Capital One: 11-Month 360 CD EXPIRED

So I started to ladder T-Bills for the reasons everyone is stating in this thread. The rate is so volatile (in a good way) that locking into anything even 12 months is too long for me and rates continue to climb. I use fidelity and my suggestion is this.

When they offer the new 4 week and 8 week and 13 week t-bill (they auction on diff days and diff weeks) go in and buy one of each of them with whatever money you can spare. Let's use 5k for each.

I would buy a 4 week t-bill with NO Rollover for 5k
I would buy an 8 week t-bill with NO Rollover for 5k
I would buy a 13 week t-bill WITH Rollover for 5k

Then after 4 weeks when that first on comes up, buy another 13 week t-bill with the 5k WITH Rollover.
Then after 8 weeks when the second comes up, buy another 13 week t-bill with the 5k WITH Rollover.

Now you will have 3 13 week t-bills rolling every 4 weeks or so and rolling into a new one with the proceeds. This way every 4 weeks you are capturing an increasing rate and not locked into anything longer than 13 weeks. You benefit from the rate hikes, can cash out at any time, and you have state tax shelter from the earned interest.

I can almost guarantee that the above will yield you more net income (taking in tax break) at the end of 11months then the 5% locked CD

just my 2cents

You can buy treasuries from just about any brokerage. I use Fidelity, as I like their platform and they don't charge fees/commissions for treasuries.

Follow the above link and scroll down to the row "U.S. Treasury." Choose the duration you want and click on it. You can then click "buy" to start a trade of a specific treasury bill/bond.

This is true, but it doesn't make an 11-month CD at 5% a bad idea. Those HYS can change their rates at any time, but here you're guaranteed to get 5%.
