The dollar had been on a tear. Then it stopped.
Buyers got the first real sign of progress on a US-Iran deal. Risk appetite came back.
That is usually bad news for the world's safest currency.
The Bloomberg Dollar Spot Index ticked up Friday. The dollar ended the week roughly flat.
That sounds dull. But it broke a run that had carried the index near a six-week high.
The pause came after Marco Rubio spoke. He said there had been "some good signs" in the latest round of talks with Tehran.
Currency desks read that as a small but real shift. Stocks read the same news and rallied.
US stocks pushed toward their longest streak of weekly gains since 2023. Oil prices bounced around as traders tried to guess if a deal would cool tensions in the Strait of Hormuz.
The split between stocks and the dollar is the part worth watching. It shows the market is leaning toward peace without fully pricing it in.

Washington and Tehran are still apart on two key issues. Iran's uranium stockpile is one.
Who controls the Strait of Hormuz is the other. "Some good signs" is not a signed deal.
Currency desks treated it like the soft signal it is. The Fed is sitting in the background too.
Strong US jobs data has pushed traders to bet on fewer rate cuts this year. That keeps the dollar held up even when risk appetite picks up.
Higher rates mean higher yields - the interest a bond pays. That pulls money into dollar-denominated assets.
It is the slow gravity that has been holding the dollar up. So the week ended with two forces pulling against each other.
Peace hope pushed the dollar down. Fed bets held it up, and the two roughly canceled out.
That is why the index ended where it started.
The next move depends on whether the talks produce something real. Mixed messages can only support stocks for so long.
The math has to back up the mood. If the Iran war cools, expect the dollar to slip and risk assets to keep running.
If talks fall apart, the dollar likely runs back to recent highs. Stocks would give some of the rally back.
For buyers of US stocks, the trade has been simple this month. Risk-on names rally on hope, then pull back when talks stall.
For buyers of foreign stocks, a weaker dollar would help. It lifts the value of foreign earnings when they get pulled back into dollars.
Either way, the dollar is the cleanest read on which way the market thinks talks are heading. It moves faster than stocks and tends to lead.
The next thing to watch is whether Iran agrees to inspections of its uranium stockpile. That would be the first hard step toward a deal.
Until then, expect more weeks like this one. Big moves at the open, flat by the close.
