Under the deal agreed by civil servants and their union, next year's pay settlement will be RPIX minus 1%.
Public sector workers agreed a three year deal which this year equated to a 7% pay rise.
But that dips to 5.8% from January 2024, which is RPIX in June 2023 minus 1%.
RPIX is the inflation rate minus mortgage payments.
Yesterday's inflation bulletin showed the other main inflation indicator, RPI, was running at 7.2%.
That's down 1% on the March figure and shows that prices within the 'basket' that determine inflation are still rising, but not as much as they were.
