Bank Indonesia faces a growing policy paradox

Bank Indonesia’s decision to raise its benchmark BI Rate by 50 basis points to 5.25 percent marks a clear shift from supporting growth to defending macroeconomic stability as the rupiah comes under pressure. But the move also exposes a deeper dilemma: The central bank must stabilize the currency while sustaining growth, even as expansive fiscal intervention weakens monetary policy effectiveness and raises questions over its independence.

Since September 2025, BI had maintained its benchmark rate at 4.75 percent to support economic expansion. At the time, the accommodative stance remained manageable because global capital flows were relatively stable. That situation has now changed dramatically. Rising geopolitical tensions in the Middle East have widened the United States’ fiscal deficit and pushed US Treasury yields higher, encouraging investors to move capital away from emerging markets toward safe-haven assets.

Indonesia has become increasingly vulnerable to this shift. Although the economy appears stable on the surface, growth has become heavily dependent on government spending rather than strong private-sector activity. This raises concerns over fiscal sustainability, especially as large-scale flagship programs continue to absorb state resources.

The pressure intensified after MSCI warned Indonesia over governance and liquidity concerns in its equity market. Since the beginning of the year, foreign investors have recorded equity outflows exceeding Rp 27.64 trillion. The resulting capital flight pushed the rupiah to around Rp 17,719 per US dollar on May 19, its weakest level since the 1998 Asian Financial Crisis.

Facing mounting pressure from the capital outflow, BI increased yields on its rupiah securities, known as SRBI, by 100 basis points to attract foreign inflows. These measures helped generate approximately Rp 105.16 trillion in capital inflows between January and May, partially offsetting outflows from the equity market and weaker demand for government bonds.

However, the cost of stabilization is becoming increasingly visible. Indonesia’s foreign exchange reserves declined by around US$10 billion between December 2025 and April 2026, falling to $146.2 billion. Although reserves remain above international adequacy standards, continued intervention could erode this buffer if pressure on the rupiah persists.

At the same time, BI continues to maintain base money growth above 10 percent, an approach that appears inconsistent with its stabilization efforts. In practice, the central bank is being pressured to support the government’s flagship programs and broader growth agenda through accommodative liquidity policies. The government’s aggressive spending, however, creates inflationary pressure even as BI attempts to stabilize prices and defend the rupiah.

The situation may become even more challenging as the House of Representatives prepares revisions to the Law on the Development and Strengthening of the Financial Sector (P2SK Law). The proposed revision would explicitly add economic growth and employment creation to BI’s objectives.

Historically, BI’s primary mandate has been controlling inflation and maintaining the stability of the rupiah. Following the 1998 Asian Financial Crisis, Indonesia established an independent central bank as part of structural reforms agreed with the International Monetary Fund during the presidency of B.J. Habibie. Central bank independence was designed to prevent monetary policy from being excessively influenced by short-term political interests.

Expanding BI’s mandate further toward growth and employment risks reversing that reform legacy. In the short term, such coordination may appear beneficial. But over time, it could weaken market confidence, undermine policy credibility and reduce BI’s ability to respond effectively during periods of economic stress.
