NEW YORK, LONDON, April 29 (Reuters) - The euro rebounded from one-year lows and risk premiums eased on Thursday as Greece readied severe austerity measures to secure a planned aid package that would be bigger than initially thought.
Hopes of a resolution to Greece's debt problems lifted crude oil prices above $85 a barrel while global equities advanced after two days of losses. For details see: [
]Officials from the International Monetary Fund, the European Central Bank and the European Union met with Greek representatives, and sources familiar with the talks said details of a three-year deal would be announced by Monday. [
]News of an expected aid package of up to 135 billion euros ($180 billion) sparked a relief rally across markets that had feared contagion would engulf the euro zone. Debt yield premiums eased and the cost of insuring riskier debt dropped as investors grew more confident a deal was in sight.
Uncertainty over the size and timing of a planned aid package for Greece has weighed on markets for weeks, while concerns of spreading sovereign credit risk gained on Wednesday after Standard & Poor's cut Spain's rating one notch.
Earlier in the week S&P lowered Greece to junk status and downgraded Portugal. [
]"The market seems slightly more comfortable today, with the expectations of an imminent aid package," said Matthew Strauss, a senior currency strategist at RBC Capital Markets in Toronto.
The euro <EUR=> was up 0.1 percent against the dollar to $1.3224 after rising as high as $1.3280 earlier.
Also lifting risk aversion was a report that said euro zone economic sentiment in April was better than expected, which could boost consumer spending and consumption. [
]In the United States, the Federal Reserve's assurance on Wednesday that it would keep interest rates low for an extended period also helped ease risk aversion.
European stocks rose, recovering from the market's worst two-day slide in nearly three months, following a slight easing in Asian equity markets. Wall Street pushed higher.
Positive corporate results continued to raise investors' risk appetite, with Banco Santander up 4 percent after the euro zone's largest bank posted forecast-beating results.
In the United States, profits from Aetna Inc <AET.N> and Visa Inc <V.N> beat expectations but Procter & Gamble Co <PG.N> forecast results below expectations and Exxon Mobil Corp <XOM.N> posted earnings that were below expectations.
"(P&G and Exxon) are certainly market share leaders and important for their industries, but the overwhelming sense of earnings this season has been pretty positive. So I'm not too weighed down on those," said Andy Fitzpatrick, director of investments at Hinsdale Associates in Hinsdale, Illinois.
