Rising interest rates affect far more than mortgages. Many banks are also increasing rates on their savings accounts, meaning you could earn a ton of money by switching banks.
Customers with only $1000 will make an extra $30 per year when they move their money from an account offering .01% APY to one offering 3%, not including interest from additional contributions.
Those with more in savings have even more to gain. A $10,000 initial investment will earn $300 over a year, while a $50,000 savings account will earn $1500.
