If the financial markets resemble a drunken sailor, lurching from one lamppost to the next, there's a reason for it. But you don't want to be the one waking up with a financial hangover.

Everyone's doing it
Amid all the turmoil, even supposedly conservative financial institutions were apparently taking more risk than they should have. Money market fund pioneer Reserve Primary took on more than $750 million in Lehman debt, and when the investment house filed for bankruptcy protection, Reserve was apparently left with no choice but to "break the buck" -- leaving investors with a 3% loss on something they thought could never lose money.

That last-gasp action has calamitous implications, and may feed a run on money market funds in general. Where we had a couple of brushes with buck-breaking last year -- Bank of America (NYSE:BAC), Wachovia (NYSE:WB), and Legg Mason (NYSE:LM) all had to step in to prevent their funds from posting losses -- this was only the second time ever that a fund let its net asset values trade below the sanctified $1-per-share level.

So if you can't trust your investment banker, your insurance broker, or even your supposedly "safe as cash" money fund, then where should you put your cash?

Nice, safe, and comfy
As long as you remember that "safe" equals "low yields," there are still plenty of options open to you.

  • Treasury bills. You can buy Treasury bills from the government itself at TreasuryDirect.gov, or buy money market funds that purchase only Treasuries. Current yields are very close to zero, however, given the flight to quality in recent days.
  • Money market accounts issued by banks. Different from money market funds, bank money market accounts are insured by the FDIC for up to $100,000 and were averaging 2.4% recently, according to Bankrate. You could shop around for a better yield -- Bankrate showed FlagStar Bancorp (NYSE:FBC), for example, offering rates as high as 3.65%.
  • Bank CDs. Certificates of deposit are a good option if you're willing to tie up your money for a few months. A 6-month CD is currently yielding 3.16% on average.
  • And, yes, money market funds. Although Reserve broke the buck and Standard & Poor's put a handful (well, two handfuls) on credit watch, the vast majority of such funds remain a safe place to park your cash. Choosing large, established families of funds like Vanguard or T. Rowe Price (NASDAQ:TROW) ought to serve you well.
