaneously making their debt more expensive to service just as energy import costs soar.

While media focuses on Europe and Japan, the IEA head highlights that the biggest victims of the energy crisis are developing countries. Lacking hard currency to compete for expensive oil and gas, they face severe economic strain, potential energy rationing, and a repeat of the 1970s foreign debt spirals.
