* SBI reports loss of $1.13 bln, far beyond analyst estimates
* Gross bad loan ratio rises to 10.91 pct from 10.35 pct in Q3
* Shares jump as much as 6.2 pct (Adds further earnings details, share movement, context)
May 22 (Reuters) - State Bank of India (SBI) reported its deepest-ever quarterly loss on Tuesday, far beyond analyst estimates, as the country’s biggest lender set aside more provisions for bad loans after a change in banking regulation.
Net loss for the three months ended March 31 was 77.18 billion rupees ($1.13 billion), versus an average 12.85 billion rupee loss from 16 analyst estimates complied by Thomson Reuters. The result also compared with a restated net loss of 34.42 billion rupees in the same period a year earlier.
Banks saw soured loans and provisions surge in the quarter after the central bank in February eliminated half a dozen loan restructuring schemes to hasten the clean-up of near-record levels of bad debt. Most state-run banks that have reported quarterly earnings so far have posted losses.
SBI’s bad-loan provisions for the quarter more than doubled from a year earlier to 280.96 billion rupees. Gross bad loans as a percentage of total loans rose to 10.91 percent from 10.35 percent three months earlier and 6.90 percent a year prior, the lender said in a statement.
Net interest income for the quarter fell 5.2 percent to 199.74 billion rupees.
Shares of the lender rose as much as 6.2 percent after the results in a broader Mumbai market that was 0.1 percent higher.
