The Treasury's move to double buyback operations for longer-dated notes drove yields lower and the dollar to new lows. Euro rose above $1.17, its highest since May.
The US Treasury announced it will at least double the size of liquidity support buyback operations for longer-dated nominal coupon securities, starting September 9. The current quarterly maximum is $16 billion. The move changed the tone across capital markets, driving long-term yields lower and fueling a broad equity recovery. The greenback slumped against nearly every major and emerging-market currency.
Traders said the signal effect outweighed the actual size relative to daily Treasury turnover. The announcement pushed the 10-year yield down about six basis points within minutes, and the 30-year yield followed. By the close, the 10-year yield stood at 4.67%, down sharply from levels seen earlier in the week.
The euro jumped 0.90% against the dollar on the session, its best day since late March. It settled near $1.1680 and extended gains above $1.17 in Asian trading for the first time since mid-May. The $1.17 area marks the halfway point of this year's range. The next retracement, the 61.8% level, sits just below $1.18, which also corresponds to the May highs. EUR/USD profile
Dollar-yen reacted in lockstep with the drop in US yields. The pair fell from around ¥159 before the announcement to almost ¥158, a seven-day low. That low matched the 38.2% retracement of the greenback's recovery from the intervention-inspired low on August 3 near ¥155.25. Options for $1.3 billion expire at ¥158 today. The dollar recovered to almost ¥158.75, where sellers emerged, before drifting back to ¥158.20 in the European morning.
Sterling surged to $1.3630, its best level since May 11, surpassing the 61.8% retracement of the decline from the January high near $1.3870. It approached the May highs around $1.3650-60 today, reaching almost $1.3650 where options for about GBP360 million expire.
The Canadian dollar gained on the three-day extension of US tariff threats and the broad dollar sell-off. The greenback fell from around CAD1.3880 to almost CAD1.38 after the Treasury announcement, then dropped further to CAD1.3760 in Asian trading, a new three-month low. Support is seen near CAD1.3700.
The Australian dollar underperformed before the announcement but recovered smartly to test Monday's two-month high near $0.7130, posting an outside up day. It has hardly traded higher today, but the market does not appear done. The next technical target is the $0.7175-$0.7200 area.
Among emerging currencies, the Mexican peso reached its best level since the run-up to the 2024 presidential election, with the dollar falling to about MXN16.9425. The Colombian peso led regional gains with a 1.3% advance to its strongest since October 2018, though the government declared an economic emergency late yesterday, adding spending pressures.
The dollar slumped against the offshore yuan to CNH6.7280, its weakest since February 2023, and approached CNH6.72 today. The PBOC set the fixing at CNY6.7808, a new multiyear low. Against the Indian rupee, the dollar gapped lower initially to a three-day low near INR95.5675 but closed the gap and settled near session highs around INR95.7175, as hawkish Riksbank minutes failed to sustain rupee gains.
Gold jumped almost $188, or 4.3%, to above $4,523, its best level in two months. It settled above its 200-day moving average for the first time since June 4.

West Texas Intermediate crude posted an outside day, reaching almost $85.85 on the session and $86.85 today, near last month's high just above $88. The rally extended for a fifth consecutive session, with October WTI up more than 2.5% near $86.60, the highest in a month.
Asia Pacific equities snapped a two-day slide, led by South Korea's 5.9% rally. Most large bourses were higher except Singapore and New Zealand. European indices struggled to sustain gains, with the Stoxx 600 threatening a seventh consecutive daily decline. US index futures were little changed.
The dollar's weakness was broad-based. Only the Japanese yen and Swedish krona among G10 currencies failed to gain against the greenback today. The Riksbank held its policy rate at 1.75% with a hawkish bias, but the swap market pared expectations for more than one hike.
