Persian Gulf crisis drives oil prices
In March 2026, the global energy supply is under the impact of an escalating military conflict in the Middle East between the USA, Israel and Iran. The conflict puts key trade routes and important production regions at risk and is causing considerable uncertainty on the global energy markets. The focus is particularly on international oil trade flows, as the energy sector relies on stable supply chains and geopolitical risks have a direct impact on commodity markets.
Strategic importance of the Strait of Hormuz
A key reason for the strong market reaction is the strategic importance of the Strait of Hormuz as one of the most important transportation routes for crude oil and other energy products. The narrow strait between the Persian Gulf and the Gulf of Oman is the main sea route for the export of oil from the region's major producing countries, including Saudi Arabia, Iraq, Kuwait, the United Arab Emirates, Qatar and Iran itself.

According to international energy data, around 20 million barrels of oil pass through the Strait of Hormuz every day, around a fifth of the oil traded worldwide. In addition, a significant proportion of the global liquefied natural gas (LNG) trade is handled via this route. This high concentration shows how sensitively supply can react to disruptions, as restrictions in shipping traffic or increased risks have a direct impact on global oil supply and pricing.

Developments in the Persian Gulf
The situation in the Persian Gulf has deteriorated significantly since the end of February 2026. In the course of the military disputes between Iran, the USA and Israel, Iranian forces began to obstruct merchant ships and tankers passing through the Strait of Hormuz. According to maritime reports, several ships received radio instructions from the Iranian Islamic Revolutionary Guard Corps (IRGC) stating that "no ship is allowed passage", prompting many shipping companies to turn back, remain at anchor or choose alternative routes.
Officially, Iran has not declared a legally binding blockade, but actual ship movements show a significant decrease in traffic through the strait. Many shipowners and insurers are avoiding the region due to the high risks, and numerous tankers and freighters are anchored in front of or behind the strait, while states and companies are suspending their transit plans out of caution.

This development represents an extraordinary disruption to one of the world's most important oil transportation routes, as this sea route is normally used to ship large portions of oil exports from the Persian Gulf to Asia, Europe and North America.
Reactions of the international oil markets
The disruption of the Strait of Hormuz immediately led to strong reactions on the international oil markets and a significant rise in oil prices. The uncertainty about future developments was enough to drive up oil prices, as the market reacts sensitively to risks that could jeopardize global supply. In such situations, market participants factor in so-called geopolitical risk premiums, which increase the price even if there have not yet been any large-scale actual supply disruptions.
Another important factor is the expectation of future supply bottlenecks. Traders who assume that less oil could be available increase their demand in advance in order to secure stocks, which further increases the price increase. At the same time, futures markets are also reacting to the situation as investors speculate on further price rises. (Reuters, 01.-02.03.2026)
Impact on the global economy and consumers
Rising oil prices are also having an impact on other areas of the economy worldwide. Higher crude oil prices lead to rising costs for fuels such as petrol, diesel and kerosene. This increases transportation costs, which affects the prices of many goods, as transportation is a key component of global supply chains. This can contribute to a general rise in price levels and further increase inflation. (AP News, 02.03.2026)
