Mortgage rates climbed across the board during the week of March 7, 2026, adding pressure on homeowners who have been waiting for a better moment to refinance. All three major loan types tracked by Wirly moved higher compared to the prior week, continuing a pattern that borrowers and housing watchers will want to follow closely. Understanding what is driving these moves can help you make a more informed decision about your home loan.
Rates as of March 26, 2026, based on data from the Federal Reserve Economic Data (FRED). Previous week data is from March 19, 2026. Wirly is an educational comparison platform and is not a lender or mortgage broker.
This Week’s Rates
Here is a snapshot of where mortgage rates stood for the week ending March 7, 2026:
- 30-Year Fixed: 6.38% – up 0.16% from the previous week
- 15-Year Fixed: 5.75% – up 0.21% from the previous week
- 5/1 ARM: 6.06% – up 0.11% from the previous week
The 15-year fixed rate saw the largest single-week jump of the three, rising 0.21 percentage points. That is a notable move in a short period of time. The 30-year fixed rate, which is the most commonly used loan type for home purchases and refinances, climbed to 6.38%. The 5/1 adjustable-rate mortgage, which offers a fixed rate for the first five years before adjusting, also ticked up, though by a slightly smaller margin of 0.11%.
Even small weekly increases in rates can affect monthly payments in a meaningful way, especially on larger loan balances. Homeowners considering a refinance may want to use the Wirly refinance calculator to see how these rates could affect their specific situation.
Why Rates Moved
To understand why mortgage rates moved higher, it helps to look at two key economic benchmarks: the Federal Funds Rate and the 10-Year Treasury yield.
The Federal Funds Rate currently sits at 3.64%. This is the interest rate at which banks lend money to each other overnight, and it is set by the Federal Reserve. While the Fed does not directly control mortgage rates, its rate decisions influence borrowing costs throughout the broader economy. A Fed Funds Rate of 3.64% signals that policymakers have already pulled rates down from higher levels seen in recent years, but have not moved aggressively to cut further.
Perhaps more directly tied to mortgage rates is the 10-Year Treasury yield, which stands at 4.42%. Lenders closely watch the 10-Year Treasury because it tends to move in the same direction as long-term mortgage rates. When investors demand higher returns on Treasury bonds, mortgage rates typically follow. With the 10-Year yield sitting at 4.42%, it is helping to explain why the 30-year fixed rate remains elevated above 6%.
The spread between the 10-Year Treasury yield (4.42%) and the 30-year fixed mortgage rate (6.38%) is approximately 1.96 percentage points. Historically, this spread has tended to be in the range of 1.5 to 2 percentage points, so the current gap is on the wider side but not dramatically out of range. A wider spread can sometimes indicate that lenders are building in more caution or that mortgage-backed securities markets are pricing in uncertainty.
What This Means for Refinancers
If you are a homeowner thinking about refinancing, the current rate environment requires some careful thought. The 30-year fixed rate at 6.38% may still represent a meaningful opportunity for some borrowers, particularly those who took out loans at higher rates in 2023 or early 2024, when rates climbed above 7% in many cases.
Here are a few practical considerations:
- Break-even timeline: Refinancing involves closing costs, which typically need to be recouped before you actually save money. The lower your new rate compared to your old rate, the faster you could break even. A smaller rate reduction may take longer to pay off.
- 15-year vs. 30-year: The 15-year fixed rate at 5.75% is notably lower than the 30-year at 6.38%. Borrowers who can afford higher monthly payments may save significantly on interest over the life of the loan by choosing a shorter term.
- Adjustable-rate options: The 5/1 ARM at 6.06% sits between the 15-year and 30-year fixed rates this week. If you plan to sell or refinance again within five years, an ARM could be worth exploring, though it does carry the risk of rate increases after the initial fixed period ends.
- Your current rate matters most: The value of refinancing depends heavily on what rate you have right now. If your existing mortgage is already below 6%, today’s rates may not offer a clear financial benefit.

Should You Lock or Wait?
This is one of the most common questions homeowners ask, and the honest answer is that no one can say with certainty where rates are headed. What we can do is weigh the current data and consider the possibilities.
On one hand, rates have moved higher three consecutive data points across all loan types this week. If economic data continues to come in strong or if inflation remains stubborn, rates could stay elevated or move higher. In that scenario, waiting might mean refinancing at a less favorable rate later.
On the other hand, if economic conditions soften or if the Federal Reserve signals further rate cuts, long-term mortgage rates could ease. The Fed Funds Rate at 3.64% suggests there may be room for future adjustments, but the timing and size of any such moves are not guaranteed.
A few questions worth asking yourself before deciding:
- How long do you plan to stay in your home? A longer time horizon generally makes locking in a rate more worthwhile.
- How much could you save each month at today’s rate versus your current rate?
- Are you financially prepared to handle the closing costs of a refinance now?
- What is your tolerance for uncertainty if rates move in either direction?
If the current rate offers a meaningful monthly savings and your break-even period fits your plans, locking sooner rather than later may make sense. If the savings are modest, waiting to see if rates ease could also be a reasonable approach.
Bottom Line
Mortgage rates rose across all loan types during the week of March 7, 2026. The 30-year fixed landed at 6.38%, the 15-year fixed reached 5.75%, and the 5/1 ARM came in at 6.06%. These moves were driven in part by a 10-Year Treasury yield of 4.42%, which tends to pull long-term mortgage rates along with it. The Fed Funds Rate of 3.64% suggests monetary policy has shifted somewhat, but that has not yet translated into significantly lower mortgage rates.
For homeowners considering a refinance, the decision comes down to your personal numbers – your current rate, your remaining loan balance, how long you plan to stay in your home, and how quickly you could recover closing costs. There is no universal right answer.
