A formula, not a fresh discretionary vote
The Hong Kong Monetary Authority said on 17 September that the Base Rate had been set at 4.25 per cent with immediate effect according to a pre-set formula. The rate is the higher of 50 basis points above the lower end of the prevailing US federal funds target range and the average of the five-day moving averages of overnight and one-month HIBORs. After the 25-basis-point upward adjustment in the US target range on 16 September US time, 50 basis points above the lower end equalled 4.25 per cent, while the HIBOR average was 2.50 per cent, so the Base Rate was set at 4.25 per cent.[1]
