Hedge Funds Rebuild Dollar Longs as Energy Positions Sharply Cut
nashnova research
In the week to September 22, speculative funds rapidly rebuilt dollar longs — the DXY rose ~1%, ending a seven-week slide — while energy positions were sharply cut and copper stood out as the sole commodity gaining fresh bets.
Why did dollar bulls come back so fast?
The Fed's latest 25-basis-point hike widened the dollar's yield advantage, and markets began pricing in further tightening.
This means → holding dollars now pays more interest than virtually any major alternative, pulling capital back.
The dollar index (DXY) rose roughly 1% in a single week, snapping a seven-week losing streak.
Why did the yen take the hardest hit?
The Bank of Japan raised its benchmark rate to 1.25%, but rising U.S. Treasury yields more than offset the move.
Yen positioning saw the week's largest swing toward short bets.
In plain terms = Japan hiked, but U.S. rates are higher and climbing faster — the yen still can't compete for yield.
Why did energy lead the selloff?
WTI crude fell roughly 10% and diesel dropped about 9%; the Bloomberg Commodity Index lost 1.8% on the week.
Key drivers: improved oil flows through the Strait of Hormuz — the chokepoint linking the Persian Gulf to open water — and the restart of Saudi Arabia's East-West pipeline, both easing the geopolitical risk premium.
This means → the "supply-disruption fear" that had propped up prices is fading, and crude is reverting toward fundamentals.
Why did copper rally against the tide?
Industrial metals were the only sector to attract net new longs; copper (HG1) rebounded roughly 6% in one week.
Saxo Bank attributed this to persistently tight supply outside the U.S. and extremely low exchange inventories in China.
In plain terms = the world was dumping commodities, but there simply isn't enough physical copper — so buyers piled in.
Silver and platinum also posted gains despite headwinds from rising Treasury yields and a stronger dollar.
Did agricultural commodities escape the rout?
Agriculture weakened across the board, with soybean oil, cocoa, and coffee leading losses.
Managed-money funds — professional speculative positions — turned net sellers in every sector except industrial metals.
Brent crude net shorts rose by 64,500 contracts, gold net shorts by 5,700, and soybean oil and cotton were also visibly cut.
Where do energy positions go from here?
Brent crude surged more than 3% on Monday, pushing futures back above $107 a barrel.
The trigger: President Trump refused to reach a ceasefire agreement with Iran, snapping the geopolitical risk premium back into the price.
This reflects the core tension in energy markets — improving supply pulls prices down, but a single geopolitical flashpoint can restore the premium overnight. The next move in positioning remains highly uncertain.
