This is in contrast to what happened following the collapse of Lehman Brothers at the peak of the credit crisis last September. Following that shock, clients woke up to the reality of counter-party risk and began to spread their funds across a number of banks - in particular to those with stronger balance sheets.

But now, Mr Mahesh, who is also Deutsche Bank's head of global investment solutions (Asia Pacific), believes clients will begin to differentiate banks based on the quality of their portfolio and risk advisory services.

Increasingly, the conversation has to centre around risk and ways to dampen or hedge it.

“We tell clients to show us their portfolios, and they are doing that, even if the money is sitting in other banks,” he was quoted as saying.

“If a client thinks, here is a bank that can save me money when things are choppy, he is willing to listen. You change the paradigm of private banking. Our share of wallet has increased dramatically because of this.”

The re-pricing of risk has opened up opportunities for clients. “If you're an investor and the return you can get per unit of risk is higher, that's a great thing,” said Mr Mahesh. “We see that happening now. We think that's the single most significant positive development for buy-side investors,” Mr Mahesh is reported to have said.
