We have heard and read a lot about central banks increasing interest rates in the face of inflationary episodes as a preventive policy or to contain existing inflation.
Why and how a hike in interest rates leads to a decline in inflation rate is a theoretical discussion that has a long history (perhaps more than 100 years); it has been discussed in detail in monetary economics.
This writing is not about theoretical, academic arguments. However, it is important to know that introducing the short-term interest rate in the money market is currently the most effective policy used by central banks to curtail inflation.
