Bessent announces sanction campaign against Iran. Treasury Secretary Scott Bessent today outlined a plan to economically isolate Iran, vowing to “sever every economic pipeline” until Tehran “stands alone.” The sanctions aim to cut off “five of Iran’s most vital lifelines that it exploits in other countries: digital assets, technology, gold, aviation and shipping.” Bessent also warned that any country continuing to support Iran would face US penalties, though no specific measures were announced. Iranian Economy Minister Ali Madanizadeh downplayed the threat, saying Iran is “fully prepared for this economic war.”
Canada to impose reciprocal tariffs as US trade talks collapse. Canadian negotiators left Washington on Friday without a deal to prevent President Trump’s 50% tariffs on Canadian goods. The levies, which took effect on Saturday, cover an estimated $20 billion of exports ranging from wine and hockey sticks to cement. Both sides have blamed the other for the breakdown, as US Trade Representative Greer said today that negotiations fell apart after Canada “wanted more,” while Canadian Prime Minister Carney cited “last-minute changes,” from the White House. Canada has since announced $20 billion in reciprocal tariffs on US steel, dairy, electronics, and appliances, set to take effect September 8. The Canadian dollar fell as much as 0.6% on the news.
