TAIPEI, Oct 3 (Reuters) - Taiwan's central bank said on Tuesday that it sold a net $880 million to intervene in the forex market in the first half of this year.

Taiwan's central bank last year sold a net $13 billion to intervene in the foreign exchange market to try and prop up the Taiwan dollar, compared with buying a net $9.12 billion for all of 2021.

The Taiwan dollar has lost about 5% of its value against the greenback so far this year. (Reporting by Liang-sa Loh and Faith Hung; Editing by Ben Blanchard and Muralikumar Anantharaman)
