I think year over year CPI is about 3.5% right now.
Thus it seems likely to me that I-bonds will yield
at least 4.5% at the next adjustment. Real rates
have been creeping up a little the past week also
so there is a chance that the real rate of 1% could
go up a tad.
It seems to me that you could buy I-bonds, hold
them until the increase in real rates makes it
worthwhile to upgrade. You would only forfeit
3 months of interest if held for 1 to 5 years and
nothing if held more than 5 years. Three months
interest on a base of the current 3.67% would be
about 0.92% giving you a yield of about 2.75%.
for 1 year. That's what ING is paying for a 1 year
CD last time I looked. IMHO, TIPS might beat
PFCU 5.25% over the next 5 years and could do
significantly better if inflation takes off.
Of course TH and Martha are talking about investing
more than the $120k max per couple in 1 year so
this might not solve their problem.
Let me know if this does not compute.
