The greenback is at a multi-month high. The question for the week ahead is whether higher yields are driving it, or whether it’s mainly a weak euro.
The dollar has had a strong month. The US Dollar Index (DXY), which tracks the dollar against a basket of major currencies, climbed to its highest since April 2025, while the euro slid towards $1.12, a 17-month low.
The index is trading around 102.3, just below its 102.54 peak.1
On the surface the story looks simple. The Federal Reserve (Fed) raised rates to 3.75–4.00% on 16 September in a 12–0 vote, and its median projection now points to another hike this year and no cuts next year.2 Higher rates usually mean a stronger currency.
So where’s the dilemma?
The vote was unanimous, and the minutes show every policymaker backed it, but there was more debate about why. Some officials saw the hike as insurance against energy and other supply shocks spreading through the economy, while others thought stronger demand already justified higher rates.3 Markets are already leaning towards a pause: prediction market Polymarket puts the chance of no change at the 27–28 October meeting above 80%, in line with CME FedWatch.4
Singapore’s DBS and Dutch bank ING disagree on what comes next. DBS warns the dollar’s rally is losing support from interest rate policy as senior Fed officials push back on an October hike. ING still sees room for a move towards 102.85, helped by euro selling.5
The DXY isn’t a pure dollar gauge because the euro makes up 58% of the basket.6 If the move is mostly a European problem, traders could be overestimating dollar strength. A cleaner read could come from the dollar-yen exchange rate (USD/JPY), which is holding near 158,6 or from a basket of commodity currencies (those of major raw-material exporters).
This one matters most. The 10-year Treasury yield hit 5.349% on Monday 5 October and reached as high as 5.365% on Wednesday, its highest level since 2002, before easing back to 5.24% by Friday.7 If yields are rising because the US economy is strong, that supports the dollar. If they’re rising because investors want more compensation for holding US debt (known as a rising term premium), that’s a warning sign. Part of the bond sell-off has been driven by ballooning government debt.8
The first case attracts capital to the US. The second can eventually push it away.5

The dollar's strength is real, but it rests on several different drivers. Traders who know which one is in charge on a given day may be better placed than those who only follow the headline number.
