Washington Mutual  sent me an email today indicating that they will be increasing their high yield savings rate from 3.75% APY to 4.00% (at midnight tonight, if you read this on Monday), which will beat all the banks on my list of best online savings accounts  by at least half a percent (FNBO Direct is second with a 3.50% APY interest rate).
Nothing else will change about either the Free Checking or the Savings account offer, you can read my brief WaMu review  to learn more about the accounts.
There have been concerns lately that WaMu was facing some liquidity concerns (mostly in the chaos that was last week, but the FDIC did send a MOU ) but they are FDIC insured up to the same $100,000 as every other insured bank. WaMu benefits from the fact that its short term financing can come from deposits , rather than short term borrowing, so it’s not as exposed as investment banks. If the liquidity issue still concerns you and you don’t trust that FDIC will make you whole (it will), your next best option is FNBO Direct with a 3.50% APY rate or opening a CD somewhere else. I haven’t read a single thing about them having problems and they too are FDIC insured.
