The Hong Kong Monetary Authority has kept its base rate at 4%, aligning with the US Federal Reserve's decision to maintain its benchmark interest rate in the 3.50% to 3.75% range.

The move underscores the rigid linkage between Hong Kong's monetary policy and Washington's stance under the city's currency board system.

The Federal Reserve concluded its latest policy meeting without adjusting the federal funds target, marking a continuation of its current hold cycle.

With the Fed holding steady, the HKMA's decision was effectively predetermined by the mechanics of the linked exchange rate system, which requires Hong Kong to mirror US rate moves to maintain the HKD/USD peg.

For market participants, the stability in the base rate removes immediate uncertainty from the local funding environment.

Hong Kong's interest rate structure remains anchored to US Treasury yields, meaning that any future shifts in the Fed's policy path will be transmitted directly to the city's borrowing costs.
