Markets Watch: Fed Decision Dominates as Iran Conflict Keeps Oil Elevated; Micron and Lululemon in Focus

U.S. equity futures moved higher as markets awaited a Federal Reserve interest rate decision that arrives while fighting in Iran continues to unsettle energy markets. Brent crude eased but remained above $100 a barrel amid concerns that disrupted supplies will sustain inflationary pressures and could delay prospective Fed rate cuts. Memory-chip maker Micron is set to report after the bell, and Lululemon provided soft annual guidance that disappointed analysts.

Key Points

  • U.S. equity futures rose ahead of a Federal Reserve interest rate decision, with Dow futures up 258 points, S&P 500 futures up 34 points, and Nasdaq 100 futures up 159 points as of 04:18 ET (08:18 GMT).
  • Brent crude fell 1.3% to $102.10 a barrel and U.S. West Texas Intermediate dropped 2.3% to $93.25 a barrel, but oil remains significantly above pre-war levels, contributing to higher gasoline prices in the U.S.
  • Micron reports after the close with a previously issued fiscal second-quarter adjusted profit guide of $8.42 a share, plus or minus $0.20, while Lululemon provided 2026 revenue and profit guidance below analysts’ estimates.

U.S. stock-index futures were trading higher early Wednesday as investors prepared for a Federal Reserve interest rate announcement that comes against the backdrop of continued hostilities in Iran. The conflict has kept energy markets on edge and could complicate the Fed's path on policy amid rising concerns about inflation.

By 04:18 ET (08:18 GMT) Wednesday, futures tied to the main U.S. averages showed modest gains. The Dow futures contract was up 258 points, or 0.5%, S&P 500 futures had risen 34 points, or 0.5%, and Nasdaq 100 futures were higher by 159 points, or 0.6%.


Market backdrop and geopolitics

Equities had advanced in the previous trading session as investors reacted to a string of developments in Iran. Analysts at Vital Knowledge noted that reports of the deaths of two senior Iranian leaders, together with the high-profile resignation of a Trump administration official who protested U.S. strikes on Iran, fostered some hope that a ceasefire could be forthcoming.

Despite those signals, the strategic Strait of Hormuz remains at the center of market anxiety. The waterway, through which about one-fifth of the world’s oil shipments pass, continues to face threats of Iranian strikes on vessels. Efforts by President Donald Trump to rally international support to reopen the strait have largely failed, and uncertainty persists about when U.S. bombardments might be scaled back. The president reiterated on Tuesday that the war may end soon, but similar optimistic statements since the start of the joint U.S.-Israeli assault on Iran in late February have not yet produced a ceasefire.


Oil prices ease but stay elevated

While some short-term relief entered markets, oil prices remain well above pre-conflict levels. Brent crude, the global benchmark, fell 1.3% to $102.10 a barrel, and U.S. West Texas Intermediate crude dropped 2.3% to $93.25 a barrel. The pullback came in part as Iraqi crude exports resumed by pipeline from the Kirkuk fields to Turkey’s Ceyhan port, easing some supply tightness.

Nonetheless, the overall price backdrop is tighter than it was before hostilities escalated. Higher crude is already showing through to pump prices in the United States; gasoline costs have climbed to their highest levels since October 2023. For consumers, rising fuel costs are likely to be an important consideration for household budgets and could factor into voter concerns ahead of November. For the broader economy, elevated energy prices are a direct input into inflation measures, making the persistence of higher oil a salient variable for policymakers.

The U.S. military has continued its strikes on Iranian targets. On Tuesday, Central Command reported the use of 5,000-pound bombs along Iran’s coast near the Strait of Hormuz in operations aimed at degrading sites that house cruise missiles capable of targeting ships traversing the strait. Political pressure appears to be mounting within President Trump’s own Republican Party for an off-ramp from the confrontation, but the U.S. has shown limited signs of de-escalation to date.


Federal Reserve decision and the path for rates

Against this uncertain energy and geopolitical backdrop, the Federal Reserve is set to announce its latest interest rate decision at the conclusion of a two-day policy meeting. Markets generally expect the central bank to hold rates steady as policymakers assess both the trajectory of inflation and recent data that point to potential softness in the labor market.

All eyes will be on the post-decision press conference with Fed Chair Jerome Powell, who is due to step down from the helm of the central bank in May. That briefing could provide early insight into how Fed officials view the impact of the Iran conflict and the associated oil-price shock on inflation and on the timing of future rate moves.

Before the conflict erupted, many investors had been penciling in at least one rate cut later in the year, perhaps in the second half. As the war has kept oil prices elevated, analysts at ING warned that the Fed might signal a postponement of cuts if it judges that inflationary pressures will be prolonged by the conflict.


Corporate news: Micron’s earnings and Lululemon’s guidance

In corporate earnings, memory-chip manufacturer Micron Technology is scheduled to report results after the closing bell. The company provided a confident second-quarter adjusted profit outlook in December, forecasting $8.42 a share, plus or minus $0.20, which was nearly double analyst expectations cited by Reuters at that time. Micron’s upbeat guidance was driven by elevated memory chip prices amid ongoing supply constraints.

The firm’s products are central to data-center infrastructure, and the surge in investment by major technology companies into artificial intelligence capabilities has translated into heightened demand for high-end memory modules. Micron’s management told investors last year that tightness in the memory market is likely to persist beyond 2026 and that the company expected to satisfy only half to two-thirds of demand from several key customers.

Given that dynamic, investors will be parsing Micron’s report for signs of how supply, pricing and demand are evolving, particularly in relation to AI-driven data-center spending. Results and commentary may also influence sentiment across chipmakers and suppliers tied to memory markets.

Meanwhile, Lululemon Athletica’s shares slipped in premarket trading after the retailer issued annual revenue and profit guidance for 2026 that fell short of analysts’ expectations. The company projected annual revenue in a range of $11.35 billion to $11.50 billion, compared with LSEG consensus expectations of $11.52 billion. Annual adjusted profit was guided to $12.10 to $12.30 per share, also below Wall Street projections.

Lululemon said it expects to offset almost all costs arising from U.S. import tariffs as it focuses on securing more full-price sales. The company continues to contend with a prolonged search for a new chief executive, a slowdown in consumer spending, and rising competition. The retailer also added a former head of Levi Strauss to its board as it faces the prospect of a proxy contest.


Investor takeaways

Investors heading into the Fed decision face competing crosscurrents. On one hand, the central bank is widely expected to pause on rate moves while assessing incoming data. On the other hand, the Iran conflict has tightened energy markets, keeping a key input to inflation elevated and increasing the risk that rate cuts penciled in for later this year could be delayed.

Corporate earnings this week, particularly Micron’s report and Lululemon’s guidance, add another layer to market positioning. Micron’s exposure to data-center memory demand ties it directly to the AI investment cycle, while Lululemon’s results highlight consumer discretionary pressures and the influence of trade costs on retail margins.

Traders and portfolio managers will be looking to Powell’s remarks for the Fed’s near-term read on these developments and to company results for signals on demand and pricing conditions across technology and consumer sectors.

Risks

  • Prolonged hostilities in Iran could sustain higher oil prices, which would put upward pressure on inflation and complicate the Federal Reserve’s timeline for potential rate cuts - impacting energy and broader inflation-sensitive sectors.
  • Uncertainty over how the Fed will interpret the inflationary impact of the Iran conflict means policymakers may delay cuts that investors had expected later in the year, affecting fixed-income markets and interest-rate sensitive equities.
  • Corporate-level risks include tighter-than-expected supply dynamics in the memory-chip market or weaker-than-expected consumer spending; these could influence technology suppliers and consumer discretionary retailers respectively.
