Hong Kong shares dropped 1 percent Monday, weighed down by concerns that Beijing may step up efforts to cool its booming economy after it announced new credit tightening measures over the weekend.
The blue-chip Hang Seng Index fell 207.52 point to 20,318.98 points.
Investors sold Hong Kong stocks after China's central bank said Sunday it will raise banks' reserve requirement ratio by another half percentage point to 11 percent for most commercial banks.
The move, which comes after stronger-than-expected first-quarter economic growth, is the seventh increase within a year.
Investors worry that Beijing could roll out more measures, including interest rate hikes, in the coming weeks to contain rising inflationary pressures and slow growth from the first quarter's blistering pace.
Hong Kong's financial market will be closed Tuesday for Labor Day.
