Indonesia on Thursday unveiled a raft of changes to stock market and banking regulations in an attempt to ease a liquidity crisis and bolster confidence after days of turmoil that triggered the suspension of share trading.

Sri Mulyani Indrawati, finance minister, said trading on the Jakarta stock exchange would resume on Friday after being halted on Wednesday following a 10.4 per cent drop in the benchmark index in only 90 minutes and a 21 per cent drop in three days.
