Jakarta, IDN Times – Bank Indonesia (BI) continues to intensify efforts to stabilize the rupiah amid ongoing market pressures. This commitment is reflected in the outstanding Bank Indonesia Rupiah Securities (SRBI), which have surged, nearing the Rp1,000 trillion mark. As of April 2026, outstanding SRBI reached Rp957.91 trillion, marking a significant year-to-date (ytd) increase of Rp227 trillion from the December 2025 level of Rp730.90 trillion.
The banking sector remains the primary holder of SRBI, accounting for 70.35 percent or Rp673.90 trillion as of April 2026. Non-bank investors represent 23.78 percent of the total. By investor category, foreign ownership stands at Rp192.17 trillion, while domestic investors hold Rp35.66 trillion, with the remaining Rp56.19 trillion held by other entities. Given this massive issuance, it is essential to examine the implications for the broader economy.
1. SRBI as a cornerstone of BI’s stabilization strategy
Yusuf Rendy Manilet, an economist at the Center of Reform on Economics (CORE) Indonesia, observes that SRBI has evolved from a supplemental tool into a vital component of BI’s stabilization framework.
“BI is currently heavily reliant on market instruments to protect the rupiah, and SRBI has become one of its primary tools. Reaching nearly Rp1,000 trillion signifies that this is no longer a minor instrument, but a centerpiece of their monetary approach,” Yusuf told IDN Times on Saturday (May 16, 2026).
2. Competitive yields to attract capital
According to Yusuf, utilizing SRBI provides BI with a strategic alternative to direct intervention in the foreign exchange market, which can rapidly deplete foreign exchange reserves. SRBI is designed to attract investor capital into rupiah-denominated assets by offering competitive yields with minimal risk.
“When investors channel their funds into SRBI, it naturally generates demand for the rupiah, which helps to buffer currency pressure,” he explained.
3. A multi-pronged approach to monetary stability
Beyond currency defense, SRBI plays a crucial role in absorbing excess banking liquidity. BI now coordinates a mix of foreign exchange intervention, Domestic Non-Deliverable Forward (DNDF), and SRBI as its primary stabilization package. While Yusuf views this strategy as effective in the short term—noting that the rupiah’s volatility remains relatively controlled compared to other emerging markets—he warns of potential trade-offs.
A primary concern is that banks may prefer placing funds in BI instruments rather than extending loans to the real sector. “If banks can earn a near-zero-risk yield of 6.5 to 7 percent through SRBI, the incentive to aggressively lend to productive sectors is inevitably reduced,” Yusuf noted.
4. The impact on credit growth and interest rates
This dynamic contributes to the currently sluggish credit growth. Furthermore, high SRBI yields prevent domestic interest rates from falling, keeping borrowing costs elevated for businesses. Yusuf also highlighted the rising interest costs BI must bear as SRBI outstanding grows. While not a direct burden on the state budget, these interest payments can weigh on the central bank’s profitability.
Ultimately, Yusuf suggests that SRBI serves as a “stop-gap” measure. “SRBI is effectively a way to buy time. As long as fundamental issues—such as policy uncertainty, balance of payments pressures, and weak long-term capital inflows—remain unaddressed, BI will continue to be the primary buffer for the rupiah.”
He concluded that maintaining the rupiah’s stability cannot rest solely on BI’s shoulders. The government must provide support through credible fiscal policies, a consistent investment climate, and the strengthening of long-term foreign exchange sources.
Summary
Bank Indonesia has significantly increased its issuance of Bank Indonesia Rupiah Securities (SRBI), with outstanding amounts reaching Rp957.91 trillion by April 2026. This instrument has become a cornerstone of the central bank’s strategy to stabilize the rupiah by attracting capital and absorbing excess banking liquidity. By offering competitive, low-risk yields, SRBI serves as a vital tool to manage currency volatility without rapidly depleting foreign exchange reserves.
However, economists warn that this reliance on SRBI may hinder economic growth by discouraging banks from lending to the real sector in favor of low-risk, high-yield central bank instruments. The high yields also sustain elevated borrowing costs, which contribute to sluggish credit growth and potential impacts on the central bank’s profitability. Ultimately, while effective as a temporary buffer, long-term stability requires government support through sound fiscal policies and structural reforms to address underlying economic imbalances.
