It was moving in a close range of 77.59 to 77.61 in early deals.
In the previous session, the rupee settled at 77.61 against the American currency.

According to a British brokerage, the Reserve Bank will opt for a larger, 0.50 percent, hike in key rates at its next monetary policy review in June to protect medium-term economic stability in face of the uncomfortable inflation situation.

Meanwhile, Moody's Investors Service on Thursday slashed India's economic growth projection to 8.8 percent for 2022 from 9.1 percent earlier, citing high inflation.
In its update to Global Macro Outlook 2022-23, Moody's said high-frequency data suggest that the growth momentum from December quarter 2021 carried through into the first four months this year.
