How Much Can GSCPI Improvements Help Reduce Inflation?
Inflationary pressures—their determinants and evolution—continue to dominate policy discussions. In this post, we provide a simple framework to analyze the determinants of different measures of inflation and use it to lay out a risk-scenario analysis. We find that global supply factors captured by the New York Fed’s Global Supply Chain Pressure Index (GSCPI) are strongly associated with inflationary developments measured by the producer price index (PPI) and by the c0nsumer price index (CPI). Under the assumption that the GSCPI falls back to its historical average over twelve months, our model would project a substantial easing of consumer price inflation over 2023 to below 4.0 percent. The normalization of the GSCPI would then be consistent with a return of inflation to levels consistent with a soft-landing scenario.
How Have Swings in Demand Affected Global Supply Chain Pressures?
In a January 2022 post, we first presented the Global Supply Chain Pressure Index (GSCPI), a parsimonious global measure designed to capture supply chain disruptions using a range of indicators. The spirit of our index was to isolate supply factors, such as shutdowns in response to the pandemic, that put pressure on the global supply chain. In this post, we describe an auxiliary index, the Net GSCPI, which differs from the GSCPI by not filtering out demand factors. This “net” index is meant to capture global supply chain stress from both the supply and demand sides. Our analysis documents that the net index is currently below its historical average, unlike the original index, due to both the easing of supply constraints and a contraction in global demand.
Global Supply Chain Pressure Index: The China Factor
In a January 2022 post, we first presented the Global Supply Chain Pressure Index (GSCPI), a parsimonious global measure designed to capture supply chain disruptions using a range of indicators. In this post, we review GSCPI readings through December 2022, and then briefly discuss the drivers of recent moves in the index. While supply chain disruptions have significantly diminished over the course of 2022, the reversion of the index toward a normal historical range has paused over the past three months. Our analysis attributes the recent pause largely to the pandemic in China amid an easing of “Zero COVID” policies.
Global Supply Chain Pressure Index: March 2022 Update
Supply chain disruptions continue to be a major challenge as the world economy recovers from the COVID-19 pandemic. In a January post, we presented the Global Supply Chain Pressure Index (GSCPI) as a parsimonious global measure that encompasses several indicators used to capture supply chain disruptions. The main purpose of this post is to provide an update of the GSCPI through February 2022. In addition, we use the index’s underlying data to discuss the drivers of recent moves in the GSCPI. Finally, these data are used to create country-specific supply chain pressures indices.
The Global Supply Side of Inflationary Pressures
U.S. inflation has surged as the economy recovers from the COVID-19 recession. This phenomenon has not been confined to the U.S. economy, as similar inflationary pressures have emerged in other advanced economies albeit not with the same intensity. In this post, we draw from the current international experiences to provide an assessment of the drivers of U.S. inflation. In particular, we exploit the link among different measures of inflation at the country level and a number of global supply side variables to uncover which common cross-country forces have been driving observed inflation. Our main finding is that global supply factors are very strongly associated with recent producer price index (PPI) inflation across countries, as well as with consumer price index (CPI) goods inflation, both historically and during the recent bout of inflation acceleration.
