American Samoa's latest Consumer Price Index of 6.3 per cent, is one of the highest annual inflation rates for the territory.
The department of commerce says this level of high inflation seems to occur after cyclones, and federal assistance for victims is believed to drive up prices.
The cost of food jumped eight per cent, with the biggest increase in the price of meat.
Housing costs jumped 1.3 per cent and transportation costs increased by 1.4 per cent.
A slight increase was recorded for clothing, alcohol, tobacco and miscellaneous groups.
