Stock markets: $11.5 trillion turned to ash. The once safe havens are gone; oil hit them all

In a single month, the markets saw $11.5 trillion disappear—not because of an impending crisis, but because of the war that suddenly broke out and changed everything. The first quarter of 2026 ended with a violent reversal: everything that was considered safe collapsed.

March wasn't just a bad month for the stock market. It was a brutal revaluation of the world market. Global market capitalization fell from $157.5 trillion to $146 trillion in a few weeks, a clear illustration of how quickly wealth can evaporate when geopolitics invades the economic narrative, the Greek press writes.

The first reaction was almost instinctive. Within 48 hours of the start of the conflict, $3.2 trillion had been wiped from global markets. Sessions reminiscent of other times followed: a trillion dollars disappeared in a single day in mid-March, while a similar amount was lost again on the 26th of the month. This was not a gradual correction, but a sequence of “shocks” that pushed investors from one revision to another.

For the quarter as a whole, the picture is equally telling. The MSCI World Index lost about $7 trillion, confirming that March not only absorbed the gains of previous months, but completely reversed the mood in the market. What until February looked like a year of general growth turned into a defense and loss management scenario.

Shock from Asia to New York

On Wall Street, the reversal was particularly sharp. The S&P 500 index lost more than $5 trillion in market capitalization in a single month, while all three major indexes (S&P, Dow Jones, Nasdaq) had their weakest quarter in four years.

The momentum that had begun to build—the rise extending beyond the big tech companies—suddenly “froze.” The market is no longer concerned with who will gain from growth, but who will withstand the shock.

In Europe, energy dependence has proven to be a weak point. The STOXX 600 fell nearly 8% in March, posting its biggest decline since 2022 and ending an impressive eight-month winning streak. European markets started the month near record highs, but rising energy prices and fears of an economic slowdown quickly changed the picture.

Asia felt the shock even more acutely. Emerging markets, which are heavily dependent on energy imports, have been hit hard. The MSCI Asia index fell 14 percent in March, its biggest drop since 2008, while currencies hit multi-year lows as rising oil prices hurt balance sheets and boosted demand for dollars.

Oil, the arsonist of the market

At the center of all this is oil. The significant disruption to the flow through the Strait of Hormuz – a hub through which about a fifth of global supply passes – has caused a historic surge in prices.

The price of Brent crude rose by about 86% (quarter/quarter), while US light crude oil (WTI) ended the quarter with gains of 79%.

Prices above $100 now act as an informal tax on the global economy, affecting everything from transport costs to food and industrial production.

This energy shock had direct consequences on other markets as well.

Bonds and Gold

Bonds, traditionally a safe haven, have not provided the expected protection. Yields soared in March as investors believed inflation could remain high for longer. The classic 60/40 portfolio fell almost as much as stocks, underscoring the extent of the turmoil.

Even more striking was the behavior of gold. Instead of consolidating, it fell more than 13% in the month – its worst performance since 2008. The market no longer sees the conflict as just a geopolitical event, but primarily as an inflationary shock that keeps interest rates high and limits the attractiveness of non-performing assets.

After all, the first quarter of 2026 wasn't just a period of losses. It was a moment of transition. Markets have shifted from the optimism of economic growth and lower interest rates to a new regime dominated by energy, geopolitics and inflation.

And in this new landscape, one thing is becoming increasingly clear: bombs don't just change maps. They change markets.
