US Treasury Bond Buybacks Weaken Dollar, Boost EUR/USD to Best Level Since June

EUR/USD rallied sharply this week, reaching 1.1681 on August 20, 2026 — its strongest level since June — propelled by a surprising shift in US Treasury policy that sent the dollar tumbling. The catalyst was the US Treasury’s announcement on August 19 to expand bond buyback operations targeting longer-dated debt, a move aimed at curbing soaring long-term yields that had unsettled markets. This intervention eased the 30-year Treasury yield from a 19-year high of 5.337% down to 5.184%, injecting fresh liquidity and undermining the dollar’s appeal despite a hawkish Federal Reserve tone.

Dollar Retreat Defies Fed Hawkishness

The US Dollar Index (DXY) fell to an eleven-week low near 98.90 on August 20, extending losses that began ahead of the release of the Federal Open Market Committee (FOMC) minutes from the July 28-29 meeting. Those minutes revealed that “many participants” remained open to further rate hikes if inflation failed to ease, and three regional Fed presidents had dissented in favor of an immediate 25 basis point increase. Yet, markets interpreted the Treasury’s bond buyback as a signal that the US government prioritized stabilizing long-term yields over maintaining dollar strength. This “debasement trade” released dollar liquidity and pressured the currency, even as the Fed’s hawkish stance suggested tighter policy ahead.

MUFG strategists now expect the Fed to hold rates steady through the remainder of 2026, with easing pushed back to early 2027. This recalibration of Fed expectations, combined with the Treasury’s actions, has created a complex backdrop where dollar weakness coexists with the possibility of future tightening.

Eurozone Economic Data Bolsters the Euro

On the other side of the Atlantic, the euro benefited from encouraging economic indicators. The Euro Area Composite Purchasing Managers’ Index (PMI) for July rose to 51.9 from 50.0 in June, signaling expanding business activity at the fastest pace in months. Germany’s ZEW Economic Sentiment index for August also exceeded forecasts, climbing to 34.2. These data points suggest resilience in the Eurozone economy despite ongoing geopolitical tensions and inflationary pressures.

The European Central Bank (ECB) had already responded to inflation concerns with a 25 basis point rate hike on June 11, 2026. ECB policymaker Olli Rehn noted on August 19 that wage growth remained moderate and there were no clear signs of second-round inflation effects. Markets are now pricing in a 90-94% probability of another 25 basis point hike at the ECB’s upcoming rate decision on September 9, 2026. This expectation supports the euro’s recent gains and underpins EUR/USD’s rally.

Risk Sentiment and Market Dynamics

The Treasury’s bond buyback announcement was also viewed as a move to soothe jitters in the bond market, lifting overall risk sentiment. This helped risk-sensitive currencies like the Australian dollar and British pound, which also advanced against the dollar this week. The USDCAD pair, for example, fell by 0.73%, reflecting a broader dollar retreat.

However, despite the euro’s rise, EUR/USD remains close to its opening level for 2026. This suggests that, after eight months of policy repricing—including the ECB’s rate hike, ongoing US labor market strength, and the dollar’s eleven-week low—the pair is still range-bound. Technical analysis points to overbought momentum in EUR/USD, raising the risk of a near-term pullback.

What Traders Should Watch Next

Looking ahead, the market’s focus will be on several key events that could reshape the EUR/USD trajectory. The ECB’s rate decision on September 9 is paramount, with a widely expected 25 basis point hike. Confirmation of this move could reinforce euro strength, while any dovish surprises might trigger a reversal.

On the US side, a cluster of important economic data is due on August 26, including the Core PCE Price Index (a key inflation gauge), preliminary GDP growth figures, durable goods orders, personal income, and personal spending. These releases will provide fresh insight into the US economy’s health and inflation trajectory, influencing Fed policy expectations and, by extension, the dollar.

The Jackson Hole Symposium and the August Nonfarm Payrolls (NFP) and Consumer Price Index (CPI) data will also be critical in shaping market sentiment and Fed outlook.

Final Verdict

This week’s EUR/USD rally underscores how US Treasury policy can override even hawkish Fed signals in the short term, pushing the dollar lower and lifting the euro. However, the pair’s proximity to its year-open level and technical overbought conditions suggest caution. The upcoming ECB rate decision and US economic data releases will be key to determining whether this rally can sustain or if a retracement is imminent.

FAQ

Q1: Why did EUR/USD rise despite the Fed’s hawkish minutes? The US Treasury’s surprise bond buyback program lowered long-term yields and injected liquidity, weakening the dollar even as the Fed signaled readiness to hike rates if inflation persists.

Q3: What risks could reverse the EUR/USD rally? Overbought technical momentum and a potential hawkish surprise from the Fed or dovish ECB signals could trigger a pullback.

Q4: What should traders watch next week? The ECB’s September 9 rate decision and US data on August 26—including Core PCE, GDP, and spending—will be critical for EUR/USD direction.
