A Quarter Defined by War, Disruption, and a Sharp Reset in Leadership
What began as a year focused on earnings growth, AI enthusiasm, and eventual Fed easing turned into a quarter dominated by the Iran war, an oil shock, a violent software selloff, and rising concerns about liquidity in private credit. By quarter-end, the S&P 500 had fallen 4.3%, the Dow had fallen 3.2%, and the Nasdaq had fallen 7.0%. Both the Dow and Nasdaq entered correction territory during March, and the S&P 500 posted its worst quarter since the second quarter of 2022.
Before the War, Capex Was the Story
Before geopolitics took over the market narrative, investors were focused on a very different question: could the massive increase in capital spending by large technology companies ultimately justify the market’s enthusiasm around AI?
During earnings season, major tech companies outlined enormous spending plans tied to AI infrastructure, data centers, chips, networking, and cloud capacity. The debate was not whether spending was rising. It clearly was. The real question was whether that spending would translate into durable revenue growth, wider margins, and meaningful returns on capital across the technology ecosystem.
For a time, investors were willing to give the biggest AI-linked companies the benefit of the doubt. But as the quarter wore on, that optimism began to fade. The market started asking a tougher question: who will actually capture the economic payoff from all of this spending? That made the late-quarter selloff in software and AI-linked names especially notable. Investors moved from celebrating spend to questioning whether anyone beyond the infrastructure winners would truly monetize it.
Story #1: The Iran War Became the Quarter’s Defining Macro Event
The single biggest story of the quarter was the Iran war, which began in late February and quickly reshaped both the economic outlook and the market’s closing weeks. What made it so important for markets was not only the geopolitical danger, but the economic implications. The Strait of Hormuz handles roughly one-fifth of global oil and LNG transit, and fears of prolonged disruption drove one of the sharpest jumps in oil-price forecasts on record. Crude oil surged 77% during the first quarter.
That mattered immediately. Higher oil prices fed into inflation fears, reduced confidence that the Fed would be able to ease policy, pressured consumer sentiment, and weighed on growth-sensitive parts of the market. What started as a geopolitical event quickly became an inflation and interest-rate event too. By the end of the quarter, investors were no longer asking only whether the economy could slow gently. They were asking whether the U.S. might have to deal with some version of slower growth and stickier inflation at the same time.
Story #2: “Software Armageddon” Became a Real Market Theme
Another major story in the quarter was the sharp repricing across software and cloud stocks. Investors began asking a tougher question: if newer AI models from firms such as Anthropic can increasingly automate enterprise tasks, does that threaten the economics of parts of the traditional software stack?
Reuters Breakingviews described this as a potential software meltdown, noting that the BVP Nasdaq Emerging Cloud Index fell 14% in just over a week during early February as investors began to worry that AI-native tools could make some incumbent software offerings less essential. Reuters also linked the selloff to private markets, where many buyout firms had significant exposure to software assets purchased at much higher valuations.
This theme mattered because software had long been one of the market’s favorite growth categories. Suddenly, investors were rethinking familiar names such as Salesforce, Workday, ServiceNow, Atlassian, HubSpot, and Adobe through a different lens. Instead of rewarding them simply for recurring revenue and scale, the market began to ask whether AI could compress pricing power, reduce seat counts, or weaken the value of certain products altogether. That shift in thinking put pressure not only on software valuations, but on the broader technology complex as well.
Story #3: Private Credit Stress Exposed a New Layer of Risk
Private credit was another major story that moved from the background to the foreground in 1Q26. Reuters reported that several major firms in the space, including BlackRock and Apollo, limited withdrawals as redemption pressure rose, while Ares also capped redemptions. JPMorgan even filed for a new vehicle structure that explicitly allows limited quarterly redemptions, underscoring how central liquidity management has become in the sector.
The larger concern was what those gates implied. Investors became more focused on the combination of illiquid underlying loans, opaque pricing, and heavy exposure to stressed borrowers, including software-related companies. Reuters reported that some private lenders had increasingly relied on payment-in-kind structures and covenant relief to avoid defaults, while Fed Chair Jerome Powell said the central bank was watching the sector for signs of trouble, even if it was not yet being described as systemic.
That does not mean private credit is facing a 2008-style crisis. But it does mean that one of Wall Street’s favorite sources of yield and financing stopped feeling like a quiet corner of the market and started looking like a meaningful area of risk.
The Economy Softened, but the Shock Came from the Market’s Changing Expectations
The underlying U.S. economy was not collapsing in the first quarter, but it was clearly losing some momentum. Labor-market data and hiring trends weakened, while inflation remained above the Fed’s target even before oil surged late in the quarter. Reuters noted that falling job openings and hiring added to growth concerns just as energy prices reignited inflation worries.
The bond market reflected that change in expectations. The 10-year Treasury yield rose for a second straight quarter and finished around 4.31%, after briefly moving even higher during the quarter as investors reduced expectations for near-term Fed cuts. In a normal risk-off environment, bonds often provide more of a cushion. In 1Q26, that protection was more limited because the market feared inflation could reaccelerate.
Market Leadership Changed Fast
Energy and industrials led the quarter, while tech and financials struggled most. That fits the broader tone of the market. Energy benefited from the oil spike. Industrials held up better as investors favored more tangible, economically linked businesses. Technology, on the other hand, was hit from multiple directions at once: higher rates, war-driven uncertainty, AI disruption fears, and simple profit-taking after a huge multiyear run. Financials also struggled as investors worried about credit conditions, funding, and possible spillover from private credit stress.
This was especially important because large-cap technology has been so dominant in index performance. When those leaders falter, the broad indexes feel it quickly.
The Magnificent Seven Lost Their Aura
The Magnificent Seven remained one of the most important market stories of the quarter, but for the wrong reasons. The group’s index finished the quarter nearly 17% below its late-October 2025 high, a sharp reversal for the stocks that had been the market’s most dependable leadership engine.
The stock-specific damage was meaningful. Microsoft fell nearly 33% from its prior peak, Meta Platforms more than 26%, and even Nvidia — the poster child for the AI trade — slumped roughly 18% from when the tech trade began to sour. That pressure mattered not just because of the companies themselves, but because so much of the market’s prior strength had been tied to their leadership.
That point matters because the broader market’s recovery likely depends, at least in part, on whether mega-cap tech can regain its footing. When one-third of the index is tied closely to a handful of companies, market leadership is not just a side story. It is the story.
Three Questions for the Quarter Ahead
As we move into the second quarter, here are three of the biggest questions likely to drive markets:
1. Does the Iran War De-Escalate, or Does Oil Remain the Market’s Biggest Macro Variable?
If energy prices stay elevated, inflation pressure could remain stubborn and keep the Fed boxed in.
2. Was the Software Selloff Just a Valuation Reset, or the Start of a Broader Repricing in Enterprise Tech?
If AI-native tools continue to gain traction, investors may keep rethinking what deserves a premium multiple in software.
3. Does Private Credit Stabilize, or Do Liquidity Concerns Spread Further?
So far, policymakers are not calling it systemic, but markets are clearly paying closer attention.
Final Thought
The first quarter of 2026 was a reminder that markets can change character quickly.
A quarter that began with optimism around AI, earnings, and eventual Fed relief ended with investors debating war, oil, software disruption, private credit, and whether the market’s biggest winners had simply become too crowded. That does not mean the long-term investment case is broken. It does mean the path ahead may be bumpier than many expected just three months ago.
And in quarters like this, discipline matters far more than headlines.
