The once-mighty U.S. dollar faced another bout of severe turbulence early Thursday, sending shockwaves that have begun to breach the fortress of the $30 trillion Treasury market. In a week marked by heightened volatility, the greenback’s persistent weakness against major global rivals is no longer contained to currency exchanges; it is now actively eroding the value of U.S. government debt. As the currency hovered near a four-year low on January 29, 2026, the correlation between a falling dollar and rising Treasury yields became uncomfortably clear for investors.
Market participants watched with growing unease as the U.S. Dollar Index (DXY) slipped to the 96 level, a critical technical threshold. The decline, which represents an approximate 11% drop over the past year, has triggered a modest but significant selloff in long-dated government bonds. According to market data, yields on benchmark 10-year and 30-year Treasurys ticked higher by several basis points during morning trading, a classic sign that investors are demanding higher returns to hold assets denominated in a depreciating currency.
This spillover effect marks a dangerous new phase in the current economic cycle. For decades, Treasurys have been the world’s ultimate safe-haven asset. However, the simultaneous slide of both the dollar and bond prices suggests that foreign investors—who are crucial to financing the U.S. debt—are reassessing the real returns of holding American paper. As the currency weakens, the purchasing power of the fixed income generated by these bonds diminishes for overseas holders, prompting them to sell.
Mixed Messages from Washington
The catalyst for Thursday’s intensified volatility appears to be conflicting signals emerging from the highest levels of the U.S. government. According to reports from Dow Jones, a primary driver of the selloff was President Donald Trump’s comments earlier in the week, where he indicated he was "not concerned" about the dollar’s recent slide. This apparent indifference from the Oval Office was interpreted by traders as a green light to continue selling the greenback, exacerbating the currency’s downward momentum.
In an attempt to stem the bleeding, Treasury Secretary Scott Bessent appeared on CNBC to reaffirm the administration’s commitment to a "strong dollar policy." However, the market’s reaction suggested that the President’s casual dismissal carried more weight than the Secretary’s traditional assurances. The disconnect between the President and his Treasury Secretary has injected a layer of policy uncertainty that markets despise, fueling the narrative that the administration may tacitly welcome a weaker dollar to boost exports, regardless of the inflationary consequences.
The Treasury Market Under Pressure
The mechanics of how currency weakness infects the bond market are straightforward but punishing. A weaker dollar signals potential inflationary risks ahead, as the cost of imported goods rises. Inflation is the arch-enemy of fixed-income assets because it erodes the purchasing power of future interest payments. Consequently, bondholders sell their positions, driving prices down and yields up.
Tom di Galoma, a managing director at Mischler Financial Group, highlighted this dynamic, noting that the President’s lack of concern was a key catalyst opening the way for further dollar selling. According to di Galoma, a weaker currency erodes the real returns for foreign investors holding long-term U.S. debt. With the Federal Reserve holding interest rates steady at 3.5%-3.75% during their January 28 meeting, the bond market is left vulnerable to these currency-induced inflationary fears without the immediate promise of further rate cuts to cushion the blow.
Global Ripples and the “Sell America” Trade
The dollar’s stumble has emboldened its primary rivals. The Euro broke above $1.20 for the first time since 2021, while the British pound surged to approximately $1.38. Meanwhile, the Japanese Yen strengthened to around 152 per dollar, fueled by speculation of coordinated intervention. These movements are part of a broader trend that some analysts are calling the "Sell America" trade, where capital rotates out of U.S. assets into commodities and foreign equities.
Nowhere is this flight from the dollar more evident than in the commodities market. Gold prices have skyrocketed, surging past $5,500 an ounce—a near doubling from a year ago. This historic rally in precious metals serves as a barometer for the market’s declining faith in the dollar’s purchasing power. As investors flee dollar-denominated assets, they are seeking refuge in tangible stores of value, further pressuring the U.S. financial system.

Conclusion
The events of January 29, 2026, serve as a stark reminder of the fragile interplay between currency strength and sovereign debt. While a weaker dollar may offer short-term advantages for trade competitiveness, the seepage of this volatility into the $30 trillion Treasury market poses systemic risks. If foreign appetite for U.S. debt wanes just as borrowing needs remain high, the result could be structurally higher borrowing costs for the government and consumers alike. As Washington sends mixed signals and inflation risks resurface, the Treasury market is no longer an isolated sanctuary but a volatile frontier reacting to every tick of the falling dollar.
Frequently Asked Questions
A weak dollar often leads to higher Treasury yields because foreign investors demand better returns to compensate for the depreciating currency. As the value of the dollar drops, the real return on fixed-income assets diminishes for overseas holders, prompting a selloff that drives bond prices down and yields up.
The volatility was primarily triggered by conflicting messages regarding currency policy from the US administration. While the Treasury Secretary advocated for a strong dollar, the President expressed a lack of concern regarding the currency slide, leading investors to sell both dollars and government bonds due to policy uncertainty.
Investors are shifting capital into gold and foreign currencies as part of a strategy described as the Sell America trade. With the dollar hitting multi-year lows and inflation risks rising, market participants are seeking safe havens like precious metals, which reached record highs, to preserve purchasing power against a weakening US financial system.
Inflation is considered the enemy of bonds because it erodes the purchasing power of future interest payments fixed at the time of issuance. When a weak currency signals rising import costs and inflation, bondholders tend to sell their positions, which results in lower bond prices and structurally higher borrowing costs for the government.
Foreign investors are selling US debt because the falling value of the greenback reduces the purchasing power of the fixed income generated by these bonds. As the currency weakens against rivals like the Euro and Yen, holding American paper becomes less attractive, forcing overseas entities to reassess the real returns of their investments.
