Morgan Stanley Analyzes the Fed's Dilemma: Kohn Day or Bernanke Day

Written by: Rita

Fed Chair Warsh’s hawkish speech at Jackson Hole caused markets to reprice the probability of a September rate hike, while Governor Waller’s dovish remarks the same week sent a markedly different signal. Warsh invoked comparisons to former Vice Chair Kohn and former Chair Bernanke’s tightening styles, posing the question: “Is today a Kohn day or a Bernanke day?” The Bernanke path involves slow, preemptive rate hikes, while the Kohn path entails waiting longer and then hiking more rapidly and aggressively if inflation worsens. Bank of America Securities noted in its Global Economic Weekly report on September 4 that this creates a communication paradox. Warsh, forced to provide more directional guidance than expected to repair credibility damaged by the July press conference, lacked this constraint, allowing Waller to more accurately articulate his state-dependent policy rule.

Bank of America believes that Warsh’s hawkish stance essentially tells the market that the baseline path has shifted onto Cohen’s track. He did not formally commit to rate hikes, but provided more directional guidance than his communication philosophy would suggest.

The key lesson from this communication game is that the clearer the rules are explained, the less need there is to guide the market toward a specific path. Warsh was essentially suggesting that the Fed may have waited too long and should prepare for the Kohn path. Waller, on the other hand, said, “Here’s the roadmap: take the Bernanke path if conditions remain favorable, and switch to the Kohn path if they deteriorate.”

The first tells the market which path is more likely to occur; the second tells the market how the Fed will choose between the two paths. The difference between these two forms of communication stems from how much “skin is in the game.” As chair, Warsh must repair the credibility lost from the July communication misstep and therefore needs to provide stronger directional guidance. As a governor, Waller carries no such burden and can more freely describe conditional outcomes.

Bank of America’s assessment is clear. Warsh, under the guise of rebuilding credibility, ultimately provided more forward guidance. Waller, under the guise of describing conditions, actually gave the market less information about the interest rate path. The tension between these two positions is key to understanding the Fed’s current communication dilemma.

The total U.S. national debt has surpassed $40 trillion, but Bank of America views this as merely a numerical milestone. Markets have shown limited reaction to the absolute level of debt; what truly drives yields are expectations of fiscal deficit changes and the pace of Treasury issuance.

Crossing the $40 trillion mark itself is not a catalyst for the recent rise in long-term yields. What truly matters is interest expenditure. U.S. federal interest payments have now surpassed defense and healthcare spending, accounting for 3.5% of GDP. With current market rates significantly higher than the weighted average rate on existing debt, interest expenditures will continue to rise as debt matures and is refinanced.

Bank of America simulated three scenarios: for every 1 percentage point increase in the debt-to-GDP ratio, interest rates rise by 1, 2, and 3 basis points, respectively. The initial impacts are mild, but the long-term trajectories diverge significantly. The debt-interest rate-debt feedback loop is a slow, gradually accumulating process, not an immediate risk.

Bank of America expects the European Central Bank to raise rates by 25 basis points in September, bringing the deposit rate to 2.50%. Based on assumptions from mid-August, inflation forecasts have changed little, suggesting a third rate hike this year is possible but not guaranteed. Bank of America believes that after the September hike, the ECB will have completed this tightening cycle and will shift toward rate cuts in 2027.

Energy prices remain the greatest uncertainty. If energy prices as of September 1 are used, synthetic energy prices in 2027 would be nearly 5% higher than the June baseline. If the ECB’s alternative scenario shows 2027 and terminal core inflation 10 basis points higher than the June baseline, the market would interpret this as a signal of increased likelihood of a rate hike in December. Bank of America still views the threshold of a total 75-basis-point hike as high, requiring sustained increases in energy prices to be realized.

Bank of America has slightly raised its UK growth forecast for 2026 to 1.2%, reflecting stronger-than-expected economic performance in the first half of the year. The 2027 growth forecast has been lowered to 1.2% due to elevated energy prices and policy uncertainty ahead of the autumn budget. Inflation is now expected to peak at 3.5% in November, higher than previous forecasts.

Bank of America expects the Bank of England to hold rates steady through 2026 and cut by 25 basis points to 3.50% in November 2027. Uncertainty surrounding energy shocks means the risk of further rate hikes remains, with meetings in November, December, and February all still "live." Bank of America believes the market is pricing in too hawkish a stance on the last three rate hikes.

The Philippines' 2026 fiscal deficit may widen to 6.1% of GDP, higher than the government’s previous forecast of 5.5%. The main reasons are slower revenue growth (projected at 6%, compared to the government’s forecast of 8%) and a slower GDP growth rate (2.5% versus the government’s forecast of 3.5% to 4.5%). Interest payments are consuming an increasing share of the budget, projected to reach 15% in 2026—the highest level since 2014.

In Central and Eastern Europe, the natural gas price shock represents a real risk, and market pricing for interest rate hikes may be too high. The pass-through of natural gas prices to consumer prices is slow and uneven, with a lag of 6 to 12 months and significant variation across countries. The Czech Republic is most affected by wholesale gas prices, followed by Poland, while Hungary and Romania are protected by administrative pricing. Bank of America expects the Czech National Bank to raise rates at most one more time (in November, by 25 basis points), while the Polish National Bank will hold rates steady.

Bank of America’s global outlook presents a clear picture: the U.S. is caught in a communication paradox, with its debt trajectory slowly deteriorating; Europe stands on the threshold of its final rate hike; the U.K. is waiting out the energy shock; emerging markets face their own structural constraints. This is a global economic landscape without a unifying theme—divergence is the dominant narrative.
