US inventory-to-sales ratio sinks to 5-year low, fueling inflation fears

The US business inventory-to-sales ratio dropped to its lowest level since 2021, a sign that demand continues to outpace supply in a way that could keep inflation stubbornly above the Federal Reserve's 2% target.

"Lean inventories relative to sales mean companies have less buffer to absorb demand shocks, which typically translates into upward pressure on prices," said Sarah Miller, chief US economist at Oxford Economics.

The ratio has declined steadily over the past three quarters, reversing the inventory glut that characterized much of 2023 and 2024, when retailers and wholesalers accumulated excess stock amid shifting consumer preferences. The 2-year Treasury yield rose 8 basis points to 4.52% following the release, while the 10-year yield climbed 5 basis points to 4.38%. The yield curve remains inverted at minus 14 basis points, a signal that has persisted for more than two years.

The tightening inventory picture complicates the Fed's path forward. With the policy rate at 5.25% to 5.5% and markets pricing roughly two quarter-point cuts by year-end, persistent price pressures could delay any easing. The next Fed meeting on Sept. 17 will offer the first opportunity for policymakers to adjust their stance.

The ratio's decline reflects a structural shift toward just-in-time inventory management after the costly writedowns that followed the 2023-2024 glut. Commerce Department data show that while sales have remained resilient — supported by a labor market that added an average of 172,000 jobs per month over the past three months, with the unemployment rate at 4.1% — inventory growth has lagged. Businesses are prioritizing capital spending on technology and AI infrastructure over stockpiling physical goods, a trend that has funneled billions into data center construction and semiconductor fabrication. Corporate capital expenditure on AI-related projects is projected to exceed $300 billion this year, according to industry estimates.

For the Fed, lean inventories mean any uptick in demand could translate more quickly into price increases. The disinflationary tailwind from inventory normalization has largely run its course, leaving core inflation more dependent on the trajectory of services prices and wage growth. Core PCE, the Fed's preferred inflation gauge, has hovered around 2.7% for the past four months, well above the central bank's 2% target. The Atlanta Fed's wage growth tracker stands at 4.8%, a level historically inconsistent with the Fed's inflation goal.

The last time the ratio was this low was mid-2021, when supply-chain bottlenecks were at their peak and inflation was beginning its historic surge. Headline CPI accelerated from 5.4% to 9.1% over the following 12 months. While supply chains have since healed and the labor market has cooled from its 2022 peak, the precedent highlights the risk that lean inventories could amplify price pressures if demand surprises to the upside. Consumer confidence has improved in recent months, with the Conference Board's index rising to 102.3 in June from 98.1 in March.

For equity investors, the implications are nuanced. Small-cap stocks, which tend to be more domestically focused and sensitive to the economic cycle, could benefit from a stronger-than-expected economy. The Russell 2000 edged up 0.2% on the day. However, the prospect of delayed rate cuts poses a headwind for growth stocks and rate-sensitive sectors. The S&P 500 traded 0.3% lower, while the tech-heavy Nasdaq Composite fell 0.5% as AI-related names faced renewed valuation scrutiny. The S&P 500's forward price-to-earnings multiple of 21.3 remains above its 10-year average of 18.5, leaving it vulnerable to repricing if rate expectations shift.

The gold market is sending its own signal about the inflation outlook. Bullion prices have held above $2,400 an ounce, supported by expectations that central banks will maintain accommodative policies even as inflation proves sticky. That dynamic — rising gold alongside sticky inflation — historically has been a negative for bonds, as it suggests investors are losing confidence in central banks' ability to control prices. The 10-year real yield has risen to 1.85%, reflecting the market's adjustment to a higher-for-longer rate environment. Gold has gained 14% year-to-date, outperforming both the S&P 500 and long-duration Treasuries.
