Who Actually Absorbs the Cost of US Deficits?United States 10 Year Government Bonds YieldTVC:US10YNovaque_ResearchThe US Treasury will issue $125 billion in notes and bonds during the week of 9 November. In its 4 November refunding statement, the Treasury explained that approximately $97 billion will refinance privately held securities reaching maturity, leaving around $28 billion of additional cash raised from investors. That distinction is important. The headline issuance amount does not represent an equivalent increase in government borrowing. However, refinancing existing debt still requires investors to accept prevailing market yields, and the price at which that debt clears affects financing conditions across the economy. The Treasury's November statement also indicated that nominal coupon auction sizes are expected to remain broadly unchanged over the next several quarters. Separately, its 2 November borrowing estimates projected $618 billion of privately held net marketable borrowing in the fourth quarter of 2026 and $800 billion in the first quarter of 2027. The United States therefore has substantial ongoing financing requirements, even if next week's refunding is largely a rollover of existing obligations. Our interest is less in the government's immediate ability to issue debt and more in how the financial system absorbs it. Every Treasury security must ultimately be held by an investor, financed through an intermediary or purchased by an institution managing its own balance sheet. The conditions under which those transactions occur influence the marginal cost of capital. The Bond Market Is Currently Absorbing Two Different Risks US two-year yield near 4.51%, the ten-year around 4.86% and the thirty-year around 5.26%. All three have declined from their early-October highs, despite the stronger-than-expected US employment report. The Bureau of Labor Statistics reported that October payrolls increased by 165,000, while unemployment remained at 4.1%. That result strengthened the argument for continued Federal Reserve restriction. Yet MFS Investment Management, in its 6 November weekly market review, observed that the ten-year Treasury yield had fallen from approximately 4.94% the previous Friday to 4.86%, even as technology equities corrected sharply. This distinction matters because Treasury yields contain several different risk components. Shorter maturities are relatively sensitive to expectations for Federal Reserve policy. Longer maturities reflect expected future short-term rates, inflation compensation, term premium and demand for duration. Our interpretation is that markets are simultaneously pricing persistent monetary restriction and the possibility that weaker asset prices will tighten financial conditions independently of central-bank decisions. The latter helps explain why long-term government bonds can rally while investors continue expecting higher policy rates. There is, however, an important limitation to the Treasury-supply thesis: the current decline in yields does not support an argument that investors are already demanding materially higher returns to absorb government debt. The next auctions provide an opportunity to test whether that remains the case. The Marginal Buyer Determines the Price The Treasury's refunding schedule includes $58 billion of three-year notes on Monday, $42 billion of ten-year notes on Tuesday and $25 billion of thirty-year bonds on Thursday. Each maturity attracts investors with different financial objectives. Pension funds and insurers can hold longer-duration securities to match future liabilities. Banks assess government bonds against regulatory capital, liquidity and interest-rate risk requirements. Foreign investors must consider currency exposure and hedging costs. Hedge funds may finance relative-value Treasury positions through repurchase agreements. These distinctions matter because demand is constrained by the balance sheet and investment objectives of the marginal buyer. A pension fund may consider a higher long-term yield attractive because it reduces the present value of liabilities. A leveraged investor may require a greater yield concession if repo financing becomes expensive or market volatility increases. Primary dealers provide another important transmission channel. When auction demand is insufficient to distribute securities immediately, dealers may retain more inventory and finance that inventory through wholesale markets. That can increase the amount of balance-sheet capacity required to intermediate government debt. The potential consequence is a higher price for providing liquidity elsewhere. I would not assume that every additional dollar of Treasury issuance crowds out private borrowing. Government securities also serve as high-quality collateral and can support secured financing. The relevant question is whether intermediation capacity expands sufficiently to accommodate the additional supply without materially raising financing costs. Auction results will provide evidence about that question. A consistently larger auction tail, weaker end-investor demand or increased dealer allocations would deserve attention, particularly if accompanied by deterioration in repo-market conditions. The Treasury General Account Deserves Greater Attention The Treasury's cash balance introduces a second financing channel that investors sometimes overlook. According to the Federal Reserve's H.4.1 balance-sheet release for 5 November, the Treasury General Account averaged approximately $957 billion during the week ending 4 November. Over the same period, reserve balances held at Federal Reserve Banks averaged $2.93 trillion. The Treasury General Account operates as the federal government's deposit account at the Federal Reserve. When taxes or debt-issuance proceeds increase that balance, money generally moves out of the private banking system. Treasury spending reverses the process. Holding other balance-sheet factors constant, a rising Treasury cash balance reduces bank reserves. The latest observations illustrate the mechanism, although they do not establish a one-variable causal relationship. The Federal Reserve reported that the TGA declined by approximately $42.6 billion from the preceding week's average, while bank reserve balances increased by approximately $36.3 billion. Those movements are consistent with an easing of reserve pressure during the reporting period. However, other Federal Reserve liabilities, currency circulation, securities transactions and money-market operations also influence the reserve balance. The observed changes cannot be attributed exclusively to Treasury cash management. Looking ahead, the Treasury stated on 4 November that the TGA could reach approximately $1.025 trillion, subject to a $50 billion range, in late November and again in late January. A rebuilding of government cash balances could therefore absorb additional banking-system liquidity. Whether that becomes restrictive depends on where the funds originate and how other parts of the financial system respond. For example, money-market funds reallocating funds from Federal Reserve reverse-repurchase facilities into Treasury bills can produce a different reserve effect from securities purchased using commercial bank deposits. The composition of financing matters alongside its size. Why the Federal Reserve Balance Sheet Is Only Part of the Story Federal Reserve Economic Data shows total Federal Reserve assets of approximately $6.75 trillion on 4 November. That figure is below the extraordinary levels reached during the pandemic-era expansion of the central-bank balance sheet, but it remains substantially above pre-pandemic levels. The Federal Reserve's latest data also show substantial aggregate bank reserves. These observations weaken the case for describing current conditions as an acute system-wide liquidity shortage. Nevertheless, the existence of ample aggregate liquidity does not guarantee that every institution can access financing on equivalent terms. Liquidity can become concentrated in particular institutions, collateral instruments or market segments. Regulatory constraints, risk limits and dealer balance-sheet capacity influence how readily capital can move between them. This is particularly important during market volatility. The recent technology correction has coincided with wider credit spreads and greater demand for defensive assets. Reuters reported on 6 November that borrowing-risk indicators for some AI-related companies had deteriorated, even though broader Treasury-market liquidity indicators had not reached crisis conditions. We regard that distinction as central to the analysis. The financial system can remain adequately funded in aggregate while individual borrowers experience significantly higher refinancing costs. The Real Economy Absorbs the Cost Through Capital Allocation Treasury yields influence private investment because they form an important component of the benchmark against which investors evaluate risk. The cost of corporate debt incorporates the government yield of a comparable maturity plus compensation for credit and liquidity risks. Equity valuations similarly reflect required returns, although earnings expectations and business risk also matter. When the government borrowing benchmark rises, companies must generate higher prospective returns to justify new investment. Consider the economics of an infrastructure project requiring substantial upfront capital. Management must assess construction costs, financing requirements, expected utilization, operating margins and the period over which the investment will recover its initial expenditure. An increase in financing costs can make a marginal project unattractive even when expected revenue remains positive. This is relevant to the AI infrastructure cycle. Reuters has reported concerns about the financing intensity of data-centre expansion, while MFS has connected the recent equity correction to uncertainty over how political developments could affect AI-related investment. Our interpretation is that the market is beginning to examine whether projected returns on AI capital expenditure are sufficient to compensate investors for the risks involved. The distinction becomes particularly consequential in private markets. A listed company is continuously repriced by investors. A privately held company can maintain its reported valuation for longer, but an unchanged valuation does not prevent its next funding round from becoming more expensive. For venture-backed businesses, the effect appears through dilution, more demanding investment milestones, shorter financing runways and pressure to demonstrate stronger unit economics. For mature companies, it can appear through higher debt-service costs or the postponement of capital projects. The broader economic consequences depend on whether those financing constraints become sufficiently widespread to reduce investment and employment. The Counterargument: Treasury Supply May Be Easier to Absorb Than Expected The strongest challenge to my interpretation is that the Treasury market continues to benefit from substantial structural demand. Government bonds remain central to global reserve management, pension investment, collateral markets and institutional liquidity portfolios. Higher yields can also attract additional long-term buyers, improving the market's capacity to absorb supply. The recent rally in longer-duration Treasuries is consistent with that argument. The Treasury has also retained flexibility over its issuance profile and buyback programme. Its November refunding statement anticipates up to $70 billion of off-the-run securities buybacks for liquidity support during the coming quarter, alongside a separate allowance for short-maturity cash-management buybacks. Those operations do not eliminate federal borrowing requirements, but they can improve the functioning of particular market segments. Our thesis would weaken if the refunding auctions demonstrate strong investor demand, bank reserves remain ample, repo conditions stay orderly and corporate credit spreads stabilize. That outcome would suggest that government financing requirements are being accommodated without an additional, material tightening of private capital conditions. It is entirely plausible. What We Would Watch Next The immediate evidence will come from the three-, ten- and thirty-year Treasury auctions. We would examine auction tails, bid-to-cover ratios, bidder allocations and subsequent secondary-market performance to assess whether the supply requires an unusual yield concession. The second test is the evolution of Treasury cash balances relative to bank reserves and secured funding conditions. A rising TGA becomes more concerning when it coincides with persistent pressure in repo markets or reduced reserve availability. The third is corporate credit. If technology equities remain weak but borrowing spreads stabilize, the correction is more likely to remain concentrated in valuations and positioning. Continued credit deterioration would create a stronger case for financial stress transmitting into real investment decisions. What I think is being tested is the private sector's willingness to absorb government duration at prices that still permit productive investment elsewhere. The Treasury's financing programme does not automatically imply a liquidity shortage. The current yield structure offers little evidence of such a shortage. But government financing has consequences beyond the fiscal accounts. When the marginal price of safe assets changes, it influences the return investors demand from businesses, infrastructure and financial assets. The important question for capital markets is therefore whether the financial system can continue intermediating Treasury supply without forcing a broader repricing of private capital. That question deserves attention even when the Federal Reserve makes no change to its policy rate.
