Just thought I'd pass along a recent experience chasing after highest yield on cash accounts for my monthly retirement paycheck. Last July based on a postal mail ad for HYSA and subsequent google search I opened a High Yield Savings Account called "Accelerate Savings" with citiBank. It has been a nightmare and I'm in the slow process of closing the account as we speak. Although my problems with the account may not apply to everyone, you should at least be aware of the limitations they impose on you getting your money back out when you need it. First, there is a $15,000/month limit on transfers to other institutions, and $10,000 per transaction and/or per day. The clock resets each time you make a transfer so it is hard to use up the entire $15,000 every month. I've found it impossible to set a monthly check for $10,000 due to previously staggered withdrawals unless I skip a month all together and start over. When I tried to close the account out today on the phone I was told they can't do it over the phone, I have to use their mobile app or website. AND I can only withdraw $50,000 maximum every 24 hours and each withdrawal carries a $30 fee! They make it not only difficult but expensive to take your own money out and use it. Bottom line, ask lots of questions based on your planned usage before you make a deposit in a HYSA from citiBank. This would be a real shocker if planned for an emergency account and a sizeable amount was needed. Other institutions may charge in a similar fashion but I can't say from experience. I'm moving the money as fast as I can to my Fidelity Brokerage Account and taking the small hit on interest rate. They have no limits on frequency or amounts. Lesson learned the hard way!
