Inter-meeting speeches drive long-term euro market rate moves
Public speeches and interviews between rate-setting meetings move financial markets with the same magnitude as formal policy decisions, according to new European Central Bank research. The study tracks 5,000 communication events between 1999 and 2024.
Cumulative weight on equity and swap rates
Analysis of 304 formal monetary policy announcements and around 5,000 inter-meeting communication events from 1999 to 2024 reveals that informal remarks regularly shift asset prices.
While 45 percent of formal announcements sparked a measurable reaction, the sheer volume of speeches created a larger cumulative effect.
Inter-meeting events moved the Euro Stoxx 50 index by 273 percentage points across more than 300 distinct episodes, compared with 98 percentage points across 117 formal announcements.
For the two-year overnight index swap rate, cumulative moves reached 681 basis points for informal communications and 718 basis points for formal decisions, with informal events exerting double the impact at longer maturities.
Signaling rate paths and transmission
Average market impacts on two-year swap rates reached 5.13 basis points for formal decisions, 2.56 basis points for presidential speeches, and 2.42 basis points for remarks by German, French, Spanish, and Italian central bank governors.
Rate adjustments also show asymmetry: communication intensifies more before rate increases than before cuts.
Integrating inter-meeting surprises into Bayesian vector autoregression models delivers tighter confidence bands for unemployment and inflation transmission.
Noise for traders, precision for modelers
The findings validate what bond desks already practice by treating inter-meeting speeches as de facto policy adjustments.
However, elevating hundreds of casual remarks into macroeconomic shocks risks mistaking political noise for coordinated strategy.
The model gains empirical precision, but market participants gain little clarity.
