Central banks reply to inflation by setting rates of interest so as to obtain home value stability. Sometimes, financial shocks are international in nature and so financial coverage can transfer in tandem the world over. However how frequent have directional adjustments in financial coverage been the world over over latest many years?
To reply this, we developed a financial coverage diffusion index (MPDI) as an instance the breadth of financial coverage adjustments. The diffusion index is calculated as = 1* per cent of central banks rising rates of interest + 0.5* per cent leaving charges unchanged + 0* per cent lowering charges.
A studying above/under 50 signifies that extra central banks have elevated/lowered rates of interest relative to the earlier quarter, than the reverse. The MPDI doesn’t embody adjustments in different financial coverage instruments, corresponding to asset purchases.

The worldwide MPDI highlights two durations of broad coverage easing over latest many years (Chart 1). In 2009, a median of 25 out of 39 main central banks lower charges every quarter in response to the International Monetary Disaster. In 2020, a broadly comparable proportion lower charges to assist development and inflation in response to Covid-19.
Extra just lately, the MPDI underscores the breadth in coverage tightening in opposition to elevated inflationary pressures. In 2022 Q2, slightly below 30 main central banks raised charges, the best proportion because the Index started.
