Why Morgan Stanley Still Likes U.S. Stocks Over the Next 6 to 12 Months: Geopolitical Conflict Unlikely to Alter the Medium-Term Trend

In global financial markets, geopolitical conflicts often amplify investor emotion very quickly, especially when the conflict involves the Middle East, energy supply, and international shipping security. In those cases, worries about oil prices, inflation, and economic growth tend to rise at the same time. Recently, tensions between the U.S. and Iran have flared again, sparking broad discussion about a possible spike in energy prices and pressure on risk assets. Still, Morgan Stanley’s view is fairly clear: unless the conflict drives oil prices to surge in a historic way and stay elevated for a while, the event is unlikely to change its bullish outlook for U.S. stocks over the next 6 to 12 months.
That view reflects not only how institutions distinguish between short-term shocks and medium-term trends, but also the core logic behind current U.S. market pricing: what drives the stock market is often not a single event, but whether that event is strong enough to change the three key variables of earnings, rates, and liquidity.
1. Geopolitical conflict can rattle markets, but not necessarily change the trend
History shows that geopolitical conflicts usually push up volatility in the short term. Money quickly moves into gold, Treasuries, and the dollar as safe havens, while stocks, oil-sensitive industries, and emerging-market assets may come under near-term pressure. But whether such a shock becomes a lasting trend reversal depends on whether it changes the underlying logic of the macro economy.
The core of Morgan Stanley’s judgment here is “oil prices.” For U.S. stocks, a short-lived jump in oil can usually be absorbed through a higher risk premium. But if oil prices surge in a historic way and stay high for a long time, a chain reaction may follow: higher energy costs, renewed inflation expectations, delayed policy easing, compressed profit margins, and ultimately real pressure on equity valuations.
In other words, the conflict itself does not necessarily set the market direction; what matters is whether it changes the economic and policy backdrop through the oil-price channel.
2. Oil prices are the key variable for U.S. stocks
Why are oil prices the most important indicator in Morgan Stanley’s view? Because oil is not just an energy-price signal; it is a combined variable for inflation, consumption, and corporate costs.
First, higher oil prices directly raise transportation and living costs for U.S. households, reducing disposable income. In a consumption-driven economy, when consumer confidence weakens, revenue growth at companies also comes under pressure. Second, rising oil prices increase cost pressure on transport, manufacturing, chemicals, airlines, and logistics, squeezing profit margins. Third, higher energy prices tend to revive inflation expectations, making the Federal Reserve more cautious on rates and pushing back hopes for cuts.
For U.S. stocks, the relationship between valuations and rates is especially sensitive. If an energy shock pushes inflation higher and keeps real yields elevated, growth stocks and high-valuation sectors usually face more pressure. That is why only a large and persistent oil-price spike that affects inflation and policy can truly rewrite the medium-term trend in U.S. equities.
3. The current market looks more like an event-driven disturbance than a fundamental reversal
From an asset-pricing perspective, the market is more likely to treat the U.S.-Iran conflict as an event risk rather than a systemic risk. The reason is that the U.S. economy still shows some resilience, corporate earnings have not immediately deteriorated because of geopolitical tensions, and structural growth themes such as artificial intelligence, cloud computing, and semiconductors remain intact. As long as the macro backdrop does not change fundamentally, capital will still flow toward sectors with clearer earnings certainty.
At the same time, the main support for U.S. stocks still comes from liquidity expectations, corporate earnings, and the fundamentals of leading tech companies. Over the past period, investors have largely priced in a soft landing for the U.S. economy. Even if geopolitical risks cause short-term disruption, as long as the situation does not turn into an energy crisis or a second wave of inflation, the market usually has strong repair capacity.
This also means the market may become volatile once the news hits, but unless the conflict escalates further and spreads into broader macro variables, institutional investors are still more likely to view pullbacks as opportunities to build positions rather than signals to turn bearish on the trend.
4. Market reactions under different scenarios: the key is shock severity
From an investment-analysis standpoint, future scenarios can be roughly divided into three types.
The first is a low-intensity scenario. If the conflict stays at the level of local confrontation and oil prices move only slightly before quickly falling back, risk appetite should recover fast and U.S. stocks will likely continue to follow their original fundamental trend.
The second is a moderate-shock scenario. If crude prices spike for a while but no lasting supply disruption occurs, markets may come under short-term pressure. Energy stocks would benefit relative to others, while airlines, transport, and consumer sectors would be weaker; still, the broader market may not enter a systemic downtrend.
The third is a high-intensity scenario. Only if the conflict escalates and damages the energy supply chain, pushing oil to historic highs that stay there and forcing a repricing of inflation and rate expectations, would the medium-term bull case for U.S. stocks truly be challenged. Morgan Stanley clearly believes the odds of that scenario remain limited.
So investors should not just stare at headlines. They should focus on oil prices, inflation expectations, Federal Reserve comments, credit spreads, and corporate guidance. These are the real anchors of market direction.
5. How should investors respond?
Faced with geopolitical uncertainty, a steadier strategy is not to be driven by short-term emotion, but to keep asset allocation anchored in fundamentals.
On one hand, it makes sense to add some defensiveness to the portfolio by focusing on energy, utilities, and healthcare, which can help balance volatility. On the other hand, leading tech companies and quality growth stocks with clear long-term logic and strong earnings quality should not be cut too aggressively just because of a short-term event. Especially over a medium-term horizon, if the U.S. economy remains resilient and policy becomes more flexible, high-quality assets still have room to recover and rise.
Investors should also watch out for “event-driven overreaction.” History repeatedly shows that market panic triggered by geopolitical conflicts often returns to rationality once the information becomes clearer. The real key to returns is not predicting every news shock correctly, but staying disciplined and keeping a clear view of the trend through volatility.
Conclusion
Overall, Morgan Stanley’s view on U.S. stocks sends an important signal: geopolitical risk can create volatility, but it does not necessarily change the trend. Unless the U.S.-Iran conflict drives a historic and sustained surge in oil prices, which in turn forces a systemic repricing of inflation, rates, and earnings expectations, the latest event is more likely to be a short-term disturbance than the end of the medium-term bull case.
For investors, that means paying more attention to the actual transmission from the conflict to energy prices and macro variables, rather than being led by the surface-level news flow. Over the next 6 to 12 months, the key drivers of U.S. stocks will still come back to economic resilience, corporate earnings, and liquidity conditions. As long as those fundamentals remain intact, short-term geopolitical risk is unlikely to fully reverse the medium-term bullish setup in U.S. equities.
