# About interest rate management

In this guide, you will find information on how to add currency-based interest rates to the Tuum system. The base rate control is a part of the currency API functionality. Therefore, this functionality has a cross-product usage. Currently, this feature is available for the loan products.

With the example of the loans module, we will show how you can configure a new loan product with a floating interest rate and apply reference rates as a base rate or interest rate cap.

{% hint style="info" %}
In the current section, the interest rate and rate are used as synonyms.
