Historical CPI-U Linked Rates
Consumer Price Index for all Urban Consumers (CPI-U)
is the measurement of inflation that the Fed uses to determine the variable rate
of the I Bond's total rate. This is also called the inflation rate of the bond.
The CPI-U value is released monthly, but the I Bond rate is only adjusted semiannually
in May and November. I Bonds purchased in November through April use the CPI-U change
from March to September. I Bonds purchased between May and October use the CPI-U
change from September of the previous year through March.
