HKMA Raises Base Rate to 4.25%, Tightening Hong Kong Dollar Peg

Hong Kong's central bank raised its base rate by a quarter-point to 4.25%, mirroring the US Federal Reserve's move from a day earlier.

The decision is tied to Hong Kong's currency peg, which keeps the Hong Kong dollar in a tight band with the US dollar (7.75-7.85 per dollar).

This means that local interest rates are now aligned with US ones, but HKMA CEO Eddie Yue warned of potential pressure on the currency due to carry trades.

Carry traders borrow in Hong Kong dollars and hold US dollars to earn the difference between the two yields. If this flow increases, it can push the exchange rate toward the weak end of the band.
