UBS Portfolio Playbook for Uncertain Markets

UBS’s latest Global Risk Radar urges investors to construct portfolios that can adapt to a range of possible market outcomes rather than relying on a single forecast, citing ongoing uncertainty around geopolitics, inflation, interest‑rate expectations and the rapid evolution of artificial intelligence as drivers of volatility for the coming year.

Base‑Case Outlook

  • The bank expects the S&P 500 index to reach 8,200 by June 2027, underpinned by resilient U.S. economic growth, continued AI‑related spending, solid corporate earnings and government investment.
  • Shipping through the Strait of Hormuz is projected to recover gradually over the next two to three months, while easing bond yields are expected to improve the outlook for fixed‑income assets.
  • UBS recommends deploying excess cash, locking in current bond yields, and maintaining broad diversification across regions and asset classes. Rather than concentrating on recent winners, the bank suggests rotating capital into higher‑conviction opportunities as market leadership evolves.

Downside Scenario (20% Probability)

  • Disruptions to oil shipments through the Strait of Hormuz could persist for an additional three to six months, and enthusiasm for AI investment may fade.
  • In this environment, Brent crude could climb to $150‑$200 per barrel, and global equity markets could experience double‑digit declines.
  • UBS advises preserving capital by increasing exposure to high‑quality government bonds, investment‑grade credit, selected alternative investments, and commodities that can hedge intensified inflationary pressures.

Bullish Scenario (20% Probability)

  • Shipping through the Strait of Hormuz is expected to normalize by late July, with oil prices remaining below $80 per barrel.
  • Stronger‑than‑expected earnings growth from AI‑related investment would provide fresh support for equities.
  • The bank sees scope to raise exposure to growth‑oriented sectors, but cautions against chasing market momentum, recommending periodic rebalancing and continued diversification as conditions evolve.

Central Message

Across all three scenarios, UBS stresses that portfolios designed to adapt to changing market conditions are likely to be more resilient than those built around a single market forecast.
