Turmoil in the bond market, driven by the conflict with Iran, is pushing US mortgage rates upward and posing a risk of increasing the cost of home purchases. The average 30-year fixed-rate mortgage increased to 6.51% this week, marking the highest level since August of the previous year, as reported. It marked the most significant weekly rise in mortgage rates since April 2025, a period characterised by comparable strain in the bond market following President Donald Trump’s initial announcement of extensive, historic tariff hikes affecting nearly all nations. Mortgage rates exhibit a correlation with the US 10-year Treasury yield, which is intricately linked to inflation expectations. The yield, which moves inversely to bond prices, surged this week, reaching its highest level in over a year as investors became increasingly concerned that escalating oil prices and the conflict in Iran could lead to sustained inflationary pressures. Prices increased by 3.8% in April, marking the highest level since May 2023, as indicated by the most recent Consumer Price Index data published last week. For the first time in three years, Americans’ wages failed to exceed inflation, as indicated by the report.
Prior to the onset of the Iran war, average mortgage rates experienced a temporary decline, falling below 6% for the first time in over three years. Home buyers who secured mortgages in the past may experience considerable savings when compared to those securing loans in the current market. Consider a residence valued at $450,000, for instance. At a 30-year fixed mortgage rate of 5.98% — the average at the end of February — monthly principal and interest payments would amount to approximately $2,154, given a 20% down payment. At the average rate observed last week, those payments would increase to approximately $2,278 per month. That results in an additional $1,488 annually, totalling over $44,640 throughout the duration of the loan. Mortgage rates remain lower than they were at the same time last year. In mid-May of the previous year, the average rate for a 30-year fixed mortgage stood at 6.86%.
However, rates have not decreased to the extent that some analysts had originally anticipated following the Federal Reserve’s three interest rate cuts during that period. Higher borrowing rates and economic anxiety stemming from the Middle East conflict are beginning to influence the housing market, with initial indicators pointing to a sluggish commencement of the spring homebuying season, a period traditionally characterised by increased sales activity. According to April data, mortgage applications for new home purchases have experienced a decline of 2.4% compared to the same period last year. In comparison to March 2026, applications experienced a decline of 10%. Fewer applications are resulting in a decline in home sales. Existing home sales increased by a modest 0.2% from March to April, following a decline of 3.6% in the preceding month, as reported. Alongside elevated mortgage rates, national home prices have remained close to historical highs.
The median existing home sales price reached $417,700 in April, marking the 34th consecutive month of year-over-year price increases, as reported. “There are two barriers to home ownership that are pertinent at this moment. One factor is elevated mortgage rates; the other is prevailing uncertainty. When you buy a house, you’re cutting the biggest cheque you’ve ever cut in your life’, stated Brad Case. “You have to have a firm foundation to make this big decision, and that’s what people are missing as a result of the moves in rates since the beginning of March, regardless of whether they’re up or down,” he added.
