The Hong Kong dollar fell on Friday with local interbank rates generally lower, prompting arbitrage traders to chase higher yielding currencies. The local currency was trading at 7.7782/83 to the US dollar, down from Thursday's local close of 7.7771/72.
Under the territory's linked exchange rate system, the Hong Kong dollar can trade between 7.75 and 7.85 to the US dollar.

Lower US bond yields overnight also helped the longer-dated local interbank rates to soften, dealers said. The one-month interbank rate fell to 4.00/4.05 percent from 4.05/4.10 percent late on Thursday.
The three-month rate quoted at 4.19/4.24 percent. The gap between the three-month US interbank rate and the Hong Kong rate was 116 basis points, widening from 112 basis points on Thursday. The one-year rate fell to 4.40/4.45 percent from 4.44/4.49 percent at the previous close.
Arbitrage traders were selling Hong Kong dollars for US dollars to take advantage of the interest rate differential. One dealer at a local bank expected the Hong Kong dollar to move between 7.7750 and 7.7790 in the near term and said the downside would be capped by expectations for fund inflows for upcoming IPOs.
