10-year US Treasury yields jumped 15.5 basis points to 5.11%, reaching their highest level since 2007 amidst rate hike fears.
Brent crude rose 3.86% to $103.08 per barrel, despite US Energy Information Administration (EIA) crude oil inventories building by 2.97 million barrels.
The S&P 500 fell 0.75% to 7,706 as markets priced in a 70% probability of an October Federal Reserve interest rate hike.
Cintas Corporation dropped 3.44% despite reporting strong quarterly revenue of $3.01 billion and earnings per share (EPS) that exceeded market expectations.
US Treasury yields jump as equities fall amid persistent inflation pressures
US equity markets declined in tandem amidst rising oil prices and surging Treasury bond yields—two factors underscoring how bondholders are pricing in potential interest rate hikes by the Federal Reserve to contain inflationary pressures.
At market close, the Brent crude futures contract (BRNX6) had advanced by 3.86% to $103.08 per barrel, whilst the West Texas Intermediate (WTI) futures contract (CLX6) rose 2.00% to $92.22 per barrel. In this context, energy traders evaluated a speech by Iranian President Masoud Pezeshkian at the UN General Assembly, in which he asserted that Tehran would never surrender to US pressure.
Following the rally in oil prices and these geopolitical developments, data from the CME FedWatch Tool indicated an approximate 70% market-implied probability that the Federal Reserve will hike interest rates at its October meeting. Furthermore, as reported by Reuters, Federal Reserve Governor Michael Barr stated that, given escalating inflation risks and economic resilience, the US central bank will likely deliver additional rate increases.
Against this backdrop, benchmark 10-year US Treasury yields jumped 15.5 basis points to 5.11%—their highest level since 2007. This surge reflects mounting selling pressure from bondholders pricing in further interest rate hikes by the Federal Reserve amidst an environment of elevated government debt that continues to weigh on investor confidence. Concurrently, 2-year Treasury yields advanced 15 basis points to reach 4.90%, hitting their highest level since May 2024.
Consequently, US equity benchmarks fell in unison as crude prices and bond yields climbed. The S&P 500 index decreased by 0.75% to 7,706 points, the Dow Jones Industrial Average declined 0.68% to 51,517, and the Nasdaq 100 index dropped 0.85% to 30,470 points. Notably, despite today's pullback, the S&P 500 and Nasdaq 100 indices remain close to their record highs.
EIA crude oil inventories increase well above market expectations
According to weekly data released by the US Energy Information Administration (EIA), commercial crude oil inventories increased by 2.97 million barrels, contrasting sharply with consensus analyst forecasts of a 0.6 million barrel drawdown. This build represents the largest weekly crude accumulation in four weeks. While overall inventory levels do not exceed historical averages, the primary factor for market participants is that the reading came in significantly above market expectations.
Additionally, the EIA reported that gasoline inventories fell by 1.69 million barrels, exceeding analyst estimates of a 0.1 million barrel drawdown. This reduction suggests that the buildup in crude stockpiles was likely not driven by weakening end-user demand.
Against this backdrop, WTI futures largely disregarded the crude accumulation, rising 2.00% by market close as market focus remained anchored on persisting geopolitical tensions in the Middle East.

Cintas Corporation shares fall despite better-than-expected quarterly earnings
Cintas Corporation published a solid quarterly earnings report, exceeding market consensus on both total revenue and earnings per share (EPS). The company delivered revenue of $3.01 billion, topping Wall Street estimates of $2.98 billion, whilst EPS came in at $1.36, slightly above the $1.35 forecast. These figures represent a year-on-year (YoY) revenue growth rate of 10.6% and an annual EPS increase of 13.3%. However, despite beating expectations, Cintas shares dropped 3.44% as investors subjected corporate earnings to heightened scrutiny amidst broader macro uncertainty.
Cintas' earnings release highlighted a 15.2% increase in operating income, expanding operating margins to 23.6% as a percent of revenue—up from 22.7% a year prior. Furthermore, demonstrating its commitment to returning capital to shareholders, the company distributed $208.8 million in quarterly dividends and allocated $544.7 million to share buyback programmes. Finally, management raised its full-year financial guidance for both total revenue and EPS.
