Certainly, the price of oil would be higher today if markets were open, as Iran's action suggests that shipping in the Persian Gulf and Strait of Hormuz could be affected. This could result in a global increase in oil prices, considering that this region is one of the world's main oil producers. If the price of oil continues to rise like this, it will be a negative sign for the financial markets and also for cryptocurrencies. A prolonged rise in oil prices tends to drive inflation, which in turn could lead the United States central bank to keep interest rates high. Although nothing concrete has happened yet, it is important to remember the impact of the oil crisis in the 1970s.
