Kazakhstan's net gold and foreign currency reserves fell to $33.8 billion as of May 31 from $34.5 billion on April 30, due mainly to a weaker euro, the central bank said on Wednesday.

The reserves are still more than 17 percent greater than at the end of last year, data released by the central bank showed.

The National Fund, replenished by windfall revenues from oil exports, totalled $51.6 billion as of May 31, the bank said in a statement. This was up from $51.0 billion at the end of April.

The central bank has provided the following data for its reserves since the end of 2008:
