The Top Line
A war between the U.S. and Iran has rattled markets for four weeks — but Monday brought a glimmer of hope when President Trump announced a five-day pause in military strikes, citing talks with Tehran, and stocks surged. Iran quickly denied any talks were happening, so today's big question is whether the optimism holds or reverses just as fast.
We are operating in a transitional/mixed macroeconomic regime, characterized by resilient above-trend growth colliding with a stagflationary energy shock of unprecedented modern scale. The U.S.-Iran conflict—now in its fourth week—has driven Brent crude to peaks above $113 per barrel before Monday's partial ceasefire signal, producing the largest oil supply disruption on record according to the IEA, and forcing the Fed to simultaneously confront upside inflation risk and downside growth risk. The FOMC held rates at 3.50–3.75% on March 18th, raising its 2026 PCE inflation forecast to 2.7% while keeping GDP projections at a solid 2.4%, acknowledging that the Middle East implications for the U.S. economy are "uncertain"—a rare explicit geopolitical qualifier in Fed language. Today's flash S&P Global Composite PMI of 51.4 (down from 51.9 in February) confirms the economy is still expanding, but the manufacturing sub-index printing 49.8—contractionary territory—signals that the energy shock and supply chain disruption are already biting the goods-producing sector with cost inflation at a 31-month high.
Inflation
Prices were already rising faster than the Federal Reserve (the U.S. central bank that sets interest rates) would like — and now a war-driven spike in oil prices is pushing them higher. Gasoline and energy costs feed into almost everything: shipping, manufacturing, food. The Fed held interest rates steady last week and signaled it still expects to cut rates once this year, but only if inflation doesn't get worse. The latest business survey data released this morning showed that manufacturers are reporting the highest cost pressures in nearly three years, driven by both oil and ongoing tariffs. If those costs land on your grocery bill and at the pump — and they will — the Fed may have no room to lower rates at all.
Key Takeaway
Higher gas prices are feeding into broader inflation — interest rates are likely to stay elevated longer than hoped.
The inflation picture has materially deteriorated since February, and the trajectory is firmly higher in the near term. Headline CPI for February 2026 printed at 2.4% year-over-year—a reading that predates the energy shock entirely. The Fed's own March SEP raised the 2026 PCE inflation forecast to 2.7% (headline and core alike, up 30 basis points from December projections), with Chair Powell explicitly citing tariff-driven goods inflation and now layering in the oil supply shock as compounding pressures. The concern is not that current readings are alarming in isolation; it is that the energy shock is a new and unquantified variable atop already-sticky services inflation, and March CPI/PCE data—due in April—will be the first real look at the combined impact.
Services inflation has been the persistent core problem throughout 2025-2026, with shelter and healthcare keeping core measures above target even as goods disinflation provided partial offset. That goods disinflation is now reversing sharply: today's flash PMI showed manufacturing input cost inflation at a 31-month high, attributed to both tariff pass-through and energy-driven supply chain disruptions. Powell acknowledged in his March 18th press conference that he views the tariff price impact as a "one-time" level shift rather than a sustained inflationary process, and that oil shocks are historically looked through. However, he was explicit that the committee is "well-aware of the history" and is vigilant against inflation expectations becoming unanchored—a signal that a second energy-shock in two years does raise the credibility risk threshold.
Market-implied inflation expectations, measured through TIPS breakevens, have been rising steadily since the conflict began, and fed funds futures have dramatically repriced: before the Iran war, markets expected two cuts in 2026. Today, market pricing has converged toward one cut at most, with some traders beginning to price a hike as a tail scenario. The next critical data point is April's CPI release, which will capture March energy prices in full. If headline CPI surges above 3.0% while core accelerates toward 3.0%, the Fed's patient posture becomes increasingly difficult to sustain.
Key Takeaway
The Fed is explicitly data-dependent with a hawkish lean, holding at 3.50–3.75% with one cut projected for 2026. The March energy shock has not yet shown up in official inflation data, but it will—making April CPI the defining release of the quarter. Financial conditions have tightened materially since the conflict began, driven by elevated yields and elevated uncertainty premiums.
Risk and Positioning
The market's fear gauge — called the VIX — closed Monday at 26, still well above the calm range of 13–14 we saw before the war began. That means investors remain anxious despite the rally. Think of it like a sunny afternoon with a storm watch still in effect: the skies cleared up, but meteorologists are still watching radar. Gold — a classic "safe harbor" that people buy when they're worried — fell sharply on Monday as some investors moved back into stocks. But credit markets (where companies borrow money) are still showing stress, with lenders charging significantly more to less-creditworthy borrowers — a sign that professionals aren't fully convinced the danger is over. Iran denied the talks Trump described, and fighting continued overnight.
Key Takeaway
Markets relaxed yesterday, but the underlying nervousness hasn't gone away — one bad headline could reverse the rally quickly.
Risk sentiment shifted decisively to risk-on during Monday's session following Trump's Truth Social post announcing a five-day pause on strikes against Iranian energy infrastructure and citing "productive" talks. Equities rallied broadly, with the S&P 500 gaining 1.15%, the Dow 1.38%, and the Russell 2000 surging 2.29%—the latter's outperformance is notable, as small caps had been among the most battered in the war-driven selloff. Nine of eleven S&P sectors finished in positive territory, with only two laggards in a clear broad-based recovery. However, context demands discipline: the VIX closed at 26.15—firmly in elevated-fear territory (historically, sustained readings above 25 correspond to elevated recession probability pricing)—and Iran's Fars News Agency denied any talks occurred, leaving the geopolitical situation highly ambiguous heading into Tuesday's session.
Equity valuations have repriced meaningfully since the conflict began, with the S&P 500 having declined approximately 10% from its all-time high before Monday's partial recovery. The index broke below its 200-day moving average—its first such breach since May 2025—flagging technical damage that will take sustained positive catalysts to repair. Credit markets have widened materially, with high yield spreads expanding sharply since late February; per FRED data through March 19, the ICE BofA HY OAS had been pushing toward 400+ basis points over Treasuries, reflecting genuine recessionary risk pricing. The expansion in credit spreads—in contrast to equities' sharp one-day recovery—is an important divergence: credit markets are pricing more persistent stress than the equity bounce implies.
Safe-haven positioning sent a mixed signal on Monday. Gold fell sharply—by as much as $200 per troy ounce during the session—as risk appetite recovered, while the dollar also declined approximately 55 basis points as oil fell. Treasury demand was complicated: the 10-year yield fell 4 basis points on the day, consistent with a relief rally, but remains 38 basis points higher than four weeks ago as cumulative inflation fears have structurally repriced the long end. The contradiction at the center of markets: equities rallied hard on ceasefire optimism, but yields remain elevated and credit spreads remain wide, suggesting institutional investors are not yet confident that the inflationary damage from the energy shock is over.
Key Takeaway
Implied volatility at 26.15 VIX remains approximately double the pre-conflict levels near 13-14. Credit spreads signal persistent stress despite Monday's equity rally. The core risk is that the ceasefire signal proves ephemeral—Iran denied talks—producing a violent reversal. Until WTI sustains below $85, inflation risk and Fed credibility risk remain elevated.
Sector and Cross-Asset Analysis
Oil and gas companies have been the big winners of 2026 — up over 30% this year as oil prices soared — but on Monday they gave back ground as crude oil prices fell sharply when Trump suggested a peace deal was possible. Almost every other part of the market rallied: smaller U.S. companies, tech, and consumer businesses all bounced strongly, as investors bet that a ceasefire would mean lower energy costs and a healthier economy. Gold dropped significantly — over $100 per ounce — because gold typically falls when people feel safer. European stocks, by contrast, barely moved, reflecting more skepticism overseas about whether a deal is real. The Strait of Hormuz — the narrow waterway that carries about 20% of the world's oil — remains closed, and reopening it is the single biggest lever for energy prices.
Key Takeaway
Oil stocks retreated as peace hopes grew — almost everything else rallied, but the gains depend on a deal that isn't confirmed yet.
Energy has been the defining sector of 2026, gaining approximately 5.9% since the U.S.-Iran war began on February 28th and a remarkable 31.8% year-to-date—a performance that has no close peer among S&P 500 sectors and reflects the structural oil supply disruption. However, Monday's session was a reversal trade: energy underperformed as WTI crude fell from above $98 to approximately $91-92 per barrel on Trump's ceasefire announcement, while cyclicals, small caps, and interest-rate-sensitive sectors led the recovery. Technology and communication services, which had been the primary victims of the Iran shock's valuation compression and rising rate fears, saw sharp recoveries. The Russell 2000's 2.29% gain versus the S&P's 1.15% is a textbook short-covering and rotation signal—small caps are more sensitive to domestic growth expectations and less hedged, making them a leading indicator of risk appetite shifts.
Cross-asset dynamics on Monday were dramatic: oil down sharply (WTI near $91 from $98+ Friday), gold down significantly (from recent multi-year highs near $4,575 to the $4,366 range), the dollar down 55 basis points, and equities up. This is the classic "geopolitical fear unwind" pattern—energy and gold were the crisis hedges, and they reversed as the crisis signal softened. International markets offered a counterpoint: European stocks finished lower on Monday, with the FTSE 100 down 0.24%, as markets there were skeptical of the diplomatic signal and continue pricing ongoing shipping disruption through the Strait of Hormuz. The divergence between U.S. and European equity performance reflects different energy-import exposures and different assessments of the ceasefire credibility.
Credit market behavior warrants continued attention. High yield spreads have widened significantly over the past month, with energy sector high yield credits a notable exception (buoyed by oil prices). Investment grade spreads have also widened, though less dramatically, suggesting that systemic credit stress is elevated but not yet at crisis levels. The advance/decline picture was broadly positive on Monday, with 9 of 11 sectors advancing and the new-lows list shrinking from Friday's 274 new 52-week lows to a more moderate level—a constructive but not definitive internal signal. Until the S&P 500 reclaims its 200-day moving average on a closing basis, the technical posture remains cautious.
Key Takeaway
Energy's 31.8% YTD gain makes it the undisputed 2026 sector champion, but Monday saw a sharp reversal as ceasefire optimism pressured crude. The recovery was broad, with small caps leading, but leadership is fragile—built on diplomatic signals that Iran has not confirmed. Technology and international markets present the clearest binary around conflict resolution.

Week Ahead
This week's marquee release is Friday's University of Michigan Consumer Sentiment final reading for March—a critical gauge of household confidence under oil-shock conditions. Thursday brings weekly jobless claims and durable goods orders. Conference Board Consumer Confidence is scheduled for March 31st. No FOMC speakers are expected this week given the recent meeting; the next FOMC decision is May 6-7, with Chair Powell's term expiring May 15th, adding institutional transition risk to the policy backdrop.
What We're Watching
Monetary Policy: Fed on Hold as Stagflation Risk Rises
The FOMC held at 3.50–3.75% on March 18th, projecting one cut in 2026 with PCE inflation revised to 2.7%. The May 6-7 meeting is the next decision point; an oil-driven CPI surge above 3.0% could eliminate the remaining cut and introduce hike optionality. Powell's term expires May 15th, adding Fed transition risk.
Rates & Fixed Income: Yield Curve at an Inflection Point
The 10-year yield trades near 4.35% after reaching multi-month highs above 4.42% during last week's peak fear. The 2s10s spread remains positively sloped, consistent with late-cycle dynamics. Duration is a two-sided bet: ceasefire resolution drives yields lower, while inflation reacceleration pushes the 10Y toward 4.75%.
Equities: Binary Around Ceasefire Credibility
Monday's 1.15% S&P rally is built on diplomatic optimism that Iran has publicly denied. A re-escalation scenario targets the 6,200–6,300 range on SPX (Wells Fargo's stated worst-case), while confirmed de-escalation and crude returning below $80 targets a recovery through 6,700. Quality, energy, and defensive positioning remain prudent hedges.
Key Risks: Iran Denial, Oil Persistence, and Fed Credibility
Iran's Fars News Agency denied any talks with the U.S., directly contradicting Trump's announcement. If conflict re-escalates and Brent re-tests $110+, stagflationary pressure forces the Fed toward a hawkish hold or eventual hike, compressing equity multiples while raising recession probability. Saudi Arabia and UAE proximity to the conflict is an additional tail risk.
The Bottom Line
Yesterday's rally was real, but it rests on a peace signal that Iran publicly rejected — and overnight news shows fighting is continuing. Today's session will likely see early pressure as markets digest Iran's denial, with direction determined by whatever diplomatic developments emerge from the five-day pause window Trump announced.
Treasuries are consolidating near 4.35% on the 10-year after hitting a multi-month high of 4.39% on Friday, with the ceasefire signal providing modest relief but not resolving the underlying inflation-risk premium baked into the long end. Monday's equity rally was substantial and broad, but the session opened on a binary diplomatic event that Iran has not confirmed—Tuesday's trade will hinge on whether overnight developments reinforce or reverse the de-escalation narrative. The S&P 500 faces immediate technical resistance near its 200-day moving average in the 6,600-6,650 range; a sustained close above that level would be a meaningful technical signal. Energy and gold should continue to reverse if ceasefire optimism holds, while technology, consumer discretionary, and small caps will lead any sustained recovery trade—but position sizing must account for the possibility that Iran's denial of talks re-ignites the risk-off trade within hours.
