Why are oil prices down by 10% and US stock market indexes, Dow Jones, S&P 500 and Nasdaq, up now? This question became central after oil prices dropped sharply and stock markets surged worldwide. Iran announced that the Strait of Hormuz is open for commercial vessels during a ceasefire period. This news reduced fears of a global energy shock. Investors responded by buying stocks and selling oil. The Dow Jones surged by more than 1,000 points, and the S&P 500 and Nasdaq also gained. The developments came during ongoing diplomacy between the United States and Iran. Markets are now watching whether the ceasefire and talks will continue.

Why are oil prices down by 10% and US stock market indexes, Dow Jones, S&P 500 and Nasdaq, up now?

Oil prices dropped after Iran announced that the Strait of Hormuz is open for commercial ships. This waterway carries about one fifth of the world’s oil and liquefied natural gas. During the conflict, the passage was blocked, which raised fears of supply disruption.

After the announcement, U.S. crude fell 10.2% to $81.88 per barrel. Brent crude fell 10.3% to $89.09. Oil prices remain above pre-war levels near $70. Markets still price in some risk. Stock markets rose at the same time. The Dow Jones Industrial Average jumped by more than 1,020 points. The S&P 500 climbed about 1.3%. The Nasdaq rose about 1.5%. Stocks have risen about 12% since late March due to hopes that the conflict may not worsen.

Why are oil prices down by 10%?

The main reason is the reopening of the Strait of Hormuz. Iran’s foreign minister said the passage is open for commercial vessels during the ceasefire. This reduces fears of a major supply shock. Oil prices had surged earlier because the conflict disrupted shipping. When supply risks fall, oil prices often fall.

The reopening came after a ceasefire between Israel and Lebanon. The truce reduced fears of wider regional conflict. Investors reacted quickly by selling oil. However, shipping companies remain cautious. Some firms said they will wait before resuming normal transit. They want clarity on safety and possible sea mines.

Why are US stock market indexes, Dow Jones, S&P 500 and Nasdaq, up now?

Stock markets rose because lower oil prices reduce inflation pressure. Lower inflation means central banks may avoid raising interest rates further. This supports stocks. Companies with high fuel costs gained the most. Airlines and cruise operators rose sharply. United Airlines jumped 9.8%. Norwegian Cruise Line and Royal Caribbean rose 9.3%.

Financial companies also reported strong earnings. State Street rose 2.9%. Fifth Third Bancorp gained 1.4%. Stocks have also been supported by hopes of diplomacy between the United States and Iran. President Donald Trump said the war may end soon. He said many points of a deal are already negotiated.

Is Strait of Hormuz fully open now?

Iran said the Strait is open for commercial vessels during the ceasefire. Only civilian ships can pass through designated routes. Military vessels are still restricted. The U.S. Navy blockade of Iranian ports remains in place. It will continue until a final deal is reached. Shipping companies remain cautious. Some said they will wait before resuming normal traffic. Before the war, about 130 ships passed daily through the Strait.
