Abstract
We construct monetary policy indicators from high-frequency asset price changes following policy announcements, emphasising the concentration of asset price responses along specific dimensions and their leptokurtic distribution. Traditionally, these dimensions are identified by rotating principal components based on economic assumptions that overlook information in excess kurtosis. We employ Varimax rotation, leveraging excess kurtosis without using economic restrictions. Within a set of euro-area risk-free assets Varimax validates policy news along dimensions previously derived from structural identification approaches and rejects evidence of macroinformation shocks. Yet, once adding risky assets Varimax identifies only one risk-free factor in medium- to long-term yields and instead points to additional risk-shift factors.

Abstract
Financial markets and analysts significantly underestimated the pace and size of the recent increases in the key ECB interest rates. This box measures the size and dynamics of policy expectation errors. Based on information from the ECB’s Survey of Monetary Analysts, it suggests that these expectation errors were driven mainly by revisions to macroeconomic expectations, indicating that analysts perceived a broadly consistent policy reaction to macroeconomic developments.
