The G-20 last weekend committed to exercising strong oversight of credit rating agencies. Many of the financial instruments that are at the heart of the financial crisis had been given AAA ratings, meaning they were supposed to be of the highest quality. That turned out to be wrong. Will the G-20 declaration change anything?

Stock prices are at six-year lows. Over the past two days, the Dow Jones industrial average has lost more than 6 percent of its value. The $700 billion bailout was supposed to stabilize the financial industry and get banks lending again. But that hasn't happened yet.

Oil prices dipped below $50 a barrel Thursday. That's a nearly two-thirds drop from the record high of more than $147 in July. While that may sound like pleasant news, the low price is actually a symptom of a weak economy. Since many expect the economy to drag for a year or more, oil prices likely will stay low.

The financial crisis is closing in on Citigroup. The banking colossus has more than 200 million customers around the world. But investors are increasingly worried about Citigroup's financial condition. Its share price tumbled more than 25 percent Thursday.

Citigroup lost half its value this week and is trading at levels not seen since the mid-1990s.

Some would-be investors may be too scared to dip their toe into the investment world of stocks and bonds. Now they don't have to worry, and can take the plunge in fantasy investing.

Lawmakers are demanding that GM, Ford and Chrysler submit a plan for improvements before Congress will consider a $25 billion aid package for the auto industry. House Speaker Nancy Pelosi and Senate Majority Leader Harry Reid say if there's a viable plan, Congress might return to work early next month for a vote. Some lawmakers wanted Congress to stay in session.

Senate Banking Committee Chairman Christopher Dodd says he's angry that banks are using government-provided funds to pay dividends, for excessive executive compensation and for acquiring other banks. He also says the Treasury has been too slow in addressing the mortgage crisis.

After the Big Three auto executives spent two days seeking support on Capitol Hill for a bailout, the grand finale is no finale at all. Democratic leaders say they are delaying a vote until the auto companies present a plan showing how they will restructure their business.

Amid job cuts, restructuring and pleas to Congress for financial aid, General Motors and Chrysler are represented, but not making much of a splash, at this week's Los Angeles Auto Show.

As central banks continue to slash interest rates almost to zero, prices can plummet. It creates a liquidity trap, as it did in the 1930s and in Japan during the 1990s. Harvard economist Kenneth Rogoff outlines what deflation could mean for modern America.
