The U.S. dollar struggled to hold onto gains against major peers on Tuesday, as investors parsed Washington's expanded Iran-related sanctions and renewed efforts to ease pressure on longer-dated Treasury yields. The euro was a shade higher at $1.1668, hovering near a three-month peak hit last week, while sterling was 0.1 per cent stronger at $1.3639, near its six-month peak.

Why it matters

The U.S. dollar's performance is crucial for global trade and finance, and the impact of Iran sanctions and Treasury buybacks on the dollar's value is significant.

Imagine you have a big jar of cookies, and you want to keep them safe from getting eaten. But someone else comes along and says, 'Hey, I'm going to take some of those cookies!' You might feel a little worried that your cookies are going to get eaten. That's kind of like what's happening with the U.S. dollar right now. Some people are worried that the dollar is going to lose its value, and that's making them a little nervous.

Analysis

U.S. Dollar Struggles to Hold Gains Against Major Peers

The U.S. dollar struggled to hold onto gains against major peers on Tuesday, as investors parsed Washington's expanded Iran-related sanctions and renewed efforts to ease pressure on longer-dated Treasury yields. The dollar index, which measures the U.S. currency against six major peers, was down marginally at 98.96 in Asia trades.

The euro was a shade higher at $1.1668, hovering near a three-month peak hit last week, while sterling was 0.1 per cent stronger at $1.3639, near its six-month peak. The Canadian dollar held flat at $1.3844, steadying after a 0.6 per cent dip in the previous session, as the U.S. threatened to raise tariffs on Canadian goods after trade negotiations collapsed.

The Japanese yen strengthened a tad to 159.21 per dollar, having given back most of its intervention gains but still well off a multi-decade low of about 164. The dollar index, which measures the U.S. currency against six major peers, was down marginally at 98.96 in Asia trades.

Treasury Yields Ease, But Relief Limited

Treasuries found some support after CNBC reported that the U.S. Treasury could use part of its cash balance to buy back longer-dated bonds in an effort to ease borrowing costs. However, the relief was limited. The yield on the 2-year note, which typically moves in step with expectations for Federal Reserve interest rates, was flat at 4.246 per cent, while the yield on benchmark U.S. 10-year notes was at 4.704 per cent.

Market Participants Await Federal Reserve Chair's Speech

Market participants are also awaiting Federal Reserve Chair Kevin Warsh's debut speech in Jackson Hole, Wyoming, on Friday, as traders seek clues about the recent jump in bond yields and reassurance about his independence from the Trump administration. "Uncertainty over the Fed's reaction function, coupled with growing doubts about its commitment to prioritising inflation, has sharpened attention on Chair Warsh's upcoming remarks at Jackson Hole," Sim Moh Siong, FX strategist at OCBC, wrote in a note.

Key points

  • The U.S. dollar struggled to hold onto gains against major peers on Tuesday.
  • Investors parsed Washington's expanded Iran-related sanctions and renewed efforts to ease pressure on longer-dated Treasury yields.
  • The euro was a shade higher at $1.1668, hovering near a three-month peak hit last week.
  • Sterling was 0.1 per cent stronger at $1.3639, near its six-month peak.
  • The Canadian dollar held flat at $1.3844, steadying after a 0.6 per cent dip in the previous session.
The Upside

If the U.S. Treasury's efforts to ease pressure on longer-dated Treasury yields are successful, it could lead to a decrease in borrowing costs and a strengthening of the U.S. dollar. Additionally, if the Federal Reserve Chair's speech in Jackson Hole provides reassurance about the central bank's commitment to prioritizing inflation, it could also help to stabilize the dollar.

The Downside

However, if the U.S. Treasury's efforts to ease pressure on longer-dated Treasury yields are unsuccessful, it could lead to a further increase in borrowing costs and a weakening of the U.S. dollar. Additionally, if the Federal Reserve Chair's speech in Jackson Hole fails to provide reassurance about the central bank's commitment to prioritizing inflation, it could also lead to a further decline in the dollar.
