Indonesian Rupiah strengthens as US Dollar declines on potential Yen intervention

USD/IDR loses ground for the second successive day, trading around 17,730 during the Asian hours on Thursday. The currency pair experiences downward pressure as a sharp rally in the Japanese Yen (JPY) weighed heavily on the US Dollar (USD). This surge was fueled by growing market speculation that authorities conducted a rate check and may be preparing to intervene directly in foreign exchange markets.

Meanwhile, the Greenback faced additional headwinds following Wednesday's economic data, which revealed a slowdown in US private employment growth for August. Despite these weaker labor signals, financial markets continue to price in roughly a two-thirds probability that the Federal Reserve will raise interest rates later this month.

US private-sector job growth slowed in August, adding just 38K positions, missing the expected 47K and dropping below July’s revised 46K gain, according to ADP data. Market participants are now closely monitoring upcoming US economic indicators, focusing on Thursday’s weekly jobless claims and Friday’s comprehensive August payrolls report for clearer direction on the monetary policy path.

In Indonesia, Destry Damayanti, the first female governor of Bank Indonesia (BI), pledged to keep policy responsive to economic challenges while promoting stability and supporting growth. MUFG’s Lloyd Chan remains cautious on the Indonesian Rupiah as domestic inflation accelerates and Gross Domestic Product (GDP) growth stays above 5%. The trade balance has improved slightly but remains weaker than 2025 averages due to higher Oil and gas imports. While Bank Indonesia’s (BI) policy support and intervention framework offer near-term backing, sustained Brent prices above $90 could pressure Indonesia’s fiscal and external positions and weigh on IDR.
