The rupiah is more than just a number displayed on financial market screens. Its value reflects the level of confidence in Indonesia’s economy. When global pressures intensify and confidence in domestic economic prospects weakens, the exchange rate responds quickly.
On May 20, 2026, Bank Indonesia raised its benchmark interest rate by 50 basis points to 5.25 percent after the rupiah traded around IDR 17,700 per US dollar the previous day. The move reflected the central bank’s commitment to maintaining currency stability amid increasing external pressures.
History shows that the rupiah’s trajectory has consistently been shaped by two major forces: external shocks and domestic fundamentals. The Asian Financial Crisis of 1997–1998 demonstrated how currency depreciation can evolve into a broader economic, political, and social crisis when accompanied by panic and declining public confidence. Since then, the rupiah has faced renewed pressures during the 2008 global financial crisis, the 2013 taper tantrum, the COVID-19 pandemic, global monetary tightening cycles, and the economic volatility experienced in 2026.
However, equating current conditions with the 1998 crisis would be misleading. Indonesia’s economic structure is considerably stronger today. The banking sector is healthier, foreign exchange reserves are larger, inflation remains relatively contained, and the exchange-rate regime is more flexible than it was during previous crises. The most relevant similarity lies not in the severity of the crisis itself, but in the lesson it provides: markets can tolerate external pressures, but they react negatively to unclear or inconsistent policy signals.
In this environment, policy consistency becomes critical. Bank Indonesia must not only maintain stability through monetary instruments such as foreign exchange intervention, Domestic Non-Deliverable Forward (DNDF) transactions, and other market operations, but also communicate policies consistently and credibly. Confidence in economic authorities remains one of the most effective tools for limiting excessive volatility.
The private sector also has an important role to play. Companies with foreign-currency liabilities need to strengthen hedging strategies. Importers should improve procurement and pricing arrangements, while exporters need to build natural hedges by strengthening their business structures. A weaker rupiah is not only a challenge for households, but also a test of corporate preparedness in managing global economic uncertainty.
Some observers argue that a weaker rupiah benefits exports. In theory, this argument is valid. However, such benefits materialize only when industries possess strong production capacity, low import dependency, efficient logistics systems, and reliable market access. When raw materials, energy, machinery, and financing remain heavily dependent on US dollars, currency depreciation can instead increase production costs and weaken competitiveness.
The key lesson from the rupiah’s history is that exchange rates are influenced not only by market sentiment but also by confidence in economic policy and national fundamentals. Therefore, the government must maintain fiscal discipline, Bank Indonesia must preserve policy credibility, and businesses must strengthen risk management practices. The rupiah does not need to be strong every day, but it must be managed through policies that sustain public and market confidence in the direction of Indonesia’s economy.
