Based on treasury.gov published rate.

My first try on a # prediction market so hopefully I didn't fudge it up...

To clarify - we are talking about the rate for I-bonds issued in May, not the current rate for bonds issued through April 30th.

This will also include whatever the base rate is for bonds issued in May.

predicted HIGHER

If this was last month the inflation portion of the bond would be 2.71%

If March goes up what Feb did the rate will be 3.84

Those numbers do not count the non-inflation based portion.

predicted HIGHER

@SuperTaxGenius it's going to be over 7%

predicted HIGHER

@MarkIngraham I hope you are right but the math doesn't seem to support it.

What makes you think that it will?

predicted HIGHER

@MarkIngraham Those are the current rates. The question is about the May I-bond rate that will be announced for May based on the March 2023 CPI-U report.

predicted HIGHER

@SuperTaxGenius fed will raise .25% so 7%

predicted HIGHER

@MarkIngraham That is not the I-Bond rate. The I bond rate is the March CPI-U number (not yet announced) minus the September CPI-U number divided by the September CPI-U number times 2 plus a base rate that is usually less than 1.

It is in no way formally linked to the Feds rate though the feds are trying to lower inflation which will lower the I-Bond Rate.

predicted HIGHER

@SuperTaxGenius

So it will be 1% if the cpi is the same?

predicted HIGHER

@MarkIngraham It will be whatever the fixed rate is if inflation is zero (current fixed rate is 0.4% but the May number hasn't been announced.

predicted HIGHER

@SuperTaxGenius so why isn't the April rate 0.4%?

predicted HIGHER

@SuperTaxGenius August 2022 inflation was 8.3%, february 2023 was 6%, 6-8.3=-2, divided by 6 is -.3, times two is -.6, plus .4 is -.2, so April bonds are -.2%?

predicted HIGHER

@MarkIngraham The April rate was set based upon numbers from 6 months ago. CPI-U numbers NOT the published inflation rates.

@SuperTaxGenius OK that's different math, but I still expect a massive fed increase to drive the base rate to 6% or so.

predicted HIGHER

@MarkIngraham as a bond holder...I hope you're right....as a predictor...I believe you are wrong ;)

predicted HIGHER

@SuperTaxGenius base rate is normally increased when fed policy changes, fed is raising faster than ever

predicted HIGHER

@SuperTaxGenius I'm guessing 5 to 6 final rate - but that is also based a bit on hope.

predicted HIGHER

@MarkIngraham I'm expecting a 0.8% base rate

predicted LOWER

Jan CPI-U number, if unchanged until March indicates 1.59% I rate.

Continuing trajectory from Dec to Jan indicates 4.79
