The ringgit MYR fell almost 0.8% against the greenback, its steepest drop in seven months as investors reacted to the prospect of prolonged instability and compromise. The ringgit was last at 4.58 per dollar, off a two-month peak of 4.495 hit last week.

Muhyiddin's Perikatan Nasional alliance won 73 seats in the lower house - secured backing from two political blocs on Sunday as he sought to form a new government, though had yet to win the required majority.
