The rupiah exchange rate against the US dollar on Thursday (22/7) is predicted to weaken following the correction in the regional exchange rate.

"The market is still worried about the increase in COVID-19 cases because of the delta variant, where Southeast Asia is considered to be the epicenter," said Money Market Observer Ariston Tjendra in Jakarta.

However, the weakening of the rupiah may be restrained as market sentiment towards risk appears to be improving.

"Global stock market is strengthening, there is market optimism towards improving company performance," said Ariston.

The rupiah has the potential to weaken to the range of 14560 per US dollar, with potential support in the range of 14520 per US dollar.
