Global Supply Chain Pressures Hit Four-Month High in September

The Federal Reserve Bank of New York reported that global supply chain pressures rose in September, reaching their highest level since May. The Global Supply Chain Pressure Index (GSCPI) climbed to 1.28, up from an upwardly revised 1.20 in August. The August figure was initially reported as 1.06.

The GSCPI, which tracks transportation costs and manufacturing indicators, has been published since 1997. A zero value indicates average pressure, while positive values signal higher pressure. The index hit its recent peak in May at 1.81 and its all-time high in December 2021 at 4.43.

Lower-than-average supply chain pressure was last observed in November 2025, with an estimate of -0.21. Earlier in the year, supply chain pressures had begun to ease after reaching a four-year high, partly due to disruptions in the Strait of Hormuz caused by the U.S.-Iran conflict. The pressures eased when some traffic resumed through the strait.

In related news, Bloomberg reported that the Port of Los Angeles, the busiest container hub in the U.S., blocked over 120 million cyberattacks in August. The port’s cybersecurity team identified various types of attacks, including intrusion and malware.
