The scary thing is the government bailout of the insurance company AIG. AIG provided insurance for these banks, municipalities etc against this thing happening with these financial instruments. Essentially, with all of these types of financial instruments failing, AIG did the math and realized there could be a run on the insurance companies. AIG did not have the assets to cover all of the policies it was holding. The government had to step if the banks take the losses on these financial instruments or try to re-insure them with other companies, then banks will not lend money to other banks, business, people etc. The cost of insuring or taking the losses would be too much and the flow of money would stop. Moreover, because everything is so intertwined, nobody can really drill down to what exactly makes up these financial instruments or who owns what.
This is a very basic synopsis of what is going on. I would suggest these websites to stay informed:
www.bankrate.com-The best consumer finance website. The have education modules for all of your personal financial needs.
www.thebigmoney.com-Slate.com's new offspring dedicated to finance and economic news and issues.
www.smartmoney.com-This is the Wall Street Journal personal finance website and magazine. Good stuff and very helpful with breaking down the macro to the micro.
www.wsj.com-Still the standard for financial journalism. They cover everything. There is a premium charge for complete access to the site. Hey, I'm an MBA so I have to have it.
www.economist.com-For the world view on the U.S., this magazine is great. Plus you can get information on the world markets.
www.blackenterprise.com-This might be the best written magazine for African-Americans. The website is very informative.
If you really get into this stuff, there are thousands of sources for information. I tend to like ready websites or magazines, rather than watch CNBC or other financial networks. The nature of television doesn't let people digest these issues thoroughly in my opinion. Shout out to Bloomberg media also. There is a reason this guy is a billionaire.
