The U.S. dollar finished the week near a two-month high as Treasury yields surged and markets raised the odds of another Federal Reserve rate increase. The dollar index, which tracks the greenback against a basket of major peers, climbed more than 1% on the week and traded around 101.2 after touching about 101.4 midweek — its strongest level since late July, Reuters and CNBC reported.

That firmness rests on a rate-differential bid. The Fed raised its policy target by a quarter point on Sept. 16 to a 3.75%–4.00% range, its first hike in three years. Long-dated Treasury yields then pushed to multi-decade highs, lifting the return on dollar assets relative to Europe and Asia. The euro slipped to about $1.137, a two-month low, and headed for a third weekly decline. Sterling hovered near a three-month low around $1.32. The yen stayed soft near 158–159 per dollar after markets judged the Bank of Japan's latest hike as not hawkish enough, though fresh Tokyo warnings about intervention kept traders cautious.

Fed speakers kept an October move in play. Philadelphia Fed President Anna Paulson said some modest further tightening may be warranted. New York Fed President John Williams said another hike may be appropriate by year-end. CME FedWatch odds for an October increase rose into the high-60% to near-70% range from the mid-50s a week earlier, both outlets said.

Higher U.S. yields make holding dollars more attractive when peers are easing less — or hiking into weaker growth. That relative policy edge is why the greenback stayed bid even as oil prices and geopolitics swung day to day. Emerging-market currencies remain the pressure valve if the next U.S. inflation or jobs prints come in hot and lock in another hike.

What comes next is the data that can cement or trim that edge. Investors are watching the next inflation and employment reports ahead of the Fed's October meeting. A hot run would likely keep the rate differential — and the dollar bid — intact. Softer prints could pull front-end yields lower and ease pressure on the euro and yen.

For households, the same yield climb that supports the dollar also lifts borrowing costs tied to Treasuries, from mortgages to other rate-sensitive loans. The FX story and the household rate story travel together until the next public inflation and payrolls tests land.

Reuters and CNBC agree the weekly advance rested on higher Treasury yields and firmer Fed-hike bets after the Sept. 16 move. They differ on how far the rally can run: CNBC quotes ANZ's Khoon Goh warning that U.S. fiscal and policy uncertainty has limited further dollar gains even as yields climb, while Reuters' market voices framed midweek strength as traders simply following multi-decade yield highs against softer European and Japanese currencies.
