Investors: Stay the Course Amid the Middle East Conflict

On February 28, 2026, the U.S. and Israel launched “Operation Epic Fury” against Iran, initiating a geopolitical shock to global financial markets. As of April 20, 2026—Day 52 of the conflict—peace talks in Islamabad collapsed, the U.S. announced a naval blockade of Iranian ports, oil prices are hovering around $100 per barrel, and now peace talks are (maybe?) back on again. Throughout all of this, the Strait of Hormuz, through which approximately 20% of global oil and liquified natural gas (LNG) flows, remains largely closed to commercial traffic.

The Iran war began with coordinated U.S. and Israeli airstrikes targeting Iran's military infrastructure, nuclear facilities, missile capabilities and leadership, with Iran’s Supreme Leader Ali Khamenei killed in the opening attack. Iran responded with ballistic missiles and drones directed at Israel, U.S. military bases across the Gulf, and civilian infrastructure in Arab states hosting American forces. The Strait of Hormuz was effectively closed, triggering the largest oil supply disruption in recorded history, according to the International Energy Agency (IEA).

A fragile two-week ceasefire was declared in early April, producing a sharp but short-lived relief rally in equity markets and a plunge in oil prices. However, 21-hour peace negotiations in Islamabad collapsed on April 12, followed by a U.S. Navy blockade of Iranian ports that began on April 13. Then, on April 17, Iran declared the Strait reopened, causing oil prices to fall and U.S. stocks to return to near all-time highs. But within 24 hours, Iran re-closed the Strait and oil prices reversed once again. At the time of this writing, a fresh round of negotiations is reportedly scheduled to begin on April 21 in Islamabad.

This sequence of events is a real-time demonstration of why tactical portfolio repositioning around geopolitical signals has historically been a losing strategy. For investors, this conflict continues to pose a layered set of risks: significant energy price inflation, stagflation risk, Federal Reserve policy uncertainty, global equity volatility and credit market stress. And, as we’ve seen, geopolitical events, even severe ones, have a poor track record of justifying wholesale portfolio repositioning.

Market risks

One of the more significant systemic risks to investor portfolios to emerge from this crisis is not a near-term market decline but the re-emergence of stagflation—a combination of slowing growth and rising inflation. Energy shocks are among the few reliable historical triggers of stagflationary environments, with the 1973 OPEC embargo representing a prime example. A sustained oil price shock feeds directly into headline CPI, compresses consumer spending and raises input costs for a broad scope of industries. These types of supply-driven inflationary shocks have the potential  to limit the Federal Reserve's ability to support economic growth through interest rate cuts. Under this scenario, equities and traditional fixed income each face meaningful headwinds, making diversification across inflation-sensitive assets critically important.

As of April 20, broad equity markets have generally returned to near all-time highs, seeming to indicate that equity markets have increasingly come to believe that the impact of the Middle East conflict will be a relatively short-term blip in an otherwise positive economic and earnings environment. Despite the relatively optimistic response of equity markets, interest rates remain elevated when compared to pre-war levels. This seems to reflect the bond markets’ ongoing concerns about the timeline for restoring war-damaged energy infrastructure in the Middle East and the long-term inflationary impacts of resultant energy supply shocks.

Portfolio implications

The present conflict contains several features that distinguish it from prior geopolitical episodes. The scale of energy market disruption, characterized by the IEA as the largest supply shock in history, is not typical. The simultaneous presence of tariff policy uncertainty, elevated government deficits and a fragile ceasefire creates a complex macroeconomic environment. The risk of a prolonged conflict, as evidenced by the collapse of the Islamabad talks, is not trivial. Rather than wholesale repositioning of portfolios in response to geopolitical headlines, we believe that long-term investors often seek to rely primarily on their established strategic asset allocation plan.

Key strategic considerations to help weather geopolitical shocks

Rather than reactive portfolio management, we believe an effective response to geopolitical risk is forward-looking and strategic portfolio architecture. Strategic investment plans designed with explicit recognition of geopolitical risk as a permanent feature of the macro landscape are inherently more resilient than those built solely around peacetime return assumptions.

Geographic and sector diversification

The Iran war has had a range of impacts across various regions and countries. Asian economies, highly dependent on Middle Eastern LNG, are more severely impacted than the U.S., which is buffered by domestic production. U.S.-based Permian Basin producers have benefited from the energy shock, while European majors that pivoted toward renewables appear less positioned to capitalize. A globally diversified portfolio that includes exposure to domestic energy production, defense and aerospace, and infrastructure is inherently more resilient to regional geopolitical disruptions than one that is concentrated in technology and large-cap domestic growth equities.

Dynamic rebalancing as a tactical tool

Rather than making large tactical bets on market outcomes, strategic plans should consider pre-defined rebalancing triggers. If equity markets decline materially, disciplined rebalancing back to target weights effectively buys equities at lower prices. This is a systematic form of tactical adjustment that does not require the investor to predict market direction. Similarly, if energy or commodity exposures appreciate beyond strategic targets, trimming back to target is a systematic way to realize gains without making a directional call on oil prices.

Liquidity management and alternative investments

Investors with exposure to private equity, private credit and other illiquid alternatives should evaluate whether their liquidity management framework is designed to withstand prolonged periods of public market volatility without forcing asset sales. Portfolios with adequate liquidity buffers, typically 12–24 months of planned distributions held in high-quality liquid assets, can more easily hold their illiquid positions through market disruptions and benefit from their long-term return premiums without being forced to sell at depressed prices. Maintaining adequate liquidity also gives investors the option to take advantage of opportunities that may present themselves, such as adding assets that may do well in a stagflationary environment that have yet to appreciate in price.

5 principles to guide investors

The U.S./Iran war is a severe geopolitical shock with real implications for energy markets, global growth and inflation. It is not, however, a reason to abandon long-term investment discipline. The historical record is unambiguous: investors who make large tactical bets on geopolitical outcomes run a significant risk of underperforming those who maintain diversified strategic allocations, depending on timing, implementation and market conditions.

We believe the following five principles should guide investor decision-making in the current environment:

1. Maintain strategic asset allocation targets. Be cautious about making large defensive shifts. Markets have already priced in significant geopolitical risk, and recoveries can be swift and severe.
2. Investors should carefully evaluate geopolitical hedges after they have appreciated. Gold, energy equities and defense stocks have already rallied substantially. Adding them now accepts crisis pricing with less attractive upside from current levels.
3. Use rebalancing discipline rather than tactical bets. If equity declines have caused portfolios to drift below target weights, we believe systematic rebalancing is often an appropriate response rather than selling risk assets to assume a more defensive posture.
4. Stress-test portfolios and financial independence projections against a period of prolonged inflation and modest growth. If the portfolio cannot withstand 12+ months of elevated oil prices and restricted Federal Reserve rate-cutting capacity, the strategic plan requires adjustment—not tactical trading.
5. Behavioral risk in the form of panic selling in reaction to frightening headlines can pose as a threat to long-term wealth outcomes in this highly uncertain environment.

The time to prepare for geopolitical shocks is before they occur, not while they are unfolding. Investors who arrive at a crisis with well-diversified, stress-tested, liquidity-aware portfolios need only to maintain discipline. Those who are unprepared face a difficult choice between two bad options: they can act on imperfect information in real time, or hope their plan that was designed for ideal conditions proves resilient in a time of crisis.

The Path to Normalization

The path to a peace agreement remains shrouded in the fog of war and exactly what each side would view as acceptable terms for a lasting agreement. In the case of the U.S., the goals seem to be an open Strait of Hormuz free from Iranian influence, the end of (or at least meaningful delay in) Iranian nuclear enrichment, and avoiding the negative consequences of a protracted war. It may be assumed that the Iranians view this conflict as an existential threat to their existence. They are basically isolated from the rest of the world and have seen their political and military leadership, and much of their military capacity, wiped out by Israeli and U.S. air power. Thus, maximalist U.S. demands will likely be viewed as non-starters by the Iranians—they have been backed into a corner and will probably play whatever cards they have left to survive. The negotiations will undoubtedly be fraught and predicting how they will play out seems to be a fool’s errand.

Even if the conflict in the Middle East continues for an extended time, the opening of the Strait of Hormuz, and the ability of ships to safely transport oil and other products to an energy-hungry world, remains key to market and economic normalization. There are numerous examples of markets being largely unaffected by war in the Middle East. One example is the Iran/Iraq War, which began in 1980 and did not end until 1988. The war claimed over one million lives, with little to no impact on energy prices and the global economy. If the Strait of Hormuz opens and the oil flows again, energy market pressures may ease, supporting broader economic conditions and market recovery.

As we have outlined above, the risk of a “black swan” event remains a very real possibility. Yet, after an initial sell-off, followed by intermittent bouts of volatility (both up and down) around certain news events, markets have remained relatively calm. The investors who are best positioned to weather this storm are those who maintain discipline and follow their strategic plans.
