Definitions
A 'curve flattener' refers to a situation in financial markets where the difference (spread) between long-term and short-term interest rates decreases, causing the yield curve to become less steep or 'flatter.' This can happen when long-term rates fall, short-term rates rise, or both. It is often seen as an indicator of changing economic expectations, such as slowing growth or changing monetary policy.
