- S&P 500 is within striking distance of correction territory alongside the Dow and Nasdaq Composite, both of which briefly dipped into correction since the Iran war began on Feb. 28, after all three indexes had recently touched milestones of 7,000, 24,000, and 50,000 respectively
- Iran's closure of the Strait of Hormuz to most oil exports has sent crude prices soaring, with the Federal Reserve Bank of Cleveland's Inflation Nowcasting tool estimating trailing 12-month inflation will climb 85 basis points, from 2.40% in February to 3.25% in March
- The Federal Reserve has cut its federal funds target rate six times since September 2024, but rising inflation from the oil shock could prompt Chair Jerome Powell and the FOMC to halt rate cuts or consider future hikes
- According to data aggregated by Carson Investment Research strategist Ryan Detrick, the 11 S&P 500 bear markets since 1950 saw their initial 5% declines occur over an average of just 14.5 trading days (about three weeks)
- The current S&P 500 pullback took 35 trading days (seven weeks) to reach a 5% decline — no bear market in 76 years has taken longer than 24 trading days to lose its initial 5%, making the slow descent statistically unique
- A full-fledged S&P 500 bear market would require a 20% or greater drop from its closing high, a threshold the index has not approached despite the geopolitical and inflation headwinds
Why it matters: For investors, the 35-day slide to 5% cuts against 76 years of bear-market precedent — but the oil-driven inflation jump to 3.25% gives the Fed a reason to pause or reverse its six-cut rate-easing cycle, which could be the actual catalyst that transforms a slow grind into a historic decline. A Fed pivot to hikes against a historically expensive stock market is the asymmetric risk the timeline data alone doesn't capture.
