Highlights Move comes in the wake of a more than $2 billion fraud at PNB

The Goldman warning is a blow for the government

Investment bank Goldman Sachs downgraded its forecasts for India's economy on Tuesday in the wake of a more than $2 billion fraud at Punjab National Bank (PNB), warning it could spark tighter regulation of the banking sector that would constrain credit growth.In a note to clients, Goldman Sachs lowered its real gross domestic product (GDP) forecast on India for the year to March 2019 to 7.6 per cent from 8 per cent earlier.Last month's disclosure of the fraud by PNB, the second-largest state-run lender has sent bank shares tumbling.The case, along with a flurry of smaller loan frauds since reported by other banks, has sparked new concerns that credit growth is unlikely to pick up quickly in an economy where state-run lenders that account for two-thirds of banking assets are already saddled with a mountain of bad debt.The Goldman warning is a blow for the government, which had hoped that a $32 billion, two-year, bank recapitalisation programme it unveiled last year would help banks to begin to restart lending, spurring elusive job growth in the economy.State-run lenders account for the bulk of the close to $150 billion of soured debt in India. They have already seen the amounts they must set aside to cover bad debts grow due to new central bank rules, and are staring at further loan losses as they pursue a host of defaulters through the bankruptcy court.Goldman said it feared a regulatory crackdown after the huge PNB fraud, and the mountain of soured debt, could increase banks' provisioning burden and so slow credit growth."Markets and investors are questioning whether the problem is more systemic," Goldman analysts wrote in the note, referring to the PNB fraud, adding that markets feared the fraud would likely offset some of the positive effects of the bank recapitalisation and hit overall credit, investment and GDP growth.India regained its status as the world's fastest growing major economy in the October-December quarter, as it grew 7.2 per cent, its fastest in five quarters.Goldman, which forecasts the economy to grow 6.6 per cent in the current fiscal year which ends in March, said it retained its 2019/20 growth forecast at 8.3 per cent.Goldman said its analysts believe PNB was likely to take the hit of the entire $2 billion, wiping off more than a quarter of its net worth.It also said the average haircuts on impaired loans banks would need to take could be 60-65 per cent over the next two years, higher than the 50 per cent it had assumed earlier, meaning overall provisions would rise.The still unravelling PNB fraud, the biggest in the banking history, has prompted the government to ask banks to scan all their bad loans above 50 crore ($7.7 million) for any sign of wrongdoing.Other small cases of fraud have come to light in the past month, while investigations into ongoing cases have picked up pace.
