Central Banks' Words vs. Actions: ECB Hikes Decisively, BOE and Fed Lag

Overview

This report uses Natural Language Processing (NLP) models to quantitatively analyze the relationship between the 'hawkish rhetoric (bark)' and 'actual rate hike actions (bite)' of the European Central Bank (ECB), Bank of England (BOE), and Federal Reserve (Fed). Nomura Securities believes that there is significant divergence in words versus actions among the three major central banks currently: the ECB has rapidly translated hawkish rhetoric into actual rate hikes, while the BOE and Fed have shown significant lags in action.

Core views

ECB walks the talk, accelerating rate hikes: The ECB's hawkish rhetoric index (ECBspeak) rose the fastest among the three central banks, currently reaching 20.7. Compared to the previous cycle, the ECB has been more decisive this time, raising rates by 25 basis points to 2.25% this month. Due to concerns about second-round inflation effects, Nomura's European economics team expects the ECB to raise rates by another 25 basis points in September and December 2026, and March 2027. BOE acts slowly, possibly no hikes this year: The BOE's hawkish rhetoric index rose more slowly, currently standing at 4.4. Despite hawkish rhetoric, the BOE recently maintained the policy rate at 3.75% with a 7-2 vote. Nomura believes that due to weakening trends in the UK labor market and lower-than-expected inflation increases, the BOE is not in a hurry to act. Therefore, it has lowered its forecast to no rate hikes this year and expects two rate cuts in the second half of 2027. Fed rhetoric is mild, policy may lag again: The Fed's hawkish rhetoric index rose only slightly to 7.7. Looking back at the previous cycle, when the index reached this level, the Fed delayed its first rate hike by 10 months. Given loose financial conditions under fiscal dominance and the US political cycle, the Fed's policy response this time may again lag. Furthermore, due to the new Fed Chair's aversion to forward guidance, the reference value of related rhetoric indices may decline. Reasons for ECB-BOE divergence: The core reasons for the stark difference between the BOE and ECB are twofold: first, different starting interest rate levels, with the BOE's 3.75% already above neutral, while the ECB's 2.25% is still at or below neutral; second, differences in economic data, with UK inflation lower than expected and the job market weak, while Eurozone inflation is more sticky.

Analysis framework

The report adopts a quantitative text analysis approach to track central bank intentions. The institution introduced Bloomberg's central bank sentiment Natural Language Processing (NLP) model. This model daily quantifies the 'hawkish' or 'dovish' degree of central bank rhetoric by analyzing headlines regarding monetary policy officials' comments on the ECB, BOE, and Fed in Bloomberg News, and compares them with actual policy rate trends. This 'words vs. actions' analytical framework intuitively reveals whether central banks are managing inflation expectations through tough rhetoric (i.e., 'loud bark') or truly taking tightening actions (i.e., 'strong bite').

Methodology notes

• Event Gaming and Behavioral FinanceExpectation Gap/Expectation Management

  Central Bank Expectation Management

  Central banks often guide market inflation expectations by publicly making hawkish or dovish statements (i.e., 'bark'), without necessarily taking immediate actual rate hike or cut actions (i.e., 'bite'). The report analyzes the effectiveness of central bank expectation management and the underlying economic drivers by comparing rhetoric indices with actual interest rates.

  Neutral Rate Analysis

  The neutral rate is the theoretical interest rate level that neither stimulates nor suppresses economic growth. The report points out that the BOE's current rate (3.75%) is considered above the neutral level, while the ECB's rate (2.25%) is still at or below the neutral level. This is the core pricing logic leading to their different policy responses to inflation stickiness.

Key data

• ECB Policy Rate2.25%Raised by 25bp; expected to raise by another 25bp each in Sep 2026, Dec 2026, and Mar 2027
• BOE Policy Rate3.75%Unchanged; expected no rate hikes this year, with two rate cuts in H2 2027
• ECBspeak Hawkish Index20.7Rose the fastest among the three central banks, reaching the highest level since March 2022
• Fedspeak Hawkish Index7.7Rose only mildly, equivalent to the level 10 months before the first rate hike in the previous cycle

Impact & implications

For the market, the significant divergence in monetary policy between Europe and the US means that cross-asset allocation logic needs adjustment. Due to inflation stickiness and the ECB's resolute actions, Eurozone bond yields may find support, and the euro may perform relatively strongly; whereas the UK economy faces pressure from a weakening labor market, and the BOE has low willingness to hike rates, with even expectations of future rate cuts, putting pressure on the pound and UK assets. For the US market, if the Fed again 'lags behind the curve' in fighting inflation, and fiscal dominance maintains loose financial conditions, long-term US inflation risks may rise. Additionally, since the new Fed Chair rejects forward guidance, traditional strategies relying on central bank officials' speeches to predict the Fed's path may fail, and investors need to pay more attention to actual economic data.

Risks

• Continued decline in energy prices may alleviate inflationary pressures in the Eurozone, prompting the ECB to slow the pace of rate hikes
• The new Fed Chair's rejection of forward guidance may cause traditional sentiment models to fail
• US fiscal dominance and the political cycle may lead to abnormally loose financial conditions, exacerbating inflation risks

What to watch

• Whether the ECB fulfills rate hike expectations in September and December at subsequent meetings
• Further evolution of UK labor market and inflation data
• Policy communication style and actual policy response speed after the new Fed Chair takes office
