In March, the PCE core inflation – which does not include food and energy prices – was 2.7 percent according to revised figures.
If you include food and energy prices, the PCE inflation fell to 2.1 percent in May, compared to expected 2.2 and 2.3 percent in April.
The PCE inflation is seen by the US central bank Federal Reserve (Fed) as the most important price increase measure when decisions on future interest rates are to be made.
In contrast to the more common CPI measure of inflation, which is based on a basket of goods, the PCE inflation is calculated on what is actually consumed.
The Fed's inflation target is 2 percent.
