USD/IDR stayed soft for a fourth day, trading near 18,040 in Asian hours as the rupiah firmed on stronger Indonesian data and a weaker US dollar. Indonesia’s S&P Global Manufacturing PMI rose to 50.2 in July from 46.9 in June, the best reading since February, as output edged up after four months of contraction and new orders steadied following June’s drop. Inflation also cooled: headline CPI eased to 2.88% year on year from 3.34%, below expectations of 3.2% and within Bank Indonesia’s 1.5%–3.5% target band, while core inflation held at 2.76% and monthly prices fell 0.14% versus forecasts for a 0.1% rise, marking the first monthly deflation since January.
The dollar also slipped after Japan confirmed coordinated yen-buying intervention with the US, while Bank of Japan figures pointed to spending of up to $58.97 billion and Tokyo reiterated readiness to act again. Elsewhere, the FXS Speechtracker scored Barkin’s remarks at 6.2/10 versus a 5.4/10 historical average, and the FXS Fed Sentiment Index fell 0.46 points to 148.24, still above the neutral 100 level. Separately, improved risk appetite followed reports that President Donald Trump paused planned strikes on Iran, as talks were said to focus on Iran’s nuclear programme and reopening the Strait of Hormuz.
Derivative Strategy on Improved Indonesian Fundamentals
We see a strong case for derivative traders to position for further downside in the USD/IDR pair, which is currently hovering around the 18,040 level. Indonesia’s domestic economic resilience is highly visible as the S&P Global Manufacturing PMI rebounded to 50.2, signaling a healthy return to expansion. We recommend utilizing short USD/IDR forward contracts or purchasing USD put options to capitalize on this mounting Rupiah strength.
With Indonesia’s headline annual inflation cooling significantly to 2.88% in July, the country’s real yields remain highly attractive to international investors. Historically, when Bank Indonesia maintains a steady benchmark rate—which stood at 6.25% during its defense of the currency in 2024—such low inflation drastically widens the real yield spread over the US. This favorable yield differential suggests we should expect sustained debt inflows into Jakarta, keeping the local currency well-supported.
Dollar Weakness and Broader Global Tailwinds
On the global front, the US Dollar is facing severe headwinds after coordinated foreign exchange interventions, with the Bank of Japan deploying up to $58.97 billion to prop up the Yen. This massive intervention, combined with eased geopolitical anxiety in the Middle East following diplomatic pauses, has cooled safe-haven demand for the Greenback. We believe derivative traders should exploit this broader Dollar weakness by establishing short-dollar positions against high-yielding emerging market currencies.
Furthermore, Fed official Thomas Barkin’s cautious “close call” remarks on interest rates indicate that US policymakers are hesitant to hike further, keeping Dollar bulls on the defensive. To navigate this hesitant Fed stance and shifting global risk appetite, we favor employing bearish USD/IDR option spreads to limit premium risk while capturing downward momentum. Over the coming weeks, closely monitoring US labor data and Indonesian trade balances will be crucial to timing these derivative entries.
