When you’re shopping for a mortgage, one of the most important factors is the interest rate. Many potential homebuyers wonder why mortgage rates seem to change daily, even hourly, and how these fluctuations are determined. To understand why interest rates vary, it’s essential to know about mortgage-backed securities (MBS) and their impact on mortgage interest rates. Let’s dive in!
What Are Mortgage-Backed Securities?
Mortgage-backed securities (MBS) are bonds made up of bundled home loans that are sold to investors. Think of MBS as a pool of mortgages combined together to form an investment product that investors can buy and sell. When investors purchase MBS, they essentially “own” the income streams (the monthly mortgage payments) from those loans.
The Connection Between MBS and Mortgage Rates
The rates on mortgage loans are closely tied to the performance of MBS. Here’s how it works:
- Demand and Supply for MBS: Just like any other investment, mortgage-backed securities are influenced by market demand and supply. When MBS are in high demand, investors are willing to accept lower returns (yields) since MBS are a relatively safe investment, backed by mortgages. In response, mortgage rates for consumers may decrease, as lenders can pass along these lower costs.
- Bond Market Influence: Mortgage rates don’t directly follow the Federal Reserve’s rate changes. Instead, they are more closely linked to the bond market, specifically the yields on 10-year Treasury bonds. The 10-year Treasury yield acts as a benchmark; when it rises, MBS yields tend to rise, leading to higher mortgage rates, and vice versa.
- Economic Data and Market Sentiment: Investors track economic data such as employment reports, inflation numbers, and consumer spending patterns. Strong economic data can increase fears of inflation, leading investors to demand higher returns for MBS. As a result, mortgage rates may rise. Conversely, if economic data is weak or suggests a potential downturn, demand for safer investments like MBS may increase, driving yields and mortgage rates down.
How Mortgage Rates Are Priced Daily
Mortgage lenders determine daily mortgage rates by observing the market conditions for MBS and considering:
- Price Movements in MBS: Mortgage lenders look at the price of MBS in the market. When MBS prices go up, yields go down, which can lead to lower mortgage rates for borrowers.
- Market Volatility: Any significant swings in the financial markets can lead to quick adjustments in mortgage rates. Economic events, geopolitical news, and announcements from the Federal Reserve can create volatility, causing rates to change frequently throughout the day.
Factors You Can Control
While mortgage rates are largely driven by MBS market fluctuations, there are some elements that you, as a borrower, can control:
- Credit Score: Higher credit scores typically qualify you for lower interest rates, as lenders see you as a lower risk.
- Loan-to-Value Ratio (LTV): The size of your down payment can influence your rate. A higher down payment (or lower LTV) generally results in a better rate.
- Loan Type and Term: Different loan types (e.g., fixed-rate vs. adjustable-rate) and terms (e.g., 15-year vs. 30-year) come with varying rates. Work with your lender to determine the best fit for your needs.
How to Stay Informed
Mortgage rates change based on complex factors, but as a buyer, you don’t have to navigate this alone. Working with a mortgage professional can help you understand market trends, lock in a rate when the timing is favorable, and choose a loan that meets your long-term goals.
