Looking back, 2025 felt almost straightforward. Markets had a clear set of drivers and, more importantly, those drivers all pointed in the same direction. The Federal Reserve was expected to ease, artificial intelligence (AI) was driving a powerful growth narrative, and the economy refused to slow in any meaningful way. It created a feedback loop: lower rates supported valuations, AI justified those valuations, and resilient growth made the whole story believable.

That alignment is what made the rally so strong.

Fast forward to April 2026, and the picture is more complicated. The same themes are still there, but they no longer reinforce each other cleanly. Markets are now trying to work out whether these drivers are still tailwinds, or whether they are quietly turning into something else.

The Fed has Moved from Expected Support to Lingering Constraint

The biggest shift has come from the Fed. In 2025, markets were comfortable pricing in a steady path of rate cuts, even when policy itself remained tight. It didn't matter that financial conditions were restrictive; what mattered was the belief that relief was coming. That belief helped support equity multiples and risk appetite.

Today, that confidence has faded. The Fed has clearly moved into a holding pattern, with rates still elevated and policymakers showing little urgency to cut. Inflation remains sticky, with energy-driven pressures picking up again, and that has forced a more cautious stance.

Markets have adjusted accordingly. Expectations for rate cuts have been pushed out, reduced, or in some cases removed altogether. There is still a path to easing, but it is conditional: inflation needs to fall convincingly, or growth needs to weaken. Until then, the Fed is no longer providing the kind of support it once did. It is not quite a headwind, but it is no longer something investors can lean on.

AI has Evolved from Clear Narrative to Two-Sided Story

AI is a different story. It remains central to the market narrative, but the tone around it has shifted. In 2025, AI was almost entirely positive. It drove earnings expectations, justified high valuations, and fuelled a surge in capital spending. Investors were willing to look past short-term uncertainty because the long-term productivity story was so compelling.

That story hasn't disappeared, but it has become less straightforward.

By early 2026, there are signs that markets are reassessing both the timing and the distribution of AI's benefits. Some of the biggest AI-linked stocks have struggled this year, even as investment continues, highlighting a gap between expectations and delivery.

At the same time, AI is no longer just about upside. It is also creating uncertainty around disruption, costs, and whether current spending will translate into near-term returns. In practice, that means AI is still a structural tailwind, but in the short term it is contributing to volatility and dispersion rather than a steady upward push.

Growth is Holding Up, but Losing Breadth

That leaves growth, the third pillar of the rally. So far, it has held up. Earnings expectations remain solid, and markets have continued to push higher, supported by strong results and resilience in economic activity.

But beneath the surface, there are signs of strain. Geopolitical tensions have pushed oil prices higher, feeding into inflation and complicating the outlook. At the same time, analysts are warning that the market may be underestimating how these pressures could affect the broader economy.

There is also a growing concentration problem. A large share of earnings momentum is coming from a relatively small group of companies, leaving the broader market more exposed if leadership falters.

This matters because it changes the nature of the support. In 2025, growth was broad enough to underpin the market as a whole. In 2026, it is still there but it is narrower, more fragile, and more exposed to shocks.

What This all Means

Put all of this together, and the key difference between 2025 and 2026 becomes clear. Last year was defined by alignment. The Fed, AI, and growth all worked together, reinforcing the same bullish outcome. This year is defined by tension.

• The Fed is constrained by inflation and uncertainty.
• AI is both an opportunity and a source of disruption.
• Growth is holding up, but becoming more selective.

These forces are no longer moving in sync.

That does not mean the bull case is over. Far from it. AI still has the potential to drive a meaningful productivity cycle, growth remains positive, and the Fed could still ease if conditions allow. But the market no longer has the luxury of assuming that everything will fall into place.

Instead, it is entering a phase where those assumptions need to be tested.

The tailwinds that defined 2025 are still present, but in 2026, they are weaker, less reliable, and far more dependent on how events actually unfold. Markets are no longer being carried higher by a single, coherent story. They are being pulled between competing narratives, each of which needs to prove itself.

And that shift, from confidence to validation, is what will define this next phase of the cycle.
