The CBO released an updated Economic Outlook yesterday. Projected PCE inflation is higher, as are budget deficits. First drop in Fed funds rate in 2025Q1. For me, the most interesting are the GDP projections, including with respect to potential GDP.

Here’s the GDP projection as of June, and as of February.

The CBO projections are based on data available as of May 2nd. The latest CBO projection is substantially above the February projection (see discussion here), largely due to the intervening upside GDP surprises. It’s currently in line with the FT-Booth June median forecast, and the slightly below (for Q2) the Atlanta Fed nowcast. (It’s slightly above the May median Survey of Professional Forecasters estimate).

While the revised q/q growth rate projections are higher in the short term, relative to February forecast (based on data available as of January 6), then decelerate to slower rates by end 2025, implying reversion to potential. That being said, the current implicit CBO projection of the output gap is dramatically different than reported in the February Economic Outlook. [Update: As suggested by Paweł Skrzypczyński, the implied output gap is even larger using SEP and CBO potential. However, we don’t know what the FOMC’s view on potential GDP is, although the Green Book must have an estimate.]

This means the CBO is projecting a positive output gap for the next year and half, under current law. For perspective, the pre-pandemic peak output gap was 0.9 ppts, while the highest in recent history is 2.4% in 2000Q2.

It’s interesting to note that the CBO projection is based on an assumption the Fed first starts reducing the Fed Funds rate in 2025Q1; this contrasts with projected rate reduction by about 60 bps (on average) by end of 2024 in the February projection.
