The Asian Development Bank (ADB) has slashed India's economic growth projection for 2022-23 to 7 per cent from 7.2 per cent earlier, citing higher than expected inflation and monetary tightening.

India's economy grew 13.5 per cent year-on-year in the first quarter of 2022-23, reflecting strong growth in services, ADB said in a supplement to its flagship ADO report on Wednesday.
