The US dollar rallied to its highest level since March 2020 on Monday and is on track for its best month since January 2015, buoyed by expectations that the Federal Reserve will have to lift interest rates aggressively to tame inflation.
The dollar index, which tracks the US currency against six others including the euro and sterling, rose by as much as 0.8 per cent to a high of 101.86. The index has risen roughly 12 per cent in the past year.
The gains come at a time when the Fed is expected to tighten policy more aggressively than other G-10 central banks. The higher interest rates, and higher yields on US government debt, have lured foreign investors into US Treasuries. The value of the dollar rises as investors sell holdings denominated in local currencies in favour of dollar-denominated investments.
