US inflation surprises signal persistent risks
What the chart shows
This chart illustrates the relationship between US underlying inflation and inflation surprises, with inflation surprises pushed ahead by 12 months. It tracks various measures of underlying inflation alongside the US Citi Inflation Surprise Index. The chart suggests that the inflation surprise index tends to lead actual underlying inflation by about twelve months, showing a predictive relationship across different inflation measures.
Behind the data
Although US Consumer Price Index (CPI) inflation {{nofollow}}in April moderated and was relatively close to expectations, both headline and core CPI measures have consistently exceeded consensus estimates for several preceding months. This has driven increases in the economy’s inflation surprise index.
Given the higher and more positive trend of overall US inflation surprises, inflationary risks may persist. This persistent inflation risk complicates the Federal Reserve’s decision-making process regarding its monetary policy stance. While the Fed has been considering a shift from a hawkish to a dovish approach, continued inflation surprises may keep such a shift uncertain.
