The Indonesian Rupiah (IDR) declined against the US Dollar (USD), with USD/IDR trading around 17,940 during European hours on Monday after recovering from previous losses [1]. This depreciation is attributed to Indonesia's policy trade-off between stimulating economic growth and defending the currency, compounded by a persistent current account deficit and tighter global financing conditions, which leave the Rupiah vulnerable to shifts in foreign capital flows [1]. Despite retail sales expanding at their fastest pace in five months in August, consumer confidence retreated from its recent peak, indicating uncertainty in underlying demand [1]. Inflationary pressures are mounting, with headline inflation reaching a three-month high in September and rising food costs expected to sustain upward price pressure through year-end [1]. Foreign exchange reserves dipped slightly but remain near a five-month high, providing some buffer against market volatility [1].
Meanwhile, the US Dollar Index (DXY) trades almost flat at around 102.22 during European hours, maintaining a bullish near-term bias after hitting a fresh yearly high at 102.54 last week [2]. Technical analysis shows the DXY holding above the 20-day EMA at 101.35, with the Relative Strength Index (RSI) at 70.65 indicating strong upside momentum but vulnerability to consolidation or a corrective pause [2]. Analysts at MUFG/BTMU note that major currency pairs have remained stable overnight, with the Dollar index trading close to year-to-date levels just above 102.00, underscoring the Dollar's tendency to hover near familiar ranges [1][2].
Market participants are cautious ahead of the US Consumer Price Index (CPI) data for September, scheduled for release on Wednesday, which is expected to significantly impact Federal Reserve (Fed) interest rate expectations [2]. The headline CPI is forecast to accelerate to 3.7% year-on-year (YoY) from the previous reading of 3.4%, while core CPI is expected at 2.5% YoY, up from 2.4% [2]. According to MUFG/BTMU, unless there is a significant upside surprise in underlying inflation, the Fed is expected to leave rates on hold this month [2]. The CME FedWatch tool shows the probability of a rate hike of at least 25 basis points this month has dropped to 17.7%, down from 24.4% the previous week, while an 84.1% chance of a rate increase at the Fed's December meeting is strongly priced in [1].
Geopolitical developments in the Middle East have resurfaced as a risk factor, with US President Donald Trump indicating consideration of joining Saudi Arabia in its military campaign against Iran-backed Houthi militants in Yemen following another deadly attack on Riyadh's international airport [1].
CONCLUSION
The Indonesian Rupiah remains under pressure amid domestic policy challenges and external risks, while the US Dollar Index holds near yearly highs ahead of key US CPI data. Market sentiment is cautious, with traders awaiting inflation figures that could shape Federal Reserve rate expectations. Technical and fundamental signals suggest the Dollar's recent strength may consolidate, but volatility is expected around the CPI release.
