Hong Kong's key measure of year-on-year inflation fell to 6.4 per cent in May, mainly as a result of lower food prices.
However, removing food costs from the index reveals that the underlying rate had been a consistent 6.6 per cent for the first five months.
The Government yesterday said the Consumer Price Index (A), the territory's broadest measure of inflation, fell 0.5 per cent from the previous month.
The index tracks the 50 per cent of Hong Kong households spending between $2,500 and $9,999 a month.
A Government spokesman said: 'It was mainly due to lower prices of some fresh food items, including vegetables and live poultry.' He said miscellaneous consumer services, such as the reduction in charges for long-distance telephone calls, helped ease inflationary pressure.
The territory is also benefitting from a slowdown in inflation in the domestic economies of its major trading partners.
In addition, the continued robustness of the US dollar, to which the Hong Kong dollar is pegged, eased any cost-push inflationary pressures arising from major trading partners.
