USD/IDR gains ground for the second successive day, trading around 18,190 during early European hours on Tuesday. The pair appreciates as the Indonesian Rupiah (IDR) struggles under widespread cautious sentiment, driven by fiscal pressures from rising oil prices, volatile export earnings, and shifting external demand. In response, Bank Indonesia (BI) has reaffirmed its commitment to strengthening policy coordination with the government while maintaining a balanced policy mix to support the domestic currency.

The upside of the USD/IDR pair could be restrained as the US Dollar (USD) struggles ahead of the US midterm elections. Political pressure on US President Donald Trump and the Republican Party has mounted due to elevated energy prices linked to ongoing conflicts with Iran. Meanwhile, prediction markets currently reflect a 74% probability of the Democratic Party gaining control of the US Senate, highlighting the elevated political stakes surrounding the vote.

Meanwhile, market participants are keeping a close watch on the upcoming US jobs report scheduled for release later this week. The employment data is expected to offer fresh insights into labor market health and help shape expectations for future monetary policy decisions. The Federal Reserve has maintained a hawkish stance, with the CME FedWatch Tool currently pricing in roughly a 75% chance of a rate hike in December following a policy pause in October.

US Dollar seen resilient as RBA hit weighs on Aussie

Strategists at ING argue that the outcome of today’s US midterm elections is unlikely to be a major driver for foreign exchange markets, noting that they “don’t expect today’s US midterm results to cause structural shifts in FX.” They do, however, flag some near-term political risk for the Dollar, with the currency potentially facing “some short-term pressure should the Democrats secure both the House (widely expected) and the Senate (close call).”

Turning to Australia, ING highlights that “a dovish hike by the RBA has hit AUD,” but the bank’s analysts “remain optimistic on the outlook for the currency beyond the near term,” suggesting that recent weakness in the Aussie may prove temporary once the immediate policy surprise is absorbed.

Indonesian Rupiah FAQs

What are the key factors driving the Indonesian Rupiah?

The Indonesian Rupiah (IDR) is sensitive to a dynamic mix of global market conditions, domestic economic fundamentals, commodity price shifts, and proactive central bank interventions. As an emerging market currency, the Rupiah’s trajectory depends heavily on both domestic resilience and international economic momentum.

How do decisions of the Bank Indonesia impact the Indonesian Rupiah?

Bank Indonesia (BI) plays a central role in stabilizing the Rupiah through strategic monetary policy and direct market operations. By adjusting benchmark interest rates, the central bank manages yield differentials against major global central banks like the US Federal Reserve to attract and retain foreign portfolio investments. BI also utilizes a "triple-intervention" framework—operating across spot, derivative (DNDF), and government bond markets- to smooth out currency volatility, complemented by monetary instruments like Sekuritas Rupiah Bank Indonesia (SRBI) to bolster capital inflows.

What macroeconomic factors influence the value of the Indonesian Rupiah?

From a broader macroeconomic perspective, domestic inflation rates, trade performance, and overall fiscal health dictate the IDR's underlying strength. Indonesia's trade and current account balances are closely tied to these fundamentals, while broader global factors, such as risk-on or risk-off sentiment among international investors and global liquidity trends, directly affect exchange rate movements.

How do global commodity prices impact the Indonesian Rupiah?

As a major exporter of commodities such as palm oil, coal, nickel, and natural gas, Indonesia benefits from higher global commodity prices, which generate trade surpluses, increase foreign currency inflows, and strengthen the Rupiah. However, because Indonesia is also a net importer of crude oil, elevated global oil prices increase the foreign exchange burden, widening the current account deficit and weighing on the currency's value.

AUD/USD drops to two-week low, further below 0.7000 after RBA's less hawkish rate hike

AUD/USD drifts lower for the second straight day on Tuesday, hitting a fresh two-week low during the Asian session after the Reserve Bank of Australia's (RBA) widely expected 25 bps rate hike. The decision was far from unanimous, with three members preferring to hold rates at 4.60%. This tempers expectations of further tightening, which, along with modest US Dollar strength, weighs on the currency pair.

USD/JPY fails near 159.00 amid weak USD, intervention risks

USD/JPY edges lower during Tuesday’s Asian session, reversing part of the previous day's gains to 158.00 as the US Dollar remains depressed amid hopes for Iran diplomacy and ahead of US midterm elections. Meanwhile, intervention risks support the Japanese Yen, though the uncertainty over the timing of the next BoJ rate hike caps gains. This keeps the pair confined within a familiar range and warrants caution before placing directional bets.

Gold struggles below $3,950 amid Fed hike bets, ahead of US midterm elections

Gold weakens further below $3,950 during the Asian session, reversing part of the previous day's recovery from a one-year low set last week. Data released on Monday showed that US manufacturing sector business activity expanded for the 10th straight month in October. The Institute for Supply Management's Manufacturing PMI came in higher than consensus estimates and rose to 55.5 in October from 54.5 in the previous month. This reaffirms hawkish US Federal Reserve expectations, which along with rebounding US bond yields, prompt fresh selling around the non-yielding yellow metal.

Cardano extends losses as sellers stay in control

Cardano (ADA) extends correction, trading below $0.189 on Tuesday after losing key support zone the previous day. Mixed derivatives data and cautious on-chain metrics continue to weigh on bullish sentiment, while weakening technical indicators suggest further downside risks for ADA.

What a split Congress means for the US Dollar

The United States is going to the polls on Tuesday, and much is at stake. The mid-term elections mean the renovation of roughly one-third of the Senate and all 435 of the House seats. Additionally, special elections in Florida and Ohio will be held to fill the seats vacated by US Secretary of State Marco Rubio and Vice President JD Vance.

The 2% inflation target came from a throwaway remark. It now moves trillions

The Federal Reserve's 2% inflation goal grew out of an off-the-cuff remark by a New Zealand politician in 1988. Bond investors still price long-term US debt as if 2% holds, so a change in how the Fed measures inflation would move markets.
