According to the Federal Reserve’s Underlying Inflation Gauge, the 12-month inflation growth in June (the most recent month reported) was at 3.33 percent. That’s the highest rate recorded in 158 months, or more than 13 years. The last time the UIG measure was as high was in April 2005, when it was at 3.36 percent.
The Fed began publicly reporting on new measure in December of last year, and takes into account a broader measure of inflation than the more-often used CPI measure.
Not shockingly, the UIG has shown a higher rate of inflation than the CPI, most of the time in recent years, although this gap has narrowed in recent months.
For both CPI and UIG, the general trend has been upward since 2014. The UIG, however, stands out because it shows a sizable amount of price inflation compared to the recent past. the CPI growth rate, for example, remains below where it was in 2011, while we must go all the way back to 2004 to find a UIG growth rate comparable to what we’re seeing now.
Moreover, the UIG holds promise as a better indicator of an approaching recession. For example, we know that the economy was already softening in 2006 and into 2007 before the last financial crisis. And yet the CPI shows continued and sizable growth right up until late 2008 even though the Great Recession had started in late 2007 — at least according to the NBER. The UIG, however, shows weakening prices before both of the two most recent recessions.
The most recent UIG data, however, is fairly old — being June data — so it remains to be seen if there is any sign, by this measure, of a weakening economy in late 2018.
