Morgan Stanley chose the final trading day of the first quarter of 2026 to issue one of its most significant asset allocation shifts in years, downgrading global equities to “equal weight” and simultaneously raising US Treasuries and cash to “overweight” — a move that carries significant implications for institutional portfolio positioning heading into Q2.
“Uncertainty around the magnitude and duration of oil supply disruptions is making the outlook for risk assets increasingly asymmetric,” the firm said in a research note released Monday morning.
This is not the language of tactical caution. It is the language of a major institution telling clients that the upside case for equities is now materially constrained while the downside case has grown substantially.
The context behind the call is worth spelling out. Brent crude has risen more than 55% in March alone. The Federal Reserve is constrained — it cannot cut rates into an oil-driven inflation surge and cannot hike into a labour market that is showing signs of softening. Goldman Sachs has raised its 12-month recession probability to 30%, Wilmington Trust to 45%.
Morgan Stanley’s chief investment officer Mike Wilson had previously argued that corporate earnings resilience — S&P 500 profits expected to grow 20% in the next 12 months — provides a floor under equities even in a difficult macro environment.
That view has clearly been moderated by the latest escalation, particularly Trump’s threat on Monday morning to destroy Iranian oil infrastructure if the Strait of Hormuz is not immediately reopened.
The firm’s simultaneous shift toward cash and US Treasuries reflects the “safe haven” trade that has been building since the war began on February 28, with gold already at $4,563 and short-dated Treasury yields climbing.
Federal Reserve Chair Jerome Powell’s term expires in mid-May, and Trump has nominated former Governor Kevin Warsh as his successor — adding institutional uncertainty on top of geopolitical uncertainty at one of the most consequential moments for monetary policy in years.
For investors trying to navigate this environment, Morgan Stanley’s call is the clearest professional signal yet that the calculus around holding equities through this conflict has materially changed.
