The bid is gone
The Federal Reserve is no longer the buyer of last resort. It is a seller. This fundamental shift in the mechanics of the bond market is creating a vacuum that the private sector is struggling to fill. As the central bank aggressively reduces its balance sheet, the primary dealer system is choking on an overflow of government paper. The safety net has been shredded. What remains is a raw, unshielded market where price discovery is becoming increasingly painful for the U.S. Treasury.
Quantitative Tightening (QT) is the silent killer of market liquidity. By allowing Treasuries to roll off its balance sheet without reinvestment, the Fed is effectively forcing the Treasury Department to find new lenders. According to recent data from Reuters, the 10-year Treasury yield has spiked to levels not seen since the height of the 2023 volatility, hovering near 4.85 percent as of February 19. This is not a coincidence. It is the direct result of a supply-demand imbalance that the Fed is intentionally exacerbating.
The mechanics of the balance sheet drain
The Fed’s largest holding is government debt. When the Fed wants to hold fewer bonds, it must sell them or let them mature without replacement. This increases the supply of bonds in the open market. When supply increases and demand remains stagnant, bond prices fall. Because bond prices and yields move in opposite directions, yields skyrocket. This makes it significantly more expensive for the federal government to borrow money to fund its operations.
The technical term for this pressure is the term premium. For years, the Fed’s presence in the market suppressed this premium, effectively subsidizing the government’s deficit spending. Now, that subsidy is being withdrawn. Investors are demanding higher yields to compensate for the risk of holding long-term debt in an environment where the largest price-insensitive buyer has left the room. The cost of servicing the national debt is now on a trajectory to eclipse defense spending, a fiscal reality that the Bloomberg terminal monitors with increasing alarm.

Fed Balance Sheet vs. 10-Year Treasury Yield (Last 12 Months)
The Treasury General Account and the Reverse Repo Facility
The plumbing of the financial system is leaking. For much of the past year, the Treasury was able to mitigate the impact of QT by draining the Reverse Repo (RRP) facility. This acted as a massive reservoir of liquidity, absorbing the excess supply of Treasury bills. However, that reservoir is now effectively dry. As the RRP balance approaches zero, the burden of financing the deficit shifts entirely to bank reserves.
Bank reserves are the lifeblood of the interbank lending market. When these reserves drop below a certain threshold, the system becomes fragile. We saw this in September 2019, and the current trajectory suggests a repeat performance. The Treasury is now forced to issue more long-dated coupons to refill the Treasury General Account (TGA), just as the Fed is accelerating its exit. This pincer movement is trapping the Treasury between a need for cash and a market that is increasingly unwilling to provide it at affordable rates.
Foreign appetite is waning
The domestic struggle is compounded by international apathy. Historically, foreign central banks were the primary absorbers of U.S. debt. That is no longer the case. Geopolitical shifts and the weaponization of the dollar have led major holders like China to diversify away from Treasuries. Japan, dealing with its own currency interventions and yield curve shifts, has become a less reliable buyer. Without foreign demand to offset the Fed’s selling, the marginal buyer is now the price-sensitive domestic hedge fund.
Hedge funds do not buy for safety; they buy for carry. They require a significant yield premium to take on the duration risk of a 10-year or 30-year bond. This transition from institutional “buy and hold” players to speculative “carry trade” participants introduces massive volatility. Any sign of a failed Treasury auction, such as the weak 20-year bond auction observed on February 18, sends shockwaves through the entire financial system. The primary dealers, required by law to bid at these auctions, are finding their balance sheets bloated with inventory they cannot flip.
The cost of the deficit
Washington is ignoring the math. The Congressional Budget Office (CBO) has repeatedly warned about the long-term sustainability of the current fiscal path, but the warnings fall on deaf ears in an election cycle. The reality is that the Fed cannot bail out the Treasury forever without reigniting inflation. If the Fed pivots to buying bonds again to save the Treasury, the dollar will likely face a crisis of confidence. This is the ultimate catch-22 of modern monetary policy.
The Treasury’s borrowing needs are projected to remain at record highs for the foreseeable future. With the Fed committed to its balance sheet reduction program, the friction between fiscal and monetary policy is reaching a breaking point. Every basis point increase in the 10-year yield adds billions to the annual deficit, creating a feedback loop that is difficult to break. The market is now pricing in a “higher for longer” regime not just for interest rates, but for the risk premium associated with U.S. sovereign debt.
The next critical data point to watch is the February 25 Treasury auction of 2-year and 5-year notes. If the bid-to-cover ratio continues to deteriorate, it will signal that the private market’s capacity to absorb the Fed’s discarded debt has reached its limit. Watch the 4.92 percent level on the 10-year yield; a break above this could trigger a disorderly liquidation of long-duration assets across the board.
