The New Shape of Risk: Treasury Yields, a $36 Trillion Debt Load, and How Trade Policy Could Tilt the Curve

The Treasury curve suggests a transition rather than a tidy reversion to pre‑pandemic norms. As of August 7, 2025, benchmark yields were roughly 4.32% (3M), 3.92% (1Y), 3.72% (2Y), 3.79% (5Y), 4.23% (10Y), and 4.81% (30Y), according to U.S. Treasury data. That structure—front‑end bills still slightly above the 10‑year while the 2s–10s spread has turned positive—communicates two messages. First, policy remains restrictive relative to longer‑run equilibrium, even after meaningful easing from 2024’s peaks. Second, the long end is holding a discernible term premium relative to the 2‑ to 5‑year sector, likely reflecting persistent deficit financing needs and uncertainty around inflation’s landing zone.

Recent FRED data corroborate the policy shift: the effective federal funds rate averaged about 5.33% from mid‑2024 and has been around 4.33% each month in 2025 through July, implying a full percentage point of easing over the past year. Meanwhile, 10‑year yields have moved down from the 4.8–5.0% zone common in late 2024 to roughly 4.2%–4.4% in recent days. The unemployment rate, at 4.2% in July 2025, suggests labor market cooling but not collapse. Put together, available data suggest investors are embracing a “soft‑ish landing” narrative: growth is moderating from above‑trend, inflation is receding toward target, and the policy rate is drifting lower, albeit gradually.

However, the curve’s kink at the very front end—where the 3‑month bill still yields more than the 10‑year by roughly 9 basis points—signals lingering caution about near‑term growth or policy risk. Historically, deep and persistent curve inversions have foreshadowed recessions; by contrast, today’s partial de‑inversion argues the worst of the leading signal may be behind us. Yet the long end’s resilience above 4% implies that investors demand compensation for two unresolved risks: the fiscal trajectory, and a non‑trivial probability that inflation proves a bit stickier than target. As of August 6, 2025, FRED shows the 10‑year constant maturity yield near 4.22%—fresh enough to guide positioning but still subject to weekly data noise and revisions.

At the sovereign level, financing mechanics are feeling less theoretical and more immediate. Total public debt was about $36.2 trillion as of January 1, 2025, according to FRED’s Federal Debt series, while nominal GDP stood near $30.33 trillion (annualized) in the second quarter of 2025. That implies a debt‑to‑GDP ratio around 119% on a rough, cross‑frequency basis—an approximation rather than a strict accounting ratio, but directionally useful. Even if inflation gradually glides toward the Federal Reserve’s 2% target, rolling maturing debt into coupons in the 3.5%–5.0% range will likely keep interest expense elevated.

The impact depends critically on the Treasury’s issuance mix, the weighted average maturity (WAM) of outstanding debt, and the path of short‑term rates. While WAM and auction schedules are beyond the scope of the data referenced here, the shape of today’s curve itself is instructive. In the 2‑ to 5‑year sector—where a significant share of the coupon stack resides—yields around 3.7%–3.8% are materially below 2024 peaks yet still above the pre‑pandemic era. Longer tenors, around 4.2%–4.8%, embed a modest term premium that has proven sticky. That persistence suggests investors are demanding compensation for the uncertainty around inflation persistence, structural deficits, and the potential for larger term supply.

The macro context matters. With unemployment at 4.2% in July, growth still positive, and the effective policy rate near 4.33% as of July (per FRED), the U.S. does not present as a classic fiscal stress case. But the arithmetic is unforgiving: if nominal growth slows while average interest costs remain near current coupon levels, debt service will take a larger slice of federal outlays. For asset allocators, that raises the question: does the term premium rise further if deficits fail to narrow, or does policy accommodation and stable inflation slowly grind it down? The answer hinges on supply‑demand balance across the curve—particularly the appetite of domestic institutions and foreign reserve managers for longer‑dated paper at yields just north of 4%.

The debt ceiling, while arcane, can be market‑moving when brinkmanship escalates. As the Council on Foreign Relations (CFR) has detailed, the limit—suspended in June 2023 until January 2025—caps Treasury’s borrowing authority rather than authorizing new spending. Since 1960, Congress has raised or suspended the ceiling 78 times, a statistic that shows a long‑standing, if grudging, bipartisan pattern of resolution. CFR notes that repeated showdowns risk missed payments and financial disruption, even if outright default has been avoided historically.

In August 2025, the status of the ceiling beyond January’s suspension is central but not explicit in the datasets referenced here. What is observable is that markets are not currently pricing acute near‑term default risk: bill yields around the front end are elevated for policy reasons, not because of idiosyncratic spikes around presumed X‑dates. Yet investors remember 2011 and 2013, when brinkmanship pushed up short‑dated yields and risk premiums. The takeaway is less about predicting legislative outcomes and more about appreciating that each episode can briefly distort the bill curve, stress money market funds, and complicate Treasury’s cash management—especially when balances at the Treasury General Account become part of the tactical calculus.

From a strategic perspective, the debt ceiling’s main market significance lies in its ability to inject volatility into the shortest maturities and, by extension, ripple into repo markets and risk management frameworks. For the long end, the principal channel is more diffuse: if repeated standoffs signal governance risk or raise the perceived likelihood of fiscal slippage, investors may demand a higher term premium over time. That is not a mechanical relationship, but it is a directional one that helps explain why the 10‑ to 30‑year segment has remained stubbornly above 4% even as the effective policy rate eased through 2025, according to FRED and Treasury data.

UBS frames the latest tariff threats as a negotiating gambit likely to settle at an effective U.S. tariff rate near 15%, an outcome they argue would nudge inflation higher without derailing growth or the equity rally. Their analysts also emphasize that markets are reacting less to trade headlines than in prior cycles, with investors focused on earnings and macro data alongside anticipated Fed easing. UBS further notes that tariffs are increasingly used for geopolitical aims, including pressure campaigns around energy supplies, and that the burden is uneven across trading partners and sectors—Swiss pharmaceutical exporters, for instance, could face particularly high levies in some proposals.

For rates markets, the key question is whether tariffs merely create a one‑off price level adjustment or materially alter the inflation trend. The former might prompt a modest, temporary backup in breakevens and nominal yields; the latter would challenge the glidepath toward 2% and support a more durable term premium. Available data suggest inflation pressures have moderated from 2022–2023 peaks, and the effective fed funds rate has already eased to around 4.33% through July 2025, according to FRED. That backdrop gives the Fed scope to look through transitory shocks. But if tariffs broaden or become embedded in multiyear policy, supply chain frictions could lift trend inflation and force investors to reassess neutral rates.

Moreover, tariffs interact with fiscal arithmetic. If price levels drift higher, nominal coupon income rises, but so too do nominal borrowing costs for the sovereign when rolling maturing debt—a neutral‑to‑negative dynamic for debt sustainability unless growth or revenues accelerate. UBS’s “not derailing” view is plausible for 2025 base‑case macro outcomes, but it should be stress‑tested against scenarios where tariff implementation is wider or longer than expected. In those cases, a firmer term premium at the 10‑ to 30‑year sector could persist even if the policy rate declines further.

Treasury yields anchor borrowing costs across the economy. Mortgages, investment‑grade credit, small business loans, and municipal finance all key off risk‑free benchmarks. With 10‑year Treasuries near 4.2%–4.3%, conforming mortgage rates are still elevated versus pre‑2020 norms, keeping housing affordability tight and limiting mobility. That friction affects consumption patterns and labor market fluidity—all while unemployment rests at 4.2% (July 2025), a sign of labor markets that have cooled but remain resilient, according to FRED.

On the corporate side, a 3.7%–3.8% yield in the 2‑ to 5‑year Treasury bucket lowers interest expense relative to 2024’s peaks for issuers rolling near‑term maturities, but it is still a higher regime than the 2015–2019 period. Investment‑grade spreads have generally remained contained in 2025 (outside the scope of the datasets cited here), reflecting stable fundamentals and investors’ search for carry. Yet the all‑in cost of capital remains meaningfully higher than in the zero‑rate decade, which disciplines share buybacks, capex, and M&A calculus. For private credit and bank lending, the easing in front‑end rates reduces interest burdens on floating‑rate exposures, helping credit quality at the margin.

Fiscal spillovers should not be ignored. Higher Treasury coupons raise the risk‑free hurdle rate for public‑private partnerships and infrastructure finance. Municipal issuers—often closely tied to the Treasury curve—face higher service costs that can compress budgets. While the macro economy appears to be navigating the transition with unemployment just slightly above 4% and GDP still expanding, today’s rates regime is reshaping micro decisions in ways that may show up in productivity and investment data with a lag.

Three forces loom largest. First, the inflation path relative to expectations: if shelter disinflation stalls or tariffs widen beyond carve‑outs, breakevens could re‑price higher, lifting the back end. Conversely, a renewed disinflation pulse would let term premiums drift lower, pulling the 10‑year toward the high‑3% range. Second, the pace and communication of Federal Reserve easing: FRED’s effective fed funds rate data show 2025 stability around 4.33%, but forward guidance and realized cuts determine whether the 3‑month to 2‑year segment rallies further or stabilizes. Third, the supply‑demand balance for duration: net issuance trajectories, auction takedown dynamics, and foreign official demand will shape how much compensation investors require for holding long bonds.

History counsels humility. In 2019, term premiums were compressed by global QE and negative policy rates abroad; by 2022–2023, inflation surges and balance sheet shrinkage flipped that script. Today’s term premium is positive but not extreme, consistent with a world that has normalized away from emergency policy but still shoulders fiscal and geopolitical risk. If deficits consolidate, the Fed cuts at a measured pace, and inflation trends toward target, the curve could steepen bullishly: 3‑month bills fall faster than long bonds, 2s–10s remain positive, and 10s–30s steepen only modestly. If, instead, deficit fatigue meets inflation frustration, a bear steepening could materialize: long yields rise even as front‑end rates decline—a less comfortable outcome for duration‑heavy portfolios and debt service arithmetic.
