We just got a sobering wake-up call about inflation from the Bureau of Labor Statistics.
It's bad enough that the marquee number -- May's year-over-year inflation rate -- jumped to 4.2%, a three-year high, but it's also the third straight month-over-month increase of 0.5% or more. The S&P 500 (SNPINDEX: ^GSPC) dipped 1.6% on the news.

Here's what's going on and what history tells investors to do now.
Annual inflation, according to the Consumer Price Index (CPI), stood at just 2.4% in January and February, meaning the average item that cost $100 in February 2025 cost $102.40 in February 2026.
That probably doesn't sound like much of an increase. Indeed, the Federal Reserve's target for annual inflation is 2%, so January's and February's numbers were above the target, but not by much.
That changed after the U.S. launched its war on Iran on the last day of February. Iran's response, closing the Strait of Hormuz to maritime traffic, forced tankers carrying Middle Eastern oil to sit idle and drove the global cost of fuel skyward. U.S. Inflation in March was 0.9% higher than in February, and annual inflation rose to 3.3%.
In April, monthly inflation climbed 0.6%, taking annual inflation to 3.8%, while the recently released May figures show it at 4.2% for the first time since April 2023.
What 4.2% annual inflation means is that our $100 item from May 2025 would cost $104.20 in May 2026. That isn't much more expensive than $102.40. The bigger problem is that inflation compounds, so we also need to consider that the May 2025 item was 2.4% more expensive than in May 2024, when it was 3.2% more expensive than in May 2023, when it was 4.1% more expensive than in May 2022, when it was (yikes!) 8.5% more expensive than in May 2021.
So over five years, the item that cost $100 in May 2021 now costs $124.40, 24.4% more. That's definitely higher than in recent decades. Inflation stayed below the Fed's 2% target for much of the 2010s and below 3% for most of the 2000s.
Most of the current inflation is caused by soaring energy prices, especially gasoline (up 40.5% year over year) and fuel oil (up 58.9%). Stripping out food (up 3.1%) and energy, the CPI rose only 2.9% in May, but that's cold comfort to consumers and businesses watching their fuel costs rise by double-digit percentages.
If the Iran war ends for good with an agreement to keep the Strait of Hormuz open and free of tolls, energy prices should recede, and overall inflation should fall as a result. But although a resolution is looking more likely than it did in the spring, it's still far from a done deal.
The most important thing history tells us to do, though, is to grit our teeth and wait. Selling stocks now -- especially when inflation may be about to get lower -- would be a textbook example of trying to time the market. History has shown that investors who wait out periods of geopolitical uncertainty almost always end up better off than those who don't.

Four leading AI models discuss this article
"Inflation timing and policy durability, not the headline 4.2% CPI, will determine market direction and sector winners."
Today’s CPI at 4.2% signals energy-driven inflation is not solved, but not a systemic collapse either. The real risk to a pure 'stay the course' thesis is policy error: if the Fed keeps rates restrictive longer or if real yields rise, valuations on growth stocks could compress even with energy moderating. Conversely, a quick Hormuz resolution that eases energy costs could let inflation fade and support multiple expansion. The article glosses over sector dispersion and relies on marketing stock tips. My stance: neutral, with a tilt toward selective cyclicals (energy, materials) and high-quality defensives, avoiding broad bets on a blanket 'wait it out' call.
The inflation spike could prove stickier than expected, forcing an earlier and higher-for-longer rate path than investors assume, crushing high-mrowth tech multiples. Even if Hormuz eases, structural supply constraints and wage pressures could keep core inflation elevated, making 'wait' a meaningful headwind for broad equities.
"Persistent energy-driven inflation will force a re-evaluation of corporate margin sustainability, leading to a downward revision of forward P/E multiples across the S&P 500."
The article’s reliance on 'stay the course' advice ignores the structural shift in real interest rates. With CPI at 4.2% and the Fed likely forced to keep the federal funds rate elevated to combat supply-side shocks from the Strait of Hormuz, the 'cost of carry' for leveraged equities is rising. While the article frames this as a transitory energy spike, it glosses over the secondary effects: wage-price spirals and input cost inflation hitting corporate margins. I am bearish on the S&P 500 here, specifically the consumer discretionary sector, which will face severe margin compression as households reallocate spending from goods to essential energy costs. Expect earnings downgrades in Q3.
If the geopolitical conflict resolves quickly, the resulting 'relief rally' in energy-sensitive sectors could trigger a rapid mean reversion in inflation expectations, making current equity valuations look like a generational buying opportunity.
"Three consecutive 0.5%+ monthly CPI prints signal structural inflation momentum, not transitory energy shock, and the market's 1.6% dip understates the re-rating risk if the Fed doesn't cut in July."
The article conflates two separate problems. Yes, 4.2% YoY inflation is elevated, but the real stress test is the *trajectory*: three consecutive 0.5%+ monthly prints suggest momentum, not a temporary spike. Energy-stripping to 2.9% core CPI is presented as reassuring, but that's backwards—it means the inflation is concentrated in the most volatile, least controllable component. The Iran geopolitical assumption is doing heavy lifting here: the article assumes resolution is 'more likely' without quantifying base rates or downside scenarios. Critically, the Fed's reaction function is absent. If the Fed holds rates steady through summer despite this data, it's implicitly accepting higher inflation or signaling recession fears. If it cuts, that's a different market signal entirely.
If energy prices have already peaked (Brent crude has been range-bound for weeks) and the monthly momentum is just mean reversion, then waiting out the noise—as the article suggests—is exactly right, and selling now locks in losses before the rebound.
"Persistent Hormuz disruption risks turning a 4.2% headline into sustained 3%+ core inflation that forces tighter policy longer than the article assumes."
The 4.2% May CPI print, driven by 40.5% YoY gasoline and 58.9% fuel oil spikes after the Strait of Hormuz closure, marks a structural energy shock rather than transitory noise. Compounding from the prior 2.4% base already produces a 24.4% cumulative price level rise since May 2021. History of quick recoveries after geopolitical events assumes rapid de-escalation; here the article provides no evidence the conflict ends soon enough to prevent second-round wage or rate effects. Energy-driven inflation at this magnitude typically widens dispersion between defensives and cyclicals, not a uniform buy-the-dip signal.
If the war resolves within weeks as the article hints is increasingly likely, the energy spike reverses fast enough that the S&P 500's post-shock rebounds seen in 1990 and 2003 still apply, rendering the current dip a short-term overreaction.
"Even if Hormuz tensions ease, second-order effects and duration risk imply dispersion persists and broad equities remain vulnerable, not just energy spikes."
Grok's energy-shock thesis overstates the confidence around near-term de-escalation: even if Hormuz tensions ease, second-order effects—wage inflation, capex cycles, and rate-anticipation by the Fed—mean dispersion can persist for longer than a single energy spike. The assumption that a quick rebound follows is binary. Markets price a path, but duration risk in equities grows if high-rate regimes persist. Bearish on broad equities, but keep selective energy/defensive hedges.
"Persistent fiscal stimulus will keep inflation elevated and force a structural re-rating of equity multiples regardless of energy price volatility."
Claude is right that the Fed's reaction function is the missing variable, but everyone is ignoring the fiscal side. Government spending remains a massive tailwind for aggregate demand, effectively neutralizing the Fed's restrictive stance. Even if energy prices retreat, the fiscal impulse ensures inflation stays above the 2% target. We aren't looking at a simple 'wait it out' scenario; we are looking at a permanent shift in the neutral rate that makes current equity multiples unsustainable.
"Fiscal tailwind is cyclical, not structural; conflating it with energy supply shocks obscures which sectors actually benefit from higher rates and tighter fiscal."
Gemini's fiscal-impulse argument is underspecified. Yes, government spending supports demand, but it's already priced into forward guidance—the Fed raised rates *knowing* fiscal was loose. The real question: does fiscal persist through 2025, or does the political cycle force consolidation? If the latter, the 'permanent neutral rate shift' collapses. Also, Gemini conflates demand-side inflation (fiscal) with supply-side (energy). They behave differently under rate pressure. Energy shocks compress margins; fiscal stimulus can actually support margins if it lifts demand faster than costs.
"Fiscal persistence plus energy costs risks entrenching wages, complicating the Fed's tradeoff more than supply-side analysis alone indicates."
Claude separates fiscal demand from energy supply shocks but underplays how sustained government spending could lock in wage-price spirals after the Hormuz-driven gasoline spike. If political consolidation slips past 2025, the Fed confronts simultaneous demand and supply pressures that neither rate path nor quick de-escalation resolves cleanly. This interaction widens the window for margin compression in cyclicals beyond isolated energy effects.
The panel consensus is bearish, with energy-driven inflation and potential policy errors posing significant risks. The Fed's reaction function and fiscal spending are key uncertainties.
