“You are that great Fabius, who alone restores our state by delaying” 
- Virgil, Aeneid, Book VI

In 217 BC, after Rome's disastrous defeat to the Carthaginians at Lake Trasimene, the Senate appointed Quintus Fabius Maximus as dictator and Rome’s protector. However, rather than offer Hannibal the decisive battle Rome expected, Fabius shadowed the Carthaginian army across Italy, harassing its supply lines while refusing to engage.

The strategy violated Rome's ideal of virtus (martial courage) and proved deeply unpopular. Mocked by soldiers and senators alike, Fabius earned the nickname “The Delayer”. History would, however, eventually judge him rather differently.

The same tension between patience and perceived indecision currently hangs over the Federal Reserve (Fed).

On 29 July, the Fed met for the second time under Kevin Warsh. The policy rate remained at 3.5%, but three regional Fed presidents dissented in favour of a hike; only the sixth such three-way dissent since the mid-1990s.

At his press conference, Warsh rejected the idea that the Committee had been inert, telling reporters there was “nothing inertial about our discussions, our policy, or our strategy.” He also argued that reducing forward guidance would let markets respond directly to incoming data rather than Fed commentary, allowing investors to "play the ball, not the referee". Higher nominal and real Treasury yields were, in his words, not something to resist but a source of information about how markets were interpreting the outlook.

This approach has persisted despite inflation remaining above the Fed's 2% target for more than five years, an unprecedented run in the inflation-targeting era and the backdrop cited explicitly by the Committee's three dissenters.

Dallas Fed President Lorie Logan argued inflation was not yet on a sustainable path back to target and that a resilient labour market gave policymakers room to tighten rather than wait. Cleveland's Beth Hammack and Minneapolis's Neel Kashkari made similar arguments.

The reaction from Treasuries

Bond markets reacted swiftly. The 30-year Treasury yield rose to 5.3%, its highest level since 2007, while the 10-year reached its highest since early 2025, as investors demanded greater compensation for duration. Much of the immediate commentary interpreted the meeting as a blow to the Fed's credibility. The Wall Street Journal, for example, quoted one rates strategist describing it as a “classic central-bank credibility shock”. The echo of Fabius's own nickname cannot be ignored: The Delayer - after all, was initially coined as an insult.

The bond market is, however, nuanced. Since the start of the year, nominal 10-year Treasury yields have risen by 57 basis points, almost entirely because of higher real yields. Ten-year break-evens are little changed despite higher oil prices, while the yield curve also remains considerably flatter than at the start of the year.

In this context, the bond sell-off could reflect stronger real growth rather than renewed inflationary concerns. Indeed, one could argue that Warsh is not displaying indecision but just allowing markets to do more of the informational work themselves. The strategy only looks indecisive if it ultimately proves unsuccessful.

Macro data remains mixed

The macro situation is also equally nuanced. Headline PCE inflation eased to 3.7% in June from 4.1% in May, though much of the improvement reflected lower energy prices during the temporary Middle East ceasefire. Core PCE, at 3.3%, suggests disinflation is continuing, but only gradually. The labour market, meanwhile, is more mixed than robust. Unemployment fell to 4.2%, but largely because participation dropped to its lowest since 2021, while payroll growth has slowed sharply to just 57,000, with the two prior months revised down by a combined 74,000. Neither set of indicators are giving the Fed a clear signal.

Fabius spent years being mocked before history judged him differently – as illustrated by Virgil’s comment in the Aeneid two centuries later. Whether Warsh's strategy earns the same verdict remains unknowable this early in his tenure. For now, markets appear to be pricing scepticism as opposed to patience.

For the Polar Capital Financial Credit Fund, the implications remain relatively contained. Overall duration is 2.9 years, limiting sensitivity to the recent rise in long-dated Treasury yields. While higher US real yields may continue to generate periods of volatility across global fixed income, our relatively short duration provides a degree of insulation should markets continue to test the Fed's resolve. More broadly, if Warsh's strategy succeeds, with markets doing more of the adjustment, the environment should be supportive for credit.
