Of course, there's hard-headed pragmatism at work here. For one, retail customers still provide banks with the cheapest source of money. For another, as Ashoke Dutt, head, global consumer bank, Citibank, says, "banks worldwide are moving away from the high-risk high-reward areas, out of the boom and bust cycles". Consumer banks in the US enjoy healthy price-earning ratios of 10-12 per cent, credit card banks get 15-16 per cent and consumer fin-ance companies, 20-24 per cent. The third factor is domestic. The inter-bank call money market, where interest rates rule steep, is no longer as lucrative. And corporates, the traditional clients of foreign banks, have drifted to cheaper modes of raising funds. Says Ramesh Sut-hoo of ANZ Grindlays: "The thrust in retail banking has to be seen in the context of the banker's role being eliminated as the middleman between corporates and the money market as well as foreign banks looking at expansion in consumer markets in the emerging economies." Banks have realised that survival lies in a strong retail asset base.
