The Indonesian Rupiah weakened against the US Dollar following the release of disappointing Purchasing Managers' Index (PMI) data from China. According to FX Street, the USD/IDR pair traded around 18,120 during Asian hours on Friday as investors reacted to the economic signals from China.

The slowdown in China's manufacturing sector weighed on regional currencies, including the Indonesian Rupiah, reflecting concerns over reduced demand and economic growth prospects. This movement highlights the sensitivity of emerging market currencies to developments in China, their major trading partner.

For Japanese investors, the Rupiah’s decline underscores the interconnectedness of Asian markets and the potential impact of Chinese economic data on FX and equity markets across the region.
