US Treasuries Rise as Dollar Swings Shape Euro Returns

The attraction is easy to see. In this rate environment, Treasury prices have been trading below par, which means buyers can lock in higher effective yields than the coupon suggests. The Italian analysis behind this story points to US paper offering more income than comparable BTPs, especially on shorter maturities such as the 2028 area, where the gap is wide enough to matter for long-term allocators. Even a February 2033 T-bond, priced around 91.50 with a 3.50% coupon, can still compete with inflation-linked returns in Europe.

But the dollar is the swing factor. Earlier this year, one dollar cost 1.1721 euros; recently it has been closer to 1.1411. That move has helped euro-based investors holding US assets, but it can just as easily reverse and erase part of the bond income. In other words, the buyer of a Treasury is not just betting on US rates — they are also taking a view on the currency.

That is why the current setup is so interesting. The US economy still shows full employment and inflation around 3.7%, well above the Federal Reserve’s comfort zone, while the public debt burden keeps pushing yields higher over time. At the same time, Treasury markets have been getting support from a risk-off mood as investors seek safety ahead of a 20-year auction and digest softer sentiment around artificial intelligence and a run of economic data. The result is a market where the safest assets are also becoming some of the most compelling income assets.

For bond investors, the practical lesson is simple: duration matters, and so does diversification. Shorter-dated US bonds reduce some of the rate and currency uncertainty, while longer maturities offer more income but more price sensitivity. For euro-based portfolios, a modest allocation to non-euro bonds can make sense, but the Italian guidance here is sensible — keep foreign-currency fixed income to roughly 5% to 10% of the portfolio if risk tolerance is only moderate.

That is also why the exchange-traded funds matter. The TLT long Treasury fund has been volatile, but its price action shows how quickly sentiment can swing when yields drop and haven demand returns. UUP, which tracks a stronger dollar, has also pulled back from recent highs, underscoring how closely bond and currency markets are still linked.

The long-term takeaway for investors is not to chase yield blindly, but to understand what is being paid for. US Treasuries can still be a valuable diversifier, especially when yields are near 5% on some maturities, but for non-dollar investors the currency can make the difference between a good bond investment and a disappointing one. Worth watching, and worth owning only with a clear plan.
