There is an uncomfortable truth embedded in the Q1 2026 earnings season for America’s largest banks: the Iran war has been extraordinarily good for Wall Street trading desks. Not good in a way that anyone will celebrate publicly, but good in the way that prolonged volatility, elevated energy prices, geopolitical repositioning, and a surge in client activity across equities, fixed income, and commodities always translates into record revenues for the firms that sit at the centre of global capital markets.
By the time Morgan Stanley reported on April 15 — the last of the major US banks to disclose first-quarter results — the picture was complete. Goldman Sachs had posted record equities trading revenue. JPMorgan Chase had reported a 13% profit gain on record trading and investment banking fees. Bank of America delivered its strongest earnings-per-share figure in roughly twenty years. Morgan Stanley itself recorded the highest quarterly revenue in its history. Every major Wall Street bank had beaten analyst expectations. And every CEO, to varying degrees, had used their earnings call to signal that the outlook ahead is more complicated than the headline numbers suggest.
The Trading Engine
The mechanism behind the quarter’s exceptional numbers was not mysterious. When global markets are rattled — when oil prices double, when geopolitical risk reprices equity valuations overnight, when currency movements become unpredictable, when bond yields spike and then reverse on ceasefire news — institutional investors trade more, hedge more, and seek execution through the prime brokerage, derivatives, and market-making infrastructure that the largest banks provide. That infrastructure does not care whether markets go up or down. It profits from volume and from volatility.
Goldman Sachs reported net revenues of $17.23 billion for Q1 2026, up 14% year-on-year, and net earnings of $5.63 billion, up 19%. The standout number was equities trading: $5.33 billion, up 27% from the prior year and a record for the firm’s equities desk. The result was driven by prime brokerage lending to hedge funds and robust cash equities volumes — both of which are directly amplified by the kind of heightened market activity that geopolitical uncertainty generates. Goldman CEO David Solomon acknowledged the environment with characteristic precision: “The geopolitical landscape remains very complex — so disciplined risk management must remain core to how we operate.”
Morgan Stanley’s quarter was even more striking. Total revenue reached a record $20.58 billion, up 16%, with profit jumping 29% to $5.57 billion. Equities trading surged 25% to a record $5.15 billion. Fixed income revenue — boosted by commodities desks that capitalised on energy price swings — jumped 29% to $3.36 billion, enough for Morgan Stanley to surpass Goldman Sachs in that trading category during the period. Investment banking revenue surged 36% to $2.12 billion on rising fees from completed mergers and stock and bond underwriting. The firm’s CFO Sharon Yeshaya observed that market volatility had “provided an opportunity for us to showcase advice” — a polished framing for the straightforward reality that crisis creates demand for the services Wall Street sells.
JPMorgan Chase’s 13% profit gain and Bank of America’s strongest EPS in twenty years — $1.11 per share against a consensus forecast of $1.01 — completed a sweep that confirmed the pattern across the industry. Q1 2026 was structurally exceptional for Wall Street in ways directly traceable to the conflict in the Middle East.
The Investment Banking Anticipation
Beyond trading, the other thread running through the Reuters earnings preview from April 8 was investment banking. Goldman CEO David Solomon had said in March he expected mergers and acquisitions activity to accelerate in 2026 despite the war’s disruptions. Morgan Stanley CFO Sharon Yeshaya had told investors in January that the bank was seeing an accelerating pipeline in M&A and initial public offerings, particularly in healthcare and industrials. And Baird banking analyst David George had anticipated, correctly, that “trading volumes would benefit from recent geopolitical risk, while investment banking, mortgage and wealth are likely softer until the conflict is resolved.”
That bifurcation played out largely as expected. Trading was exceptional across the board. Investment banking was firm but not explosive — Morgan Stanley’s 36% surge in advisory fees was partly the release of delayed deals rather than a reflection of current confidence. The deals completing in Q1 were largely agreed before the war began; the pipeline for Q2 and beyond is a different, more uncertain question.
Jamie Dimon, in his annual letter to shareholders issued ahead of JPMorgan’s earnings, framed the macro risk as plainly as any banking CEO had in years. The US-Israeli war on Iran, he wrote, carries risks of oil and commodity price shocks that could keep inflation sticky and push interest rates higher than markets currently expect. Dimon’s warning was not an outlier view — it was the consensus of every major bank’s risk assessment, delivered in varying degrees of explicitness from every earnings call.
The Outlook Question
The question that investors came to these earnings calls to ask — and that none of the banks could fully answer — was about the forward path. Record trading revenue in Q1 is a function of volatility that may not persist. A ceasefire, a peace deal, or simply a normalisation of oil prices would reduce the elevated activity levels that made Q1 exceptional. And the structural questions about loan growth, credit quality, and the US economy are shaped by whether the Iran war’s energy shock proves transient or durable.
RBC Capital Markets analyst Gerard Cassidy highlighted commercial and industrial loan growth as a key watch item. Federal Reserve data showed C&I lending accelerated in Q1, but Cassidy cautioned that prolonged Middle East conflict and elevated oil prices could weigh on that trajectory if corporate confidence deteriorates. Commercial real estate — already under pressure before the war began, from higher rates and remote work — faces an additional headwind if the energy shock feeds into a broader economic slowdown.
The consumer picture is similarly mixed. Bank of America CEO Brian Moynihan described seeing a “resilient American economy” in the data, with solid consumer spending. But across the industry, analysts noted that lower-income households are more exposed to higher gasoline prices than the affluent customers who generate most of the wealth management and premium banking fees that drove headline results. The resilience observed in Q1 may be more accurately described as the resilience of the portion of the US economy that Wall Street banks primarily serve.
The American Advantage in the Middle of Crisis
One structural observation deserves emphasis. The contrast between US bank performance in Q1 2026 and the more complicated picture at European peers is instructive. Morgan Stanley, Goldman, JPMorgan, and Bank of America benefited from volatility generated by a conflict in which they had no geographic exposure. Their trading infrastructure is positioned in New York and London; their clients are global institutions that move money in response to geopolitical events rather than enduring the direct operational disruptions of them.
European banks with Gulf exposure — HSBC, Barclays — face a more complicated picture, with trading gains offset by asset write-downs, insurance cost increases, and the disruption of business infrastructure in an active war zone. The divergence reflects a structural reality that has been visible in previous geopolitical shocks: American financial institutions are frequently among the primary financial beneficiaries of global instability they did not create.
That reality does not make the outlook for Q2 and beyond straightforward. A ceasefire that holds and oil prices that normalise would compress the trading margins that made Q1 exceptional, and the investment banking pipeline — which the Reuters preview correctly identified as the more durable driver of long-term bank profits — would need consumer and corporate confidence to return before it can fully deliver. The record numbers of April will not simply repeat themselves in July. The Iran war made Q1 exceptional. What comes after it determines whether Q1 was a beginning or a peak.
