Optimizing one's savings rates always seemed to me to be high effort, low reward. Like coupon clipping or credit card churning. You either live with convenience and low returns or you get a slightly better return by making "opening new accounts" your entire life.<p>I already have a credit union account for checking, multiple brokerages, an HSA account, a 401(k) account (different from my brokerages), a Roth IRA account, a 529 account, an account at TreasuryDirect, and probably others I'm not thinking of. Now if I want the best yield savings, I need to open yet another bank account? If I want the best CD rates, I'll need further another account? Yuck!<p>And when I want to move funds from one asset class to another, it's a ACH transfer or some other needlessly multi-day transfer from one institution to another. It's exhausting.
