Credit Suisse has cut its earnings estimates for corporate lenders by 5-10% owing to an upward revision of corporate impairment & provisioning estimates. However, it has factored in potential gains from stake sales in subsidiaries (general insurance) for ICICI Bank and State Bank of India (SBI), resulting in lower earnings cuts.It said that in addition to the 9.5% gross NPAs, Indian banks have 4-8% of loans parked in various stress classifications (restructured/ SDR but standard) and as most of these forbearances expire over the next 12-18 months, it will keep corporate NPA addition elevated.
