A new financial crisis will develop from the failure to effectively regulate derivatives and the extra global liquidity from stimulus spending, Templeton Asset Management Ltd's Mark Mobius said.

"Political pressure from investment banks and all the people that make money in derivatives" will prevent adequate regulation, said Mobius, who oversees $25 billion as executive chairman of Templeton in Singapore. "Definitely we're going to have another crisis coming down," he said in a phone interview from Istanbul.

Derivatives contributed to almost $1.5 trillion in writedowns and losses at the world's biggest banks, brokers and insurers since the start of 2007, according to data compiled by Bloomberg. Global share markets lost almost half their value last year, shedding $28.7 trillion as investors became risk averse amid a global recession.
