Stock markets in Europe and Asia perked up Monday after a weekend meeting of the leaders of France and Germany provided a promise of action on Europe's debt crisis.
Oil prices rose above $84 a barrel while the dollar slipped against the euro and the yen.
German Chancellor Angela Merkel and French President Nicolas Sarkozy on Sunday said a comprehensive response to the debt crisis would be finalized by the end of the month, including a detailed plan to ensure European banks have adequate capital. Stock markets welcomed the announcement, even though it offered little in the way of specifics.
In midday European trading, Britain's FTSE 100 rose 1 percent to 5,353.84. Germany's DAX gained 0.4 percent to 5,699 and France's CAC-40 climbed 0.9 percent to 3,124.5. Wall Street was poised for a higher opening, with Dow Jones industrial futures up 0.9 percent at 11,166 and S&P 500 futures rising 1 percent to 1,166.

Investors eyed banking stocks after a move by the Belgian government to buy the national subsidiary of embattled bank Dexia for euro4 billion ($5.4 billion) and provide tens of billions of euros in new guarantees as part of a wider bailout of the lender, the first banking victim of a new squeeze in European credit markets.
The part-nationalization of Franco-Belgian Dexia was triggered by other banks' increasing reluctance to lend to it due to its exposure to highly indebted eurozone states like Greece and Italy and to struggling municipalities in the United States.
On top of the nationalization, the governments of Belgium, France and Luxembourg together will provide an additional euro90 billion ($121 billion) in funding guarantees for the bank for up to 10 years.
Investors were treading carefully as Greece continued to struggle with its finances to qualify for the next installment of an international bailout loan needed to avoid bankruptcy. A Greek government default would cause the value of Greek bonds held by European and U.S. banks to plunge in value with possible global repercussions.
"After so many months, it still is not clear how leaders are going to resolve" the European debt crisis, said Lee Kok Joo, head of research at Phillip Securities in Singapore. "I think a lot of investors are just waiting to see what the next step is that some of these leaders will take."
Analysts have urged European officials to identify all the banks in the region that need to replenish their capital reserves, then decide whether to compel them to raise that money from markets and to provide government financing to the ones that can't.
Many experts say the capital cushions of many European banks must be strengthened in order to withstand a Greek default.
"Discussions over the weekend between German Chancellor Merkel and French President Sarkozy delivered little in substance," Credit Agricole CIB said in a research note.
