The Federal Reserve raised its benchmark interest rate by a quarter of a percentage point on September 16, 2026. But a Fed rate hike and mortgage rates do not have a direct, one-for-one relationship. The headline may sound like mortgage rates automatically increased by the same amount—but that is not how mortgage pricing works.

For homebuyers, the most important takeaway is simple: the Federal Reserve does not directly set mortgage rates. Its decisions can influence the broader interest-rate environment, but mortgage rates respond to several different market forces.

First, what did the Federal Reserve change?

On September 16, the Federal Open Market Committee, or FOMC, increased the target range for the federal funds rate by 0.25 percentage point, moving it from 3.50%–3.75% to 3.75%–4.00%.

The federal funds rate is the rate banks use when lending reserve balances to one another overnight. It can affect borrowing costs throughout the economy, especially short-term and variable-rate products.

In a related but separate action, the Federal Reserve Board approved a 0.25 percentage point increase in the primary credit rate to 4.00%. This is the rate charged to eligible banks that borrow directly from a Federal Reserve Bank through the discount window.

Neither rate is a consumer mortgage rate.

Does the discount rate determine mortgage rates?

No. There is no direct, fixed correlation between the discount rate and the rate offered on a 30-year fixed mortgage.

The discount rate applies to short-term borrowing by banks from the Federal Reserve. A fixed-rate mortgage, by comparison, is a long-term loan whose pricing is influenced by the bond market and the value investors place on mortgage-backed securities.

Mortgage rates are commonly affected by factors such as:

• Inflation and expectations about future inflation
• Yields on longer-term U.S. Treasury securities
• Investor demand for mortgage-backed securities
• The strength of the economy and labor market
• Market expectations for future Federal Reserve decisions
• The borrower’s credit, loan type, down payment, occupancy, and property details

That is why mortgage rates do not always wait for the Fed. Markets often react to economic data and anticipated policy changes before an FOMC meeting takes place. If the Fed’s decision matches what investors already expected, much of the effect may already be reflected in mortgage pricing.

Could mortgage rates still move after the announcement?

Yes. Mortgage rates can move as investors absorb the Fed’s decision, updated economic projections, inflation data, and other news.

But a quarter-point Fed increase does not mean every available mortgage rate will rise by a quarter point. Mortgage rates could rise, remain relatively steady, or decline if the broader market outlook changes.

That makes it helpful to focus on your complete financing plan—not a single headline or a single day’s rate movement.

What can homebuyers do in the short term?

One possible strategy is a temporary rate buydown. A temporary buydown uses funds placed into a dedicated account at closing to reduce the borrower’s monthly principal-and-interest payment during the first one or two years of the loan.

The mortgage itself still has a permanent note rate. The buydown funds cover the difference between the full payment and the temporarily reduced payment during the buydown period.

Depending on the loan program and transaction, those funds may come from a seller, builder, lender, or another eligible source. Contribution limits and program rules apply.

A seller-funded strategy for a rate-sensitive market

When mortgage payments are a major concern for buyers, a seller-funded 2/1 or 1/0 buydown can give real estate agents another way to position a property. Rather than relying only on a price reduction, an agent may present a temporary buydown as a negotiated seller concession designed to reduce the buyer’s principal-and-interest payments during the early years of the loan.

This can be useful when a seller wants to make the home more financially approachable without immediately making a larger price adjustment. For some buyers, an initial payment reduction may feel more meaningful to the monthly budget than a similar amount applied to a modest reduction in purchase price.

A real estate agent can ask the lender to prepare a property-specific illustration showing:

• The estimated cost of the proposed 2/1 or 1/0 buydown
• The buyer’s estimated payment during each buydown year
• The full payment based on the permanent note rate
• How the proposed concession compares with another use of the same funds, such as closing-cost assistance or a price reduction
• Whether the transaction and loan program permit the proposed seller contribution

The concession is negotiated between the parties and affects the seller’s net proceeds. It should not be described as free money or guaranteed savings. The lender must review the structure before it is included in an offer or advertised as a financing feature.

How does a 2/1 buydown work?

• Year 1: The payment is calculated as though the interest rate were 2 percentage points below the note rate.
• Year 2: The payment is calculated as though the interest rate were 1 percentage point below the note rate.
• Year 3 and after: The borrower makes the full payment based on the note rate for the remaining loan term.

For example, if the note rate were 6.75%, the principal-and-interest payment would be calculated using 4.75% in the first year, 5.75% in the second year, and 6.75% beginning in the third year.

This example is for illustration only. It is not a rate quote, offer, or guarantee.

How does a 1/0 buydown work?

• Year 1: The payment is calculated as though the interest rate were 1 percentage point below the note rate.
• Year 2 and after: The borrower makes the full payment based on the note rate.

Using the same hypothetical 6.75% note rate, the first-year principal-and-interest payment would be calculated using 5.75%. The payment would then return to the full 6.75% note-rate payment in the second year.

What a temporary buydown can—and cannot—do

Is a temporary buydown right for every buyer?

No. A temporary buydown can be useful when the lower initial payments fit a buyer’s plans and the full future payment is comfortable. It often deserves the closest look when the seller is willing to fund it through an eligible concession. If the buyer would otherwise pay the buydown cost personally, using those funds toward closing costs, a permanent rate reduction, the down payment, reserves, or another expense may be more valuable.

The right comparison depends on the purchase price, loan program, available concessions, how long the buyer expects to keep the loan, and the household budget.

For Florida homebuyers, the same principle applies: compare the complete financing plan, including the full note-rate payment, taxes, homeowners insurance, mortgage insurance when applicable, and any homeowners association dues.

Questions to ask before choosing a buydown

1. What is my permanent note rate and full monthly payment?
2. What will my payment be during each buydown year?
3. When will the payment increase, and by how much?
4. Who is funding the buydown, and what is the total cost?
5. Can the seller fund it within the contribution limits for my loan program?
6. Would a closing-cost credit or permanent rate reduction be more valuable in my situation?
7. How do taxes, insurance, mortgage insurance, and association dues affect my total payment?
8. Which temporary buydown options are permitted with my loan program?

The bottom line

The Federal Reserve’s latest rate increase matters, but it does not translate directly into the mortgage rate a homebuyer receives.

Mortgage rates are shaped by the broader market and by the details of each borrower’s loan. Even when the rate environment feels uncertain, buyers may have options. A 2/1 or 1/0 temporary buydown can reduce principal-and-interest payments during the first years of the loan and provide additional breathing room while a household settles into homeownership.

The best next step is to review the actual numbers for your purchase, compare available strategies, and make sure the full payment—not only the introductory payment—fits comfortably into your plans.

Frequently asked questions

Does the Fed directly control mortgage rates?

No. The Federal Reserve sets short-term policy rates, but mortgage rates are primarily influenced by the bond market, inflation expectations, mortgage-backed securities, and broader economic conditions.

Will mortgage rates rise by the same amount as the Fed rate hike?

Not necessarily. A quarter-point Fed increase does not automatically produce a quarter-point increase in mortgage rates. Markets may have already anticipated the decision.

What is the difference between the discount rate and a mortgage rate?

The discount rate applies when eligible banks borrow from a Federal Reserve Bank. A mortgage rate is the cost of a consumer home loan and is determined through a different market and underwriting process.

How does a 2/1 temporary buydown work?

A 2/1 buydown reduces the payment as though the rate were two percentage points lower during year one and one percentage point lower during year two. The full note-rate payment begins in year three.

Is a 1/0 or 2/1 buydown better?

It depends on the buyer’s budget, available seller concessions, loan program, expected time in the home, and ability to afford the full future payment. A loan professional can compare the actual costs and payments for both options.

Can a seller pay for a temporary mortgage buydown?

Depending on the loan program and transaction, a seller may be able to fund a temporary buydown through an agreed seller concession. The contribution must be documented and remain within applicable program limits. For example, Fannie Mae applies its interested-party contribution limits when an interested party to the transaction provides the buydown funds.
