Jakarta — Bank Indonesia announced that the nation’s primary money supply, known as M0, expanded sharply in April 2026, climbing 14.3 percent year-on-year to reach Rp2,232.2 trillion.
The increase, driven by rising bank reserves and a surge in circulating currency, underscores both the strength of liquidity growth and the challenges facing policymakers as they balance economic stimulus with inflationary risks.
The central bank’s latest figures highlight two key drivers behind the expansion. Bank reserves at BI grew 21.6 percent compared with the same period last year, while currency circulating among the public rose 14.6 percent.
Together, these components pushed M0 to levels that analysts say reflect both seasonal demand and the impact of BI’s adjusted monetary framework introduced in early 2025.

Adjusted Framework for Transparency
Since January 2025, BI has applied a revised calculation for M0, designed to isolate the effects of liquidity incentives and provide a clearer picture of monetary conditions.
Officials argue that the adjustment enhances transparency, allowing markets to better interpret the central bank’s stance on liquidity management.
“The adjusted framework ensures that growth in M0 reflects genuine monetary expansion rather than distortions from temporary incentives,” one BI official noted.
The April figures follow a strong performance in March, when M0 reached Rp2,396.5 trillion, marking a 16.8 percent year-on-year increase.
While the pace of growth moderated slightly in April, the expansion remains well above BI’s stated target of maintaining M0 growth above 12 percent throughout 2026.
Implications for the Economy
Economists say the rise in primary money supply could support domestic demand, particularly in consumer spending and credit growth.
Higher reserves at BI suggest banks are holding more funds, bolstering financial stability and potentially enabling greater lending activity.
At the same time, increased cash in circulation points to stronger household demand, often linked to seasonal spending patterns.
Yet the expansion also raises concerns. Sustained liquidity growth, if not matched by robust economic fundamentals, could place downward pressure on the rupiah.
With global commodity prices volatile and external financing conditions tightening, Indonesia’s monetary authorities face the delicate task of ensuring liquidity does not fuel inflation or currency instability.
The surge in M0 comes as Indonesia navigates a complex economic environment.
Global oil prices remain unpredictable, while domestic inflationary pressures have edged higher in recent months.
BI’s commitment to maintaining liquidity growth above 12 percent reflects its dual mandate: supporting economic activity while safeguarding financial stability.
Analysts caution that the central bank must remain vigilant.
“Liquidity expansion is positive for growth, but the challenge lies in preventing overheating,” said one Jakarta-based economist.
“The rupiah’s stability will depend on how effectively BI manages the balance between stimulus and restraint.”
Looking ahead, BI’s adjusted reporting of M0 is expected to play a critical role in shaping market expectations.
By providing greater clarity on liquidity trends, the central bank aims to reinforce confidence in its monetary policy.
For businesses and households, the expansion signals continued support for economic activity.
For policymakers, however, it underscores the need for careful calibration in an uncertain global environment.
