Are you really comparing Tesla puts to ibonds? I’m talking about a safe place to put money I will need in the medium term.

I guess I misunderstood you. We know the next 6 month rate is going to be around 6.48%. I consider 9.62% really good and 6.48% good as well. That averages out to a little over 8% over the year. Let's say I hold 15 months to take into account the 3 month penalty, I'm getting that rate (minus federal taxes). And even if I don't, it's beating any other guaranteed investment.

I…don’t think you understand how ibonds work. You get 6 months of the current rate from date of purchase and then 6 months of the next rate. Since I bought this month I’ll get 6 months of 9.62% and then in May I’ll get 6.48% for 6 months. You only have to hold for a year after which point if HYSA is higher I’ll gladly take the 3 month penalty, move it there, and still come out way ahead of any savings account.

I’m not buying them as a long term investment, I’m literally putting property downpayment money there since I’m not yet ready to buy.

Cool, so where do you suggest I put my house downpayment savings that I’ll need in 1-5 years for a higher guaranteed rate?
