US banking giant JP Morgan Chase said it had more than doubled profits in 2009 - but sounded caution over rising bad debts amid a fragile economic recovery.
The figures revealed bumper pay, bonuses and benefits across the bank as a whole, which rose 18% to 26.9 billion US dollars (£16.5 billion) during the year.
JP Morgan - one of the strongest performers in the crisis - posted net income of 11.7 billion dollars (£7.2 billion), up from 5.6 billion dollars (£3.4 billion) in 2008.
The performance comes a day after President Obama launched plans to claw back 90 billion dollars (£55 billion) for the US taxpayers over 10 years in return for support given during the financial crisis.
But chief executive Jamie Dimon said he remained "cautious" over the "uncertainties that lie ahead".
"While we are seeing some stability in delinquencies, consumer credit costs remain high, and weak employment and home prices persist," he said.
JP Morgan's bad debt provisions for the year jumped 53% to 32 billion dollars (£19.7 billion) - sending jitters through stock markets worried about recovery prospects.
David Jones, chief strategist at IG Index, said: "JP Morgan showed a more than fourfold increase in quarterly earnings compared to a year ago but a tough time for its retail arm seems to have soured sentiment."
JP Morgan, which has about 15,000 staff in the UK, swallowed up failed rivals Bear Stearns and Washington Mutual in 2008 - helping push revenues to a record 108.6 billion US dollars (£66.7 billion).
Its investment banking division generated almost two-thirds of its overall profits as the company benefited from stock market rallies and fundraising by major companies and Governments.
