Bank of America said Federal Reserve Chair Warsh’s hawkish speech at Jackson Hole effectively signaled to markets that the default policy path has shifted toward a later but sharper tightening track.
In its global economics weekly published on Sept. 4, BofA said Warsh’s remarks led markets to reprice the probability of a September rate hike, while Federal Reserve Governor Waller delivered a much more dovish message in the same week. Warsh framed the debate by comparing the rate-hike styles associated with former Vice Chair Kohn and former Chair Bernanke, asking whether this was a "Kohn day or a Bernanke day." In the report’s description, the Bernanke path is gradual and preemptive, while the Kohn path waits longer and then moves faster and more aggressively if inflation worsens.
Fed messaging split centers on how much guidance to give
BofA said the contrast has created a communication paradox. In its view, Warsh was forced to provide more directional guidance than markets expected because he needed to repair credibility damaged by the July press conference. Waller did not face that constraint and could more accurately describe a state-dependent policy rule.
The bank said Warsh did not formally commit to a rate increase, but he still gave markets more directional guidance than his own communication philosophy would normally imply. BofA’s conclusion was direct: Warsh’s hawkish stance was, in substance, a message that the default path had already moved onto the Kohn track.
Waller’s approach was different. BofA summarized it as a roadmap: if conditions stay favorable, policymakers follow the Bernanke route; if conditions deteriorate, they shift to the Kohn route. One message tells markets which path is more likely. The other explains how the Fed would choose between the two.
The report tied that difference to how much credibility risk each official is carrying. As chair, Warsh had to respond to the reputational damage from the July communication misstep and ended up offering stronger forward guidance. As a governor, Waller had more room to talk about conditionality without taking on the same burden.
More transparency can mean less commitment
BofA said the central lesson from this messaging contest is that the clearer policymakers are about the rule, the less they need to guide markets toward one specific outcome. In that framework, Warsh was hinting that the Fed may already have waited too long and that markets should be ready for the Kohn path. Waller, by contrast, laid out the conditions under which either path could be chosen.
The bank’s reading was that Warsh, under the banner of restoring credibility, ended up offering more forward guidance, while Waller, under the banner of describing conditionality, gave markets less information about the likely rate path. BofA said that tension is key to understanding the Fed’s current communication problem.
$40 trillion in U.S. debt is not the immediate yield catalyst
On U.S. fiscal conditions, BofA said federal debt topping $40 trillion is mainly a numerical milestone. The market’s reaction to the absolute debt stock has been limited, and the more important drivers of yields are changes in fiscal deficit expectations and the pace of Treasury issuance.
The bank said the move above $40 trillion is not, by itself, the catalyst for the recent rise in long-end yields. The more important issue is interest expense. According to the report, U.S. federal interest payments have already surpassed defense and Medicare spending and now account for 3.5% of GDP. Because current market rates are well above the weighted average rate on outstanding debt, interest costs are likely to keep rising as debt is rolled over.
BofA modeled three scenarios in which rates rise by 1, 2, and 3 basis points, respectively, for every 1 percentage point increase in the debt-to-GDP ratio. The initial effect is mild, the report said, but the long-term paths diverge materially. It described the debt-rate-debt loop as a slow but cumulative process rather than an immediate risk event.
ECB seen delivering a 25-basis-point move in September
BofA expects the European Central Bank to raise rates by 25 basis points in September, taking the deposit rate to 2.50%. Based on assumptions from mid-August, the bank said inflation forecasts have not changed much, leaving room for a third hike this year but stopping short of any commitment.
Its base case is that the September move would mark the end of the current tightening cycle, with the ECB turning to rate cuts in 2027.
Energy prices remain the biggest uncertainty. Using prices as of Sept. 1, BofA said its synthetic 2027 energy price measure would be nearly 5% above the June baseline. If the ECB’s alternative scenario shows both 2027 inflation and terminal core inflation 10 basis points above the June baseline, markets would read that as a stronger signal for a possible December hike.
Even so, BofA said the bar for a total of 75 basis points of additional tightening remains high and would require sustained energy-price increases.
UK outlook shifts on growth, inflation, and rates
BofA slightly raised its 2026 UK growth forecast to 1.2%, reflecting stronger-than-expected economic performance in the first half. It cut its 2027 growth forecast to 1.2% because of elevated energy prices and policy uncertainty ahead of the autumn budget.
The bank now expects UK inflation to peak at 3.5% in November, above its previous forecast.
On rates, BofA expects the Bank of England to stay on hold through 2026 and then cut by 25 basis points in November 2027, taking the policy rate to 3.50%. It also said uncertainty around the energy shock means hike risk is still present, leaving the November, December, and February meetings live. BofA added that market pricing for the next three hikes is too hawkish.
Philippines deficit widens, Central and Eastern Europe remains uneven
In emerging markets, BofA said the Philippines’ 2026 fiscal deficit could widen to 6.1% of GDP, above the government’s earlier 5.5% projection. The bank pointed to slower revenue growth, which it sees at 6% versus the government’s 8%, and weaker GDP growth of 2.5% versus the government’s 3.5% to 4.5% range.
Interest payments are taking up a larger share of the budget, the report said, and are expected to reach 15% in 2026, the highest level since 2014.
For Central and Eastern Europe, BofA said the gas-price shock is a real risk and that market pricing for the scale of future hikes may be too high. Pass-through from gas prices to consumer prices is slow and uneven, with lags of six to 12 months and meaningful differences across countries.
BofA said the Czech Republic is the most exposed to wholesale gas prices, followed by Poland, while Hungary and Romania are shielded by administrative pricing. It expects the Czech central bank to deliver at most one more hike, a 25-basis-point move in November, while Poland’s central bank is expected to keep rates unchanged.
BofA’s global picture is one of divergence
The report’s broader message is that the global economy does not currently have a single unifying theme. The U.S. is wrestling with a Fed communication paradox and a slowly worsening debt path. Europe is near what BofA sees as the final hike of the cycle. The UK is waiting through an energy shock. Emerging markets are constrained by their own structural issues.
