Investors enter a packed calendar as stalled negotiations between the U.S. and Iran keep the Strait of Hormuz effectively closed, while corporate earnings from major technology companies, several central bank rate decisions and the first U.S. GDP reading for the year all converge to influence asset prices. Energy-driven inflation risks have tempered expectations for near-term rate cuts by the Federal Reserve, even as a broad swath of S&P 500 firms report results that could sustain recent equity momentum.

Key Points

  • Stalled U.S.-Iran talks and the closure of the Strait of Hormuz are keeping crude prices elevated and creating an inflation risk backdrop that could affect energy-sensitive sectors such as transportation, manufacturing and consumer goods.
  • A busy corporate earnings week includes roughly 35% of S&P 500 companies, with hyperscalers like Alphabet, Microsoft and Meta in focus as markets watch AI-related spending and its impact on growth and margins, particularly in the technology sector.
  • Central bank decisions - led by the Federal Reserve, plus the ECB, BOE and BOJ - and the U.S. first-quarter GDP and PCE inflation data are likely to drive market positioning and influence assets across equity, bond and currency markets.

Expect a frenetic week on markets as geopolitical friction, a flood of corporate earnings and a series of central bank meetings collide with important economic releases. Investors must weigh developments around stalled U.S.-Iran negotiations and the resultant disruption of a key oil transit route against quarterly corporate results - notably from major technology firms - as well as upcoming policy decisions and growth data.


1) Negotiations stall as Strait of Hormuz remains a flashpoint

Headlines around talks between the United States and Iran are likely to continue dominating investor attention after recent signals suggested the negotiations have reached an impasse. Over the weekend, President Donald Trump called off plans to send U.S. negotiators to Pakistan for fresh discussions following a brief visit by Iran's foreign minister to Islamabad. Mr. Trump said he will wait until Tehran "calls" him, arguing that the United States holds the majority of leverage in the talks.

An Axios report on Monday said Iran had offered a new proposal to the U.S. that would reopen the Strait of Hormuz and end the war - but only if discussions over Tehran's nuclear program were deferred to a later stage. That report helped to briefly moderate a spike in oil prices, yet crude remains substantially higher than pre-war levels largely because the strait is effectively closed.

The Strait of Hormuz - a narrow waterway off Iran's southern coast - handles roughly a fifth of the world's oil. The interruption or extended disruption of flows through that passage has prompted warnings from market observers that weekslong constraints could carry serious consequences for the global economy.


2) A torrent of corporate reports, with technology in focus

Beyond geopolitics, the corporate calendar will be a central force on market direction as earnings season ramps up. Telecommunications group Verizon is scheduled to report before the opening bell on Monday, and roughly 35% of companies in the S&P 500 are set to publish results during the week.

Analysts have pointed to a solid start to Q1 reporting season. "[S]tocks aren’t just a geopolitical story. Q1 reporting season has been solid thus far, with the S&P set for a sixth straight quarter of double-digit earnings growth, while enthusiasm towards the tech sector has also made a notable resurgence," Michael Brown, Senior Research Strategist at Pepperstone, wrote in a note.

Market participants will be watching a string of mega-cap names that have invested heavily in artificial intelligence capabilities. Google-owner Alphabet, software giant Microsoft and Instagram-parent Meta are among the large-cap companies whose results may shed light on how spending on AI is translating into revenue and margin dynamics. Those AI investments have been central to the so-called AI trade, a major bet on an emerging technology theme that helped sustain market momentum despite the headwinds stemming from the Iran conflict. Equity indices have rallied this month and recorded new highs.


3) The Federal Reserve decision and its context

Policymakers' actions and commentary will also be scrutinized closely, with the Federal Reserve's meeting standing out on the calendar. The Fed concludes a two-day gathering on Wednesday and is widely expected to leave borrowing costs unchanged.

Market expectations for near-term rate cuts were pared back following the Iran war's outbreak in late February, when the conflict triggered an energy shock that could feed inflation pressures in multiple countries. That shift in the inflation outlook has made officials and market participants more cautious about predicting imminent easing.

Some analysts contend that a pause by the Fed could itself prove supportive for U.S. assets, particularly if other major central banks move toward tightening. Meanwhile, questions about the central bank's leadership linger. Fed Chair Jerome Powell is scheduled to step down from the helm in May but has not confirmed whether he will relinquish his position on the rate-setting committee. President Trump's nominee to replace Powell, former Fed Governor Kevin Warsh, has not yet been confirmed. A potential hurdle was reduced last week when the Justice Department said it would close an investigation into Powell relating to renovation costs at the Fed's headquarters.


4) Other major central bank meetings lined up

Alongside the Fed, central banks in Europe, the U.K. and Japan will deliver decisions that could add clarity to the global policy trajectory as the repercussions of the Iran conflict unfold. The European Central Bank is broadly expected to maintain its deposit rate at its meeting on April 30, with markets anticipating a further increase in June as authorities attempt to counter inflationary pressure linked to the war.

The Bank of England is similarly seen by many as likely to stand pat on rates at its Thursday meeting while it gauges the impact of higher energy prices and geopolitical risks on inflation and growth. Nevertheless, some investors expect rate increases later in the year if inflation proves persistent.

In Asia, the Bank of Japan is widely expected to keep interest rates unchanged at its April 28 meeting. Still, officials could adopt a firmer tone should inflationary pressures intensify amid rising oil prices.


5) Key U.S. economic releases: Q1 GDP and the PCE price index

The economic data flow is also busy, with the initial estimate of U.S. GDP for the January-March period among the most closely watched figures. The world's largest economy is projected to have expanded by 2.2% in the first quarter, up from a 0.5% rise in the final three months of 2025.

Pepperstone's Michael Brown cautioned that the headline growth figure will be "artificially boosted" by the unwinding of the effects of a record-long government shutdown that occurred during the fourth quarter. That caveat suggests that the underlying momentum may be less robust than the headline number indicates.

Also due is the personal consumption expenditures (PCE) price index for March, which is one of the Federal Reserve's preferred measures of inflation. That data point will be used by market participants and policymakers alike to assess whether price pressures are intensifying or easing, and how such trends should shape future monetary policy decisions.


What this means for markets and key sectors

Multiple forces are now converging. The closure of the Strait of Hormuz and its implications for oil supplies have kept energy markets tight, supporting higher crude prices that in turn raise the risk of broader inflationary pressure. That dynamic affects sectors sensitive to energy costs, including transportation, manufacturing and consumer goods.

Technology sector sentiment is a countervailing force: strong Q1 earnings across major tech firms - particularly those deploying large AI budgets - have underpinned equity strength and prompted a rally in headline indices. Financial markets will be closely watching corporate reports to see whether AI-related investments continue to deliver growth and sustain investor enthusiasm.

Monetary policy outcomes will remain a dominant influence. A Fed hold would align with tempered expectations for cuts, while policy signals from the ECB, BOE and BOJ could shift cross-border asset flows and influence currency and bond markets.


Bottom line

This week represents a concentrated test of market sentiment. Geopolitical developments tied to U.S.-Iran negotiations and the status of the Strait of Hormuz create an oil-price and inflation risk backdrop. Against that are corporate earnings - led by large technology names fueling the AI trade - which have helped push indices to new highs. Central bank decisions and the U.S. first-quarter GDP and PCE readings will provide further signals on how policymakers and investors should respond as these layered risks and opportunities unfold.

Risks

  • Prolonged disruption of shipping through the Strait of Hormuz could sustain higher oil prices and fuel broader inflation, posing risks for sectors dependent on energy inputs, including transportation and manufacturing.
  • An upward surprise in inflation measures such as the PCE index could dampen expectations for near-term Fed rate cuts and increase volatility in interest-rate sensitive assets including bonds and rate-sensitive equities.
  • If corporate reports fail to match elevated expectations for AI-driven revenue or margin gains from major technology firms, equity indices that have recently hit record highs could face downward pressure, affecting market sentiment.
