How Bad Could the Rupiah's Decline Become?

The Rupiah’s exchange rate has once again become a source of public anxiety. As the US Dollar breached Rp 17,600 (15/05/2026), the unease is no longer confined to bank dealing rooms or capital markets. The impact is beginning to spread to household kitchens, small stalls, tofu and tempeh producers, and MSMEs that rely on imported raw materials.

The question now is not merely why the Rupiah is weakening. The far more unsettling question is: how bad could the Rupiah’s decline truly become?

Amidst this situation, the public is actually reading something much larger than mere exchange rate figures. They are reading a sense of security, the future of purchasing power, and the possibility of essential commodity prices rising again. They are even reading the direction of the nation’s economic policy. Ultimately, the Rupiah is not just a currency symbol, but a symbol of confidence in Indonesia’s economic future.

Many still assume that the weakening of the Rupiah is solely a matter for financial markets. However, the ripple effects are very real in daily life. When the Rupiah weakens, import costs rise, raw material prices increase, and production costs are pushed upward, which then gradually exerts pressure on consumer goods prices.

Indonesia still relies on imports for many strategic needs: energy, soybeans, wheat, industrial raw materials, medical equipment, and technological components. In traditional markets, people may not discuss the term ‘Rupiah depreciation’, but they feel its impact in other forms: rising cooking oil prices, shrinking product sizes, increasing school fees, or slowly creeping transportation costs. At this point, the Rupah becomes a matter of economic psychology.
