As someone whose generation was brought up on the virtue of thrift, Rajiv's father did not understand the culture of unfettered consumerism that has been one of the engines of India's stunning economic growth.

If Rajiv couldn't pay up front for a purchase, he used his card, until he exhausted his credit limit about six months ago.

"The outstanding is so high now that I am hardly able to pay the minimum due," said the 26-year-old, once the quintessential ambitious customer every bank targeted, hoping the offer of a credit card or loan for that dream car would prove irresistible.

With India's growth, an average of 8.6 per cent in the last four years, matched only by an expansive embrace of debt-fuelled consumerism among its growing middle-class, the country was a magnet for retail lenders.

But now as the global slowdown hobbles India's growth, while interest rates are still high, banks, companies and consumers are feeling the strain of rising debt.

According to latest central bank data, consumer credit growth in August slowed to 17.4 per cent from 21.4 per cent a year ago.

Housing loan growth slowed to 13.9 per cent in August from 17 per cent last year, while advances for consumer durables fell by 7.9 per cent from a year ago.

Car sales, a major indicator of the economy's health, fell an annual 6.6 per cent in October, the third decline in four months.

"There has been significant moderation in retail credit disbursal," Abheek Barua, chief economist of HDFC Bank, India's second largest private bank, said.

"Consumer credit has fallen in the past 6-7 months because of very high rates and with banks becoming more careful about any spike in non-performing assets."

PAYING FOR PAST EXCESS

Just a year ago things were very different.

According to Goldman Sachs, Indian consumers' growing appetite for cars, computers or clothes during the past eight years accounted for nearly as much growth in global demand as the United States, and triggered huge demand for credit.

Total loans, including mortgages and unsecured loans such as credit cards, grew around 30 per cent annually in the last three years, an expansion the central bank called "unprecedented".

But now the strain of the global slowdown is reflected in most banks raising their loan-loss provision, while overextended Indians find themselves in the whirl of revolving credit.

The largest among Indian private banks, ICICI, a major player in consumer credit markets, raised its bad loans provision to 1.91 per cent of net advances from 1.43 per cent a year ago. Retail credit is the biggest contributor to its bad loans.

According to ratings agency Crisil, a unit of Standard & Poor's, Indian banks' consumer loans are now likely to be major risk areas as bad debts are expected to rise to four per cent of advances by 2009.

Outstanding loans on credit cards stood at about $6 billion at the end of August, up a staggering 86 per cent from a year ago.

NO CHECKS, LITTLE SECURITY

Until about two decades ago a father would raise a loan from friends and family or take an advance from his retirement benefits to marry off a daughter or buy a house.

But as the economy opened up, credit providers distributed loans indiscriminately with little care for the credit-worthiness of the debtors – it became common to be accosted by credit card agents or offered a loan with virtually no demand for a security. "If you produce your plane boarding pass, you might be able to obtain a credit card as you exit the airport terminal," Manmohan Agrawal, executive director of Axis Bank, said in a Wharton School business report last year.

Defaults were bound to follow. Consumer credit repayments three months or more overdue form about 7-9 per cent of total loans outstanding this year, and, Crisil says, could touch 15 per cent.

India has about 30 million credit cardholders, a number that has tripled over the past five years as private and foreign banks chose plastic to break into the Indian market.

Indians put $14 billion on their cards in fiscal 2008, more than three times the amount charged four years earlier.

Last month, police broke open the door of a Mumbai apartment and recovered the bodies of AK Nair – both had swallowed poison – and their two dead children.

Police found 73 credit cards in the house.
