On 12 May, Indonesia’s Finance Minister Purbaya Yudhi Sadewa confirmed that the government would enter the bond market the following day to assist Bank Indonesia (central bank) in stabilising the exchange rate. The announcement came after the rupiah touched its weakest level on record at 17,500 per US dollar.
The primary rationale of the decision, according to Minister Purbaya, is stabilising bond yields amid persistent pressure on the rupiah, which has been driven in part by turmoil in the Middle East. “We are managing it so that foreign [capital] doesn’t flow out,” he said, adding that steadying yields would “keep the domestic financial market stable”.
The intervention will be channelled through the Bond Stabilisation Fund (BSF). Under this mechanism, the government stands ready to purchase bonds from any investor seeking to sell. Crucially, the BSF will not draw on idle cash. Its funding comes from two sources: (1) excess budget surpluses, and (2) pooled funds from state-owned enterprises under the Ministry of Finance’s purview.
Despite the gravity of the measure, Minister Purbaya struck an optimistic note, expressing confidence in the central bank’s capacity to manage pressures. He framed the BSF deployment as a reinforcing move rather than a distress signal.
What does this mean for businesses?
The reasoning of this intervention is clear: a sharp drop in bond prices risks triggering a cascade of capital outflows, which would in turn force the state budget to absorb significantly higher interest obligations.
In practical terms, the BSF acts as a floor under the bond market, reducing the risk of a disorderly sell-off that could accelerate capital flight. For businesses with rupiah-denominated liabilities or import-heavy cost structures, this matters. A more stable exchange rate, even temporarily, eases pressure on margins and borrowing costs.
That said, this is a short-term buffer, not a structural fix. The BSF’s effectiveness depends on the scale and persistence of outflow pressures, while the underlying drivers (global risk sentiment and regional geopolitical uncertainty) remain unresolved. Businesses should monitor developments closely, particularly any shifts in foreign holdings of government securities.
