Japan's three largest banks—MUFG, Sumitomo Mitsui, and Mizuho—have collectively boosted their foreign currency liquidity buffers to $1.25 trillion as of August 9, 2026. This move is seen as a precautionary measure anticipating sudden demand for U.S. dollars amid ongoing tensions related to the Iran conflict. The increased liquidity aims to ensure stability and readiness in the face of potential market disruptions.

The banks' actions reflect broader concerns in East Asia about geopolitical risks and their impact on financial markets. The liquidity buffers are intended to provide a robust financial cushion to manage unexpected currency demands.
