NEW YORK/LONDON, July 20 (Reuters) - World stocks dropped and Treasuries prices rallied on Tuesday after lower-than-estimated revenue at Goldman Sachs Group Inc <GS.N> and a drop in U.S. housing starts intensified worries the U.S. economic recovery was losing momentum.
Goldman Sachs' earnings slid 82 percent in the second quarter, hampered by its settlement with the U.S. Securities and Exchange Commission and the UK's payroll tax. Profit dropped to $613 million from $3.44 billion, while revenue slid 36 percent to $8.84 billion. For more details see [

"Both the stock and bond markets are telling you that we are in for sluggish growth," said Margaret Patel, the senior portfolio manager at Wells Fargo Funds who oversees both equities and fixed-income assets.
Economic data on housing didn't help the sour sentiment.
U.S. housing starts hit their lowest level in eight months in June, but a rise in building permits offered hope that homebuilding was poised to pick up.
The Commerce Department said on Tuesday housing starts dropped 5.0 percent to a seasonally adjusted annual rate of 549,000 units, the lowest since October. It was the second straight month of declines in groundbreaking activity and was well below market expectations for a 580,000-unit rate.

EURO TAKES A BREATHER
The euro was lower, reversing a climb to its highest against the dollar in more than two months.
It retreated from $1.3029 hit on trading platform EBS as some investors questioned whether the single currency would sustain gains above $1.30, given that bank stress test results due on Friday may reveal weakness in euro zone financial institutions.
The poor demand at Hungary's debt offer also stung the euro as it weighed on risk sentiment.
"We've seen risk appetite claw back a fair amount, and the market is questioning whether that move is valid," said Jane Foley, director of research at Forex.com.
