Rupiah Today 18 May 2026: Weakens Further to Rp17,630

The exchange rate of the Rupiah against the US Dollar (USD) opened weaker in early trading on Monday, 18 May 2026. The Rupiah is experiencing pressure amidst global financial market dynamics.

Based on money market data on Monday morning, the Rupiah weakened by 33 points, or a correction of 0.19%, to the position of Rp17,630 per US Dollar. This figure represents a decline compared to the previous trading close, which stood at Rp17,597 per US Dollar.

The weakening of the Rupiah to the Rp17,630 level reflects the ongoing high volatility in the foreign exchange market. Factors influencing this movement include the release of solid US economic data and expectations regarding the US central bank’s (The Fed) interest rate policies, which remain a primary focus for market participants.

Currently, exchange rate movements continue to fluctuate in line with capital outflows in the domestic debt and equity markets. Market participants are advised to remain vigilant regarding the release of domestic economic data, which could serve as a catalyst to prevent further Rupiah depreciation.
