On August 20, 2026, President Donald Trump declared that the United States would subject Iran to “Economic Warfare,” warning of “tremendous consequences” for any entity engaging in trade with Tehran. This announcement came after months of military strikes and a maritime blockade had failed to compel Iran to capitulate. Trump did not specify the exact measures or countries that would be targeted, but his threat immediately brought China into focus, as it is a major buyer of Iranian oil. Following this declaration, Brent crude prices advanced for a fifth consecutive day, reaching approximately $94 a barrel, marking the highest point for the month.
In response to Trump’s comments, Beijing stated that sanctions and pressure would not be effective and called for a diplomatic resolution. Meanwhile, Iran commented on the new economic pressure. This move coincides with an ongoing disruption in global oil markets, partly due to the US naval blockade on the Strait of Hormuz and Iran’s retaliatory actions within the strait. The Strait of Hormuz, a critical shipping route for Middle Eastern oil, usually sees millions of barrels of oil and over 100 vessels daily, but recent reports indicate only about 12 ships transited on Wednesday. The UAE also announced a halt to all trade with Iran due to attacks from the Islamic Republic.
Simultaneously, global bond yields experienced a decline after the US Treasury revealed plans to buy back more longer-dated bonds, an intervention by Scott Bessent prompted by borrowing costs reaching multi-year highs. Hours later, data showed that total US public debt had surpassed $40 trillion for the first time. In other market news, Novonesis, a Danish biotech company, saw its shares jump over 10% after announcing its first-ever share buyback program worth €1 billion, following a second-quarter revenue that exceeded estimates and an upgraded full-year revenue guidance. Target also boosted its sales outlook, contributing to a buzz in Europe's hot stock markets.
