Dollar Weakens Amid Hopes of Iran Nuclear Agreement, Japanese Yen Nears Vulnerable Territory

Dollar Retreats as Hopes Rise for US Deal with Iran

The U.S. dollar retreated from a six-week high on Wednesday, May 20, as rising hopes of a deal between the U.S. and Iran to end the war in the Middle East led to a decline in Treasury yields and a subsequent dent in the dollar. The greenback is a safe-haven investment that is correlated with yield moves, and its value is influenced by the yield on U.S. Treasury bonds.

U.S. President Donald Trump's statements on Wednesday regarding the final stages of negotiations with Iran, while warning of further attacks unless a deal is reached, contributed to the decline in Treasury yields. This, in turn, dented the value of the dollar. Marc Chandler, chief market strategist at Bannockburn Global Forex, noted that the dollar was approaching technical levels that suggested some giveback was due. This includes seven consecutive down days for the yen against the U.S. currency, the longest stretch since October.

Growing Concerns Over War-Related Inflation

Concerns are growing that inflation linked to the war may become more entrenched in core consumer spending, driving expectations of higher interest rates and a more hawkish stance from central banks. Benchmark 10-year U.S. Treasury yields reached a 16-month high on Tuesday, while 30-year yields hit their highest level since 2007.

Fed Rate Hike Support Builds

Minutes from the Fed's April meeting on Wednesday showed a growing number of officials said the central bank should lay the groundwork for a possible rate hike, a sign that incoming Chair Kevin Warsh will inherit an increasingly hawkish crew of central bankers. Fed funds futures traders are pricing in roughly 50% odds that the Fed will raise rates by January, a sharp reversal from before the Iran war began in late February, when markets had expected two cuts this year.

Accelerating economic growth has reinforced expectations of higher rates, while a resilient labor market has reduced the case for cuts. Trump acknowledged in an interview with Fortune magazine published on Monday that he may need to wait until the war with Iran concludes before rate cuts become feasible.

Currency Market Reaction

The dollar index, which measures the greenback against a basket of currencies including the yen and the euro, fell 0.21% to 99.10, with the euro up 0.21% at $1.1628. Sterling strengthened 0.37% to $1.3442. The Australian dollar, often seen as a barometer for risk sentiment, gained 0.63% versus the greenback to $0.5871.

Yen Vigil Returns

The dollar's recent rise has pushed the yen back toward the 160 level that prompted Japanese officials last month to launch their first currency market intervention in nearly two years. The Japanese yen was last up 0.14% against the greenback at 158.82 per dollar. Marc Chandler noted that "we're waiting for the Japanese response. We're fishing for their pain threshold."
