Stocks Turn Lower as Oil Surges and Hot Inflation Data Raise the Stakes for the Fed

Tuesday’s close gave investors a real reason to think the market might be finding firmer footing. The S&P 500 rose 0.2%, the Dow added 0.1%, and the Nasdaq gained 0.5%, marking a second straight advance even with Brent crude closing above $103 a barrel. That was a meaningful change from the earlier phase of the conflict, when higher oil and weaker stocks were moving almost hand in hand.
That calmer setup did not last long on Wednesday. The session began with hopes that Iraq’s agreement with Kurdish authorities to resume some exports through Turkey’s Ceyhan route might take some pressure off crude, but those hopes were quickly overwhelmed by a fresh escalation after attacks on Iran’s South Pars field and new threats against Gulf energy infrastructure. By late morning, Brent had jumped above $108 and U.S. crude was back near $98, while the Dow, S&P 500, and Nasdaq were all trading lower.
At the same time, inflation added another layer of pressure. February producer prices rose more than expected, with headline PPI up 3.4% from a year earlier, reinforcing the idea that inflation was already running hot before the latest energy shock hit. That leaves the Federal Reserve in an even tighter spot ahead of its afternoon decision, with markets expecting no change in the 3.50% to 3.75% target range but watching closely to see whether policymakers still signal even one cut this year. Micron’s earnings after the close add another important catalyst, especially for investors still leaning on the AI trade for leadership.
Stock of Interest Today: Affirm Holdings (AFRM)
Affirm stands out because it offers something the broader market does not have much of right now: a company-specific growth story with fresh operating targets attached to it. As of 11:12 a.m. Eastern, MarketBeat showed the stock around $48.20, while the company’s fiscal 2026 outlook calls for revenue of $4.09 billion to $4.15 billion and adjusted operating margin of 27.4% to 28.1%. In a market dominated by oil spikes, inflation anxiety, and Fed risk, those are unusually concrete numbers for investors to anchor to.
The operating momentum underneath that outlook is what gives the story more weight. Affirm reported active merchants up 42% to about 478,000, while active Affirm Card consumers rose 121% to 3.7 million, evidence that the company is widening its merchant base and deepening engagement at the same time. That does not remove execution risk, but it does make the case more substantial than a simple valuation argument.
There is also still a clear upside case if execution holds. MarketBeat’s analyst compilation shows a 12-month consensus target of $84.36, which is well above the current trading area and helps explain why Affirm can continue drawing attention even when the broader tape is being pushed around by oil, yields, and policy expectations.
Current price: $47.56
Analyst target: $84.36 consensus
Five Market Themes
This market is no longer being pulled by a single narrative. What looked like a straightforward relief story early in the day has turned into a more unstable mix of energy risk, hotter inflation, central-bank uncertainty, and selective company-level leadership. That is what makes the next few hours more important than the last two sessions.
1) Stocks can handle high oil better than they can handle a new energy-infrastructure escalation
Tuesday’s rally suggested investors were starting to tolerate expensive oil as long as the shock was not getting worse. Wednesday’s reversal showed the limits of that resilience. Once the market had to contend with direct attacks on major Iranian energy facilities and threats to more Gulf infrastructure, the rebound lost momentum quickly.
2) The Iraq-Ceyhan restart still matters, but it is now a partial offset rather than the main story
The Baghdad-KRG deal remains important because it restores some northern export capacity through Turkey and offers a route that avoids the Strait of Hormuz. But Reuters reported that Iraq’s supply relief is still limited, with production at roughly one-third of pre-crisis levels and tanker traffic through Hormuz still heavily restricted. In other words, the restart helps, but it does not come close to resolving the broader supply shock.
3) The Fed decision matters less for the hold than for the projections
The Fed is still widely expected to leave rates unchanged this afternoon, but that is not where the real tension sits. The bigger question is whether policymakers still show one cut for 2026 or shift more hawkishly after hotter producer inflation and another sharp move higher in oil. Reuters reported that investors are increasingly focused on the updated projections and Powell’s language, because the market now has to think about slower growth and stickier inflation at the same time.
4) Australia’s rate hike is still one of the clearest signs that policy paths are diverging
The Reserve Bank of Australia raised its cash rate by 25 basis points to 4.10% in a 5-4 vote, becoming the first major central bank to tighten in direct response to the latest oil shock. That does not mean the Fed will follow, but it does reinforce the idea that the global policy outlook is fragmenting again, with some economies facing much more immediate inflation pressure than others.
5) The dollar and Treasury yields are firming again, which tells you the haven trade is not finished
Earlier in the day, there were hints that the dollar’s war-driven bid might be fading. The latest move points the other way. Reuters reported that the dollar ticked higher after the inflation data, while the 10-year Treasury yield rose to about 4.226%, and AP reported the benchmark yield at 4.22% late in the morning. That combination suggests investors are leaning back toward defensiveness as they wait for the Fed.
Bottom Line
The market is in a more difficult position than it appeared to be at the open. What began as a story about easing oil and a possible third straight day of gains has turned into a much messier test of how investors handle rising crude, hotter inflation, and a Fed that may have less room to sound reassuring. That leaves policy guidance as the key pivot for the afternoon. Until then, the cleaner stories are still the ones driven by company execution rather than macro guesswork, which is why Affirm remains one of the more interesting names on the board today.
