Singapore's stock market has been the least affected within Asia by the appreciating United States dollar, the Singapore Exchange said in a report on Wednesday.

Asian currencies have depreciated over the past month on market expectations of the Federal Reserve moving away from its stimulus measures.

The Singapore dollar, however, has remained relatively stable - the currency declined only 1.3 per cent against the US dollar over the past month, the SGX noted in its 'My Gateway' report.

Over the same period, the Indonesian rupiah has depreciated 9.4 per cent against the US dollar and the Indian rupee has depreciated 10.2 per cent. Meanwhile, the Malaysian ringgit and Thai baht have both depreciated 3.2 per cent to the greenback.

The relative resilience of the Singapore dollar means that in US dollar terms, the returns of the Straits Times Index (STI) have generally outperformed that of the benchmark indices of most Asian bourses, the SGX said.

In US dollar terms, the STI is now down 8.79 per cent for the year to date, while Thailand is down 11.71 per cent, Indonesia has dropped 21.66 per cent and India has fallen 25.63 per cent.
