LONDON, Oct 23 (Reuters) - The dollar and euro rose broadly on Friday benefiting from a steep slide in sterling after data showed the British economy was still mired in recession in the third quarter, confounding expectations for a return to growth.
News the British economy shrank 0.4 percent in the three months to September overshadowed a relatively more positive set of euro zone economic data, knocking sterling off a six-week peak against the dollar.
Sterling tumbled almost three cents against the dollar and the euro jumped more than one percent versus the pound. This kept the dollar's trade-weighted index in positive territory, while the euro also drew support from the euro zone purchasing managers indices and the Ifo index of German business morale.
The UK data shock bolstered talk the Bank of England will extend its quantitative easing programme next month. And coming after relatively dovish statements from the Swedish and Canadian central banks this week, it cast some doubt over the strength and synchronicity of the global recovery.
"No doubt people will continue now to speculate there'll be more QE coming down the pipe in November and all of these things are not sterling positive," said Jeremy Stretch, strategist at Rabobank.
At 1112 GMT, sterling was down 1.4 percent on the day at
$1.6393
The euro was up 1.5 percent on the day at 91.76 pence
This supported the euro's 0.1 percent gains on the dollar to
$1.5042
"The risks continue that we're going to grind higher in euro/dollar and markets will continue to use dips to buy at better levels," Stretch added.
"If the markets believe the Fed are going to be on hold for an indefinite period then obviously it's a case you can utilise the cheap and readily available dollars ... to invest in higher yielding assets elsewhere."
The dollar index, a measure of its value against six major trading partner currencies, was up 0.2 percent on the day at 75.23.
EURO ZONE CHUGS ALONG

Earlier on Friday, euro zone purchasing managers indices and the Ifo index of German business morale showed the bloc's economic recovery to be generally on track.
It was something of a mixed bag, however, with the PMIs well above forecasts but the Ifo numbers not quite as robust as analysts had expected. See [ID:nLN608219] and [ID:nLN230070].
Economists at WestLB said in a note that the German economic recovery will continue in the coming months, but the global economy will be unable to regain its "dynamism" of recent years.
"As a result, our assessment that the coming year will only see a modest economic improvement remains unchanged," they said.
The dollar's trade-weighted gains were also supported by its rise against the yen, which was under broad selling pressure on the back of unfavourable U.S-Japanese yield spread moves and an accumulation of domestic factors.
The country's banking minister said Japan needed a second extra budget worth around 10 trillion yen and expectations grew that government debt would rise and a privatisation scheme be revised, pushing the dollar up to options barriers at 92 yen.
The dollar was last up 0.3 percent at 91.67 yen, having hit its highest in a month earlier in Asia at 91.92 yen.
The spread between 10-year U.S. and Japanese government bond yields widened to 210 basis points in favour of the dollar, making U.S. bonds more attractive to Japanese investors. Earlier this week that yield advantage was 196 basis points.
Later on Friday, Federal Reserve Chairman Ben Bernanke speaks. Traders are also digesting Chicago Fed President Charles Evans' remarks on Thursday that the Fed isn't particularly worried about inflation right now but is monitoring it closely. (Editing by Andy Bruce)
