Gas prices in Europe have increased significantly, approximately 60%, since the beginning of the war due to Iran's closure of the Strait of Hormuz, a critical passage that facilitates roughly 20% of the world's liquefied natural gas (LNG) supply. This strait is particularly significant for Europe, which relies on it for about 15% of its gas consumption, and it also transports about 30% of the world's oil. Normally, around eighty tankers and LNG ships transit the strait daily, but the area currently remains empty as vessels await resolution of the escalating situation.

In addition to closing the strait, Iran has launched attacks on oil refineries in Saudi Arabia, Kuwait, and the United Arab Emirates, as well as a liquefied natural gas facility in Qatar, leading to Qatar temporarily halting production. Such actions have deepened concerns regarding energy supply stability in a region already fraught with tension. The geopolitical ramifications of these developments are significant, as they threaten to disrupt global energy markets and lead to potential price surges higher than those experienced following Russia's invasion of Ukraine.

The consequences of interruptions to oil and gas flows through the Strait of Hormuz are dire for global economies, as indicated by current market reactions. Although prices have risen recently, they have not skyrocketed to the levels observed immediately after the Russian invasion of Ukraine. Nevertheless, should the situation escalate further, we could see a dramatic increase in energy prices, impacting not just Europe but the broader international market, underscoring the vital importance of the region in global energy supply chains.
