Markets do not lie. They translate fear, uncertainty, risk. Right now, they are screaming.
On 23 July 2026, Wall Street experienced a dark day. The Nasdaq fell by 2.15%. The S&P 500 by 1.21%. The Dow Jones lost more than 500 points. The Magnificent Seven, those tech giants that were carrying the market at arm’s length, saw 900 billion dollars in market capitalisation go up in smoke in a single session. Tesla plunged by 14.5%. Alphabet by 7%. Amazon by 4.5%.
This is not an accident. It is the financial translation of a world at war.
Oil, the Nerve of War
Brent crude crossed the 100 dollars a barrel mark on 23 July, a first for two months. It climbed 11% in a week. WTI followed, at nearly 90 dollars. The reason is simple: the two main energy chokepoints on the planet are under threat.
The Strait of Hormuz is virtually closed. Twenty percent of the world’s oil transits through it every day. The IRGC has stopped three tankers attempting to force the passage. Six thousand sailors are stranded aboard four hundred ships.
The Strait of Bab-el-Mandeb is under threat from the Houthis. Two Saudi tankers have already been hit. If both corridors were to close simultaneously, more than a quarter of the world’s supply would disappear.
An analyst at deVere Group sums up the situation with chilling sobriety: “Two of the world’s busiest shipping corridors are threatened in the same month, and markets are only beginning to understand what that means.”
Traders are now preparing for a barrel at 120 dollars in the event of an escalation this weekend. American diesel has already crossed the 5 dollars a gallon mark. Petrol is following.
Tech, the Collateral Victim
The artificial intelligence bubble is deflating. And it is no coincidence that it is happening now.
The quarterly results of Tesla and Alphabet revealed a truth that the markets refused to see: AI burns cash with no immediate return. Tesla announced its first cash consumption in two years. Alphabet saw its capital expenditure soar by 15 billion dollars, with a negative free cash flow of nearly 6 billion.
A portfolio manager at Algebris Investments warns: “The valuations of American equities are exorbitant despite the low cash flows generated by tech. This is a market that is showing signs of a bubble.”
When oil rises and rates climb, promises of a brighter tomorrow are no longer enough. Investors want concrete results. And concrete results, today, are war, inflation, and uncertainty.
Rates, the Ultimate Sanction
American 10-year bonds have reached 4.71%, their highest level of the year. The 30-year has touched 5.17%, a level not seen for nineteen years. In Germany, the 10-year Bund has risen to 3.21%, the highest since 2011.
Markets are anticipating a rate hike by the Federal Reserve. Most banks consider it likely before the end of 2026. The ECB is expected to make a move in September. The prospect of sustained energy inflation is pushing central bankers to tighten the screws.
The yen, meanwhile, is collapsing. At 163.8 yen to the dollar, it is at its lowest since 1986. The US Treasury has warned that “excessive currency volatility was undesirable.” Japan could be forced to intervene.
The Dollar, Refuge or Trap?
The dollar is rising. It is the classic reflex in times of war. Capital flees conflict zones and takes refuge in the American currency. The Dollar Index is at its monthly high.
But this strength is a symptom, not a remedy. A strong dollar penalises American exports, increases the cost of debt for emerging countries, and complicates life for multinationals. It attracts capital, but it solves nothing.
Gold, paradoxically, is falling. At 4,047 dollars an ounce, it has lost 2%. The reason? A strong dollar and high rates overshadow its safe-haven status. Even gold is no longer reassuring.
Customs Duties, the Final Blow
As if war and soaring oil prices were not enough, Washington imposed new customs duties on 23 July. Ten to twelve and a half percent on imports from sixty countries. A measure that covers 99.4% of all American imports. The European Union is threatening retaliation.
It is a trade shock added to the energy shock and the technological shock. A perfect storm.
The Scenarios
Markets are fragile, but not yet in a systemic crisis. The real test will be the reaction of financial markets if Brent durably crosses 110 or 120 dollars.
Military escalation this weekend could cause a shock on Monday, with closed markets unable to integrate the information in real time.
Tech could continue to correct. The Magnificent Seven lost 900 billion in a single day. If the results of the other giants disappoint, the purge could intensify.
Central banks could be forced to choose between fighting inflation and supporting growth. An impossible dilemma.
The Iran-United States war has become a global economic war. The battlefields are no longer only in the Persian Gulf. They are on Wall Street, in Frankfurt, in Tokyo. Markets are the thermometer of the conflict. And the fever is rising.
