LONDON, June 22 (Reuters) - The U.S. dollar remained well supported as investors balanced expectations of further Federal Reserve tightening against uncertainty surrounding negotiations aimed at securing a lasting peace agreement between the United States and Iran. The Japanese yen, meanwhile, hovered near a 40-year low, keeping markets alert for possible intervention from Japanese authorities.

Dollar Supported by Hawkish Fed Expectations

The dollar has been buoyed by expectations that the Federal Reserve could raise interest rates again this year following a hawkish shift under Fed Chair Kevin Warsh. Markets have increasingly priced in additional tightening as U.S. economic data continue to show resilience and inflation concerns remain elevated. The dollar index recently traded near the 101 level, close to its highest point in a year.

Strong labour market data and firmer growth expectations have reinforced the view that U.S. rates may stay higher for longer, supporting demand for the greenback.

Iran Talks Remain a Key Market Focus

Investor sentiment has also been influenced by developments in U.S.-Iran negotiations. Initial optimism surrounding a peace roadmap helped ease concerns over energy supply disruptions and pushed oil prices lower. However, uncertainty remains over implementation, with several planned negotiations delayed or cancelled and ongoing tensions in Lebanon complicating the outlook.

Markets are closely watching whether the talks can deliver a durable agreement, particularly because developments affecting the Strait of Hormuz have significant implications for global energy markets and inflation expectations.

Yen Under Pressure

The Japanese yen has remained under heavy pressure, trading around 161–162 per dollar and approaching levels not seen in roughly four decades. The currency's weakness reflects the widening gap between Japanese and U.S. interest rates, despite the Bank of Japan's recent rate increase.

Japanese officials have repeatedly warned that excessive currency moves are undesirable, and traders are increasingly speculating that further intervention could be considered if the yen weakens further. Japan previously intervened in the foreign exchange market when the yen approached similar levels.

Market Snapshot

• Dollar Index (DXY): Near a one-year high around 101.
• USD/JPY: Trading near 161–162 yen per dollar.
• Fed Outlook: Markets continue to price in a meaningful chance of another U.S. rate hike this year.
• Key Risk: Progress—or setbacks—in U.S.-Iran peace negotiations and their impact on oil prices and global inflation.

Outlook

For now, the combination of a hawkish Federal Reserve and lingering geopolitical uncertainty is supporting the dollar. The yen remains vulnerable unless Japanese authorities intervene more forcefully or U.S. rate expectations begin to ease. Meanwhile, developments in the U.S.-Iran peace process will continue to influence currency markets through their impact on energy prices and global risk sentiment.
