Rupiah Accelerates: Strengthens 0.53%, US Dollar Falls to Rp17,885
Jakarta, CNBC Indonesia — The rupiah closed sharply higher against the US dollar in trading ahead of the weekend on Friday (17/7/2026).
According to Refinitiv data, the rupiah ended trading at Rp17,885/US, up0.53.
The rupiah moved consistently in the green from the start of trading. The Garuda currency opened at Rp17,980/US$ and continued to strengthen until closing.
At the same time, the US dollar index (DXY), which measures the greenback’s strength against six major world currencies, weakened. As of 15:00 WIB, the DXY had slipped 0.07% to 100.695.
The rupiah’s strengthening today was in line with the weakening of the US dollar in global markets. The greenback is also on a weekly declining path after softer-than-expected US inflation data eased market concerns about a near-term interest rate hike by the US central bank (the Federal Reserve/The Fed).
Other economic data do show the US economy remains fairly robust, particularly with a relatively stable labour market. However, economists expect The Fed to hold interest rates steady at this month’s meeting after US consumer inflation cooled in June.
Fed officials remain cautious because the improvement in inflation has only been visible for a single month, following several months of increases. Fed Vice Chair Philip Jefferson even opened the door to a rate hike should inflation fail to show further improvement.
Based on the CME FedWatch Tool, the probability of a Fed rate hike in July now stands at 11%, down from 25% last week. Markets also expect cumulative rate increases of around 26 basis points by December, lower than the 44 basis points expected at the start of this week.
Beyond Fed policy, market players are still watching the renewed escalation of the conflict between Iran and the US. The two countries have stepped up attacks on each other over the past week, nearly collapsing last month’s ceasefire agreement.
The rupiah also received positive sentiment from Indonesia’s investment realisation, which continued to grow in the first half of this year.
The government recorded investment realisation for the first semester of 2026 at Rp1,010.6 trillion, up 7.2% year on year (yoy). That figure is equivalent to 49.5% of the 2026 investment target of Rp2,041.3 trillion.
“Investment realisation reached Rp1,010.6 trillion, growing 7.2%,” said Minister of Investment and Downstream Industry Rosan Roeslani at a press conference on Thursday (16/7/2026).
Of the total, domestic investment (PMDN) amounted to Rp502.9 trillion, while foreign investment (PMA) was slightly larger at Rp507.6 trillion. The sizeable share of foreign investment provides positive sentiment for the rupiah, as it shows foreign investors’ interest in the Indonesian economy remains intact.
