The Hong Kong dollar fell to a two-and-a-half week low on Tuesday, undermined by weakness in the local equity market and speculation on a link between the local currency and the Chinese yuan at some point in the future.
The Hong Kong dollar was trading at 7.7731/33 per US dollar, off an intraday low of 7.7737 but still down from 7.7709/10 in late Asia trade on Monday.
Hong Kong stocks closed at their lowest level this month on Tuesday, down 1.6 percent, with bellwether stock Hutchison sliding on a growing perception the company would post weak earnings later this week.
