The U.S. dollar hovered near multi-month lows on Monday as investors assessed the Treasury Department’s plan to increase purchases of long-dated bonds while awaiting new Iran sanctions and key central bank speeches.
The Canadian dollar weakened 0.2% to C$1.3798 per U.S. dollar after U.S.-Canada trade negotiations collapsed. Washington imposed 50% tariffs on Canadian goods, prompting Canada to retaliate with similar measures.
Elsewhere, the Australian dollar traded at $0.7166 and the New Zealand dollar at $0.5972, both close to three-month highs. The euro remained above $1.16 at $1.1680, while the Japanese yen stayed stronger than 159 per dollar. Sterling held firm at $1.3650, and the Chinese yuan hovered near a three-and-a-half-year high at 6.7232 per dollar.
Strong U.S. services data released Friday provided limited support for the greenback. The dollar still recorded its biggest weekly decline against Bitcoin in nearly three-and-a-half years and has also weakened sharply against gold.
Pressure intensified after 30-year Treasury yields approached two-decade highs. The U.S. Treasury responded by doubling long-end bond buybacks to $4 billion per operation. Although modest compared with the roughly $32 trillion Treasury market, the move raised concerns that policymakers could increasingly intervene to contain long-term yields.
Attention now turns to U.S. Treasury Secretary Scott Bessent, who is scheduled to detail new sanctions against Iran on Monday. Investors are particularly watching whether the measures will target China or other major Iranian trading partners.
Federal Reserve Chair Kevin Warsh’s Jackson Hole speech on Friday will also be closely monitored for clues about U.S. interest rates, Treasury yields and the Fed’s balance sheet.
In Japan, Bank of Japan Deputy Governor Ryozo Himino is scheduled to speak Thursday. Markets will watch for indications that the BOJ is moving closer to another interest rate hike, although U.S. bond-market developments are expected to remain the dominant driver of the USD/JPY exchange rate.
