NextFin News - The sharp rise in U.S. Treasury yields is running out of steam, and the reason matters more than the move itself. Marko Papic, head of GeoMacro at BCA Research, argues the selloff was driven by geopolitical reflex rather than a structural break in America's fiscal picture — a call that treats the bond market's recent panic as a mean-reverting risk premium, not a regime change. Speaking on September 24, 2026, Papic said the pressure bonds have placed on the White House is nearing an end.
The judgment splits the market in two. On one side stands the tape: after the Federal Reserve raised its benchmark rate by 25 basis points on September 16 — the first hike since 2023 — the 10-year Treasury yield climbed back above 5% and closed at its highest level in 19 years. On the other side stands Papic's framework, set out in a September 1 research note titled "Trading Bonds On Vibes" and reiterated in the latest interview: bonds have been "alarmed by the incoherent US geopolitical policy," with oil as the conduit between geopolitics and rates. If the driver is a headline-driven risk premium, it fades when the headlines do. If it is fiscal dominance, it does not. Which one it is determines whether the next trade is a reversion or a trap.
The Move: A Hike, a Spike, and a Market That Overreacted
The sequence is straightforward. The Fed's Federal Open Market Committee voted 12-0 to lift the federal funds rate to a target range of 3.75%-4.00%, a quarter-point increase that Fed Chair Kevin Warsh framed without ambiguity:
"Inflation is too high and has been for too long."The market reaction was immediate and broad. The Dow Jones Industrial Average fell 631 points, or 1.2%, as Warsh began his press conference, and the 10-year yield rose back above 5%, closing there for the first time since 2007. The widening conflict in the Middle East, which pushed oil prices higher and lifted inflation expectations, was cited as a key input into the decision.
That is the first-order story, and it is the one most of the market is trading: inflation stayed hot, the Fed hiked, yields followed, and the transmission to financial conditions has only just begun. A sustained 5%-plus 10-year yield touches everything — mortgage rates, corporate borrowing costs, the discount rate on growth stocks, the debt-service burden on a federal budget where interest expense is already among the largest line items.
But Papic is not trading the first-order story. His argument is that the bond market has been pricing a geopolitical risk premium on top of the rate path, and that premium is now exhausted. In his September note, he wrote that
"bonds are trading on 'vibes,'"and identified the mechanism explicitly:
"Oil prices are obviously the conduit between that policy and the markets."The distinction is not semantic. A geopolitical premium is cyclical by construction — it spikes on escalation and decays on de-escalation. A structural repricing, driven by a permanent rise in the term premium or a loss of confidence in U.S. creditworthiness, would not decay on its own. The entire trade rests on getting that classification right.
Why This Is Cyclical, Not Structural
Three pieces of evidence support the cyclical read, and each one attacks a different pillar of the structural-bear case.
First, the timing of the yield spike lines up with the escalation of the Middle East conflict and the oil-price reaction, not with any deterioration in Treasury auction demand or a credit event. When bond markets are pricing a genuine fiscal-break scenario, they show it in the plumbing: weak auctions, a widening bid-to-cover gap, a term premium that rises across the curve regardless of the headline cycle. Papic's note argues the opposite — that growth remains robust, which is inconsistent with a solvency panic. A market worried about America's ability to service its debt does not coexist comfortably with strong growth and record equity valuations.
Second, the fiscal channel that should be scaring long-duration investors is, in Papic's reading, actually improving. He has argued that the Trump administration's tariffs function as a tax increase paid by U.S. consumers, and that the bond market has begun to price in the deficit-easing effect of that revenue.
"The main reason in my view is that the bond market has realized that the income from the Trump tariffs eases some of the fiscal deficit,"he said in a prior interview. That framing inverts the bear case: rather than fiscal profligacy forcing yields higher, a politically unpopular form of fiscal consolidation is quietly reducing the deficit.
Third, Papic has been willing to act on the cyclical call. He advised clients with a long-term focus to
"begin nibbling at the hated bonds,"and he has described the fiscal-policy theme — the one secular argument that should keep long-duration investors awake — as the one that
"does not bother us all that much."That is a strong statement from a strategist whose entire framework is built on geopolitical risk. When the geopolitical specialist tells you the geopolitics, not the fiscal math, is the driver, the implied trade is a reversion.
The evidence floor for a cyclical call requires demonstrated mean reversion, a short-term driver, and historical analogs. The short-term driver here is the geopolitical risk premium transmitted through oil. The mean-reversion pattern is visible in the speed of the move: the 10-year yield's climb above 5% came in a matter of sessions after the hike, which is the signature of a positioning and sentiment shock rather than a slow reassessment of credit fundamentals. The historical analog is the pattern Papic himself has documented — risk premiums that spike on geopolitical shocks and decay once the conflict either resolves or becomes the new normal.
The Counter-Thesis: This Time the Fiscal Channel Is Real
The strongest case against Papic does not attack his geopolitics; it attacks his fiscal math. The United States is running deficits that would have been unthinkable a decade ago. Interest expense is consuming a growing share of federal revenue. The Fed's institutional independence is under open political pressure, and the administration's stated preference is for lower long-term rates achieved through personnel and persuasion rather than through fiscal consolidation. In this reading, the bond market is not overreacting to a headline — it is finally demanding a term premium commensurate with a world in which fiscal dominance is the regime, not the exception.
This counter-thesis is not a strawman. It is the position Papic himself has flagged as the specific risk that would break his call. The tariff revenue that underpins his "deficit is improving" argument rests on a legal foundation that could be removed.
"Ironically, this is where I see the biggest short term risk: That the U.S. Supreme Court could throw out the tariffs as unconstitutional,"he has said. The consequence would be direct and mechanical:
"Because then the bond market could worry more about the fiscal situation again, as it did right after President Trump was elected, and yields would go up."
His own caveat is the counter-thesis compressed into a single sentence:
"If Treasury yields rise substantially again, equity markets will run into trouble."Note what that concedes — that the equity market's current valuation is contingent on the bond market staying calm. If the 10-year yield makes a new high from here, it is not merely a bad bond trade; it is a signal that the market is pricing something structural, and the risk-asset complex built on lower discount rates becomes vulnerable.
There is also the oil channel, which cuts in both directions. Papic's framework makes oil the transmission mechanism between geopolitics and yields. Contained conflict pulls yields down; an escalation that sends oil sharply higher feeds inflation back into the picture and forces the Fed to stay tight for longer. The same pipe that carries his thesis can carry its refutation.
The Second-Order Trade the Market Has Not Priced
The consensus read of a peaking 10-year yield is unambiguously bullish for risk assets: lower discount rates lift growth stocks, ease financial conditions, and support housing. Papic's call, taken at face value, is a version of that trade. But there is a second-order implication that the market has not fully absorbed, and it is conditional in a way the consensus is not.
A peaking yield is bullish for equities only if it peaks because geopolitical risk is fading — not because growth is rolling over. If the 10-year yield tops out because the economy is weakening, the signal inverts: the Fed cuts into a slowdown, earnings expectations fall faster than discount rates, and the equity market declines even as yields decline. That is why the growth assumption in Papic's framework is doing far more work than it appears to. He has argued that investment in data-center construction is contributing roughly one percentage point to U.S. growth, and that this AI-driven capital expenditure will act as a bridge, holding the economy up for the next twelve months while households transition from cash-driven to leverage-driven consumption. Remove that bridge, and the "Goldilocks" scenario — falling yields with stable growth — becomes a slowdown scenario with falling yields.
This is the expectation gap. The market is pricing "peaking yields = bullish." The more precise statement is "peaking yields are bullish only if the peak is geopolitical, not cyclical-growth." That distinction is the difference between a long-duration rally that lifts everything and one that rotates leadership from cyclicals into defensives.
What Would Prove the Call Wrong
A judgment without a falsifying signal is a wish. For Papic's thesis, the line in the sand is the post-hike peak. If the 10-year Treasury yield closes above the level it reached after the September 16 decision — back above 5% — for multiple consecutive sessions, and especially if that move is accompanied by a fresh, sustained spike in oil prices, the "geopolitical vibes" explanation no longer holds. At that point the move is being driven by something structural: fiscal, inflationary, or both. The call is then wrong, and the position flips from "nibbling at hated bonds" to defending duration.
The specific signal to watch is therefore simple: a sustained close of the 10-year yield above its post-hike peak, confirmed by oil moving sharply higher on escalation rather than lower on de-escalation. That combination would tell you the premium is not fading — it is being repriced for a longer, hotter conflict, and the fiscal channel Papic dismissed is waking up.
Outlook: Three Horizons, Three Trades
Split by time horizon, the picture is not one verdict but three.
In the short term, yields are a function of headlines and positioning. The base case is that the 10-year yield has made its cyclical high and will grind lower as the geopolitical risk premium drains out. The trigger for this leg is de-escalation in the Middle East or a stabilization in oil prices. The upside surprise would be a faster-than-expected resolution that sends the 10-year back toward the low-4% range.
In the medium term, yields are a function of whether AI capital expenditure can hold growth up while households lever their balance sheets back up. This is the bridge Papic has described, and it is the most fragile part of the thesis. If data-center investment slows before household leverage picks up, the economy loses its growth engine and the Fed faces a slowdown with sticky inflation — the worst combination for bonds.
In the long term, yields are a function of whether the U.S. fiscal path is sustainable without financial repression. Papic's call is explicitly a short-to-medium-term cyclical call, and it should be judged on that horizon. It is not a claim that the deficit has been solved; it is a claim that the bond market overreacted to a headline. Those are very different statements, and only the second one is being tested now.
The scenarios, then, are these. Base case: de-escalation, stable oil, 10-year yield drifting lower — duration performs. Upside case: a rapid geopolitical resolution sends yields toward prior lows, and the rally broadens to risk assets. Downside case: the Supreme Court strikes down the tariffs, or oil spikes on escalation, and the 10-year retests and exceeds the post-hike peak — at which point the trade inverts and the structural bears take over.
The takeaway is narrower than the headline suggests. Papic is not betting that America's fiscal math has improved. He is betting that the bond market priced a geopolitical shock as if it were a fiscal break, and that the error will correct. If the next headline is worse than the last, the reversion trade becomes a trap — and the 5% level on the 10-year yield is the line that tells you which world you are in.
