Mortgage rates are once again making headlines across the globe, with significant increases being reported in both the United States and New Zealand. For millions of homebuyers, homeowners, and investors, these shifts are more than just numbers—they directly impact affordability, investment returns, and the long-term financial outlook for households. The recent uptick in rates, driven by a mix of central bank decisions, global economic uncertainty, and even geopolitical conflict, has added fresh urgency to decisions about buying, refinancing, or investing in property.
In the United States, the average interest rate for a 30-year, fixed-rate conforming mortgage loan stood at 6.356% as of March 20, 2026, according to data from Optimal Blue and reported by Fortune. This marks an increase of about 11 basis points from the previous day. The 15-year, fixed-rate conforming mortgage, popular among those aiming to minimize interest payments, also rose to 5.707%, up about 6 basis points. These shifts may seem small at first glance, but the impact on long-term borrowing is substantial. At the current 30-year rate, a $300,000 mortgage would rack up roughly $372,440.16 in interest over its lifetime, while a 15-year loan at current rates would see about $147,178.93 in total interest paid.
The story is similar for larger loans. Jumbo mortgages, which exceed the conforming loan limits set by the Federal Housing Finance Agency, climbed to 6.597%, up 13 basis points. Government-backed loans also saw increases: FHA loans rose to 6.164%, VA loans to 5.999%, and USDA loans to 6.033%. These rates are up between 9 and 15 basis points, reflecting a broader trend across the mortgage landscape.
What’s driving these increases? The Federal Reserve’s recent decision to leave its federal funds rate unchanged at 3.50%–3.75% during its March 17-18 meeting is a key factor. While the Fed’s benchmark rate isn’t the only influence on mortgage rates, it’s a major one. When the federal funds rate climbs, consumer borrowing costs—including mortgages—often follow suit. Conversely, rate cuts tend to bring mortgage rates down. But as Fortune points out, barring a crisis like the COVID-19 pandemic, experts don’t expect to see the ultra-low rates of early 2021 (which hit a record 2.65%) return any time soon.
Other forces are at play as well. According to CBS News, the average rate for a 30-year mortgage was 6.37% as of March 23, 2026, with 15-year rates at 5.87%. These rates translate into higher monthly payments, especially for larger loans. For instance, a $600,000, 30-year mortgage at 6.37% now costs $3,741.26 per month, while a 15-year loan at 5.87% comes in at $5,021.10 per month—excluding taxes and insurance. Just a few weeks earlier, in mid-February, those payments were $3,547.31 and $4,861.21, respectively, at lower rates. That’s an increase of about $195 per month for 30-year terms and $160 for 15-year terms, underscoring how even modest rate hikes can quickly add up.
Despite these increases, the Federal Reserve has kept its rates on hold, creating a climate of uncertainty for borrowers. As CBS News notes, if the Fed continues its pause or signals a possible rate hike, mortgage rates could climb further. This has made locking in a mortgage rate now an attractive option for many, as it provides some protection against future increases. If rates fall before the loan closes, some lenders allow buyers to switch to the lower rate for a fee. If not, refinancing remains an option down the line.
Meanwhile, mortgage applications in the U.S. have taken a hit. The Mortgage Bankers Association reported a 10.9% drop in applications for the week ending March 13, 2026, compared to the previous week. Joel Kan, the MBA’s vice president and deputy chief economist, explained, “Mortgage rates continued to move higher, driven by increasing Treasury yields as the conflict in the Middle East kept oil prices elevated, along with the risk of a broader inflationary shock.” He added, “Rates were around 20 basis points higher than they were two weeks ago and this caused a reversal in refinance activity, particularly for conventional refinance applications, which decreased 27 percent over the week.” Government-backed loans saw mixed results: FHA loans made up 19.4% of total applications, VA loans 16.7%, and USDA loans held steady at 0.4%.
Global events are also influencing mortgage rates, sometimes in unexpected ways. On March 23, 2026, mortgage rates experienced volatility due to bond market fluctuations tied to geopolitical developments involving Iran, as reported by Mortgage News Daily. Early trading suggested rates could spike even higher, but mid-morning headlines about progress in the Iran conflict calmed the markets. The average top-tier 30-year fixed mortgage rate settled back to 6.49% after briefly exceeding 6.5%—a level not seen since early September 2025. However, analysts caution that only a sustained improvement over several days or weeks would signal a true turning point for borrowers hoping for relief.
Across the Pacific, New Zealand is seeing its own wave of rate hikes. As of March 24, 2026, major banks such as ASB and Kiwibank have increased fixed mortgage rates despite the Reserve Bank of New Zealand leaving the official cash rate unchanged, according to 1News, RNZ, and interest.co.nz. Kiwibank raised its one-year fixed rate for borrowers with at least 20% equity from 4.49% to 4.59%, while three-, four-, and five-year rates each rose by 10 basis points to 5.35%, 5.79%, and 5.89%, respectively. ASB lifted its two- and three-year fixed home loan rates by 14 and 20 basis points to 5.09% and 5.39%, though it trimmed its six-month rate by 10 basis points to 4.49%.
At the same time, banks are raising term deposit rates to attract funding. Kiwibank’s one-year deposits climbed by 20 basis points to 3.75%, and three- to five-year terms now range from 4.4% to 4.7%. ASB increased term deposit rates by up to 50 basis points, with its five-year rate reaching 5%. According to interest.co.nz, “5% rates by any bank for any term is a level worth noting” and may indicate that even higher long-term fixed home rates could be on the horizon. These higher deposit rates challenge the net yields on residential rentals, especially as mortgage rates rise and rents soften in some markets.
Adam Boyd, ASB’s executive general manager of personal banking, summed up the situation: “Wholesale interest rates have remained volatile and continue to trend higher. These movements reflect heightened global economic uncertainty and renewed pressures across global markets.” He added, “For savers, the same environment means stronger returns, and it's worth considering how your money could work harder,” but acknowledged that “any increase to home loan rates is significant for households.”
With mortgage rates rising on both sides of the Pacific, borrowers and investors are facing tough choices. Whether it’s locking in a rate now, shopping around for the best deal, or considering alternative investment strategies, the stakes are higher than ever. For many, the decision may come down to timing, risk tolerance, and a careful weighing of the current economic winds. As always, keeping an eye on central bank moves, global events, and market trends will be key to making smart, informed decisions in the months ahead.
