Mortgage rates are on the rise again, sending ripples through the U.S. housing market and prompting both homebuyers and investors to rethink their financing strategies. As of March 19, 2026, the 30-year fixed mortgage rate has climbed to 6.22%, marking a three-month high not seen since December 2025, according to data reported by MarketWatch and Fortune. The 10-year Treasury yield, a key benchmark for mortgage rates, has also risen to 4.3%, reflecting broader market unease and adding to the pressure faced by prospective homebuyers.
For many Americans, these higher borrowing costs are making homeownership less affordable. The average rate had dipped as low as 5.98% in late February before beginning a steady march upward through March. But while the spring housing market feels the squeeze, a select group of companies and certain homebuyers are finding ways to benefit from this high-rate environment.
One of the most notable shifts is the growing popularity of adjustable-rate mortgages (ARMs), particularly among affluent buyers and in high-cost markets. According to MarketWatch, by December 2025, nearly half of all mortgage originations exceeding $1 million were ARMs. That’s a dramatic increase, especially considering that approximately 92% of all U.S. mortgage holders still opt for fixed-rate loans, as Fortune notes. The reason? The initial rates on ARMs are typically lower than those for 30-year fixed mortgages, offering significant savings in the early years of the loan.
“What’s different now is that we’re seeing real savings on five-, seven- and even 10-year ARMs,” said Scott Griffin, a Los Angeles-based mortgage broker, to MarketWatch. “All three borrowers chose adjustable-rate mortgages because the monthly savings compared to a 30-year fixed rate were simply too good to ignore.” For context, the 5/1 ARM is currently hovering around 5.3%, compared to the 6.1% range for 30-year fixed rates. On a $1 million loan, that difference can save a buyer about $500 each month.
This trend is especially pronounced in expensive markets. In California, 31% of mortgage originations in 2025 were ARMs, followed by 28% in Washington, D.C., and about 24% in Massachusetts. “ARM activity tends to be higher in more expensive markets,” MarketWatch reports, as borrowers look for any edge to make monthly payments more manageable in the face of stubbornly high home prices.
But it’s not just individual buyers making moves. Several companies are strategically positioned to benefit from the current rate climate. Rocket Companies, for instance, has become a dominant force following its $14.2 billion acquisition of Mr. Cooper in late 2025. With a combined servicing portfolio of $2.1 trillion in unpaid principal balance—representing about one in every six U.S. mortgages—Rocket is now able to generate roughly $5 billion in annualized recurring cash flow. This is thanks to a “natural hedge”: when rates are high, homeowners are less likely to refinance, keeping loans on Rocket’s books longer and maximizing servicing income.
“This is the power of an integrated homeownership ecosystem—massive top of funnel, scaled origination-servicing recapture, expansive distribution for industry professionals and a technologically advanced foundation for infinite capacity—built for the AI era,” said Rocket CEO Varun Krishna, as quoted by MarketWatch.
Big banks like JPMorgan Chase and Wells Fargo are also reaping rewards. Both institutions benefit from higher net interest income (NII) when rates climb, as they pay depositors less than they earn on loans and securities. Wells Fargo, for example, guided for approximately $50 billion in NII (excluding markets) in 2026, up from $46.7 billion the previous year. JPMorgan reported a 7% increase in NII in Q4 2025, driven by higher deposit balances. Notably, the Federal Reserve recently removed Wells Fargo’s asset cap, giving the bank new room to grow. “We are excited to now compete on a level playing field and are able to dedicate even more resources to growth with the ability to grow our balance sheet,” said Wells Fargo CEO Charlie Scharf.
Meanwhile, apartment real estate investment trusts (REITs) like AvalonBay Communities and Essex Property Trust are seeing indirect benefits. When homebuying becomes too expensive, more people choose to rent, boosting demand for apartments. AvalonBay’s CEO noted, “It is over $2,000 per month more expensive to own a home” in their core markets at current rates and prices. Essex reported a same-property revenue growth of 3.8% year-over-year in Q4 2025 with financial occupancy at 96.3%. Supply in Essex’s West Coast markets is declining, with available units dropping from 52,400 in 2025 to 42,300 in 2026. AvalonBay’s same-store residential occupancy stands at 95.8%, and it has guided for 2026 core funds from operations of $11.00 to $11.50 per share.
But what about the average homebuyer? For those considering ARMs, there are some clear scenarios where these loans make sense. According to Fortune and MarketWatch, ARMs are attractive for buyers who expect to move, refinance, or upgrade homes before the initial fixed-rate period ends—often five to seven years. Real estate investors also favor ARMs, as they can capitalize on lower initial rates and potentially sell or rent out properties before adjustments kick in. Additionally, buyers during periods of high interest rates may turn to ARMs for the chance at lower payments, at least in the short term.
ARMs typically start with a fixed interest rate for a set duration—three, five, seven, or ten years—before entering an adjustment period. The new rate is determined by benchmark rates like the Secured Overnight Financing Rate (SOFR), lender margins (usually between 2% and 3.5%), and rate caps that limit how much the rate can jump. Common ARM structures include the 5/1 ARM (five years fixed, then annual adjustments), 7/6 ARM (seven years fixed, then adjustments every six months), and 10/6 ARM (ten years fixed, then adjustments every six months).
Of course, ARMs aren’t for everyone. “Some homeowners sleep better at night knowing their rate will never change—and for those borrowers, a 30-year fixed rate is still the best choice,” said Griffin. The main drawback of ARMs is the risk that monthly payments may rise after the fixed period ends, making budgeting less predictable. However, today’s ARMs are more tightly regulated than those that contributed to the 2008 financial crisis, with caps designed to protect borrowers from extreme payment shocks.
For those who choose an ARM but later decide to stay in their home longer, refinancing to a fixed-rate mortgage remains an option. As Fortune points out, the process is similar to refinancing any other mortgage: shop for rates, provide documentation, close on the new loan, and pay off the old one. Many Millennials and Gen Z homeowners, for instance, are finding themselves staying longer in their starter homes and may need to pivot their financing strategy as circumstances change.
Ultimately, the recent surge in mortgage rates is reshaping the housing market, creating winners and losers and forcing buyers to weigh their options more carefully than ever. Whether choosing a fixed-rate mortgage for peace of mind or an ARM for upfront savings, today’s borrowers are navigating a landscape where flexibility, strategy, and a clear understanding of the risks and rewards are more important than ever.
As the market continues to evolve, industry watchers recommend keeping an eye on the 10-year Treasury yield and prediction markets for clues about where rates may head next. For now, the gap between fixed and adjustable rates, combined with climbing home prices, is making ARMs an increasingly popular—if nuanced—tool for those looking to make the numbers work.
