Yuan Hits 4-Year High, Prompting China's Central Bank to Raise FX Reserve Requirement Ratio from 4% to 6% - BigGo Finance

The Chinese yuan has reached a four-year high, prompting the People's Bank of China to raise the foreign exchange reserve requirement ratio for financial institutions from 4% to 6%. The move affects the share of foreign currency deposits that banks must hold in reserve rather than lend or deploy, effectively tightening the supply of foreign exchange in the domestic system.

The timing is notable. A stronger yuan can weigh on export competitiveness and encourage speculative capital inflows, and the central bank has historically used this tool to lean against rapid appreciation rather than to set a target for the currency. Raising the ratio makes holding foreign currency more costly for banks, which can cool upward pressure on the yuan without directly intervening in the market.

For observers, the key question is whether the adjustment slows the yuan's rise or merely signals official discomfort with its pace. Attention will center on the currency's subsequent moves, any further reserve-ratio changes, and broader capital-flow data. The episode illustrates how central banks can use reserve requirements as a flexible, incremental lever alongside interest rates and direct market operations.
