USD strengthens on Trump tariff threats; CAD, JPY under pressure

The US dollar index gained 0.4% in early Asian trading, with USD/CAD surging 1.2% to 1.4450 after Trump announced a 35% tariff on Canadian imports effective August 1st. The aggressive trade stance has sparked broad dollar buying, pushing USD/JPY above 147.00 for the first time this week, gaining 0.8% to 147.25. Market participants view the tariff threats as potentially inflationary for the US, supporting hawkish Fed expectations. The Canadian dollar faces immediate pressure with support at 1.4500 likely to be tested, while the yen's weakness accelerated despite verbal intervention warnings from Japanese officials. Technical indicators show USD momentum building, with the DXY approaching resistance at 106.50. Traders are positioning for continued dollar strength as Trump's protectionist policies could force other central banks into defensive monetary easing, widening rate differentials in favor of the greenback.
