From Tokyo to Seoul to New Delhi, Asian currencies are tumbling this year as governments burn through reserves defending their exchange rates. Japan has already spent more than $70 billion propping up the yen, with Finance Ministry officials signaling they're prepared to deploy even more firepower if needed.

Indonesia's central bank responded to capital outflows by hiking interest rates for the second time in three weeks at an emergency meeting. The moves aim to stabilize the Indonesian rupiah and stem the tide of money fleeing emerging markets for safer havens.

South Korea presents a stark contrast: the Korean won has fallen over 5% against the dollar this year despite an AI-driven export surge. Authorities are now cracking down on what they call excessive foreign-exchange speculation, scrutinizing trading patterns more closely.

The currency weakness boosts exporters and American tourists visiting the region, but it devastates importers and consumers already grappling with higher energy costs. Closure of the Strait of Hormuz threatens further oil price spikes, intensifying the economic pressure across import-dependent Asian economies.
