MUMBAI, June 4 (Reuters) - Overseas investors are opting for short-term Indian government bonds as they find attractive entry points amid ‌expectations of the interest rates cycle turning, with the Iran war driving ‌inflation higher.

Bonds with maturities of less than five years made up over two-thirds of the ​top 10 notes foreign investors bought during March-May, higher than less than half of similar purchases in January-February, clearing house data showed.

Overseas investors overall bought bonds worth 221 billion rupees in January-February, while in March, they sold a record 177 billion ‌rupees, before turning buyers in ⁠April-May.

Indian government bond yields have risen over the last three months, with shorter duration yields - most sensitive to rates - spiking ⁠on inflation concerns due to the Iran war-linked energy shock.

The 10-year benchmark bond yield rose 34 basis points from March to May, while the five-year yield rose ​55 bps, ​with the spread dropping to an eight-month ​low of 15 bps.

Investors are ‌increasingly factoring a shift toward tighter policy, said Krishna Bhimavarapu, APAC economist at State Street Investment Management. While the Reserve Bank of India is widely expected to hold rates at the June meeting, the policy direction is clearly shifting, he said.

"In such an environment, the front end (of the yield curve) offers more ‌attractive risk-adjusted carry with lower duration risk, while ​the long end remains vulnerable to further ​repricing if the tightening cycle materialises."

The ​RBI rate decision is due on Friday, with most economists ‌expecting status quo, while Standard Chartered ​Bank has called ​for a 25-bp hike.

"The curve has bear flattened with short-end yields rising more than the long-end yields. This has created a valuations-driven opportunity for ​foreign investors to buy ‌short-end bonds, Nagaraj Kulkarni, chief rates strategist - South Asia & Indonesia and ​head - flows strategy at the foreign bank, said.
