FAP, May 15 / PRNewswire-FirstCall-Asianet /-- A sharp rise in Hong Kong dollar interest rates in the last month is driven by flows, as the aggregate balance of the Hong Kong banking system is at its lowest level since 2008, and because Hong Kong interest rates and Hong Kong interbank offered rates (Hibor) were too low in April, it is reasonable to see a gradual rise in Hibor in one month, according to a research report. At the same time, the increase may reflect temporary factors such as increased bank demand for capital, but given the peak of the US interest rate hike cycle and the recovery of the mainland economy, the risk of liquidity squeeze appears to be manageable.
