US 10-year Treasury yield surpasses 5% amid rising diesel prices

The US 10-year Treasury yield on Monday briefly surpassed 5% for the first time since 2023, influenced by rising diesel prices, which may increase borrowing costs for mortgages and auto loans. By approximately 3:20 p.m. ET, the yield had decreased to 4.967%. The 20-year Treasury yield was reported at 5.376%. The Dow Jones Industrial Average fell by 152 points, or 0.3%, while both the S&P 500 and Nasdaq declined by 0.5%. Concerns regarding increasing energy prices amid the ongoing conflict in Iran and expectations of a potential interest rate hike by the Federal Reserve this week have contributed to a prolonged sell-off in bonds. As traders sold off bonds, Treasury yields, which represent the annual interest paid to investors holding government debt, rose. On Monday, diesel prices reached a record high of $6.23 per gallon, according to AAA, as the conflict in the Middle East continues. Economists have indicated that higher diesel prices could impact the broader economy and exacerbate inflation, as many goods are transported by trucks that rely on diesel fuel. Nic Puckrin, a cross-asset analyst and founder of Coin Bureau, stated that inflation risks stemming from the Strait of Hormuz crisis could diminish the value of bonds, leading investors to seek higher yields. He noted, "The 10-year Treasury yield topping 5%, even if briefly, is more consequential for US households than what the Fed does on Wednesday." He added that if the yield continues to rise, mortgage rates could approach 7%. Treasury Secretary Scott Bessent announced plans to buy back up to $6 billion of government debt, which is three times the usual amount, but investors remain concerned that this measure may not suffice as long as the conflict persists. Treasury yields are currently at levels not seen since 2007, which could further increase mortgage rates and restrict access for potential buyers in a market already under pressure. The US housing market has been largely stagnant for four years due to persistently high interest rates, with homeowners who secured lower rates hesitant to sell. This situation creates a cycle where higher interest rates may deter developers from constructing new properties, thereby limiting supply and negatively affecting the rental market. As of last Friday, the 30-year fixed mortgage rate was 6.76%, according to Freddie Mac. Auto loans, which are closely linked to Treasury yields, could also impact consumers already facing high dealership prices and fuel costs. Higher yields pose a risk to the stock market, as they provide a safer investment alternative, potentially prompting traders to sell stocks and driving down prices. Additionally, Treasury yields influence corporate bonds that businesses utilize for borrowing, which has been a significant factor in stock market gains this year, particularly in the artificial intelligence sector. The Federal Reserve is anticipated to raise interest rates by a quarter point at their September 16 meeting to combat inflation; however, Puckrin noted that this action may not address the fundamental issues driving the bond sell-off. He stated, "Even if the Fed does hike on Wednesday, it’s not in the central bank’s power to fix the underlying problem. The widely expected hike won’t reopen Hormuz or resolve the Middle East situation." He warned that consumers may face increased prices at the pump and grocery store, alongside higher mortgage and borrowing rates, which could lead to higher heating bills for households in the Northeast as winter approaches, potentially resulting in a subdued holiday season.
