The Hong Kong Monetary Authority cut its benchmark interest rate in line with the US Federal Reserve, an automatic response that’s unlikely to lend much support to the city’s sagging economy.

The HKMA on Thursday lowered its base rate to 2.5% from 2.75%, in step with the Fed’s quarter point move according to a “pre-set formula”, the monetary authority said in a statement

The HKMA on Thursday lowered its base rate to 2.5% from 2.75%, in step with the Fed’s quarter point move according to a “pre-set formula”, the monetary authority said in a statement. As the Hong Kong dollar is pegged to the greenback, the city essentially imports US monetary policy, though local banks aren’t obliged to follow with lower retail costs.

The first base rate reduction in more than a decade comes as the city is facing the economic downdraft from slowing global trade, China’s weakening expansion and political turmoil at home. Gross domestic product contracted 0.3% from the previous quarter, while growth on a year-ago basis remained at 0.6%, according to data released on Wednesday.

“It should help boost growth and financial sector activities after second-quarter’s weak print,” said Jeff Ng, Asia chief economist for Continuum Economics in Singapore. “However a small cut is unlikely to move the economy much. Hong Kong will have to rely on more Fed cuts for stronger support on the economy.”

The cut in isolation probably won’t push banks to lower prime rates, but if the Fed cuts more, there is a stronger chance local banks will do so, he said.

The HKMA is now in a transitional period, with chief executive Norman Chan set to be replaced in October by his long-time deputy Eddie Yue, who will have to face risks ranging from a resurgent property market to intermittent sniping against the city’s currency peg.

The base rate reduction also doesn’t help Hong Kong in dealing with its inflated property market, among the world’s most expensive.

“The base rate has no effect on banks’ liquidity, which remains very abundant,” said Stephen Chiu, a strategist at Bloomberg Intelligence in Hong Kong. “It’s very unlikely for Hong Kong banks to cut their prime rates given the city’s high property prices and strong housing demand.”
