NEW YORK, March 16 (Reuters) - The euro hit a five-week high against the U.S. dollar on Monday as U.S. and European stocks rallied for a fifth straight session, signaling investors' willingness to take on more risk.
A rise in euro zone inflation last month also helped push the euro above $1.30 for the first time since Feb. 10. A pledge by the Group of 20 finance ministers during the weekend to double the resources for helping emerging markets lifted spirits as well.
European share indexes closed higher and Wall Street also rallied, led by financial shares after recent comments from some major banks that they had achieved strong starts to 2009.
"The continuation of a broader positive sentiment at the start of the week is helping the euro," said Matthew Strauss, a senior currency strategist at RBC Capital Markets in Toronto. "But the jury is still out on whether we are seeing a dead cat bounce or if the rally in the euro is sustainable."
In afternoon trading in New York, the euro was up 0.7 percent at $1.3013 <EUR=> after earlier hitting a $1.3070 session peak. Sterling gained 0.7 percent to $1.4104 <GBP=>, raising in tandem with UK shares.
The dollar was 0.3 percent higher at 98.14 yen <JPY=>, partly on demand from Japanese importers, though exporters' selling capped dollar gains, traders said.
The greenback has rallied in recent months because investors see it as the safest store of value at a time when economies across the globe are contracting. Its role as a main funding currency outside Europe also enhances its appeal.
When sentiment improves, though, investors feel more confident buying stocks and other currencies, while pressure to hoard dollars for funding needs eases.
FED WATCH
The dollar also was pressured after Treasury said foreigners sold a record net $148.9 billion of U.S. securities in January, stoking concern about the U.S. ability to finance its current account deficit.
There were signs of more weakness in the economy as well. The New York Federal Reserve's manufacturing index fell to yet another record low in March while U.S. industrial production tumbled in February. And in a taped U.S. television interview, Fed Chairman Ben Bernanke said the recession could last most of the year.
"The data this morning does not paint a particularly pretty picture," said Bank of New York-Mellon strategist Michael Woolfolk. "There are really no signs of life in the manufacturing sector of this economy just now, but today, sentiment is trumping fundamentals."
The Fed holds a policy meeting this week and markets are waiting to see if it signals plans to buy long-dated Treasuries in an attempt to keep interest rates low.
Britain's central bank has already bought gilts and the Swiss National Bank intervened in currency markets last week to weaken the Swiss franc to stave off deflation, a move analysts say could be repeated.
The euro hit a 12-week high of 1.5447 francs on Monday and was last up 0.4 percent at 1.5394 francs <EURCHF=>.
The Bank of Japan, which also meets this week, may boost long-dated government bond purchases and is considering buying banks' subordinated debt, according to Japan's Nikkei business newspaper.
