Cairo: Financial markets are facing renewed uncertainty as the United States prepares to introduce a major new round of economic sanctions against Iran, while Tehran warns that it could take steps that would further disrupt oil supplies from the Gulf.
The latest developments have created an unusual situation in global markets. Gold is climbing as investors look for protection from geopolitical and economic risks, while crude oil prices have moved lower after a strong rise last week. The mixed market reaction shows how uncertain investors remain about what the next stage of the US Iran confrontation will bring.
The United States is preparing what Treasury Secretary Scott Bessent has described as an exceptionally large financial campaign against Iran. The measures are expected to put greater pressure on Iran's trading partners and businesses involved in its economy. Washington wants to restrict the financial and commercial channels that allow Iran to continue earning revenue and conducting international trade.
The planned measures come after months of conflict and economic pressure between Washington and Tehran. Although direct military action has eased compared with earlier stages of the conflict, there has been little progress toward a lasting political settlement. The economic confrontation has therefore become one of the main ways Washington is attempting to pressure the Iranian leadership.
Iran has responded with strong warnings. Iranian officials have said that if the economic pressure continues, Tehran could take measures against oil exports from the Gulf. Such a move would raise concerns across the international energy market because the region remains one of the world's most important sources of crude oil.
The Strait of Hormuz is at the centre of these concerns. The narrow waterway is a major route for energy shipments from the Persian Gulf to international markets. Any serious disruption to shipping through the strait could increase the cost of transporting oil and fuel and could quickly affect countries far beyond the Middle East.
Oil markets have already shown how sensitive they are to the developments. Brent crude rose strongly last week after the United States warned that countries continuing to support Iran could face severe economic consequences. Brent reached around 94 dollars a barrel on Friday, marking a significant weekly increase.
However, oil prices moved lower on Monday as investors took profits and waited for details of the new American sanctions. Brent crude fell by more than one dollar, while US crude also declined. The fall does not necessarily mean that traders believe the risks have disappeared. Instead, investors are trying to assess whether the new sanctions will actually reduce Iranian oil supplies or lead to a wider confrontation that could eventually push prices much higher.
Gold has reacted differently. The precious metal climbed to more than 4,600 dollars an ounce, reaching its highest level in more than three months. Investors often turn to gold when they are worried about war, inflation, currency movements or financial instability.
The gold rally also reflects concerns that go beyond Iran. Investors are watching the US dollar, government bond yields, inflation and expectations about interest rates. These factors are adding another layer of uncertainty to financial markets at a time when geopolitical tensions are already high.
Stock markets have also come under pressure. Asian shares were mostly weaker on Monday as investors waited for the details of the US sanctions. Higher US Treasury yields are adding to the pressure because expensive borrowing costs can make shares less attractive and increase concerns about economic growth.
For consumers, the biggest concern is the potential effect on fuel and other essential goods. If the situation around the Gulf worsens and oil shipments are seriously disrupted, fuel prices could rise again. Higher transport and energy costs could then feed into food prices, manufacturing costs and household expenses in many countries.
At the same time, the current decline in oil prices provides some temporary relief. The market is clearly waiting for more information before deciding whether the latest US measures will create a lasting supply shock.
The coming days could therefore be important for both governments and financial markets. Washington is expected to provide more details about the sanctions, while Iran has made clear that it will not accept the new economic pressure quietly.
The latest developments show that the US Iran confrontation is no longer only a political or military issue. It has become a major economic story with consequences for oil, gold, currencies, shipping and global investment.
For now, investors are watching Washington and Tehran closely. A further escalation could send energy prices higher and increase demand for safe haven assets such as gold. Any sign of negotiations or reduced tensions, however, could have the opposite effect.
The direction of global markets will therefore depend heavily on what happens next around Iran, the Gulf and the Strait of Hormuz.
