Weakness in the US Dollar (USD) ahead of the US midterm elections may limit further gains in USD/IDR. Elevated energy prices stemming from ongoing conflicts with Iran have increased political pressure on US President Donald Trump and the Republican Party. Underscoring the high political stakes of the vote, prediction markets now assign a 74% probability to the Democratic Party taking control of the US Senate.

Attention is also turning to the US jobs report due later this week, which is expected to provide a fresh assessment of labour market conditions and inform expectations for subsequent monetary policy decisions. With the Federal Reserve retaining its hawkish stance, the CME FedWatch Tool currently indicates roughly a 75% probability of a December rate increase after an October policy pause.

Can the US Dollar stay resilient as the RBA weighs on the Aussie?

Today’s US midterm election outcome is unlikely to materially influence foreign exchange markets, according to ING strategists, who say they “don’t expect today’s US midterm results to cause structural shifts in FX.” Nevertheless, they see near-term political risks for the Dollar, warning of “some short-term pressure should the Democrats secure both the House (widely expected) and the Senate (close call).”

On Australia, ING notes that “a dovish hike by the RBA has hit AUD,” while its analysts “remain optimistic on the outlook for the currency beyond the near term,” implying that the Aussie’s latest weakness could be temporary once markets absorb the immediate policy surprise.

Indonesian Rupiah: frequently asked questions

Which key forces drive the Indonesian Rupiah?

Global market conditions, domestic economic fundamentals, movements in commodity prices and proactive central bank intervention together influence the Indonesian Rupiah (IDR). The path of this emerging market currency is shaped to a significant extent by Indonesia’s economic resilience as well as the pace of international economic activity.

How does Bank Indonesia’s policy affect the Indonesian Rupiah?

Strategic monetary policy and direct market operations make Bank Indonesia (BI) a key force in maintaining Rupiah stability. Changes to benchmark interest rates allow BI to manage yield differentials relative to major global central banks, including the US Federal Reserve, helping attract and retain foreign portfolio investment. To moderate currency volatility, BI also deploys a "triple-intervention" framework across the spot, derivative (DNDF) and government bond markets. Monetary instruments such as Sekuritas Rupiah Bank Indonesia (SRBI) complement these measures by supporting capital inflows.

Which macroeconomic conditions shape the Indonesian Rupiah’s value?

The IDR’s fundamental strength rests on domestic inflation, trade performance and the overall state of public finances. These macroeconomic fundamentals are closely linked to Indonesia’s trade and current account balances. At the same time, global liquidity trends and international investors’ appetite for or aversion to risk have a direct bearing on exchange rate movements.

How do changes in global commodity prices affect the Indonesian Rupiah?

Higher global commodity prices benefit Indonesia through its substantial exports of palm oil, coal, nickel and natural gas. The resulting trade surpluses and increased foreign currency inflows support the Rupiah. The oil price relationship is different, however: as Indonesia is a net crude oil importer, higher global oil prices add to its foreign exchange burden, widen the current account deficit and put downward pressure on the currency.
