Real rates and policy

The real rate roughly describes what remains of a nominal rate after inflation. Policy rates are quoted in nominal terms; purchasing power is the real view.

In more detail

Approximation: real rate ≈ nominal rate minus inflation. The Bundesbank publishes real rates on bank deposits. ECB policy rates are a different series. Both are statistics and a description of policy, not a trading signal.

Background

Exactly: (1 + nominal rate) / (1 + inflation rate) − 1. Expected inflation gives a forward-looking real rate; measured inflation a backward-looking one. Finmon uses Bundesbank and ECB sources only for orientation. This module recommends no position and contains no forecast.

An example

A 2% deposit rate and 3% inflation give about −1% real before tax. That is a purchasing-power model, not a product comparison and not a buy order.

A common misconception

The real rate tells me what to buy or sell.

The real rate describes the purchasing power of interest. Bundesbank and ECB series are not trading instructions.
