Savings interest rates vs mortgage rates

The interest rate for savings account is determined by Federal Fund rate.  Fed Reserve Open Market Committee raises and cuts the Federal Fund rate which banks charge each other to borrow money.  The mortgage rates are based on US treasury 10 years bond rate.  One is a short term rate and the other is a long term rate.  At this point, Fed Fund rate is at 1% and the 10-year bond rate is aroun 2.5%.  So your savings account interest rate definitely will be lower than 1% and your mortgage will be higher than 2.5%.
