Iran War Drives Oil and Reserve Depletion; Philippines and India Hit as Energy Importers Defend Currencies

The geopolitical escalation in the Iran-Middle East region is triggering a secondary energy shock that ripples far beyond oil price charts. Energy-importing economies across Asia are hemorrhaging foreign-exchange reserves as they attempt to defend their currencies against surging crude and refined product costs. The Philippines and India are among the most exposed, with current-account pressures mounting and reserve coverage dwindling month after month.

The mechanics are brutal. As oil prices spike, import bills rise denominated in dollars. Central banks face a choice: allow their currencies to depreciate (risking pass-through to inflationThe rate at which prices rise across an economy. and eroding household purchasing power) or spend reserves to support the currency and absorb the shock. Most have chosen a mix of both, but the reserve burn is accelerating. Bangladesh's credit rating was already downgraded by Fitch on May 13 for precisely this reason; the country's vulnerability to Middle East shocks and energy costs triggered a shift to negative outlook.

Data from the Bloomberg energy shock tracker shows that flows through the Strait of Hormuz fell nearly 6 million barrels per day in the first quarter of 2026, a seismic 30% decline from prior levels. This is not a cyclical blip; it reflects genuine supply disruption and rerouting of cargoes. Energy prices at the pump, heating oil, diesel, and shipping costs are all elevated, feeding through into broader inflationThe rate at which prices rise across an economy. and reserve depletion for countries without domestic energy production.

The cross-asset implications are profound. Reserve depletion limits monetary policy independence for central banks in Asia; they may be forced to tighten policy to defend their currencies even as growth slows, creating a stagflationary trap. For equity markets, energy stocks and multinational commodity traders benefit, while consumer discretionary and cyclical plays in energy-importing nations face pressure. For currencies, the Indian Rupee, Philippine Peso, and Bangladesh Taka are all at risk of sustained depreciation if the energy shock persists.
