Art Laffer on Bond Meltdown at the 5% Threshold: Rates, Oil and Markets

On Wednesday September 23 the U.S. 10-year Treasury yield jumped to 5.09%, the highest since 2007, with the 30-year pushing toward a two-decade peak as investors priced in rates staying higher for longer. The 5% line matters psychologically because it re-anchors mortgage pricing, corporate funding costs and the debate over whether the Treasury should try to suppress the long end of the curve, and it turned a U.S. move into a global bond sell-off.

Art Laffer does not read the sell-off as a classic inflation scare. In his split of the nominal yield into expected inflation and expected real return, the TIPS-based breakeven suggests inflation expectations are flat to slightly lower, while the real component has stepped up materially; for him that rise is a strength signal rather than a warning of overheating.

Contagion was rapid. Live market wraps in London described sliding prices not only in Treasuries but across European and Asian sovereign bonds, with oil back near the $100 mark amplifying the tension. CNBC and Yahoo Finance flagged intraday pushes toward $105 this week, linking the energy shock directly to the pressure on duration.

Laffer still sees the underlying U.S. economy as unusually robust. The PMI reading cited by Reuters stayed well above the 50 expansion threshold, the strongest since July 2021, and all twelve FOMC governors remaining constructive on growth through 2027 reinforces the view that the official outlook aligns with his strong-economy read.

He ties part of that robustness to a sudden shift in migration dynamics. After adjusting for a drag of roughly 200,000 jobs per month linked to slower migration flows, headline payrolls look sturdier than they first appear, with equity performance and corporate earnings fitting the same narrative.

At the center is what the Fed should actually target. Referencing Chicago Fed President Austan Goolsbee's London remarks from two days earlier on persistent supply shocks, Laffer argues the central bank's job is to preserve the long-run value of the dollar. He points to long-run yield data from 1780 to 1913 assembled by Jeremy Stein and Jeremy Schwarz and says controlling the monetary base and the balance sheet matters more than tactical rate tweaks.

That framework explains his praise for new Fed Chair Kevin Warsh, whom he ranks alongside Paul Volcker and Alan Greenspan as among the best prepared to lead the institution. In Laffer's view Warsh understands base control versus inflation expectations correctly, and the recent calm in TIPS breakevens is an early confirmation of that approach.

He also downplays the short-rate confusion between the discount rate and the federal funds rate, describing the 25-basis-point gap as a routine technical buffer that discourages banks from borrowing from the Fed outside crises. Raising that spread alone, he argues, does not dictate where the 10-year yield settles.

The oil and diesel file is a separate chapter for Laffer. With U.S. diesel at historic highs, talk of banning exports is on the table, but he rejects it outright. If truckers want domestic diesel more intensely they should outbid foreign buyers; the highest price is what incentivizes refiners to make more, and comparative advantage is better discovered by markets than by edict.

Reporting from Reuters and CNBC aligns with that caution. The U.S. exported a record 1.6 million barrels per day of diesel in August, and analysts warn a ban would tighten global supply, deepen Europe's shortfall and could even force lower refinery utilization, leaving domestic prices no lower on a durable basis.

Fragility in the supply chain is magnified by the Strait of Hormuz and the Red Sea. In his UN General Assembly speech President Trump claimed the Navy escorted between 22 and 37 vessels a day, pushing more than one billion barrels through, one of the largest flows since the conflict began. Laffer notes that protecting each shipment with naval power adds an implicit cost per barrel and that a durable peace would erase that premium.

That is where the Iran file links back to rates and oil. At the UN, Trump kept both options open — quickly dismantling the adversary or striking a sweeping deal right after the midterms — while NBC News reported Tehran signaling willingness to deal before the vote. Laffer argues the design problem is not pressuring the country in the abstract but shifting the personal incentives of the decision maker, since broad sanctions alone have not altered behavior.

Midterm projections shape the politics around that deal. Prediction markets price a high chance of Democrats taking the House and about 60% for the Senate, yet Laffer expects limited near-term change in economic legislation. Key provisions on work requirements, school choice and permanence of recent tax cuts are now law and shielded by veto power, with only narrow channels such as a Supreme Court vacancy highly sensitive to Senate control.

He also notes President Trump will enter a lame-duck phase off the ballot for two years after the midterms, with 2028 shaping up as a fresh contest. Building an economic agenda solely around opposition to Trump, he argues, does not produce a coherent program, which helps explain why macro framework continuity may matter more to markets than daily political noise.

The productivity debate is Laffer's favorite ground. With U.S. manufacturing productivity rising around 2% annualized, artificial intelligence could deliver an abundance scenario. He uses an apple harvest analogy: producing more goods and services does not fuel inflation, it dampens it, and as Goolsbee hinted, growth driven by supply helps bring expected inflation down.

From there comes the Laffer Curve question. If AI makes capital and labor massively more productive, does the curve itself shift? Not directly, Laffer says. Higher productivity lifts the value of the capital stock and the income base, but the peak of the curve is determined by the progressivity and structure of rates themselves; technology widens the base, it does not rewrite the logic.

Finally the wealth-tax debate turns concrete with California. A residency-based levy anchored on January 1 2026 would, Laffer argues, simply push billionaires out of the state toward Nevada and similar jurisdictions, and focusing on a single year for figures like Jeff Bezos misleads, as he contended in a debate with Gabriel Zucman. Doubling that levy would not automatically flow to a teacher in Queens, since school funding rests mainly on local property taxes, and he contends higher incomes from stronger productivity will make individual opportunity more attractive than collectivist pressure.
