U.S. Dollar Gains 3% in H1 to Lead Major Currencies; CFTC Net Longs Hit $37B at Record Accumulation Pace
N.R. Finch
The dollar rallied 3% in the first half of 2026 — reversing last year's 10%-plus slide — while CFTC speculative net longs grew by $37 billion in six months, the fastest build since records began in 2012, driven by Fed rate-hike expectations, AI capital inflows, and U.S. economic outperformance.
It was plunging six months ago — what flipped?
Last H1 the dollar fell over 10%, the worst first-half drop since the early 1970s. This H1 it gained 3% — a worst-to-best reversal in twelve months.
This means → no single catalyst; three forces flipped simultaneously: persistent U.S. economic outperformance, an AI boom pulling capital home, and new Fed Chair Kevin Warsh anchoring policy to inflation.
In plain terms = last year markets bet the U.S. would ease; this year they discovered it might tighten further — money followed.
How many hikes is the Fed pricing in?
Warsh has made inflation his explicit priority; current inflation remains well above the 2% target.
Markets now price at least one hike this year, with roughly 50% odds of a second — just weeks ago the consensus was no move at all.
This means → the speed of the expectation shift itself is boosting the dollar, even before any hike lands.
How fast are speculators piling in?
CFTC data: speculative dollar net longs sit at roughly $30 billion, the highest since Trump's second term began.
The pace matters more: a net increase of about $37 billion in H1 — the fastest six-month build since CFTC records began in 2012.
Neuberger portfolio manager Joseph Purtell: "Rising U.S. real rates will push the dollar stronger still — a break above the past six-to-nine-month range is the more likely outcome."
How is the AI boom pulling money into the U.S.?
Bank of America estimates roughly $341 billion flowed into U.S. equities year-to-date, versus $134 billion in the same period last year — more than 2.5× the pace.
Sources: AI infrastructure buildout, trillion-dollar-class IPOs such as SpaceX, and the rise of quantum-computing firms — all concentrating global capital in the U.S.
Natixis global market strategy head Mabrouk Chetouane: "If tomorrow's growth depends on compute, energy, and labor — which country benefits most? America. Winner takes all."
This reflects a dollar story that goes beyond rates: it is an "industrial magnet" story — whoever owns the next growth engine absorbs global savings.
Who is paying the price of a strong dollar?
Dollar-yen has hit a 40-year high, alarming Japanese officials. Euro-dollar is near its year-to-date low; Morgan Stanley warns of near-term risk to 1.10 (currently ~1.135).
The Korean won has fallen to a record low, inflating equity-bubble risk. India and other emerging markets are burning reserves or hiking rates to offset dollar pressure.
In plain terms = every tick higher in the dollar raises import costs from Auckland to Zurich — central banks globally are absorbing the pressure passively.
Can the rally last into H2?
Eurizon SLJ CEO Stephen Jen: "Nobody welcomes a strong dollar — including America itself." Yet he concedes the appeal of U.S. firms and onshore investment is "simply too strong."
Purtell flags the longer-term risk: structural concerns around U.S. fiscal sustainability will still weigh on the dollar eventually.
This means → the second half hinges on two variables: whether the Fed actually delivers a hike, and whether AI capital inflows keep materializing — if either breaks, the reversal could be equally swift.
