Financial markets staged a dramatic comeback earlier this week, but some strategists on Wall Street warn investors may be celebrating too soon.

A violent swing in oil prices triggered one of the most dramatic intraday reversals in recent months. At one point, Dow futures were down more than 1,000 points as traders reacted to escalating tensions between Iran, Israel, and the United States. By the end of the trading session, however, the market had rebounded sharply, with the Dow finishing roughly 200 points higher.

The sudden reversal rewarded aggressive buy the dip traders who stepped in during the panic. But analysts at Bank of America caution that the geopolitical situation remains volatile and could still deliver major shocks to financial markets.

Bank of America Warns of Iran’s “Scorched Earth” Risk

Strategists at Bank of America, led by Nitin Saksena, believe the biggest risk investors face is assuming the worst of the conflict is already behind them.

“With the Iranian regime doubling down on hardline leadership (and having burnt bridges with neighbors), the risk lies in assuming we are out of the woods. A scorched earth strategy aimed at maximizing economic disruption to shock financial markets remains perhaps their most potent lever,” the strategists said.

In geopolitical terms, a scorched earth strategy typically involves actions designed to cause maximum disruption to infrastructure, trade routes, and energy supplies. In Iran’s case, that could mean targeting shipping lanes, energy facilities, or critical regional infrastructure in the Middle East.

For global markets, the most immediate threat would be disruptions to oil supply.

Why the Strait of Hormuz Matters So Much

One of the most important pressure points in the current conflict is the Strait of Hormuz, the narrow waterway connecting the Persian Gulf to global shipping lanes.

Roughly 20 percent of the world’s oil supply moves through this corridor each day.

Even the perception of risk to the strait can cause massive swings in energy markets. Over the past week, oil prices have moved sharply higher and then pulled back as traders try to assess whether Iran could attempt to disrupt shipping in the region.

If the strait were blocked or severely disrupted, energy prices could spike rapidly. Some analysts believe oil could surge well above $150 per barrel under a worst case scenario.

That type of shock would ripple across the entire global economy.

Higher oil prices feed directly into inflation, transportation costs, and consumer spending. They also affect central bank policy decisions, particularly for the Federal Reserve.

Market Volatility Driven by Momentum Trades

Bank of America strategists also pointed out that the market selloff during the escalation was concentrated in sectors that had previously been performing extremely well.

These included:

• U.S. materials stocks
• Emerging market equities
• Metals and mining companies

These sectors had experienced strong momentum in recent months, making them particularly vulnerable to sharp reversals when geopolitical uncertainty spiked.

“In our view, these observations highlight how periods of high uncertainty can amplify momentum and reflexivity in markets, pushing prices away from fundamentals and leaving the most crowded trades vulnerable to sharp positioning and sentiment driven reversals,” the strategists said.

This dynamic is becoming increasingly common in modern markets, where algorithmic trading and passive investment flows can amplify moves in both directions.

Understanding Bank of America’s Bubble Risk Indicator

One of the tools Bank of America uses to identify crowded trades is its Bubble Risk Indicator, often referred to as BRI.

The indicator measures an asset’s:

• Price momentum
• Volatility
• Return patterns
• Market fragility

These factors are combined into a score ranging from zero to one.

A reading close to one suggests the asset may be experiencing bubble like behavior driven by speculation or crowded positioning.

When markets experience sudden shocks such as geopolitical conflict, assets with high BRI readings often experience the fastest and most violent reversals.

That appears to have happened during the latest market turmoil tied to the Iran conflict.

Oil Markets Swing as War Uncertainty Continues

While markets rebounded after the initial panic, energy prices remain extremely sensitive to new developments.

U.S. stock futures rose modestly on Tuesday as oil prices fell sharply after a brief surge earlier in the week.

However, the geopolitical situation remains fluid.

Iran launched additional attacks on Israeli and Gulf targets shortly after the market rebound, raising fears that the conflict could escalate further.

At the same time, mixed signals from President Donald Trump about the potential duration of the conflict have added to investor uncertainty.

Markets generally prefer clarity during geopolitical crises. When investors do not know whether a conflict will last days, weeks, or months, volatility often increases dramatically.

Why Investors Should Pay Attention

Geopolitical shocks historically create some of the largest short term market moves.

Past conflicts in the Middle East have frequently triggered:

• Oil price spikes
• Airline and travel sector declines
• Defense stock rallies
• Increased demand for gold and safe haven assets

Investors have already begun positioning for some of these outcomes.

Defense companies have seen increased interest from traders expecting higher military spending. Meanwhile, gold prices have climbed as investors look for protection against potential inflation shocks tied to energy markets.

Energy companies could also benefit if oil prices remain elevated for a prolonged period.

The Inflation Wild Card

One of the biggest concerns for policymakers is how rising oil prices could affect inflation.

Energy costs play a major role in the price of goods and services across the economy. If crude prices surge sharply, it could complicate the Federal Reserve’s efforts to manage inflation and interest rates.

Higher energy costs also act as an indirect tax on consumers.

When Americans spend more at the gas pump, they often spend less on discretionary goods and services. That dynamic can slow economic growth and impact corporate earnings.

A Market Environment Prone to Sudden Swings

The sharp reversal in Dow futures this week highlights how fragile market sentiment can be during periods of geopolitical tension.

Investors who rushed to sell during the early panic were quickly forced to reassess their positions as markets recovered.

But Bank of America strategists caution that the broader risk has not disappeared.

If Iran chooses to escalate the conflict in ways that disrupt global energy markets or trade routes, financial markets could face another wave of volatility.

For investors, the key takeaway may be that the current rally could prove fragile if geopolitical tensions intensify again.

What Smart Investors Are Watching Now

Several indicators could signal whether the conflict is beginning to seriously affect global markets.

These include:

• Oil prices approaching $120 to $150 per barrel
• Rising shipping insurance costs in the Persian Gulf
• Increased military activity near the Strait of Hormuz
• Sharp moves in the VIX volatility index

If these indicators begin to move aggressively higher, it could suggest the conflict is entering a more dangerous phase for global markets.

Until then, investors are likely to remain caught between optimism that tensions will ease and fears that the situation could escalate quickly.
