Despite a turbulent year for America's foremost financial institution, the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite have all climbed to record highs.
The Iran war is hitting consumers' pocketbooks and ramping up inflation.
The Cleveland Fed's proprietary inflation forecasting tool points to another sizable increase in May, which could eventually force the central bank into action.
It's been a tumultuous past year for our nation's foremost financial institution, the Federal Reserve. We've witnessed an ongoing spat between President Donald Trump and now-former Fed Chair Jerome Powell over interest rates, and observed a historic level of division within the Federal Open Market Committee (FOMC) -- the 12-person body responsible for setting U.S. monetary policy.
Despite this, the Dow Jones Industrial Average (DJINDICES: ^DJI), S&P 500 (SNPINDEX: ^GSPC), and Nasdaq Composite (NASDAQINDEX: ^IXIC) have all reached new heights. The question is: Can they stay there, following growing concerns about inflation?

Although Powell frequently referenced the price stickiness of Trump's tariffs in the goods sector when discussing elevated inflation, the bulk of the worry at the moment centers on the Iran war, which began on Feb. 28.
Shortly after the U.S. and Israel commenced attacks against Iran, the latter closed the Strait of Hormuz to virtually all commercial vessels. This stymied the transport of 20 million barrels of petroleum liquids per day (about 20% of global demand), representing the largest energy supply disruption in history.
⛽ Average U.S. gas prices per gallon on May 6, per AAA:
-- NBC News (@NBCNews) May 6, 2026
• Regular: $4.54 (⬆️ $1.56 since war in Iran began on Feb. 28)
• Premium: $5.39 (⬆️ $1.85 since war began)
• Diesel: $5.67 (⬆️ $1.81 since war began)
There was an immediate response in energy markets, with crude oil prices soaring. Consumers have seen gas prices rise at the fastest pace in 30 years.
But this may be just the beginning. The inflationary effects on businesses often lag a few months. Once higher production and transportation costs are accounted for in economic data, U.S. inflation can rise further.
Before the Iran war began, trailing 12-month (TTM) U.S. inflation clocked in at 2.4%. In the subsequent two months, the Bureau of Labor Statistics reported TTM inflation of 3.3% (March) and 3.8% (April). Inflation has jumped to a three-year high in the blink of an eye -- and it's not done yet.
According to the latest forecast from the Federal Reserve Bank of Cleveland's Inflation Nowcasting tool, TTM inflation for May is estimated at 4.18% (as of May 15). Worse yet, the quarterly annualized Consumer Price Index is pacing a 6.89% increase for the second quarter!
When 2026 began, Wall Street and investors had been factoring in several rate cuts for 2026-2027. Lower lending rates were expected to fuel the artificial intelligence data center build-out and prop up a historically expensive stock market. The only time the S&P 500's Shiller Price-to-Earnings Ratio has been higher over the last 155 years was in the lead-up to the bursting of the dot-com bubble.

The inflationary spike from the Iran war has effectively removed any chance of rate cuts in 2026, and perhaps beyond. It may even coerce the FOMC to raise rates if prices continue trending higher.
Further complicating matters is the ascension of new Fed Chair, Kevin Warsh. Warsh's previous time on the FOMC (Feb. 24, 2006 – March 31, 2011) shows he favored higher interest rates to suppress inflation. Warsh will also be tasked with overseeing a fractured FOMC. If dissenting opinions persist, the nation's central bank could lose some of its hard-earned credibility.
The Fed's latest inflation update is nothing short of nightmare fuel for the stock market.

Four leading AI models discuss this article
"Energy-shock inflation at peak valuations removes rate-cut support and raises the odds of valuation compression for the S&P 500."
The article correctly flags how the Iran conflict's closure of the Strait of Hormuz has triggered the fastest gas-price surge in 30 years, lifting Cleveland Fed nowcasts to 4.18% May CPI and 6.89% Q2 annualized. At current Shiller PE levels only 5% below the 2000 peak, removal of 2026 rate-cut expectations plus a hawkish new Chair Warsh raises the probability of multiple compression in the broad market. Energy cost pass-through into core services inflation could extend the shock beyond the initial headline spike, pressuring multiples even if growth holds.
Geopolitical energy shocks have historically resolved within 3-6 months via diplomatic or military means, allowing supply to rebound and inflation expectations to fall before the Fed needs to act aggressively.
"The article overstates the threat by treating a Cleveland Fed nowcast as destiny and ignoring that energy-driven headline inflation rarely forces sustained rate hikes if core inflation remains anchored."
The article conflates correlation with causation on inflation. Yes, gas prices spiked $1.56/gallon since Feb 28, but the Cleveland Fed's 4.18% May TTM forecast is speculative—it's a nowcast, not realized data. More critically: energy is ~8% of CPI. Even if oil stays elevated, pass-through to core inflation (ex-food/energy) is slower and weaker than headline suggests. The real risk isn't May inflation—it's whether the Fed *believes* this is persistent. Warsh's hawkish history matters, but one chair doesn't set policy alone. The article ignores that equity valuations already priced in zero cuts; further repricing is possible but not inevitable if inflation proves transitory.
If Iran conflict escalates further or geopolitical risk spreads to other chokepoints, energy shocks could compound faster than historical lags suggest, forcing genuine stagflation rather than temporary headline noise.
"The market is currently betting on AI-driven productivity gains to offset energy-led cost-push inflation, a high-stakes gamble that hinges entirely on whether the Fed avoids a policy-induced recession."
This article is a classic example of 'fear-mongering' disguised as financial analysis. While the geopolitical disruption in the Strait of Hormuz is undeniably inflationary, the piece ignores the massive deflationary potential of the AI-driven productivity boom. If we are seeing record highs despite a 6.89% annualized CPI, it suggests the market is pricing in a 'new normal' where corporate margins are protected by automation, not just pricing power. A Shiller P/E near dot-com levels is concerning, but if earnings growth remains double-digit, the valuation is less 'bubble' and more 'structural shift.' The real risk isn't just inflation; it's the Fed over-tightening into a supply-side shock, which would be a policy error of historic proportions.
The market may be ignoring the 'lag' effect; if the Iran conflict persists, the erosion of consumer discretionary income will eventually crater corporate earnings, rendering current high valuations completely indefensible.
"Inflation remains the main risk to equities, but its impact will be uneven and the AI capex cycle could sustain earnings for selective names even as valuations risk re-pricing the broader market."
The piece frames May inflation as a doom loop for stocks, anchored by the Cleveland Nowcasting estimate and a hawkish tilt under Warsh. But the inflation picture is diverging: energy-price spikes could be temporary if supply routes normalize, while core services and wages may evolve differently and could slow, suggesting policy impact will be non-linear. Valuations look stretched, especially on Shiller P/E, yet AI-related capex could sustain earnings power for select names even if the broad market cools. A key omission is model risk around nowcasting and the political/regulatory dimension of Warsh’s leadership that could surprise markets.
If energy costs stay elevated and wage growth accelerates, the Fed could stay hawkish longer and multiples could compress faster, delivering a downside surprise to the broad market.
"Wage-energy loops will outrun concentrated AI productivity gains, locking in higher inflation prints."
Claude underplays how quickly energy costs feed into services wages in a still-tight labor market, turning the 8% CPI share into a persistent anchor for expectations. Gemini's AI productivity offset assumes broad deployment that most non-tech firms simply lack the capex scale to achieve before consumer fuel bills erode discretionary spending. If Hormuz tensions linger past Q3, the Cleveland nowcast's 6.89% Q2 print may embed rather than fade, validating Warsh's stance and forcing earlier multiple compression outside mega-cap tech.
"Nowcast confidence intervals matter more than point estimates for policy signaling, and the article omits them entirely."
Grok's wage-anchor mechanism is plausible but assumes energy-cost pass-through outpaces historical lags. The tighter labor market does amplify this risk. However, Claude's point about nowcasts being speculative deserves more weight—Cleveland Fed's 4.18% May estimate has a wide confidence band the article doesn't disclose. We're treating a model forecast as near-certainty. If realized May CPI comes in 3.2-3.5%, the entire multiple-compression thesis collapses. That's the real tail risk nobody quantified.
"Energy-driven supply shocks will increase operational costs for AI infrastructure, negating productivity gains and forcing downward earnings revisions."
Gemini’s 'AI productivity' argument is a dangerous distraction. We are seeing a supply-side shock, not a demand-side efficiency gain. If energy costs spike, the capital required to run energy-intensive AI data centers will balloon, crushing margins for the very tech companies holding up the S&P 500. Grok is right about the wage-anchor risk, but the real threat is that higher energy costs act as a tax on the entire S&P 500, forcing earnings revisions downward.
"Persistent energy shocks will pressure earnings and multiples more than AI-driven productivity can offset in the near term."
Responding to Gemini: AI productivity is an appealing narrative, but a persistent energy shock is a near-term margin headwind that most non-tech firms can't offset through automation. If Hormuz tensions linger, energy costs act like a persistent tax on earnings and cash flow, pressuring multiples well before AI-driven efficiency shows through. The real risk isn't a one-off inflation spike but a broader earnings downgrade from higher fuel, logistics and capex costs converging with sticky wages.
The panel discusses the impact of the Iran conflict on inflation and markets, with a majority expressing concern about persistent inflation and its effect on stock multiples. They disagree on the extent and duration of the impact, with some seeing it as transitory and others as more persistent.
