Treasury Secretary Scott Bessent's aggressive intervention to curb rising US borrowing costs has led many investors to believe the dollar will bear the brunt of the policy. The Treasury announced it would at least double planned purchases of outstanding 10- to 30-year bonds after borrowing costs surged to multi-year highs, marking a significant departure from the department's usual "regular and predictable" approach to debt management. This move is interpreted by some as Washington taking a more active role in managing its borrowing expenses, reigniting concerns that such policies could undermine confidence in the dollar and encourage investors to seek alternative assets.

Market participants, including Gerald Gan, CIO of Reed Capital, explicitly state that "the dollar certainly is the biggest casualty." He believes Bessent is intentionally pushing down long-term real rates and signaling tolerance for a weaker dollar to support the economy. Andrew Canobi of Franklin Templeton echoed this, stating Bessent is "effectively saying we're prepared to sacrifice a bit of dollar strength in order to keep term yields somewhat in check." A Bloomberg gauge of the greenback fell to a three-month low after the announcement, with the yen, Swiss franc, and New Zealand dollar being among the biggest gainers against the US currency.

Audrey Childe-Freeman, Chief FX Strategist at Bloomberg Intelligence, also views the move as potentially bearish for the dollar, suggesting traders might see it as an attempt to suppress market pricing around US fiscal sustainability. Evercore ISI strategists, including Marco Casiraghi, indicated that Bessent would likely welcome these foreign exchange movements, aligning with previous administrations' views on the benefits of a weaker dollar for US competitiveness. Shoki Omori, Deutsche Bank AG's Chief Fixed Income Strategist for Japan, expects the yen to be the primary beneficiary over the next three to six months, also favoring gold, the Swiss franc, and the euro as dollar alternatives. He noted that the price action, with short-term bonds selling off and the dollar falling, suggests investors are questioning the broader US policy mix beyond just interest-rate differentials.
