Where to hold 100K with highest interest?

[Bearded Man]

CD's, REPUTABLE online banks, etc. Right now cash sitting in my account is losing value, and I want to put it into something that at least doesn't cause it to lose value, or minimizes the loss. I actually have more cash I could put in but want to leave some for buffer/emergency fund in case funds are slow to retrieve.

Series I savings bonds? You can only buy $10k worth per year ($15k if you have a big tax refund). The interest rate varies based on inflation, and is currently 1.64%. The big caveat is that you can't withdraw your money for the first year. After that, you can withdraw at any time and the interest rate is much better than any bank will pay these days.

Also look at TIPS via Treasury Direct if you just want to peg to inflation (or deflation). I've parked cash at both Ally and Everbank to get a bit of yield (~1.0% right now). Part of it depends on how long you want to sit on the cash since CDs, TIPS, I-bonds, etc all earn a little more but are more effort to cash in.

As others have noted, it depends on your time frame....

Current inflation is zero. A savings account will give you 1% so it's not really loosing value is it?

That said if your timeframe is longer you can get just over 2% with a 5 year CD. I-bonds will give you 1.64%, pegged to inflation.
