After the oil supply shock, global equities and volatility may see pronounced regional and sector divergence

Overview

The report analyzes the impact of an oil supply shock on global equity markets and volatility. UBS believes that current Middle East-related energy transport disruptions and blockages in the Strait of Hormuz have sharply tightened the global energy balance, driven inventories down rapidly, and left limited spare capacity. Even if the shock does not worsen further, the oil price increase already seen, tighter financial conditions, and confidence shock may continue to drag on growth and corporate earnings through the year, with Europe the most exposed.

Core views

The core judgment is that the market underestimates the persistence and second-order effects of the oil supply shock. If the oil price shock is driven by constrained supply rather than stronger demand, it is more negative for risk assets and will amplify regional and sector divergence. US technology stocks are relatively favored due to low energy intensity and earnings resilience; European equities, European banks, and airlines are more vulnerable because of energy costs, confidence, credit cycle pressures, and fuel cost burdens; gold miners are supported by inflation risk, uncertainty, and lower real rates.

Analysis framework

The report uses scenario analysis and a structural oil shock decomposition framework. In the base case, global oil supply-demand balance returns to January levels only by year-end, with real oil prices rising about 30% to 40% and staying elevated for about 6 months; the bullish case assumes supply recovers to trend within 3 months; the bearish case assumes output recovers to only half of pre-war levels after one year, with real oil prices remaining about 40% higher for more than 6 months. The model calibrates the impact of oil shocks on equities, sectors, volatility, and cross-asset performance using decades of historical experience.

Methodology notes

• Macro scenario analysisBase / Bull / Bear oil supply shock scenarios

  Characterize the oil shock through output, oil price, and leading-indicator paths rather than simply setting an oil price level.

  The base, bullish, and bearish scenarios correspond to different supply recovery speeds, different magnitudes and durations of the real oil price shock, and are used to derive nonlinear effects on global growth, inflation, and asset returns.

• Structural commodity modelOil shock decomposition framework

  Decompose oil price changes into current supply shocks, current demand shocks, future supply risk shocks, and future demand expectation shocks.

  The same oil price increase can stem from supply disruptions, stronger demand, inventory hoarding, or future growth expectations, each with completely different market implications; this framework seeks to identify the economic drivers behind the rise in oil prices.

• Cross-asset mappingStructural shocks to asset returns and volatility mapping

  Map structural oil shocks to the performance of assets such as equities, volatility, rates, credit, and FX relative to their own baseline paths.

  Rather than providing unconditional market forecasts, the report estimates excess returns and volatility changes for each asset relative to baseline under different sources of oil price shocks.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Nasdaq 100 (NDX)

  A relative beneficiary; recommended to express relative outperformance by buying NDX calls or selling NDX puts.

  Strengths

  High share of technology- and intellectual property-driven companies, low direct energy intensity, and strong pricing power and balance-sheet resilience.

  Weaknesses

  Still affected by long-duration growth stock valuations, interest rates, and overall risk appetite.

  Comparison

  Compared with the STOXX 50 and European banks, NDX has lower direct exposure to imported energy shocks and a European growth slowdown.

  Risks

  If oil prices fall and European growth recovers quickly, NDX's relative outperformance may narrow.

• STOXX 50 (SX5E)

  A relative laggard; the report recommends selling SX5E calls to fund NDX calls.

  Strengths

  If the shock fades quickly, European valuations and cyclical exposure could offer rebound potential.

  Weaknesses

  Europe is highly dependent on imported oil and gas, and higher energy prices directly compress household real income, corporate margins, and confidence.

  Comparison

  Compared with NDX, SX5E is more vulnerable to energy supply shocks, inflation constraints, and limited policy space.

  Risks

  If energy supply recovers quickly and geopolitical risks fade, selling upside options may incur losses.

• European equity volatility / SX5E volatility

  Recommended to go long European equity volatility relative to US volatility.

  Strengths

  European macro risk, earnings uncertainty, and policy constraints may drive volatility repricing.

  Weaknesses

  If markets continue to stay calm or the shock eases, option time value may decay.

  Comparison

  The report argues that European volatility currently trades at only a modest premium to US volatility, below extreme levels seen during the energy crisis.

  Risks

  Volatility trades are highly sensitive to entry timing, term structure, and implied volatility pricing.

• EU Banks (SX7E)

  A relatively bearish asset; recommended to buy SX7E puts financed by selling NDX puts.

  Strengths

  If rates and the earnings environment improve, banks could still benefit from a cyclical rebound.

  Weaknesses

  European banks are highly linked to the credit cycle, confidence, loan growth, and asset quality, making them sensitive to economic slowdown.

  Comparison

  Compared with NDX, SX7E has stronger downside convexity in adverse energy and trade scenarios.

  Risks

  If European macro data improve and credit risk does not materialize, the SX7E put strategy may lose money.

• US Gold Miners / GDX

  A relative beneficiary; the report suggests considering selling JETS calls to fund GDX calls.

  Strengths

  Uncertainty, demand for inflation hedges, and lower real rates may support gold prices and gold miner margins.

  Weaknesses

  Affected by gold prices, costs, mining operations, and changes in risk appetite.

  Comparison

  Compared with airlines, gold miners are typically supported by safe-haven and inflation-hedging demand after an energy shock.

  Risks

  If real rates rise or gold prices fall, upside for gold miners may be limited.

• US Airlines / JETS

  A relatively pressured asset; the report recommends selling airline sector upside options to fund gold miner upside options.

  Strengths

  If oil prices fall quickly and travel demand remains strong, airline stocks may recover.

  Weaknesses

  Rising fuel costs, weaker demand, high fixed costs, and limited pricing power amplify earnings pressure.

  Comparison

  Compared with gold miners, airlines are a more typical cost-impaired sector under an energy shock.

  Risks

  If geopolitical conflict eases and oil prices decline, the airline sector may rebound.

Key data

• Brent crude oil priceAbove USD 100 per barrel, once approaching USD 120 per barrelReflects the scale of supply disruption and the Middle East geopolitical risk premium.
• Base-case real oil price shockUp about 30% to 40%, then retraces about half of the increase after around 6 monthsCorresponds to global oil supply not returning to January levels until year-end.
• Bullish-case real oil price shockPeak below 30%, and only slightly above pre-war levels after about 9 monthsAssumes oil supply returns to trend within 3 months.
• Bearish-case real oil price shockUp about 40%, lasting more than 6 monthsAssumes oil output recovers to only half of pre-war levels after one year.
• Historical post-energy-shock NDX performanceTypically rises 20% to 50% after one yearUsed in the report to support the long NDX versus European equities trade idea.
• Historical post-energy-shock European equity performanceTypically declines 10% to 25%Reflects Europe's high sensitivity to imported energy and macro shocks.
• Historical post-energy-shock gold miner performanceTypically rises at least 15%, and up to about 40% in some casesSupported by uncertainty, inflation risk, and falling real rates.
• Historical post-energy-shock airline sector performanceDeclines can exceed 50%Rising fuel costs, weaker demand, and high fixed costs amplify downside risk.

Impact & implications

The investment implications focus on relative value rather than outright direction. The report recommends expressing regional, sector, and volatility divergence through options structures: long US technology versus European large caps, long European volatility versus US volatility, short European banks versus US technology downside risk, and long gold miners versus airlines. If the oil shock persists, downgrades to European growth and earnings, rising risk premia, and sector margin divergence may continue to play out.

Risks

• The oil shock may fade faster than in the base case, weakening the logic of the recommended relative-value trades.
• The model relies on historical relationships, but energy structure, policy responses, market valuations, and investor positioning may already have changed.
• Options and volatility strategies face risks from time decay, liquidity, strike selection, and transaction costs.
• If European policy support exceeds expectations or corporate earnings prove resilient, downside in European equities and banks may be less severe than the model implies.
• If global demand deteriorates rapidly, NDX may also be dragged down by weaker risk appetite and earnings downgrades.
• Geopolitics, shipping security, strategic reserve releases, and changes in alternative transport routes could all alter the oil price path.

What to watch

• Whether the Strait of Hormuz and Middle East energy transportation return to normal commercial passage.
• Whether Brent crude remains above USD 100 per barrel and how long the real oil price shock lasts.
• The pace of global crude inventory drawdowns and changes in spare capacity across major producing regions.
• Whether European economic surprise indices, corporate earnings downgrades, and credit conditions continue to deteriorate.
• Whether the volatility premium of SX5E versus US equities reprices toward historical energy-crisis levels.
• Whether relative performance of NDX versus SX5E and SX7E, and gold miners versus airlines, begins to materialize.
• Whether negotiations, ceasefires, insurance costs, and shipping security assurances are sufficient to quickly normalize energy flows.
