US stock index futures edged higher on Tuesday as investors weighed tentative signs of de-escalation between Washington and Tehran against a macro backdrop that remains uneasy.

The mood turned more measured, as Washington moved to enforce a maritime blockade targeting Iran-linked traffic, while oil prices retreated from earlier highs on cautious optimism.

Nearly two dozen S&P 500 companies are due to report this week, including JPMorgan Chase, Wells Fargo, Citigroup, BlackRock and Johnson & Johnson, while the March producer price index is scheduled for release at 8:30 a.m. (ET) on Tuesday.

5 things to know before Wall Street opens

1. US equity futures pointed to a slightly stronger open after markets spent the start of the week repricing geopolitical risk.

S&P 500 futures up 0.2%, Dow Jones Industrial Average futures gaining nearly 100 points, or 0.14%, and Nasdaq-100 futures leading the advance with a 0.34% rise.

Investors are still balancing hopes of de-escalation with the reality that the US move to tighten pressure on Iran keeps the region, oil markets and global growth squarely in focus.

2.Earnings season is arriving at a delicate moment. The reporting calendar is heavy, and the timing could hardly be more important.

Reports from JPMorgan, Wells Fargo, Citigroup, BlackRock and Johnson & Johnson headline a week that includes nearly two dozen S&P 500 companies.

Results from the large banks, in particular, are likely to frame the wider debate over credit quality, deal activity and whether management teams are growing more cautious on the second half of the year.

Wells Fargo fell 0.8% in premarket trading, Citigroup slipped 0.6%, and Johnson & Johnson also edged lower, while BlackRock gained 0.6%.

JPMorgan, due on Tuesday, was little changed.

That uneven performance suggests investors are prepared to reward resilience, but are not yet willing to pay up simply for scale or defensive positioning.

3. Inflation remains the market’s other problem. Even with the Middle East dominating headlines, inflation has not gone away.

The producer price index is due on Tuesday morning, just days after data showed the biggest increase in consumer prices in almost four years, reinforcing concerns that any easing by the Federal Reserve would be driven by growth worries rather than a clean victory over inflation.

That distinction matters because rate cuts linked to economic stress rarely deliver the same lift to equities as cuts made in a benign disinflationary setting.

Fed officials are also due to speak through the day, including Austan Goolsbee, Susan Collins, Michael Barr, Tom Barkin and Anna Paulson.

4. Stock moves reflect a market caught between risk and opportunity.

The premarket tape showed how selective investors have become.

Airlines moved higher after a Reuters report said United Airlines chief executive Scott Kirby pitched a potential combination with American Airlines to US officials in late February.

United rose 1.5%, while American climbed 4.3%, underscoring how quickly merger speculation can outweigh broader concerns about fuel costs and travel demand.

5. The next move depends on whether geopolitics or guidance leads.

For now, Wall Street is trying to decide which narrative deserves the larger premium: war risk or earnings resilience.

Deutsche Bank said hopes for further talks support expectations of de-escalation even as the US blockade begins, a reminder that diplomacy and military pressure are now moving in parallel rather than in sequence.

That leaves investors watching two things above all else over the next few sessions: whether crude stays contained enough to stop another inflation scare, and whether corporate guidance is strong enough to pull attention back towards fundamentals.
