Citadel Securities warns Treasury bond buybacks risk inflation and dollar weakness

Citadel Securities, one of the largest market-making firms on the planet, just lobbed a grenade at the Treasury Department’s playbook. In a client note authored by Nohshad Shah, the firm labeled the government’s expanded bond buyback program a form of “financial repression,” warning it could weaken the dollar and fan inflationary pressures at exactly the wrong time.

The critique lands as Treasury Secretary Scott Bessent doubles down on a strategy that looks increasingly like a high-wire act: buying back long-dated bonds to suppress yields while funding those purchases with short-term debt.

What the Treasury is actually doing

The Treasury doubled the cap on liquidity-support buybacks for 10- to 30-year securities from $2 billion to at least $4 billion per operation, a policy running through November 4. That change could allow for roughly $14 billion in additional buyback volume.

The strategy resembles what bond market veterans call an “Operation Twist,” a technique the Federal Reserve deployed in 2011 to push down long-term rates by selling short-term securities and buying longer-dated ones. Except this time it’s the Treasury running the show, not the Fed.

Citadel’s note describes the program as “liquidity-neutral and duration-reducing.” Translation: the government isn’t creating new money or reducing its total debt. It’s simply swapping longer-term obligations for shorter ones, which compresses yields on the long end of the curve.

There’s a reason the Treasury felt compelled to act. The 30-year bond yield recently climbed near 5.3%, a level not seen since 2007.

The dollar takes the hit

Following the buyback announcement, the dollar weakened by nearly 0.8%, a significant single-day move for the world’s reserve currency. Gold prices surged in tandem, the classic flight-to-safety trade that investors deploy when they smell currency debasement.

When the Treasury artificially suppresses long-term yields, it reduces the attractiveness of holding dollar-denominated bonds for foreign investors. Capital flows elsewhere, the dollar weakens, and imported goods get more expensive for American consumers.

Financial repression by another name

The term “financial repression” carries a specific meaning in economics. It describes government policies that channel funds to the sovereign at below-market rates, effectively forcing savers and investors to subsidize government borrowing. It was the strategy many countries used to work down debt-to-GDP ratios after World War II, keeping interest rates artificially low while inflation gradually eroded the real value of outstanding debt.

Citadel’s use of this language is deliberate and pointed. The firm is essentially arguing that the Treasury’s buyback expansion serves a similar function: keeping long-term borrowing costs artificially suppressed while the real adjustment happens through a cheaper dollar and higher prices. Citadel’s analysis suggests the buyback program papers over fiscal deficits driven in part by substantial spending on AI-related initiatives and a labor market that hasn’t generated enough tax revenue to close the gap.
