# Savings Module

The Reservoir savings product offers users the ability to exchange rUSD for a variable rate yield-bearing token srUSD. Governance will periodically set an interest rate based on market conditions, changing the rate of srUSD's price appreciation in rUSD terms. When issued, the user burns their rUSD and mints srUSD at the current price and can be sure the price will either be the same or higher upon redemption when they burn their srUSD for rUSD.
