What is the Cost of Funds Index COFI and how does it affect mortgages?
I love talking about mortgage rates and indexes because they play such a big role in home buying decisions. If you're looking into adjustable-rate mortgages (ARMs), you might have come across COFI - a unique index that's particularly popular in western states. Let me break this down for you in a way that makes sense.
Cost of Funds Index (COFI): The Cost of Funds Index (COFI) is a measure that tracks the average interest rate that banks in the Western United States pay for their borrowed money and customer deposits. This rate is commonly used to adjust interest rates on some adjustable-rate mortgages (ARMs), particularly in the western states.
Definition and Basic Concepts
COFI isn't just another random number - it's calculated based on real costs that banks face. Think of it as a reflection of what banks pay to get the money they lend to you. The index looks at two main things: how much banks pay to borrow money themselves, and what interest rates they're paying their customers on deposits.
What makes COFI special is its regional focus on the Western United States. This regional aspect makes it particularly relevant if you're house hunting in states like California, Oregon, or Washington.
How COFI Works in Practice
The calculation of COFI happens monthly, with various western banks reporting their costs. The Federal Home Loan Bank of San Francisco crunches these numbers and releases the index around the end of each month. This process creates a reliable snapshot of banking costs in the western region.
COFI vs. Other Popular Mortgage Indexes
You might be wondering how COFI stacks up against other indexes. Unlike LIBOR (which is being phased out) or the Prime Rate, COFI tends to move more slowly and steadily. This can be good news for your monthly payments, as they might not jump around as much as with other indexes.
Impact on Adjustable Rate Mortgages
If you have a COFI-based ARM, here's what you need to know about rate adjustments:
Your rate typically adjusts once every month or year
Your actual rate will be COFI plus a margin (set by your lender)
Rate caps still protect you from extreme changes
Historical Performance
Looking back, COFI has shown itself to be relatively stable compared to other indexes. This stability comes from its connection to actual bank costs rather than market speculation or federal policy decisions alone.
Advantages and Disadvantages of COFI-Based Mortgages
Benefits:
More stable than many other indexes
Strong regional connection in western states
Usually changes are gradual rather than sudden
Drawbacks:
Mainly useful in western states
Can be harder to understand than simpler indexes
Rate changes might lag behind market trends
Common Questions About COFI
How often do rates change?
COFI rates update monthly, but your mortgage might adjust less frequently depending on your terms.
What about monthly payments?
Your payments might change each time your rate adjusts, but the changes are often more gradual than with other indexes.
Should I refinance my COFI ARM?
This depends on your current rate, market conditions, and personal financial goals.
Future of COFI in Mortgage Lending
The mortgage market keeps changing, but COFI maintains its place as a reliable index, especially in the western United States. While new alternatives might emerge, COFI's stability and regional focus keep it relevant for many borrowers.
