S&P Global Markets Insights monthly GDP (formerly IHS, Macroeconomic Advisers) online today. Here is monthly GDP againnst other NBER BCDC measures:

The monthly GDP is (like all estimates) subject to revision, but it is notable as one of the few output measures going down in May. To look at how monthly GDP compares with other indicators, I consider q/q annualized growth rates:

Monthly GDP is quite volatile, but is not inconsistent with GDPNow and SPGMI’s current tracking estimate of 1.3% q/q AR growth in Q2.
