This weekly recap covers 13 April to 19 April 2026. As always, market pricing data runs through Friday's close, while the weekend matters for the setup into the following week. The previous week had ended with a relief rally built on the ceasefire announced on April 7 and a sharp drop in oil below $100. This week carried that momentum further — and then some. By Friday, the S&P 500 had risen 4.5% on the week to a record close, completing a third consecutive week of gains, its longest such streak since Halloween. Oil reversed dramatically: WTI crude posted its worst weekly performance since April 2020, falling more than 16% after Iran declared the Strait of Hormuz open to commercial traffic. The result was a week that looked genuinely transformative on the surface, but still carried political fragility underneath.
Quick highlights
- Monday extended the rebound with resilience: the S&P 500 jumped 1.02% to 6,886.24, the highest close since before the war began. The Dow added 0.63% to 48,218.25 and the Nasdaq gained 1.23% to 23,183.74. Stocks had initially dipped before recovering after Trump said, "We've been called by the other side."
- Tuesday extended the rally as second-round talk prospects firmed: the S&P 500 gained 0.80% to 7,022.95, the Nasdaq advanced 1.59% to 24,016.02. Live Nation fell sharply after a federal jury found the company held an illegal monopoly over the ticketing market.
- Wednesday saw back-to-back record closes: the S&P 500 and Nasdaq hit all-time highs as markets traded as though the war were already over. The IMF released its World Economic Outlook, cutting the 2026 global growth forecast. Madison Air Solutions debuted on the NYSE in the largest U.S. industrial IPO since 1999.
- Thursday was headlined by Netflix earnings: the streaming giant beat Wall Street revenue estimates for Q1 with $12.25 billion, up 16% year on year. Shares fell 9% in after-hours trading on softer forward margin guidance and the announcement that co-founder Reed Hastings would exit the board in June.
- Friday was the week's defining session: Iran's foreign minister declared the Strait of Hormuz open to all commercial vessels during the ceasefire. Oil plunged more than 11% on the day, sending airlines, cruise operators and fuel-sensitive companies surging. The S&P 500 rose 1.2% to another all-time high.
- Under the surface, structural uncertainty remained: the U.S. naval blockade of Iranian ports formally stayed in place, the ceasefire was still temporary, and the IMF's severe scenario — global growth collapsing toward 2% if the conflict extended — sat in the background all week.

1) The Hormuz opening changed the character of the rally
Up to Thursday evening, the week had been moving on the same logic as the one before: peace talks were progressing, oil was drifting lower on optimism, and equities were climbing partly on the so-called TACO trade — the market's working assumption that Trump would back away from any position that visibly hurt the economy. That framework had been enough to push the S&P 500 above 7,000 for the first time and to deliver back-to-back record closes by Wednesday.
Friday was different in kind, not just degree. Iran's Foreign Minister Seyed Abbas Araghchi announced on social media that the Strait of Hormuz was open to all commercial vessels for the remaining period of the ceasefire. President Trump confirmed the announcement, though he made clear the U.S. naval blockade of Iranian ports would remain in place until both sides reached a permanent deal.
That combination — Hormuz open but the blockade formally intact — summed up exactly where the situation stood. The physical pressure on energy markets eased dramatically. The political and legal architecture of the conflict did not. The market's response was immediate and sector-specific: companies with large fuel bills were the direct beneficiaries, and the session made that visible in real time across airlines, cruise operators, housing and auto-related names. The rally was real, but it was built on a declaration by one party to a conflict that was still ongoing.
2) The IMF put a number on the damage — and it was not small
Monday's session had barely closed when the IMF released its April World Economic Outlook on Tuesday, and the headline framing was direct. The fund cut its forecast for global growth to 3.1% in 2026, down from the 3.3% it had projected in January and well below the 3.4% expansion recorded in 2025. The fund also marked up its expectation for global inflation to 4.4%, from 4.1% in 2025.
What made the revision striking was the counterfactual. Absent the war, the IMF's models would have shown a slight upward revision for 2026. The entire downward move was attributable to the Middle East conflict. The fund's chief economist Pierre-Olivier Gourinchas wrote directly that "war in the Middle East has halted this momentum," and the document made clear that the reference forecast assumed a short-lived, contained conflict. A severe scenario — in which the energy shock extended into 2027 and forced central banks to tighten — implied global growth dropping toward 2%.
That number sat in the background all week, reminding investors that the ceasefire they were trading was fragile and that the macro damage already accumulated was not going to be reversed by a social media post from the Iranian foreign minister. The stock market could price resolution. The global growth forecast could not afford to.
3) The rebound reached new highs, but the market still traded the war
Technically, the week completed something that three weeks of losses had interrupted. The S&P 500 hit its third consecutive record close by Friday, and the Nasdaq notched its longest winning streak since 1992. By any conventional measure, the market had erased the war.
But the framing was more complicated than the price level suggested. Investors were not pricing a peace deal — they were pricing the expectation of one, and doing so against a backdrop where the naval blockade was still formally operative and the ceasefire had an expiry date. The resilience was real. So was the concentration of the bet: every investor sitting at a record high was implicitly positioned for a diplomatic outcome that had not yet been formally agreed.
Friday's session illustrated that dynamic cleanly. The trigger was not a peace treaty but a unilateral Iranian announcement that left Trump's blockade in place. Stocks soared anyway, because investors needed the physical constraint on oil supply to ease — and the Hormuz opening delivered that, conditionally and temporarily. The week closed with markets at all-time highs and the war technically still ongoing, which is both a remarkable feat of forward-looking pricing and a concentrated source of risk for the week ahead.
4) The energy repricing was immediate and company-specific
The week's oil move was striking enough to demand its own section. WTI falling more than 16% in a week is not a minor adjustment — it was the worst weekly performance for crude since April 2020, the month when futures briefly went negative. The comparison gives some sense of how concentrated and violent the move was once the Hormuz constraint appeared to lift.
For the real economy, the implications were immediate and visible by sector. Airlines were the most direct beneficiary: United gained 7.1% on Friday alone, Southwest 5.1%. Cruise operators saw similar moves, with Royal Caribbean surging over 7% and Carnival close behind. The IEA had warned earlier in the week that Europe had roughly six weeks of jet fuel supplies remaining. That warning looked very different on Friday than it had on Wednesday.
The broader implication runs further than one day's price action. Every company that had adjusted guidance, pulled capacity growth or warned on fuel costs in the prior two weeks was now sitting in a different world. The question for the next few reporting cycles is how many of those guidance cuts get revised upward, and how quickly, if oil stabilises at these levels. Airlines, logistics operators and energy-intensive manufacturers will be the first places to look.
5) The IPO market reopened and corporate stories competed with macro
Even in a week dominated by geopolitics and oil, the corporate calendar made its own statement. Madison Air Solutions raised $2.23 billion in the largest U.S. IPO of 2026, with shares jumping 18.5% on their NYSE debut to give the Chicago-based HVAC and ventilation company a market value of $15.65 billion. The deal was also the biggest U.S. industrial listing since UPS raised $5.5 billion in 1999 — a comparison that carries weight precisely because 1999 was another moment when a specific infrastructure theme, in that case the internet, was drawing capital into industrials at scale. This time the theme is AI data center cooling.
Netflix added a different kind of corporate signal. The revenue beat — $12.25 billion for the first quarter, up 16% year on year — was real and unambiguous. But the 9% after-hours decline reflected two things that complicated the headline: softer second-quarter margin guidance, with operating margins expected to dip 1.5 percentage points, and the announcement that co-founder Reed Hastings would leave the board in June. Analysts broadly told clients to buy the dip, pointing to the underlying business strength, but the market's immediate reaction was a reminder that governance and forward guidance matter as much as the quarterly beat.
On the deal front, Hexagon agreed to acquire Baker Hughes' Waygate inspection technology unit for $1.45 billion, extending the industrial M&A thread that had run through the prior weeks. Strategic deal activity has not paused despite the macro disruption, which is itself a signal: companies with strong balance sheets and clear strategic rationale are still moving, even in a market defined by geopolitical uncertainty.
6) What the week tells you
The first conclusion is that this week was structurally different from the ones before it. The prior two weeks had been defined by the ceasefire and a falling oil price. This week added record-high equity markets and a formal reopening of the world's most important oil shipping lane — even if that reopening came with a U.S. naval blockade still formally intact.
The second is that the market's forward-looking bet is now fully visible and fully priced. Stocks at all-time highs, with the war technically ongoing and the blockade in place, represent a collective wager that resolution is coming. That wager may prove correct. It is also concentrated and exposed to any diplomatic setback, any reversal in oil flows or any data point that suggests the inflation damage is spreading beyond energy into core prices.
The third is that the macro damage is documented and will persist regardless of how quickly the conflict ends. The IMF's revised numbers — 3.1% global growth, 4.4% inflation — reflect damage that is already in the system. The energy shock fed into company costs, consumer prices and central bank calculations. None of that reverses overnight, and the next few earnings seasons will be the first real accounting of how deep it went.
The final point is that company-specific stories are now competing seriously with macro for investor attention. Madison Air's IPO, Netflix's quarter, Hexagon's acquisition: these were not sideshows this week. They were real signals that markets were functioning, risk appetite was returning and capital allocation was moving again across sectors. The week closed with all-time highs and a lot of unresolved questions — a combination that is exciting and uncomfortable in equal measure.
