Treasury Secretary Scott Bessent told Congress and CNBC this month that the department’s enlarged buyback of more than $5 billion in 10- and 20-year notes was a “success.” Yields on those maturities nonetheless sit at multi-decade highs, with the benchmark 10-year trading above 5% after the Iran war added roughly 100 basis points to long rates since February. Liquidity operations are not a substitute for monetary policy—and they are certainly not an affordability strategy for mortgage holders paying more than 7%.
Buybacks fix plumbing, not inflation expectations
The Treasury expanded repurchases in September to as much as $6 billion per operation—triple the usual size—targeting the less liquid long end where pension funds and insurers trade off-the-run securities. That can narrow bid-ask spreads and help dealers warehouse inventory during stress. It does not change the fundamental supply of U.S. debt, the Federal Reserve’s policy rate, or investors’ belief that inflation risk remains elevated while oil and shipping costs swing with Hormuz.
Bessent’s counterfactual—that yields might have climbed even higher without the buyback—is impossible to prove and easy to invoke. What is measurable is that auctions following the operation still priced long debt at eye-watering levels, and that mortgage rates tracked those yields upward. Households do not experience “successful” buybacks; they experience monthly payments.
Only the Fed sets the short rate; markets set the rest
The Federal Reserve held its target range at 3.75% to 4% after its September meeting, signaling it will move slowly while war-driven energy shocks complicate the inflation picture. Long yields embed expectations of that path plus term premium for holding duration when deficits remain large. Treasury cannot decree that premium away by repurchasing a few billion dollars of outstanding notes in a $28 trillion market.
Politicians who want lower rates should focus on what actually moves them: credible fiscal plans, stable inflation, and a Fed that can cut when data allow—not on treating the Treasury’s trading desk as a shadow central bank. Using buybacks to signal concern about borrowing costs risks moral hazard: investors may assume Washington will always intervene, which can distort positioning without delivering sustained relief.
What policymakers should do instead
Keep buybacks within their stated purpose—market functioning—with transparent schedules at quarterly refundings, including the Nov. 4 update Bessent has promised. Do not oversell them on morning television as proof that America has the “best-performing bond market in the developed world” while families refinance at generational highs.
Pair any liquidity program with honest messaging about war premiums in energy markets and the time it takes for rate cuts to reach credit cards and home loans. If the administration wants affordability, it needs a coordinated macro story: energy diplomacy that stabilizes crude, fiscal discipline that does not crowd out private investment, and a Fed that can ease when inflation truly cools—not a larger repurchase ticket that treats symptoms on the long end while the disease is expectations.
We supported Treasury’s right to conduct technical buybacks when markets seized in past crises. This autumn’s episode is different: yields rose into the operation and stayed there. Calling that victory insults voters who can read their mortgage statements. Court process for press credentials matters for democracy; credible rate paths matter for their wallets. Washington should not confuse the two kinds of intervention.
