La dette américaine attire soudainement une demande plus faible alors que 10 000 milliards de dollars doivent être refinancés cette année dans un contexte de guerre avec l'Iran. « Le marché obligataire reste invaincu »
La guerre de Donald Trump contre l'Iran se heurte aux investisseurs en dettes américaines, qui ont démontré un appétit moindre pour les titres du Trésor alors que les espoirs d'une fin rapide du conflit s'estompent.
Cette semaine, les ventes aux enchères de bons du Trésor à deux, cinq et sept ans ont toutes attiré une faible demande, obligeant les rendements à augmenter plus que prévu. C'est un contraste frappant avec le mois dernier, lorsque l'offre d'un Trésor a connu la demande la plus élevée de l'histoire des ventes aux enchères de 30 ans.
L'extrémité courte de la courbe des taux est soumise à une pression supplémentaire, les prix du pétrole en hausse stimulant les perspectives d'inflation et mettant un frein aux nouvelles baisses de taux de la Réserve fédérale, les probabilités d'une hausse des taux augmentant également.
Parallèlement, le coût de la guerre américaine contre l'Iran aggrave la situation de la dette, des rapports indiquant que le Pentagone demande 200 milliards de dollars au Congrès. Non seulement l'armée a épuisé une grande partie de ses munitions les plus coûteuses qui doivent être reconstituées, mais les attaques iraniennes ont endommagé ou détruit des aéronefs, des systèmes radar et des bases américains.
« Le marché obligataire du Trésor américain a finalement réagi à la guerre au Moyen-Orient, donnant son évaluation de la gravité du choc énergétique et de l'effet de la guerre sur le déséquilibre budgétaire américain et l'inflation », a déclaré mercredi Joseph Brusuelas, économiste en chef de RSM, en soulignant une augmentation notable de la volatilité du marché obligataire et une prime de risque croissante pour acheter des titres du Trésor.
« Les préoccupations des investisseurs incluent une position budgétaire américaine insoutenable, un risque inflationniste croissant et une incertitude grandissante quant à la guerre », a-t-il ajouté, alors que le rendement à deux ans a dépassé 4,0 % cette semaine, tandis que le rendement à 10 ans a grimpé au-dessus de 4,4 %.
L'indice MOVE qui suit la volatilité sur le marché des Trésors a grimpé à des niveaux cohérents avec l'instabilité des prix et les dysfonctionnements de la politique, a noté Brusuelas.
Si l'incertitude persiste, cela pourrait déclencher un stress de financement plus large sur les marchés de la dette qui étaient déjà sous pression en raison des inquiétudes concernant le crédit privé, a-t-il prédit.
L'avertissement souligne le rôle des « vigilants obligataires », un terme inventé par Ed Yardeni, un vétéran de Wall Street, dans les années 1980, se référant aux traders qui ont protesté contre d'énormes déficits en vendant des obligations pour faire monter les rendements.
Les ventes antérieures ont maîtrisé les présidents, y compris Trump, qui a retiré son bras de fer commercial l'année dernière après que le marché obligataire est devenu « yippy ». Avec les États-Unis désormais engagés dans une guerre réelle, les vigilants obligataires pourraient de nouveau faire valoir leur poids.
« Le besoin de dépenses supplémentaires pour financer la guerre augmenterait la dette américaine, déclenchant une vente obligataire alors que les investisseurs exigent une compensation supplémentaire pour couvrir les pertes potentielles », a déclaré Brusuelas. « Les taux à long terme, tels que les taux hypothécaires à 30 ans, sont basés en partie sur le rendement de référence américain à 10 ans. Le plus important : Le marché obligataire reste invaincu. »
Quatre modèles AI de pointe discutent cet article
"Rising Treasury yields reflect Fed rate-cut expectations evaporating due to inflation fears, not an imminent fiscal crisis or bond market 'defeat.'"
The article conflates three distinct problems—Iran war costs, Treasury auction weakness, and inflation—into a unified 'bond vigilante' narrative that oversimplifies. Yes, 2-year and 10-year yields rose this week. But the article omits: (1) auction 'weak demand' is relative—Treasury auctions still clear, just at higher yields, which is normal price discovery, not crisis; (2) the $10T rollover figure is misleading—it's annual refinancing of maturing debt, not new issuance; (3) the $200B Pentagon request is speculative ('reports seeking'), not appropriated; (4) oil prices affect inflation expectations but don't automatically trigger Fed rate hikes if growth softens. The MOVE index spike is real but often mean-reverts. The strongest signal is the 2-year yield topping 4.0%—that *does* suggest rate-cut expectations have collapsed—but that's about Fed policy, not fiscal crisis.
If the bond market were truly 'undefeated,' yields would have spiked far more sharply and auction demand would have collapsed entirely; instead, Treasuries are still clearing at modest yield premiums, suggesting investors still view U.S. debt as the safest asset class and are simply repricing risk, not abandoning the market.
"The traditional 'flight to safety' in Treasuries has broken down, as investors now view U.S. sovereign debt as a source of risk rather than a hedge against it."
The article highlights a critical 'fiscal-monetary collision.' With $10 trillion in debt maturing this year—roughly 30% of total outstanding—the U.S. is losing its 'safe haven' status as geopolitical risk usually drives yields down, not up. The jump in 2-year yields to 4.0% suggests the market is pricing in 'fiscal dominance,' where the Fed cannot cut rates due to war-induced energy inflation, while the Treasury must issue more debt to fund a $200 billion Pentagon request. This 'twin-engine' pressure of rising supply and falling demand creates a structural bear steepener (long-term rates rising faster than short-term), threatening the 30-year mortgage market and private credit valuations.
If the conflict triggers a global recession, the 'flight to quality' may eventually overwhelm fiscal concerns, causing a massive short squeeze that collapses yields regardless of the deficit.
"The Treasury market is beginning to price a higher long-run term premium driven by war-related fiscal pressures and energy-driven inflation, which will push yields—and borrowing costs—meaningfully higher unless policy or sovereign demand intervenes."
Recent weak two-, five- and seven-year auctions and a spike in the MOVE index suggest the market is repricing a higher term premium as oil-driven inflation risk and the prospect of sustained war spending collide with a $10 trillion rollover year. That combination raises short- and intermediate-term Treasury yields, pushes mortgage and corporate borrowing costs higher, and tightens financial conditions — a potential drag on growth if persistent. The article understates technical offsets (Treasury cash balances, choice of bill vs. coupon issuance), the Fed’s ability to lean against dysfunction, and the role of foreign/sovereign demand that can quickly reverse selloffs.
This could be a short-lived spike: the Fed and Treasury have tools (reserve management, temporary issuance mix, and dealer backstops) and global demand for safe dollars can reassert itself, muting long-run fallout. War-related premiums often compress once combat stabilizes or funding is absorbed into regular issuance.
"Auction softness reflects episodic war uncertainty atop chronic fiscal risks, not a structural demand collapse—global buyers and Fed tools provide resilience unless deficits explode."
Recent weak demand at 2-, 5-, and 7-year Treasury auctions—contrasting last month's record 30-year bid-to-cover—has lifted yields (2-year >4%, 10-year >4.4%) amid US-Iran war fears, $10T debt rollover needs, $200B Pentagon ask, and oil-spurred inflation delaying Fed cuts. MOVE index spike signals volatility, reviving bond vigilante talk. But context missing: fiscal woes (ongoing $2T deficits) predate conflict; auctions remain liquid with high bid-to-covers historically; global safe-haven flows (e.g., Japan, China holdings) persist. Short-term pressure likely, but no evidence of sustained risk premium yet—watch Q3 issuance for confirmation.
If Iran conflict escalates into prolonged war, combining $200B+ costs with oil at $100+/bbl could ignite sticky inflation, force Fed hikes, and balloon deficits to $3T+, empowering vigilantes to push 10-year yields toward 5% and sparking credit stress.
"Fiscal dominance requires stagflation; recession breaks the thesis entirely."
Gemini flags 'fiscal dominance' but misses the timing problem: the $200B Pentagon request isn't appropriated yet—it's speculative. More critically, if oil-driven inflation triggers recession (as ChatGPT's counterargument suggests), the 'twin-engine' thesis collapses because deflationary pressure and flight-to-quality would crush long rates faster than fiscal concerns lift them. The bear steepener only persists if growth stays resilient *and* inflation sticky—a narrow path requiring both conditions simultaneously.
"The Treasury can mitigate auction weakness by shifting issuance to the short end of the curve, delaying a true fiscal crisis."
Gemini and Grok are overstating the 'fiscal dominance' threat by ignoring the Treasury’s ability to manipulate issuance. If the $10T rollover becomes toxic, Yellen can pivot to T-bills (short-term debt) to bypass the long end of the curve, effectively 'stealth easing.' This prevents the 30-year mortgage spike Gemini fears. We aren't seeing a 'failed' market; we're seeing a duration strike. The real risk isn't a lack of buyers—it's the Fed being forced to restart QE to monetize this specific $200B war-drain.
"Pivoting to T-bills to avoid long-term yield stress risks creating a reserve drain and money-market liquidity crisis that would force Fed intervention and tighten conditions."
Gemini argues Treasury can pivot to T-bills to blunt long-end stress, but that move creates a different, underappreciated risk: a massive shift into short bills would rapidly drain reserve balances, spike money-market rates (repo, CP, SOFR), overload dealers’ balance sheets, and force the Fed into emergency liquidity operations or renewed reserve expansion—precisely the kind of policy/market mess that would tighten financial conditions even if long yields stay subdued.
"Money market funds' massive AUM can absorb T-bill surges, mitigating ChatGPT's financial tightening risks."
ChatGPT flags valid T-bill pivot risks like reserve drains and SOFR spikes, but ignores $6.5T money market funds (up 20% YoY) primed to absorb issuance—they hoovered $1.2T bills in 2023 sans crisis. Reserves still $3.2T; this buffers tightening. Unmentioned second-order: bill flood flattens curve further, hurting banks' NIMs amid deposit flight.
