The dollar dilemma: why a strong dollar may not be what it seems
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 setup
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.
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. Higher rates usually mean a stronger currency.
So where’s the dilemma?
Dilemma 1: a united vote, but a divided board
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. 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.
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.
Dilemma 2: is this dollar strength, or euro weakness?
The DXY isn’t a pure dollar gauge because the euro makes up 58% of the basket. 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, or from a basket of commodity currencies (those of major raw-material exporters).
Dilemma 3: good yields vs bad yields
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. 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.
The first case attracts capital to the US. The second can eventually push it away.

The Week Ahead: Five Signals That Could Move the Dollar
Key levels, inflation, Fed expectations and oil prices: what traders should watch.
- US Dollar Index (DXY) – Can the dollar break higher? ING sees 102.85 as a potential upside target. Watch whether the index holds above 102 for signs of continued strength.
- US 10-year yield – Will bond yields revisit their highs? After briefly exceeding 5.35%, a renewed rise could support the dollar through higher rate expectations or weigh on sentiment if driven by fiscal concerns.
- US CPI (Wednesday 14 October) – Will inflation revive October hike bets? Headline inflation is expected to rise to around 3.6–3.7% from 3.4%, mainly on energy prices, with core forecast at 0.2% on the month. A core reading of 0.3% or more could revive October hike bets and support the dollar, while a softer one could cement a pause.
- Federal Reserve – Will policymakers signal another hike? Comments ahead of the 27–28 October meeting could shift interest-rate expectations and dollar sentiment.
- Brent crude – Could an oil rally fuel dollar volatility? Higher oil prices may intensify inflation concerns and risk aversion, potentially influencing both Fed expectations and demand for the dollar.
The bottom line
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.
