Former Federal Reserve Chairman Paul Volcker said he's concerned that the euro area may break up after the Greek fiscal crisis that sparked an unprecedented bailout by the region's members.

The Portuguese government Thursday followed Spain's lead in agreeing with the main opposition party on more austerity measures to cut the deficit faster than planned, to 4.6 percent of gross domestic product next year from 9.4 percent last year.

After a nearly $1 trillion rescue package meant to end Europe's debt crisis once and for all, financial markets took a second look Friday and began to worry about how the plan would actually work and the implications of the drastic austerity measures for the fragile European economies.

Trading derivatives on regulated exchanges would be a major step forward, but it may no longer be enough. Economic bubbles are not recognized by those inside of them, the Congress of the united States being no exception. The $604.6 trillion derivatives bubble, which is equal to more than ten times world GDP, is a global issue. If existing OTC derivatives remain in place and there are no restrictions on what banks can trade derivatives, there is no actual or immediate reduction of systemic risk. Thus, the risks that led to the financial crisis in 2008 are likely to remain present in the global financial system for years to come. In fact, many banks have more CDS risk now than in 2008. Passing a bank-approved version of the financial reform bill, while it may be portrayed as a political victory or serve to calm financial markets temporarily, is unlikely to prevent another global financial crisis.

Spain's PM has outlined a plan to tackle the country's budget crisis, amid concerns that problems afflicting Greece may spread across the eurozone.

The country's largest banks and trade groups have hired more than 240 former government officials and legislative staffers to lobby on their behalf in Congress, part of a broader campaign by Wall Street firms to limit the impact of proposed reforms on their industry, according to a report issued Tuesday by liberal groups.

Germany's cabinet has passed a draft law to provide for its portion of Europe's 750 billion euro package to prop up the ailing currency. But will the fund work? Experts are warning that the side effects may be difficult to stomach.

The euro has been rescued for the moment, but European politicians have thrown the foundations of Europe's common currency overboard with their unprecedented bailout package. In the longer term, the dangers of the crisis can only increase, and the flood of billions of euros could also lead to inflation

As China gains dominance on the world stage, more and more multinational corporations will need to rethink their assumptions about competing under its state-capitalism model-one in which the government is the principal economic driver. So says Ian Bremmer, president of the political-risk consulting firm Eurasia Group and author of the upcoming book The End of the Free Market: Who Wins the War Between States and Corporations? In this video interview, Bremmer discusses the fundamental distinctions between state capitalism and free-market economies, as well as the strategic implications this has for Western companies and governments alike.

The International Monetary Fund and the European Union are coming to Greece's aid with a financial commitment worth billions. But is it already too late to rescue the cash-strapped country?

Like the giant financial bailout announced by the United States in 2008, the sweeping rescue package announced by Europe eased fears of a market collapse but left a big question: will it work long term? And as details crystallized of the package's main component - a promise by the European Union's member states to back 440 billion euros, or $560 billion, in new loans to bail out European economies - the wisdom of solving a debt crisis by taking on more debt was challenged by some analysts.

The United States officials began talking to their counterparts about an American concept: overwhelming force. "It's all about psychology," said the senior official. "You have to convince people that the government will get its act together."

Meanwhile, the banks that caused much of this mess are getting all their money back. A more equitable approach would require the banks to pay at least part of the bill - writing down the debts of some European governments or extending their maturities into the future to allow battered European economies time to recover.

At a defining moment for the European Union, its largest country, Germany, appeared divided and its leader absent, raising significant concerns about what kind of leadership Chancellor Angela Merkel can offer as the region tries to stabilize financial markets and shore up its common currency.

First came the real estate crisis. Then the financial system melted down. And now, skyrocketing public debt is threatening entire countries. Star economist Nouriel Roubini tells SPIEGEL that more crises will come and go before world leaders agree on true reform. He says breaking up huge banks would be a good place to start.

Europe has put up 750 billion euros in an effort to stop speculation against the European common currency. Still, it remains to be seen if financial markets will learn their lesson. After all, speculators aren't even being punished for the damage they have caused. But they should be.

Chancellor Angela Merkel's ruling coalition was seriously weakened last night after her party suffered a humiliating defeat in a key regional state election which was certain to deprive her government of its crucial working majority in Germany's upper house of parliament.

The EU faced the biggest test in its history last night as it launched a last-ditch effort to save the euro, amid acute fears that markets could unleash a fresh attack on the currency on Monday.

European Union leaders are working around the clock to create a new measure to defend the euro before financial markets reopen on Monday. EU finance ministers will meet on Sunday to discuss the plan.

The fear that began in Athens, raced through Europe, and finally shook the stock market in the United States is now affecting the broader global economy, from the ability of Asian corporations to raise money to the outlook for money-market funds where American savers park their cash.
