Provide chain disruptions proceed to be a serious problem because the world financial system recovers from the COVID-19 pandemic. In a January put up, we offered the Global Supply Chain Pressure Index (GSCPI) as a parsimonious world measure that encompasses a number of indicators used to seize provide chain disruptions. The primary function of this put up is to offer an replace of the GSCPI by way of February 2022. As well as, we use the index’s underlying knowledge to debate the drivers of latest strikes within the GSCPI. Lastly, these knowledge are used to create country-specific provide chain pressures indices.
Up to date GSCPI
The chart beneath reveals the GSCPI by way of February 2022, and it factors to an easing in world provide chain pressures since December 2021 regardless that they continue to be at traditionally excessive ranges (download data).
Whereas World Provide Chain Pressures Are Lowering, Strain Nonetheless Stays Excessive
Word: Every index is scaled by its commonplace deviation.
To see what drove this latest easing in provide chain strain, it might be helpful to summarize how the GSCPI is constructed. As detailed in our original post, the GSCPI relies on two units of knowledge. World transportation prices are measured by utilizing knowledge on sea transport prices, for which we make use of knowledge from the Baltic Dry Index (BDI) and the Harpex index, in addition to BLS airfreight cost indices for freight flights between Asia, Europe, and the United States. We additionally use three provide chain-related parts— “supply occasions,” “backlogs,” and “bought shares”—from the Purchasing Managers’ Index (PMI) surveys for manufacturing corporations throughout seven interconnected economies: China, the euro space, Japan, South Korea, Taiwan, the UK, and the USA.
Earlier than we mix these inside the GSCPI by way of principal part evaluation, we strip out demand results from the underlying knowledge sequence by projecting the PMI provide chain parts on the “new orders” part from the corresponding PMI surveys and, in an identical vein, we try this for the worldwide transportation value measures which might be projected onto the GDP-weighted “new orders” and “inputs bought” parts throughout the seven PMI surveys. This try at isolating provide aspect strikes could be very a lot harking back to related approaches which were proposed by the Worldwide Financial Fund (see the newest World Economic Outlook, web page 47) and the Financial institution of England (see the Monetary Policy Report, web page 28), though we exploit extra info by permitting for cross-country linkages and by together with varied measures of transportation prices.
So, what has pushed the easing of world provide chain pressures noticed since December? Within the subsequent chart, we give attention to the decline between January and February. Every column represents the contribution in commonplace deviation of every part of our index towards its total change. Word that the lessening of provide chain pressures has been widespread among the many varied parts, which is a welcome growth when it comes to decreasing world provide chain disruptions.
Most GSCPI Parts Decreased in February 2022
The cautious reader could have seen some numerical variations between the present classic of the GSCPI and people printed earlier. Though we assemble the GSCPI between 1997 and the current, we famous in our unique put up that a few of our underlying knowledge begin later than 1997, whereas different sequence are printed with a one-month lag. Consequently, we now have knowledge gaps each early within the pattern in addition to on the finish. We take that under consideration when estimating the widespread part throughout the sequence by way of principal part evaluation and within the course of impute estimated values into these knowledge gaps, as advised by Stock and Watson (2002). Due to this fact, GSCPI ranges of the latest months may be revised as realized knowledge grow to be out there and change these imputed values. As well as, for a few of the sequence, primarily the BLS airfreight value indices, every new launch comes with revisions to as much as twelve months of earlier knowledge. The chart beneath compares the present launch of the GSCPI with the earlier three releases, and it reveals that revisions can have an effect as much as a 12 months again in time. The chart moreover reveals that the present classic of the GSCPI means that world provide chain pressures peaked in December, whereas the earlier classic had pressures reaching the very best ranges in November. Each vintages means that 2022, no less than as much as February, has seen a lower in world provide chain disruptions.
Revised and Realized Knowledge Can Alter Earlier Provide Chain Strain Readings

Nation-Particular Provide Strain Indices
The info set for our GSCPI consists of PMI knowledge for seven international locations: China, the euro space, Japan, Korea, Taiwan, the UK, and the USA. We will make the most of these knowledge along with our world transportation measures to approximate provide chain pressures in these economies. This entails taking the “supply occasions,” “backlogs,” and “bought shares” parts of a particular nation’s PMI survey and including the transportation value measures, reworked into native forex phrases. In relation to those transportation value sequence, the transport value proxies are world and thus all the time thought-about for a rustic, whereas solely the related regional airfreight value measures are used—that’s, the price of airfreight between the U.S. and Asia for China, Japan, South Korea, and Taiwan, the price of airfreight between the U.S. and Europe for the euro space and the U.Ok., and all airfreight prices measures for the U.S.
We due to this fact have six sequence per nation, aside from the USA, the place we now have seven. In an identical vein as in case of the GSCPI, we use regressions based mostly on PMI demand proxies and their lags to cleanse every nation’s knowledge set as a lot as potential from demand results. The cleansed sequence are then included in a principal part evaluation on the nation degree, the place for every nation a standard part is estimated whereas knowledge gaps are concurrently imputed with preliminary estimates.
Within the two charts beneath, we plot our constructed indices for our seven economies. The primary chart depicts our country-specific provide chain proxies for the euro space, Japan, the U.Ok., and the U.S. Provide chain pressures attain new highs in latest months for these economies however began to ease shifting into 2022. Within the instances of China, South Korea, and Taiwan, as proven within the second chart beneath, we additionally discover some easing in provide chain pressures heading into February after coming off contemporary peaks on the again of COVID-related lockdowns within the area, with China lagging considerably relative to South Korea and Taiwan.

We notice that whereas there are co-movements among the many regional indices, idiosyncratic fluctuations in these measures do happen, reflecting country-specific components. For instance, we observe a rise within the Chinese language index through the so-called commerce warfare tensions with the U.S. Curiously, the post-Brexit interval doesn’t appear to have resulted in a notable enhance within the U.Ok. strain index. A notable caveat with these country-specific indices is that they are often noisier and thus much less exact in measuring provide chain pressures than the GSCPI, as they’re based mostly on a smaller set of inputs that restrict the scope to “diversify away” noisy options within the underlying knowledge and so they ignore cross-country linkages which might be on the coronary heart of the availability chain connections amongst manufacturing corporations.
Conclusions
On this put up, we offer an replace of the GSCPI and introduce proxies for country-specific provide chain pressures. General, we notice that provide chain pressures have moderated relative to the height reached in December 2021, however these pressures have remained at traditionally elevated ranges by way of February. Going ahead, there may be the likelihood that the present heightened geopolitical tensions may result in extra elevated provide chain pressures within the close to future.
