ECB's Monetary Policy Strategy Evaluation (2003)

Core Content

In May 2003, the ECB's Governing Council evaluated its monetary policy strategy, which had been in place since October 1998. The evaluation reaffirmed the key elements of the strategy, including the quantitative definition of price stability and the two-pillar framework for assessing risks to price stability.

The strategy defines price stability as a year-on-year increase in the Harmonised Index of Consumer Prices (HICP) for the euro area of below 2%, to be maintained over the medium term. The Council also clarified that it aims to keep inflation rates below but close to 2% in the medium term, to provide a safety margin against deflation and to account for measurement bias in the HICP index.

Main Points

1. Quantitative Definition of Price Stability

• The ECB defines price stability as HICP inflation below 2%.
• This definition ensures transparency and credibility for the public and market participants.
• The medium-term orientation of monetary policy allows for flexibility in responding to economic shocks without focusing on short-term volatility.
• The ECB does not use core inflation as the basis for its quantitative definition due to concerns about transparency and the uniqueness of measurement methods.

2. Clarification of 8 May 2003

• The Governing Council confirmed the definition of price stability and its medium-term focus.
• It emphasized that maintaining inflation close to 2% helps avoid deflationary risks and supports economic stability.
• The decision was in line with public expectations and market understanding, as reflected in long-term inflation expectations.

3. The Two-Pillar Framework

• The framework consists of:
  • Monetary analysis: Assessing medium to long-term inflation trends based on monetary aggregates.
  • Economic analysis: Identifying short to medium-term risks to price stability.
• The two pillars are used to cross-check and validate policy-relevant information.
• The Governing Council decided to no longer review the monetary reference value annually, to reflect its long-term nature.

Key Information

• The HICP is used as the primary price index due to its representativeness, transparency, and timeliness.
• The ECB acknowledges the possibility of measurement bias in the HICP but considers it minor compared to the deflation risk.
• The zero lower bound on nominal interest rates is a key reason for maintaining a positive inflation rate.
• Downward nominal rigidities in prices and wages could be mitigated by flexible compensation mechanisms and productivity growth.
• Inflation differentials across regions are considered a normal feature of a monetary union and are not a target for monetary policy.
• The Balassa-Samuelson hypothesis suggests that inflation differentials may arise from productivity differences, but empirical evidence indicates these are limited and likely to diminish over time.
• The ECB's communication efforts have improved public understanding of its strategy, particularly through the restructured President's Introductory Statement.

Conclusion

The ECB's evaluation of its monetary policy strategy in 2003 reaffirmed its commitment to price stability as a key objective, with a quantitative definition of HICP inflation below 2% and a medium-term focus. The two-pillar framework remains central to the ECB's approach, combining monetary and economic analysis to assess risks to price stability. The decision to no longer review the monetary reference value annually underscores the long-term nature of the ECB's strategy. The clarification of the inflation target below but close to 2% reflects a safety margin against deflation and consideration of measurement bias. The ECB's strategy is seen as successful, with inflation expectations well-anchored and public understanding improved.
