Soaked in bad news, GM and Ford received yet another dousing when their three big European credit insurers dropped them this week. Euler Hermes, Atradius, and Coface have all refused to write policies for suppliers trading with both automakers. The three giant insurance companies control more than 80 percent of the world's credit insurance (insurance companies typically pull their coverage when a client stops proving insurers with enough information to calculate a credit risk, or their overall risk profile has deteriorated). Without their credit cover, suppliers will be forced to either trade uninsured, cease trading, or ask for payment up front. Supply issues aside, this news only compounds the automaker's problems as it also weakens investor confidence, already completely slumped.

After announcing earlier this week that GMAC would only finance customers who hold credit scores higher than 700, General Motors has decided it would be prudent to reassure consumers that they are still in the business of securing loans and selling vehicles. Starting Friday, GM will launch a "Financing That Fits" campaign on a national level. Through advertising on television, newspaper, radio, and the Internet, GM will promote dealer financing with GMAC Financial Services and, for the first time, with other lenders. To further restore consumer confidence, the ads are also designed to promote the experience and expertise of the dealership professionals who work in finance and insurance.

The auto industry is in a bad sales slump, and while trucks and SUVs are being hurt particularly by fuel prices, the rest of the market has an even bigger problem. The tight credit market is making it much harder for dealers to sell you transportation, and the problem isn't relegated to just those with poor credit. Banks want higher cash-to-debt ratios, larger down payments, and then they're still charging higher interest rates on top of all that. GM's Mark LaNeve estimates his company is losing between 10,000 and 12,000 sales per month due to the credit crunch, which is close to a full point of market share.

Cerberus Capital Management shot off a nine-page letter to investors outlining ways that Chrysler could sink, while also pointing out that they believe Chrysler's on the track for success. Some of the possible failure scenarios include a nasty recession, an extreme slowdown in the car market, or a further credit downturn.
