Mortgage Rates Today, Jan 18: 30-Year Refinance Rate Rises by 11 Basis Points

As of today, January 18th, 2026, mortgage refinance rates are moving upwards, with the popular 30-year fixed refinance rate climbing by 11 basis points over the past week to reach 6.62%. This hike signals a shift for homeowners considering tapping into lower rates, making it more important than ever to understand what these numbers mean for your wallet.

Mortgage Rates Today, Jan 18: 30-Year Refinance Rate Rises by 11 Basis Points

The 30-Year Fixed Refinance: Still King, But Pricey-er

The headline news is undoubtedly the 30-year fixed refinance rate, which now stands at 6.62%. According to  Zillow, that's a noticeable jump from last week's average of 6.51%. While a single day's change might seem small, the 11 basis points increase over seven days can add up. Think about it: over the life of a 30-year loan, even a fraction of a percent can mean thousands of dollars more paid in interest.

This particular loan type is the go-to for most homeowners. Why? Because it offers predictability. Your principal and interest payment stays the same for the entire 30 years. This kind of stability is invaluable, especially in uncertain economic times. However, with the rate nudging higher, the immediate savings you might have hoped for by refinancing could be less significant, or even non-existent, depending on your current mortgage.

15-Year Fixed Refinance: A Faster Path, A Slightly Higher Price Tag

If you're someone who likes to pay off your mortgage faster and reduce the total interest paid over time, the 15-year fixed refinance rate is probably more your speed. This rate also saw an increase, moving from 5.60% to 5.67%, a rise of 7 basis points.

While 15-year loans typically come with lower interest rates than their 30-year counterparts, this recent uptick has narrowed that gap a bit. For those who can comfortably afford the higher monthly payments of a 15-year loan, it's still a fantastic way to build equity rapidly and save substantially on interest in the long run. But as the cost goes up, the decision to refinance becomes a more detailed calculation, weighing the immediate payment increase against long-term savings.

5-Year ARM Refinance: The Volatility Factor Gets Costlier

Adjustable-rate mortgages (ARMs), specifically the 5-year ARM refinance rate, have seen a more dramatic shift. This rate climbed by 10 basis points, moving from 7.09% to 7.19%.

ARMs are often attractive because they usually start with a lower interest rate than fixed-rate mortgages. This can mean lower initial monthly payments, which appeals to many homeowners. However, the entire point of an ARM is that the rate can change, and often does, after the initial fixed period. Seeing the 5-year ARM rate now sitting higher than the 30-year fixed rate is a significant signal. It suggests that the market might be bracing for potential future rate increases, making the certainty of a fixed rate increasingly appealing, even at a slightly higher initial advertised rate. For me, this is a key indicator that the allure of the lower initial ARM payment might be outweighed by the risk of much higher payments down the road.

Key Takeaways from the Numbers:

• The 30-year fixed refinance rate took the biggest step up, showing a clear upward trend.
• The 15-year fixed refinance rate climbed too, but this rise puts it closer in competition with the 30-year option, making the decision between them more nuanced.
• The 5-year ARM refinance rate experienced a significant jump, making fixed-rate mortgages look more attractive by comparison for many homeowners.

What These Rate Moves Mean for You

So, what does this all boil down to for us homeowners?

• Refinancing Just Got More Expensive: Even small increases in basis points can translate to more money out of your pocket over many years. It means that the “break-even” point for refinancing – the point where your savings from lower payments cover the costs of refinancing – might take longer to reach now.
• Timing is Everything (But Also Impossible to Predict): If you were on the fence about refinancing, this upward movement might push you to act sooner rather than later. However, trying to perfectly time the market is like trying to catch lightning in a bottle. It's often better to focus on whether refinancing makes sense for your financial goals right now, not just because rates are at their absolute lowest.
• Choosing the Right Loan Type Matters More Than Ever: Fixed-rate mortgages offer peace of mind, especially when rates are trending up. ARMs might still be an option for some, but the recent increases highlight the inherent risk. It's a trade-off between lower initial payments and future uncertainty.

Looking Ahead: What Experts Are Saying About 2026 Rates

It's always wise to look a bit into the future. The mortgage market is heavily influenced by economic factors and Federal Reserve policies.

I recall the news about a significant boost in refinance demand, soaring an impressive 128% compared to the previous year. This surge was largely seen as a brief “refinance window,” attracting homeowners who originally locked in rates above 7% back in 2023 or 2024. There was also chatter about President Trump's directive to Fannie Mae and Freddie Mac to buy $200 billion in mortgage bonds, a move intended to ease borrowing costs.

Despite some rate cuts by the Federal Reserve in late 2025, mortgage rates have been stubbornly hovering in the 6% range. The general expectation heading into the end of January is that the Fed will likely keep rates steady at their upcoming meeting.

When it comes to the rest of 2026, the consensus among many housing economists is that rates will likely stay within the 6% to 7% range. Fannie Mae, for instance, predicts a gradual decrease, but they anticipate rates will remain at or just above 6% for the bulk of the year.

As for a good rule of thumb for when to refinance, experts often suggest looking to refinance when market rates are at least 1% to 2% lower than your current rate. This helps ensure that your savings from a lower monthly payment will eventually offset the closing costs, which typically fall between 2% and 5% of your loan amount.

The Bottom Line

As we wrap up January 18th, 2026, the trend for refinance rates is clearly pointing upwards. The 30-year fixed, 15-year fixed, and even the 5-year ARM all saw increases over the past week. For homeowners, this means that the cost of borrowing is rising, and smart financial planning is more critical than ever. Whether you're eyeing a refinance to lower your monthly bills, consolidate debt, or access your home's equity, keeping a close eye on these rate movements and understanding how they fit into your personal financial picture is absolutely key to making the right call.
