Dollar steadies, set for weekly loss on US-Iran deal talks

The dollar steadied Friday. It is still on track for a weekly loss as reports of progress in US-Iran nuclear talks weighed on the currency. A deal would lift sanctions on Iranian crude exports, adding supply to a market already under pressure from OPEC+ production increases.

Lower oil prices cut US gasoline costs and dampen inflation expectations. That gives the Federal Reserve more room to ease policy, which in turn drags the dollar lower. The logic is straightforward: cheaper oil reduces the need for tight monetary policy.

The euro and yen both gained ground this week. Commodity currencies such as the Canadian dollar also rose, helped by the prospect of cheaper crude. The Australian dollar lagged as iron ore prices slipped.

Treasury yields dipped on the week, with the 10-year note falling back toward 4.50%. Lower yields further reduce the dollar's carry advantage. The dollar index is down roughly 0.8% from Monday's close.

The next catalyst is the formal timeline for nuclear negotiations. No date has been set for resumption. Until then, the dollar may hold near current levels, with the next move driven by oil prices and Fed commentary.

Traders are also watching producer-price data due next week. A soft PPI print would reinforce the disinflation narrative and keep the dollar under pressure. A hot number, by contrast, could pause the slide. For now, the path of least resistance is lower.
