Subject: OT: T-bills
Well off topic, but I imagine I'm not the only one with a wee cash balance at the moment.
I use Interactive Brokers, and I've been buying T-bills.

They sent me a remarkably helpful message this morning. Never pass up a free lunch.

Your account U**** holds USD [xxx] of US Treasuries maturing on 02/20/2025.
If you plan to replace your position on Maturity Date, you may forego one (1) or more days of interest yield, estimated at USD [12.19 per million], due to US Treasury trades settling on the next business day.*
You may use your current US Treasury buying power of USD [xxx] to replace that amount of your position one (1) business day before maturity, 02/19/2025. Buying new US Treasuries on 02/19/2025 will enable you to start earning interest day(s) earlier, on 02/20/2025 instead of 02/21/2025.

You are being notified of your buying power (excess margin capacity) as a courtesy. Your account will not incur any additional fees as a result of purchasing on 02/19/2025.
Please find additional information regarding US Treasuries here: How Can I Trade US Treasuries?
