US measures of core inflation fell from February through May. The US reports June CPI at the end of the week. There is a reasonable chance that the core rate stabilizes. However, the movement away from the target has spurred expressions of caution from numerous Fed officials, even though the minutes of the June FOMC meeting showed that most officials recognized transitory factors weighed on prices.  

A careful reading of Fed comments led us to conclude that a consensus on reducing the balance sheet was intact, though a consensus for another hike may prove more difficult until there is more evidence for the official suspicion. Hence we look for the FOMC meeting in a fortnight to only modestly tweak the statement. In September we expect the Fed to announce that it will begin implementing its strategy to gradually reduce its balance sheet starting in October. Depending on the evolution of the economy and inflation, a third rate hike for the year could be delivered in December.  

For the same of this exercise, let’s assume that there is no chance of a hike before December. No chance may exaggerate it a bit, but probably not very much and it makes for a simpler exercise. Fed funds would likely trade around current levels, which is 116 bp on an average effective basis. This is what is averages for the first 12 days of December. On December 12, if the Fed were to hike rates, we should assume that the new effective average would by 25 bp higher or 141 bp.  

That average could last 16 days to Friday, December 29. The effective average rate for the last trading day of the year typically falls post-crisis. Last year it fell by 11 bp. If we assume that the effective rate does the same thing this year, and recognizing that the Dec 29 effective average rate is the same for December 20 and 31, the weekend, Fed funds average 130 bp for the last three days of the month. When you do the math with these points, the outcome is an average of 130.25 bp for the month.
