Diesel Inventories Slide to Multi-Year Low Amid Supply Constraints
Global diesel inventories fell to 542 million barrels as of August 21, down 28.5 million barrels year-over-year, according to S&P Global Platts and CERA. Supply bottlenecks are intensifying, with Russia and the Middle East—accounting for about half of global diesel exports—facing sanctions, drone attacks, and disruptions in the Strait of Hormuz. In the US, refinery utilization has surged to a record 98%, while the price spread for light low-sulfur diesel on the US Gulf Coast hit a record high of $98.15 per barrel on September 1. Domestic inventories are below the five-year average for this season, coinciding with peak demand from harvest and heating seasons and refinery maintenance cycles. As diesel remains critical for transportation, agriculture, and freight, these shortages are pushing operational costs higher across commodity supply chains.
US Economists Highlight Renewed Inflation Pressures Transmitting Through Services Sector
Diane Swonk, Chief Economist at KPMG US, noted in a recent analysis that inflation pressures within the supply chain show no sign of easing but appear to be intensifying, based on the latest ISM manufacturing and services price indexes alongside the Federal Reserve’s Beige Book. Manufacturing price increases are largely driven by import costs and tariffs, while the services sector is experiencing cost pass-through fueled by labor shortages and wage gains. Rising transportation and logistics costs are imparting additional inflationary pressure onto service prices, creating a compounding 'aftershock effect.'
Swonk emphasized the Federal Open Market Committee’s pivot from debating whether to raise rates toward assessing the magnitude of tightening required to curb what is perceived as entrenched inflation. The Fed’s reports also highlight a "K-shaped" consumer spending trend, with price-sensitive consumers cutting back while others maintain robust demand. Without further policy action, inflation is unlikely to recede naturally. Wage data from the Atlanta Fed indicate rising pay for job switchers, and although August’s ADP report shows slight moderation in ongoing wage growth, expected upticks in benefits costs next year may continue to pressure service-sector inflation.
Market Implications and Key Upcoming Events
While some diesel supply pressures stem from temporary factors such as the Russia-Ukraine conflict and disruptions in the Strait of Hormuz, prolonged issues could deepen inflationary strains through elevated transport costs. The closed-door discussions among economists cited by Swonk signal market concerns about inflation becoming more entrenched, implying the Fed may face a lengthier and more aggressive rate-hiking cycle. Anticipation of higher and sustained interest rates often puts near-term pressure on equity markets and non-yielding assets like gold.
Notably, gold retains its role as a long-term hedge against inflation and currency depreciation, balancing out short-term sensitivity to rate changes. Key focus now turns to the US consumer price index for September and the Federal Reserve meeting on September 15-16, which will be crucial in assessing inflation trends and future monetary policy directions. These events are poised to influence risk sentiment and price movements across asset classes in the near term.
