The G8, made up of the world's largest developed economies, meets this week to weigh the greatest risks faced by the financial system in two years.
NEW YORK (CNNMoney) -- The leaders of the world's most powerful economies will confront growing threats to the global economy -- and each other -- at a two-day meeting in France this week.
Questions about the ability of several European nations to pay their debts is only one of the problems facing the leaders of the G8 -- the eight largest developed economies in the world.
Also likely to be discussed is the United States' federal budget deficit and the looming debt ceiling the country is facing, as well as high commodity prices fueling concerns about inflation around the world.
Cap that off with the fact that the International Monetary Fund needs a new boss. Clearly, the group of leaders has a lot to discuss in the meeting, which begins Thursday.
"One of the problems is they have too much to talk about, and not enough time to talk about each one of them," said David Wyss, chief economist for Standard & Poor's.
Here's a quick look at what's at stake:
European sovereign debt: The bailouts of the weaker economies like Greece, Ireland and Portugal seemed to be settled a few months ago. No longer.
There is a growing belief that Greece is going to have to restructure its debt as its economy continues to shrink in the face of stiff austerity measures demanded by lenders.
Greece, Ireland, Portugal and Spain have combined outstanding debt of about $2 trillion and a large proportion of that debt is held by European banks, according to estimates from Desmond Lachman, resident scholar at the American Enterprise Institute
Restructuring would mean extending the length of time Greece has to pay off the bonds, or even forcing lenders to write-off some of the debt.
But officials with the European Central Bank and other stronger economies are strongly opposed to such proposals.
"Restructuring is not a solution, it's a horror story," Christian Noyer, governor of the Bank of France and a member of the ECB board, told reporters Tuesday, according to numerous press reports. He said if Greece fails to meet the terms of its bailout agreed to a year ago, Greek government debt will be "ineligible as collateral" at the ECB, which would spark a European banking crisis.
But protests against the austerity required under the bailout are rising in Greece, and voters in other European countries are also pushing back against the measures. Spain's ruling party lost elections over the weekend.
Jurgen Stark, the ECB's chief economist, recently warned that if a country like Greece defaulted on its sovereign debt, it could trigger a banking crisis worse than what happened after the collapse of Lehman Brothers, as it quickly spreads to countries like Ireland, Portugal and Spain.
U.S. economic policy: The meeting also comes as the United States grapples with its own deficit debates, and Democrats and Republicans wrestle over raising the debt ceiling, which the federal government hit last week. Some fear that if the two sides can't reach an agreement by early August, it could result in a doomsday scenario in which the government cannot pay what it owes.
Also, since the last time the leaders met, Standard & Poor's lowered its outlook for U.S. sovereign debt to negative, meaning it was at risk of a future downgrade.
The U.S. Federal Reserve is also likely to come under fire during the meeting.
In April the ECB became the first central bank among developed economies to raise its benchmark interest rate in response to rising inflation pressures.
There has been much criticism of the Fed's efforts to pump more money into the U.S. economy. Critics charge that the Fed is partly responsible for rising global prices, an argument Fed leadership denies. Still, expect to see more statements that it's time for the Fed to start tightening at the meeting.
IMF leadership: The arrest of Dominique Strauss-Kahn in New York last week has thrust the issue of IMF leadership to the forefront much sooner than expected. Europeans quickly aligned behind the candidacy of French Finance Minister Christine Lagarde as his successor. Traditionally a European has led the global agency charged with rescues of troubled economies and currencies.
But many in the developing world are pushing for a new director from an emerging market, arguing that the post should not automatically go to a European.
American leaders have so far tiptoed around the issue, saying they want to see a quick but open succession process.
