March ended with a powerful relief rally, but it did not change the bigger picture: the U.S. equity market spent most of the month under pressure from geopolitical risk, higher energy prices, tighter financial conditions, and a more cautious rate outlook.

On March 31, the S&P 500 jumped 2.91% to 6,528.52 on hopes that the U.S.-Iran conflict could de-escalate, yet the index still closed the first quarter in negative territory and recorded its weakest quarter since 2022.

The dominant March driver was the Middle East shock. Since the February 28 U.S.-Israeli strikes on Iran, investors have had to price in the risk of a prolonged disruption around the Strait of Hormuz, which handles roughly one-fifth of global oil and LNG flows. That pushed crude sharply higher, lifted gasoline above $4 per gallon in the U.S., tightened overall financial conditions, and favored energy over growth-sensitive sectors.

At the same time, renewed tariff uncertainty and the earlier AI-led pullback in mega-cap technology added a second layer of pressure to valuations.

Macro data in March offered only partial relief. February payrolls unexpectedly fell by 92,000 and unemployment rose to 4.4%, while February CPI came in at 2.4% year over year and core CPI at 2.5%, suggesting inflation had cooled before the latest oil shock. The Fed then held rates at 3.50%-3.75% on March 18 and kept a cautious tone, with officials signaling they still need clearer evidence that inflation is moving back to target.

By month-end, weaker JOLTS data showed hiring had dropped to its lowest level since the pandemic, reinforcing the view that growth is slowing even as inflation risks are rising again.

Traders will be watching the March jobs report on April 3, FOMC minutes on April 8, March CPI on April 10, the Fed’s Beige Book on April 15, the next FOMC meeting on April 28-29, and the advance Q1 GDP release on April 30.

The Senate Banking Committee is also expected to hold Kevin Warsh’s Fed chair hearing as soon as the week of April 13, while Q1 earnings season will begin to shape sentiment as investors test whether corporate guidance can absorb the energy shock.

Bullish scenario.

If de-escalation in the Middle East continues, oil extends its retreat from the roughly $103 Brent / $100 WTI area seen at the start of April, March payrolls stabilize after February’s weak report, and CPI does not confirm a broad second wave of inflation, the market can recover further. In that setup, resilient early earnings from banks and cyclicals would likely support a rebound toward the 6,700-6,850 area for the S&P 500, with large-cap tech, semiconductors, and industrials leading the move.

Base scenario.

The more likely near-term outcome is continued range trading. If oil remains elevated but not accelerating, economic data stay mixed, and earnings are solid but cautious on margins and guidance, investors may keep rotating rather than commit to a broad risk-on move. In that case, the Fed is likely to stay in wait-and-see mode into the late-April meeting, and the S&P 500 may spend most of the month in a 6,350-6,650 band. That would favor selective positioning in energy, quality financials, and defensive sectors, while keeping pressure on the most expensive growth names.

Bearish scenario.

If the Iran conflict re-escalates, the Strait of Hormuz remains materially disrupted, oil turns higher again, March CPI surprises to the upside, and Fed communication hardens further, the market could see another leg lower. Policy uncertainty around Fed leadership and trade headlines would add to the stress. Under that scenario, the S&P 500 could retest 6,150, and in a deeper risk-off move slide toward 5,950-6,050 as multiples compress and investors rotate aggressively into cash, Treasuries, and defensives.

The bottom line for April is straightforward

the market is no longer trading only on growth and earnings. It is trading on the interaction between oil, inflation, Fed credibility, and geopolitical headlines.

For traders, that means staying flexible and event-driven.

For investors and analysts, it means watching whether earnings guidance can hold up while macro and geopolitical volatility remain unusually high.
