Indonesian Rupiah strengthens as lower oil prices push USD/IDR down

• Oil prices retreat following Trump's Middle East remarks, easing energy costs and weakening the US Dollar as USD/IDR declines.
• Robust US Nonfarm Payrolls and 78%+ odds of a December Fed rate rise limit the US Dollar's losses.
• Bank Indonesia intervenes to contain volatility as high crude costs strain Indonesia's fiscal outlook.

Easing energy prices are putting pressure on the US Dollar (USD), leaving USD/IDR trading near 18,100 in Monday's Asian session. The pair is retreating after recording a modest advance the previous day.

US President Donald Trump's comments on Iran prompted a retreat in crude oil. He described further military action against Iran as "highly unlikely," provided progress on Iran's nuclear programme continues and the Strait of Hormuz stays open. Trump also acknowledged that the unpopular conflict in the Middle East had earlier pushed up energy costs and contributed to recent Republican losses in the midterm elections.

Strong US labour market figures nevertheless constrain the Greenback's potential losses, having reinforced expectations of further monetary tightening. Market pricing now puts the probability of a 25-basis-point rate rise at December's Federal Open Market Committee (FOMC) meeting above 78%, according to the CME FedWatch tool.

October Nonfarm Payrolls (NFP) strengthened the hawkish outlook for the Fed: employment rose by 165,000, well above the consensus forecast of 65,000 and following September's revised increase of 60,000. At the same time, the Unemployment Rate eased to 4.1%, below the 4.2% forecast. For clearer indications of the Federal Reserve's policy path, investors now turn to Tuesday's Consumer Price Index (CPI) release and Friday's Producer Price Index (PPI) report.

Indonesia's position as a net oil importer leaves its fiscal conditions under strain from elevated oil prices, which may put downward pressure on the Indonesian Rupiah (IDR). Bank Indonesia (BI) responded to the continuing currency volatility with active intervention in the foreign exchange market to moderate exchange rate swings. Foreign exchange reserves consequently rose marginally to USD 146.8 billion in October.

Forthcoming developments in equities are also drawing market attention. Alongside MSCI's November review later this week, traders await updates on its eventual decision about Indonesia's market classification, expected by June 2027.

US labour data averages indicate full employment consistent with the Fed's assessment

A longer-term view offers a better way to assess recent swings in monthly payroll figures, according to Commerzbank analysts, who observe that “given these fluctuations, it makes sense to look at averages over several months.” They note that “over the past six months, payrolls have risen by an average of 83,000 per month,” an increase that “may not seem like much” initially. With immigration “significantly lower,” however, they regard that pace as “enough to keep the unemployment rate steady at just over 4% – a level the Federal Reserve considers consistent with full employment.”
