Market and investment implications of escalating tensions in the Middle East

Opinions and commentary by the Multi-Asset Solutions Team, SLGI Asset Management Inc.

Military conflict between Iran, the U.S. and Israel has intensified tensions in the Middle East and increased security concerns across neighbouring Gulf countries and key economic corridors.

Given the region’s importance to energy supply and trade flows, these developments have contributed to renewed volatility, particularly across oil markets and inflation-sensitive assets. The following analysis examines the potential implications for markets and portfolios as the situation evolves.

Why is this important?

This conflict has the potential for significant global impact as it increases the risk of economic and financial stress across many regions and sectors.

These military developments may contribute to prolonged uncertainty within the region, even if near-term miliary activity subsides. Iran is already constrained by global sanctions and is economically fragile.

In response to the conflict, Iranian officials have publicly signalled that they are willing to disrupt energy flows, including by threatening or closing maritime chokepoints, especially the Strait of Hormuz, a narrow water passage connecting the Persian Gulf to the Arabian Sea, where 20 million barrels of oil and 20% of the global volume of liquefied natural gas (LNG) transits daily. These constraints on shipping through the Strait are already pushing energy prices higher, increasing the risk of inflation and possibility of slower economic growth.

Immediate investment implications

The initial market reaction has been textbook risk-off reflecting the regional disruption: oil prices up and a broad sell-off across riskier assets. Sectors and regions exposed negatively to higher oil prices (especially transports, cyclicals, Europe, Asia) are already showing signs of underperformance.

Going forward, two possible scenarios are (a) a contained conflict resulting in an elevated but mean-reverting geopolitical premium in oil; or (b) a protracted conflict where the disruption of the Strait of Hormuz leads to an environment of stagflation. A third lower-probability scenario would be where broader regional energy infrastructure is materially impaired, which impacts oil supply even after the end of the conflict.

Potential cross-asset implications: interest rates, winners/losers, geopolitics

Interest rates

Risk of sustained energy inflation is complicating the near-term outlook for bonds because central banks become more cautious about interest rate cuts in “oil shock” scenarios. This means bond yields become a tug-of-war between growth fear (bullish duration) and inflation persistence (bearish duration).

Equities

There will likely be significant equity dispersion by industry and geography. Sectors that could potentially benefit include energy (upstream; select integrated), defence/aerospace, some shipping/logistics beneficiaries if freight rates surge, and commodity-linked markets less exposed to import energy costs. Sectors that will likely suffer include airlines and transport, energy-intensive industrials, emerging market importers with fragile currencies and, if inflation expectations re-accelerate, rate-sensitive growth sectors.

Currency and commodities

The U.S. dollar and gold have historically benefited in times of conflict, with gold’s role particularly emphasized as a geopolitical hedge in diversified portfolios. Gas and LNG also deserve attention because a meaningful share of LNG flows via the Strait of Hormuz, making this a story about all industries related to producing, managing and distributing energy products, not just crude oil.

Geopolitics

The investment macro regime remains one of fragmentation and supply-side shocks. The long-term market impact from current events in Iran hinges on the duration of the conflict, the impairment of shipping energy through the Strait of Hormuz, and the political end-state.

What should investors do?

• Maintain diversification and rebalance systematically. Avoid indiscriminate de-risking and instead consider diversifying and potentially rebalancing back to strategic plan.
• Reassess inflation hedges. If energy risks persist, re-asses if portfolios have adequate real-asset exposure (select commodities, quality energy, infrastructure where appropriate) and consider the role of gold as geopolitical insurance.
• Be selective in credit and emerging markets. Wider spreads can create opportunity but focus on balance-sheet resilience and avoid issuers with concentrated Gulf sensitivity until visibility improves.
• Prepare for two-way rate risk. Maintain caution on duration positioning and recognize that “flight-to-quality” bond rallies may be less reliable if the shock becomes inflationary.

In short, the conflict in Iran may have materially raised geopolitical risk and market volatility, but it has not yet altered the fundamental need for balanced portfolios, a long-term focus, and measured decision making in the face of uncertainty.
