The rupiah exchange rate against the US dollar weakened 0.05 percent to Rp16,790 per dollar at the opening of trading on Tuesday, January 27, 2026. The Composite Stock Price Index (IHSG) also opened down 0.31 percent at 8,947, though it is predicted to potentially strengthen if it holds the support level. This movement is influenced by geopolitical tensions between the US and Canada regarding trade with China.
On Tuesday, January 27, 2026, the rupiah exchange rate against the US dollar showed fluctuations at the start of trading. According to Bank Indonesia's Jakarta Interbank Spot Dollar Rate (Jisdor) data, the rupiah rate stood at Rp16,779 per dollar on Monday, January 26, 2026, strengthening 59 points from Rp16,838 on the previous Friday. However, in the spot market until 09:06 WIB, the rupiah weakened 8 points or 0.05 percent to Rp16,790 per dollar from the previous level of Rp16,782.
Economist observer Ibrahim Assuaibi stated that the market supports Bank Indonesia's (BI) commitment to maintaining rupiah stability through large interventions in the offshore NDF, DNDF, and spot markets. "BI believes it will remain stable in the future with a strengthening tendency thanks to attractive yields, low inflation, and continued good economic growth prospects," he said. Sufficient foreign exchange reserves are also seen as supporting the rupiah's strengthening.
Meanwhile, the IHSG opened down 28 points or 0.31 percent at 8,947. Fanny Suherman from PT BNI Sekuritas predicts the IHSG has potential to continue strengthening if it holds the 8,880 support. "IHSG support is at the 8,880-8,900 level while resistance is in the 9,000-9,050 range," she said.
Indonesia's market movements align with mixed Asia-Pacific exchanges on Monday, triggered by geopolitical concerns. US President Donald Trump threatened 100 percent tariffs on Canadian goods if Ottawa strikes a trade deal with China. Canadian Prime Minister Mark Carney affirmed, "We have no intention of doing that with China or other non-market economies," while respecting the CUSMA agreement.
In Wall Street, the S&P 500 rose 0.50 percent, Dow Jones 0.64 percent, and Nasdaq 0.43 percent, driven by tech stocks like Apple which surged 3 percent.
