The banks’ advance-to-deposit ratio (ADR) remained at 39.3 per cent last month — much below the red line of 50pc, which attracts a 15pc incremental tax. The latest data shows that the ADR increased by 90 basis points month-on-month, but fell by 579bps year-on-year to 39.3pc. The government imposed a 15pc tax in the budget for the current fiscal year on all banks whose ADR was below 50pc.
