Iran War Drains Asian FX Reserves; Philippines and India Hit Most as Crude Surges

The Iran war is reshaping Asia's economic landscape through an unexpected channel: currency defense. As crude oil prices spiked due to disruptions in the Strait of Hormuz and broader Middle East tensions, emerging-market central banks began burning through their foreign-exchange reserves to stabilize their currencies. This is particularly acute in the Philippines and India, which import substantial crude oil and have limited domestic energy production.

The FX reserve drain is a silent alarm bell. When central banks deplete reserves too rapidly, they lose the ability to defend their currencies in future crises, reducing policy flexibility and raising refinancing costs for government and corporate debt. India, already grappling with structurally high inflationThe rate at which prices rise across an economy. and current-account imbalances, is especially vulnerable. The Philippines faces similar pressures as energy costs erode fiscal space and household purchasing power declines.

Broader implications ripple across the region. Companies that import energy or rely on USD-priced inputs face margin compression. Exporters benefit from a weaker rupee or peso (enhanced competitiveness), but the net effect is deflationary for the region as a whole. Real estate and consumer discretionary sectors are likely to suffer as purchasing power erodes. By contrast, companies with USD earnings or energy-hedged balance sheets are insulated. Bonds issued by energy-importing sovereigns face widening spreads as investors price in higher refinancing risk.

The question is whether the Iran conflict will persist and continue to drive crude higher, or whether a negotiated ceasefire could allow oil prices to normalize and FX reserves to stabilize. If crude remains above $85, Asian central banks will continue to face painful reserve depletion, and growth forecasts for the region will face downward revisions.
