India's five-year overnight index swap market recorded a massive ₹25,300 crore turnover on Wednesday as foreign investors cut back on bets for aggressive interest rate hikes. This shift follows Reserve Bank of India measures to stabilize the rupee, signaling a change in market expectations for monetary policy.
The five-year overnight index swap (OIS) market in India saw record-breaking activity on Wednesday, with trading volumes reaching ₹25,300 crore. This figure significantly surpassed the previous day’s turnover of ₹23,600 crore and is nearly triple the average daily volume recorded earlier this year. OIS contracts are financial tools that investors use to hedge against or speculate on future interest rate movements.
Investors Adjust Rate Hike Expectations
The surge in trading was driven by foreign investors and other market participants aggressively unwinding, or closing out, their existing positions. Many had previously built up large bets expecting the Reserve Bank of India (RBI) to implement a series of rapid interest rate hikes to combat inflation and a weakening rupee. As expectations shift, these investors are now reversing those positions.
This change in sentiment is reflected in the five-year OIS rate, which recently touched a four-month low of 6.1%. This level is a notable departure from the peak seen in April 2026, when the rate reached approximately 6.9%. At that time, the market had factored in expectations for interest rate hikes totaling up to 125 basis points.
Impact of RBI Measures on the Rupee
Recent steps taken by the RBI to boost foreign exchange inflows and provide stability to the rupee appear to be cooling expectations for immediate monetary tightening. After the Indian rupee fell to a record low of 96.96 against the U.S. dollar on May 20, 2026, it has since recovered by roughly 1.5%.
While the market is adjusting its outlook, external factors continue to influence the sentiment. Geopolitical tensions and recent statements from U.S. leadership have kept the currency under a degree of pressure, which the market continues to monitor closely. Strategists, including those from global financial institutions like HSBC, have observed that the potential for significant foreign exchange inflows is currently helping to limit the risk of currency volatility pushing swap rates back up.
Investors will now watch for upcoming economic data and further commentary from the Reserve Bank of India to determine if this cooling of rate hike bets will persist or if inflation pressures will force a change in the central bank's stance. The sustainability of the rupee's recovery and the volume of foreign investment inflows remain key factors for the broader credit and bond markets to track in the coming weeks.
