Hong Kong stocks fell on Thursday, bucking a rally across world markets, as another interest rate hike by the Federal Reserve forced the Monetary Authority to lift its own borrowing costs and put pressure on the city's already stuttering economy.

The Hang Seng Index dropped 0.2 percent, or 47 points, to close at 20,622.

The Shanghai Composite Index added 0.2 percent, or 6 points, to 3,282, while the Shenzhen Composite Index gained 0.4 percent, or 8 points, to 2,203. (AFP)
