Public sector banks are more stressed than their private sector counterparts with the former figuring among the top 20 banks with the highest gross non-performing asset (GNPA) ratios, according to CARE Ratings’ analysis of the first quarter results of 38 banks.

IDBI Bank (with gross NPA ratio of 24.11 per cent of gross advances) and Indian Overseas Bank (23.6 per cent) have NPA ratios of over 20 per cent. Among PSBs, Indian Bank has the lowest GNPA ratio of 7.21 per cent, the credit rating agency said.

Eight PSBs banks — IDBI Bank, Indian Overseas Bank, UCO Bank, Bank of Maharashtra, Central Bank of India, Dena Bank, United Bank of India, and Corporation Bank — had a GNPA ratio of over 15 per cent as of June 2017.

YES Bank is the only bank in the sample of 38 banks with a GNPA ratio of less than 1.

State Bank of India (SBI) accounted for the largest share of about 22.7 per cent (or ₹1,88,068 crore) in the total NPAs of 38 banks (aggregating ₹8,29,338 crore) as of June-end 2017.

SBI, Punjab National Bank, Bank of India, IDBI Bank, and Bank of Baroda accounted for 47.4 per cent (totalling ₹3,93,154 crore) in the total NPAs as of June-end 2017.

Among the top 20 banks, according to GNPAs in absolute terms, 18 are PSBs and only two are private sector banks — ICICI Bank and Axis Bank. These two private sector banks have a combined share of 7.9 per cent in total NPAs.

CARE Ratings said in the April-June quarter (Q1) of FY18, NPAs of a sample of 38 banks increased by a sharp 34.2 per cent on a year-on-year basis. Also, the NPA ratio increased to 10.21 per cent in June 2017 from 8.42 per cent in June 2016, which is the highest in the last six quarters.

On a quarter-on-quarter basis, the increase in NPAs has been the highest in Q1 FY18 witnessing an increase of about 16.6 per cent to reach ₹8,29,338 crore as of June 2017.

The agency said the performance of banks with respect to NPAs has not been too positive of late. “While it was largely expected that the NPA ratios would have settled by March 2017, as there were indications of stabilisation relative to December 2017, the picture emerging for Q1 FY18 is that the NPAs have deteriorated further for the system as whole,” it added.
