The Philippines' key index lost 1.2 per cent while Jakarta's Composite Index eased 0.7 per cent, both reversing gains on the previous session that were helped by selective buying in a reporting season.

"Any rebound will be unstable as investors minimise activities ahead of the US FOMC meeting results released tonight and also the ECB meeting Tuesday. Locally, political uncertainties remain as parliament is going to reconvene this Thursday," broker KGI Securities said about Thailand in a report.
