Last week I mentioned that the regional Fed surveys plus the Chicago PMI can be used as a workaround to account for the effects of hurricanes on Industrial Production. It isn’t pretty and by no means is it perfect, but for the (hopefully only) two or three months that we need it, we can use the workaround to give us the underlying trend in production, particularly for manufacturing.This is a two-step correlation.
The first correlation is between the regional Fed indexes and the ISM manufacturing index. This is something Bill McBride, a/k/a Calculated Risk, has been keeping track of for years. Here’s his graph going back all the way to 2000:
While the correlation isn’t perfect, most notably in the years 2010 and 2011, when the regional Fed average was high, and in 2015 and 2016, when it was too low, in general it holds, with the two rising or falling between positive and negative in tandem, even if we just use the Empire State and Philly indexes.
