Dollar Index Holds Near 13-Month High as Fed Hawks Battle Iran Deal Optimism

The US Dollar Index (DXY) continued to hover around 101.00 during Asian trading hours on Tuesday, staying within striking distance of its 13-month peak of 101.13 reached on June 19. The greenback's resilience is underpinned by a hawkish Federal Reserve repricing, even as easing geopolitical tensions apply modest headwinds.

Fed Repricing Drives Dollar Support

The Federal Reserve held its benchmark rate steady at 3.50%–3.75% at its June meeting, but the tone struck by newly appointed Fed Chair Kevin Warsh proved more hawkish than markets anticipated. According to the CME FedWatch Tool, fed funds futures have now fully priced in a 25-basis-point rate hike for September, with a marginal probability of action as early as July also appearing on the radar.

For Southeast Asian traders, a prolonged hawkish Fed stance keeps the dollar bid and sustains capital outflow pressure on regional currencies such as the Indonesian Rupiah (IDR) and Philippine Peso (PHP) — both of which have already felt depreciation stress in recent weeks.

Iran Talks Inject Cautious Optimism

Dollar gains are being capped, however, by progress in US-Iran nuclear negotiations. US Vice President JD Vance told CNBC on Tuesday that talks have achieved "great progress," even as friction persists. On Monday, Vance confirmed Iran had agreed to readmit International Atomic Energy Agency (IAEA) inspectors — a significant de-escalation step. Iranian Foreign Minister Abbas Araghchi separately confirmed via Swiss-mediated channels that discussions had produced "major progress."

A sustained diplomatic breakthrough could ease oil supply concerns, soften inflation expectations, and ultimately reduce the urgency for further Fed tightening — creating a two-sided constraint on dollar momentum.

Key Levels to Watch

DXY is consolidating within the 100.80–101.13 range. A clean break above 101.13 opens the path toward the 102.00 psychological resistance. Traders should closely monitor this week's US PCE inflation data and weekly jobless claims, which could either reinforce or unwind September hike expectations.

Trader Takeaway: The dollar's near-term bias remains tilted to the upside on Fed hawkishness, but Iran deal progress and improving risk sentiment may limit gains. Watch incoming US macro data for directional confirmation.
