US Dollar Index: Rates support further gains – Societe Generale

FXStreet Insights Team FXStreet

Societe Generale’s Kit Juckes links the Dollar’s trajectory to shifting interest rate and growth differentials, noting that US 2-year Treasury yields have surged since the war with Iran while the Dollar Index has only modestly advanced. He argues the Dollar still has room to rally, with the bank’s end-2026 DXY forecast above Bloomberg consensus.

US yields outpace peers, backing Dollar

"Still, the chart below of the Dollar Index and 2-year Note yields, does tell an interesting story. The dollar was already rallying before the Presidential election and continued to do so until January 2025."

"From September 2025 until the outbreak of the war with Iran, 2-year Treasury yields stayed low, in a 3.4-3.7% range despite strong economic growth, an investment boom and signs of inflationary pressures at the margin. Over the same period, the Dollar Index meandered around in a 96-101 range, with EUR/USD trading between 1.14 and 1.21."

"The war changed the interest rate outlook, with 2-year yields rising by over 6% since it started. The dollar has rallied, but only modestly compared to the rate moves we are seeing."

"Even so, the trend (US 2-year yields rising faster than we are seeing elsewhere) is clear enough."

"The day between a Europe-wide holiday and the weekend isn’t a good time to make bold predictions about what will happen next, but the dollar has room to rally from here."

USD/JPY clings to gains around 158.00 after data showed on Friday that Japan's Household Spending fell for the ninth straight month, undermining the Japanese Yen.

Gold remains range-bound below $4,200

Gold has given up some ground after an initial bullish attempt to reach weekly highs, returning to below the $4,200 mark per troy ounce on Friday. The US Dollar’s strong upside momentum, combined with rising US Treasury yields across the curve, seems to keep further gains in the yellow metal under scrutiny.

Has Bitcoin really escaped the macro forces it was built to fight?

Over 17 years ago, Satoshi Nakamoto designed Bitcoin (BTC) on the back of a global financial crisis as an alternative to the global monetary system outside the control of central banks, governments and traditional intermediaries. This raises a key question: has Bitcoin really become independent of the macroeconomic forces it was built to challenge?

The Euro is not the sick man of Europe. France's bond market is

EUR/USD remains under pressure, near the 17-month low of 1.1161 reached on Monday. The pair has lost more than 7% since its yearly peak, as concerns over France's public finances increasingly weigh on the single currency. But behind the weakness of the Euro (EUR), the problem does not necessarily lie with the European economy as a whole.
