There is a particular kind of silence that falls over trading floors and family offices alike when the news turns genuinely bad. The kind that preceded the Lehman collapse in 2008. The kind that gripped the world on March 12, 2020, when markets posted their worst single-day fall since 1987. The kind that returned on the morning of March 1, 2026, when news broke that US and Israeli forces had struck Iranian military infrastructure overnight, and Brent crude opened 13 per cent higher.
In those moments, every screen turns red, every model fails, and — most dangerously — every instinct screams sell. It is precisely in those moments that the investor’s greatest enemy is not the market. It is themselves.
This is not a new problem. Behavioural finance has documented it exhaustively. Yet crisis after crisis, the pattern repeats with near-perfect fidelity: fundamentals are abandoned, momentum reverses violently, and fear becomes the dominant pricing mechanism — only to be followed, almost without exception, by a return to reason and, with it, to value.
At Habib Bank AG Zurich, we have accompanied clients through each of these episodes — the dot-com collapse, the Global Financial Crisis, the COVID crash, and now the 2026 Iran conflict. What we have observed, consistently, is that the clients who weathered these periods with the least damage were not those with the best market-timing instincts. They were those with the clearest investment framework and the discipline — supported by their advisors — to hold to it when the world around them was doing otherwise.

The architecture of panic
To understand why investors behave so irrationally during crises, it helps to understand how the brain is wired. Humans are loss-averse by a ratio of roughly 2:1 — the psychological pain of a loss is felt twice as intensely as the pleasure of an equivalent gain. Nobel laureate Daniel Kahneman called this prospect theory, and it was formulated in the 1970s. Decades later, it plays out in every crisis drawdown with the precision of a recurring theme.
During normal market conditions, rational actors assess earnings trajectories, discount rates, geopolitical risk premia, and cash flow multiples. These are the fundamentals — the gravitational force of markets. But when an exogenous shock strikes — a pandemic, a war, a banking collapse — the cognitive architecture shifts. The prefrontal cortex, seat of rational planning, effectively cedes control to the amygdala, the brain’s fear centre. The result is momentum-driven selling that has nothing to do with underlying business value and everything to do with the hardwired human terror of being the last one out.
In asset markets, this manifests as a peculiar decoupling: the price of a stock falls not because its earnings have changed, but because its shareholders have become afraid. The asset has not deteriorated — the perception of it has. And crucially, the US Dollar Index (DXY) — a proxy for global risk appetite — tells us the precise moment when this fear has peaked.
HBZ ADVISORY PERSPECTIVE
The private banking relationship exists precisely for moments like these. A trusted advisor’s primary role during a crisis is not to predict markets — it is to prevent clients from becoming their own worst enemy. At HBZ, our advisory conversations in times of volatility are anchored in three questions: Has your investment objective changed? Has the fundamental quality of your portfolio changed? Has your time horizon changed? If the answer to all three is no, then the only thing that has changed is the headline. And headlines are not a portfolio strategy.
The historical record: What actually happened
History is the most powerful antidote to panic, and the data from major crisis periods is unambiguous. In every significant drawdown over the past three decades, markets have not only recovered — they have surpassed prior highs by substantial margins. The table below includes the most recent episode — the 2026 Iran conflict — alongside prior crises.
The pattern is consistent across each event: the S&P 500 suffers a sharp, sentiment-driven decline that overshoots fundamental value, the DXY rallies as capital seeks the safety of the world’s reserve currency, and then — once the peak of uncertainty passes — equities recover, the dollar softens, and patient capital is rewarded.
The 2026 Iran War: A live case study in crisis investing
On February 28, 2026, the United States and Israel launched coordinated strikes on Iranian military infrastructure in what the US designated Operation Epic Fury. The Strait of Hormuz — through which approximately 20 per cent of the world’s oil supply transits daily — was closed by Iran within days. Brent crude, which had been trading near $72 per barrel on the eve of the conflict, surged past $112 by late March, a rise of over 55 per cent in less than four weeks. The International Energy Agency characterised it as the greatest global energy security challenge in its history.
For investors in the Gulf and globally, the immediate instinct was familiar: sell equities, buy oil, hoard dollars. And in the first five weeks of the conflict, that trade appeared to be working. The S&P 500 fell approximately 8 per cent from pre-war levels, recording five consecutive weeks of declines — a streak that had occurred only twice in the prior 15 years. The MSCI All World ex-US Index fell more than 10 per cent over the same period. European gas benchmarks nearly doubled. Airlines, logistics companies, and consumer-facing businesses repriced sharply lower as energy cost projections spiralled.
GULF CONTEXT — A REGIONAL DISRUPTION WITH GLOBAL CONSEQUENCES
For GCC-based investors, this crisis carries particular weight. Tourism suffered as airspace closures disrupted travel. Gulf aluminium producers declared force majeure on some contracts following disruption to their operations. Qatar declared force majeure on LNG export contracts. The collective oil production from the GCC declined by an estimated 10 million barrels per day by mid-March. The region’s economic model — built on open straits, stable energy flows, and international connectivity — faced its most acute stress test in a generation.
And yet. By April 7, a two-week US-Iran ceasefire was announced. Markets responded with what analysts at JPMorgan described as euphoria returning to equities. The S&P 500 surged 2.5 per cent in a single session. The Dow recorded its largest one-day percentage gain since April 2025. By April 15, the S&P 500 closed above 7,000 for the first time in its history — having erased all war-related losses and then some. The rebound from trough to new all-time high was faster than the post-Covid recovery.
The investors who had sold in panic between late February and late March locked in real losses at precisely the wrong moment. Those who held — or added to positions at the late-March lows — participated in one of the sharpest recovery rallies in modern market history.
“The stock market is always trying to price what the world is going to look like six to twelve months from now.” — Joe Seydl, J.P. Morgan Private Bank, April 2026
Several dynamics underpinned this resilience that are worth understanding. First, the conflict — for all its severity on an energy and geopolitical level — did not fundamentally impair the earnings power of the US equity market’s largest constituents. Technology companies, which now account for nearly half of the S&P 500’s market capitalisation, were largely insulated from direct energy cost exposure. Second, investors had been conditioned by a decade of policy pivots: the so-called TACO trade — a sardonic market acronym for the observed tendency of the Trump administration to de-escalate when economic pain becomes politically costly — led many institutional players to hold positions or even add exposure during the drawdown. Third, the DXY, while firm during the conflict, did not spike dramatically as it had during Covid — suggesting that this was a regional energy shock being absorbed by a resilient domestic US economy, rather than a systemic financial panic.
HBZ CLIENT EXPERIENCE — PRUDENCE AS A COMPETITIVE ADVANTAGE
During the five weeks of maximum Iran war uncertainty, HBZ’s private banking teams across DIFC and Zurich maintained proactive communication with clients — not to offer predictions, but to provide structured context. Our advisors reviewed portfolio stress scenarios, reconfirmed risk tolerance profiles, and where appropriate, identified selective opportunities in quality assets that had been indiscriminately sold down. This is the HBZ philosophy made practical: in volatility, we do not step back from the conversation. We step forward into it. Prudence, in our experience, is not caution for its own sake — it is the discipline that preserves the optionality to act when others cannot.
Momentum versus fundamentals: A tale of two forces
It is worth being precise about what we mean by momentum and fundamentals, because the tension between the two is the engine of crisis investing.
Momentum is the tendency of assets that have been falling to continue falling — driven not by valuation but by the behaviour of other market participants. In a crisis, the feedback loop is self-reinforcing: prices fall, margin calls are triggered, forced sellers appear, prices fall further, and the headlines worsen. Technical levels that once provided support give way, and the narrative shifts from attractive buying opportunity to value trap.
Fundamentals, by contrast, are the slow-moving gravitational force of intrinsic value — the present value of a business’s future cash flows, its competitive position, its balance sheet. These do not change overnight because a virus emerged in Wuhan, a bank failed in Manhattan, or strikes were launched on Iranian nuclear facilities. Yet in crisis conditions, they are temporarily overwhelmed by the louder signal of fear. The 2026 episode illustrated this with unusual clarity: the underlying earnings power of US listed companies had not deteriorated materially, yet momentum sellers drove prices 8 per cent below pre-war levels in five weeks. Fundamentals then reasserted, violently, once the ceasefire catalyst arrived.
The investor’s task is not to be indifferent to crisis — real crises cause real economic damage, and distinguishing between temporary sentiment-driven dislocations and structural value impairment is genuinely difficult. The 2026 energy shock will leave lasting scars on European industrial capacity, on GCC economic confidence, and on global inflation trajectories. But the discipline of investing requires holding that distinction clearly in mind even when the world around you has abandoned it. This is the work that a private banking advisor, at their best, helps their client perform.
The dollar as a fear gauge
For investors in the GCC and wider emerging market universe, the US Dollar Index (DXY) carries particular relevance. A rising DXY is not simply a currency phenomenon — it is a barometer of global fear. When investors flee to safety, they buy US Treasuries, which requires buying US Dollars, which drives the DXY higher. Conversely, when risk appetite returns, the dollar softens, emerging market assets rally, and the carry trade revives.
In every major crisis episode in the table above, the DXY moved inversely to equities at the moment of peak distress. What was notable about the 2026 Iran conflict is that the DXY’s response was relatively muted compared to, say, the COVID-era strengthening of 3 per cent within a month — an anomaly for DXY. This suggested that institutional capital read the conflict as a geopolitical and energy shock — severe, but not systemic in the way that a credit freeze or pandemic is systemic. That reading proved correct. When oil began retreating after the ceasefire, the dollar softened, and the equity recovery was swift and broad.
For regional investors, this creates an actionable framework: when the DXY is spiking alongside falling equity markets, the conditions that historically precede a recovery are often assembling themselves quietly beneath the surface of the headlines. At HBZ, monitoring this relationship between the dollar, oil, and equity risk premium sits at the core of how we advise clients on portfolio positioning during periods of elevated geopolitical uncertainty — a skill that has particular resonance for investors whose wealth is anchored in the Gulf.
A framework for the disciplined investor
The lessons of history do not resolve to a simple buy-the-dip instruction. Not every drawdown is a buying opportunity; some reflect genuine structural deterioration. The discipline lies in a framework that distinguishes between the two — and in having an advisor who holds that framework steady on your behalf when emotion threatens to override it:
- Distinguish noise from signal. Ask whether the crisis has changed the earnings power or competitive position of the underlying businesses you own, or whether it has simply changed how others feel about them.
- Watch the DXY, not just the SPX. A DXY peak concurrent with an equity trough has historically marked the moment of maximum fear — and the inflection point of maximum opportunity.
- Maintain liquidity deliberately. Crisis-period opportunities are only accessible to investors who have not been forced to sell. Holding a pre-established cash allocation is not timidity — it is strategic optionality.
- Anchor to time horizon. The investor with a five-year horizon should be far less afraid of a six-week drawdown than the investor who has conflated their investment account with their emergency fund.
- Resist the narrative. Every crisis generates a dominant narrative that explains why this time is different. In 2026, it was the Strait of Hormuz — surely, the closure of the world’s most critical oil chokepoint would cascade into a permanent repricing of equities. It did not. Engage with it critically. The narrative is usually partially correct — and largely irrelevant to long-term returns.
The case for long-term patience
The data is not ambiguous. Since 1950, the S&P 500 has experienced 38 corrections of 10 per cent or more. Every single one has eventually been followed by a recovery to new highs. Morgan Stanley analysis found that over the past 75 years, the S&P 500 has risen an average of 8.4 per cent in the twelve months following a sudden external shock — whether war, pandemic, or energy crisis. The average recovery time for full bear markets has been approximately 27 months; for shallower shocks like the 2026 Iran episode, recovery was measured in weeks.
Fear is not irrational — it is a rational response to genuine uncertainty. What is irrational is allowing fear to masquerade as investment analysis. The investor who mistakes their anxiety for a market view, and acts upon it by selling quality assets at distressed prices, has done more damage to their long-term financial position than any market crisis ever could.
The history of markets is ultimately a history of human resilience. Companies adapt, economies recover, and capital — when allocated with discipline and patience — compounds. The Strait of Hormuz has been closed before. The oil price has surged before. The headlines have screamed unprecedented before. Each time, they were right about the severity of the immediate shock. Each time, they were wrong about its permanence.

The crises change. The pattern does not.
