Ever wonder how the economy goes ’round? Or how inflation is controlled and recessions are avoided?
A lot of it has to do with the Federal Reserve and its tight control of the money supply. Let’s take a closer look to better understand how it all works. And how it affects mortgage rates.
(Latest rate movement 3/15/17, last updated 3/15/17)
Discount Rate (Currently 1.50%)
The “discount rate” is the interest rate the Federal Reserve sets and offers to member banks and thrifts that need to borrow money in order to prevent their reserves from dipping below the legally required minimum.
This situation can arise if a bank lends too much and/or has too many withdrawals on a given day. Money is borrowed overnight via the “discount window.”
As a rule of thumb, the higher the discount rate, the higher mortgage interest rates will be. The two tend to correlate over time, though not as strongly as the 10-year bond yield due to its longer maturity.
When the discount rate goes up, the prime rate goes up as well, which can slow the demand for new loans and cool the housing market.
The opposite is also true. If the Fed lowers the discount rate, the prime rate will come down and mortgage interest rates may dip to more favorable levels.
This can boost a slumping housing market, though the decision to purchase a home doesn’t always come down to the level of interest rates, as some buyers purchase with cash, and a stronger economy leads to higher home prices.
Prime Rate (Currently 4.00%)
The “prime rate” is the interest rate offered by commercial banks to its most valued corporate customers. But in reality, it just serves as a benchmark for lending rates.
The prime rate always adjusts based on how the Fed moves the discount rate. If the discount rate is increased, the prime rate will follow suit. And vice versa.
The prime rate is the basis for certain home loan programs, including widely issued HELOCs (Home Equity Line of Credit), which many banks offer to homeowners at prime plus “X” amount, prime minus “X” amount, or simply prime plus zero.
So HELOCs are essentially adjustable-rate mortgages because they’re variable based on the Fed’s action. Of course, there have been and will be long periods where the prime rate doesn’t change much or at all.
Federal Funds Rate (Currently 0.75% – 1.00%)
The “federal funds rate” is the interest rate banks charge one another for overnight use of excess reserves. Put simply, banks can avoid borrowing directly from the Federal Reserve (via the discount window) by borrowing from one another instead.
The Federal Reserve doesn’t actually set the federal funds rate, but rather sets a “target rate” and works to keep it in a given range by buying or selling government bonds.
The Fed uses the federal funds rate to control the supply of available funds, essentially controlling inflation. If the federal funds rate is low, banks will be keen to borrow from one another, using the reserves to grant more loans, which in turn feeds the economy.
If the Fed feels the need to slow things down, they will simply raise the target for the federal funds rate, which will curtail borrowing among banks and reduce the amount of new loans issued to businesses and consumers.
Keep in mind that these key rates are just one of the many factors that determine the direction of mortgage rates. So don’t assume mortgage rates will be lower (or higher) just because these rates are.
Conversely, if you’ve got an ARM it could push the related mortgage index higher or lower depending upon the action taken, which would alter your fully-indexed rate and corresponding monthly payment.
If you’re shopping mortgage rates, Fed action can make a meaningful impact, so always pay attention to what’s going on in the economy!
