Indonesian Rupiah struggles due to weak fundamentals, increased risk aversion

• Indonesian Rupiah slides due to weak July retail sales and consumer sentiment ahead of BI leadership transition.
• Safe-haven demand boosts the US Dollar amid renewed friction in US-Iran geopolitical talks.
• Markets await crucial US inflation data with September Fed rate hike expectations hovering near 50%.

USD/IDR extends its gains for the second successive day, trading around 17,920 during the European hours on Wednesday. The pair is advancing as the Indonesian Rupiah (IDR) faces pressure from weak domestic economic fundamentals and subdued market sentiment.

Both retail sales and consumer confidence in Indonesia remained muted in July, dampening IDR support. Investors are now turning their attention to Bank Indonesia’s upcoming monetary policy meeting next week, the first since former Governor Perry Warjiyo stepped down last month, where acting Governor Destry Damayanti has been nominated as the sole candidate for the leadership role.

IDR bearish momentum persists as BI meeting looms

Analysts at OCBC highlight that the “next BI meeting (19 Aug)” is the key event risk to watch for the Indonesian Rupiah, with “USDIDR last seen at 17762 levels.” They note that “bearish momentum on [the] daily chart [is] intact while RSI [has] fallen to near oversold conditions,” suggesting that while downside pressure on USD/IDR remains in place, the move is becoming stretched as markets look ahead to Bank Indonesia’s policy decision.

Meanwhile, the US Dollar (USD) is drawing strength from heightened safe-haven demand sparked by geopolitical uncertainties in the Middle East. While Pakistan’s defence minister suggested that Washington and Tehran were closing in on an agreement regarding the Strait of Hormuz, supported by reports of advanced negotiations between Iran and Oman, tensions flared after US President Donald Trump insisted that Tehran pay reparations to victims of attacks linked to the Islamic Republic, injecting fresh caution into global markets.

Looking ahead, market participants are keeping a close watch on the upcoming US inflation report set to be released later today, which is expected to heavily influence the Federal Reserve’s next interest rate move. Expectations regarding the Fed’s path forward remain split following its choice to hold rates steady in July. Although higher crude oil prices have strengthened the case for a firmer policy stance, the probability of a 25-basis-point rate hike in September has edged slightly lower, dropping to nearly 50% on the CME FedWatch Tool from over 52% a day earlier.

Goolsbee flags inflation as top risk but keeps Fed tone broadly hawkish

Fed’s Goolsbee scores 7/10 on the FXS Speechtracker, a clear uptick relative to the historical average of 5.8/10 and consistent with a firmer policy tone. By calling the labor market “stable, without being good” while stressing that “prices and affordability” and “inflation” are the biggest problems, the remarks lean toward prioritizing inflation control over labor-market concerns, implying a bias to keep policy restrictive even as growth risks are acknowledged. The emphasis that the economy will remain healthy “as long as the consumer remains healthy” underscores confidence in demand resilience, which supports a cautious stance on any early easing that could weaken the Dollar.

The FXS Fed Sentiment Index slipped by 0.42 points to 136.59, signaling a modest pullback in perceived hawkishness despite the still-elevated reading. With the index well above the 100 neutral mark, the Fed remains firmly in hawkish territory, and the small decline suggests markets see Goolsbee’s nuanced tone as slightly less aggressive on future tightening while still broadly supportive of a strong Dollar backdrop.
