Jakarta, 9 March 2026 – Indonesian financial markets came under intense pressure as the country’s benchmark equity index and currency weakened sharply following escalating geopolitical tensions in the Middle East, with investors fleeing emerging-market assets amid surging oil prices and rising global uncertainty.
The sell-off saw Indonesian stocks decline while the rupiah slipped against the U.S. dollar, reflecting growing concerns among investors about the economic fallout from the widening conflict involving Iran and its potential disruption to global energy supplies.
The downturn in Indonesia’s markets mirrors a broader wave of volatility sweeping across global equities as the conflict sent crude oil prices soaring above US$100 per barrel, fuelling fears of inflation and slower global growth.
Oil Shock Sends Shockwaves Across Emerging Markets
The escalation in the Middle East has triggered one of the largest oil price spikes in recent years. Benchmark crude prices surged more than 20%, reaching levels not seen since 2022 as investors feared disruptions to supply routes, particularly through the strategically crucial Strait of Hormuz, which handles roughly a fifth of global oil shipments.
For emerging markets like Indonesia, the sudden surge in energy prices carries significant economic implications. Higher oil costs can increase inflation, weaken currencies and widen fiscal pressures, particularly for economies that rely heavily on imported fuel.
As a result, investors rapidly shifted funds into safe-haven assets such as the U.S. dollar and government bonds, triggering a broad sell-off in riskier markets.
Rupiah Weakens as Capital Flows Shift
The Indonesian rupiah also faced downward pressure as global investors retreated from emerging market currencies.
Analysts noted that currencies across Asia weakened as the stronger U.S. dollar and rising geopolitical risks prompted investors to reallocate capital toward safer assets.
Indonesia’s central bank has reportedly intervened in financial markets in recent days to stabilize the rupiah amid heightened volatility caused by the geopolitical turmoil and rising oil prices.
Currency instability often amplifies market volatility because a weaker rupiah raises concerns about inflation and foreign capital outflows.
Indonesian Equities Hit by Global Risk-Off Sentiment
Indonesia’s benchmark Jakarta Composite Index (JCI) also declined as investors trimmed exposure to equities across Asia.
Analysts said the sell-off was largely driven by global macro developments rather than domestic economic deterioration. Rising oil prices and geopolitical uncertainty have historically triggered “risk-off” sentiment among investors, prompting them to reduce exposure to emerging markets.
The Indonesian market has already faced volatility in recent weeks due to geopolitical tensions and concerns about fiscal outlook following changes in government economic policies.
Brokerage analysts warned that the JCI could remain volatile in the near term as investors monitor developments in the Middle East and global commodity markets.
Asia Markets Under Pressure
Indonesia was not alone in facing market turbulence. Equity markets across Asia and globally also weakened as investors reacted to the escalating conflict.
U.S. stock futures dropped sharply while major Asian benchmarks posted steep losses, reflecting widespread anxiety about the economic impact of rising energy prices and geopolitical uncertainty.
Analysts warn that sustained oil prices above US$100 could increase inflationary pressures worldwide and complicate monetary policy decisions for central banks.
Outlook: Markets Watching Oil and Geopolitics
Despite the current volatility, economists say Indonesia’s longer-term fundamentals remain relatively stable. However, the immediate outlook for markets will largely depend on developments in the Middle East conflict and the trajectory of global oil prices.
If tensions escalate further and oil prices continue rising, emerging markets could face prolonged capital outflows and currency pressure.
For now, investors remain cautious as geopolitical risks reshape global financial markets and test the resilience of emerging economies across Asia.
