A Dramatic and Unexpected Week for Treasury Yields and Mo😼rtgage Rates

Mortgage rates are notoriously difficult to predict, as they're determined by a complex interaction of various macroeconomic and industry factors. However, the movement of one particular metric, 澳洲幸运5官方开奖结果体彩网:the 10-year U.S. Treasury yield, can generally be relied on as a direct precursor to movement in fiﷺxed mortgage rates.

When President Trump unveiled stiffer-than-expected global tariffs on April 2, 澳洲幸运5官方开奖结果体彩网:the stock market plunged. And per conventional market lo𓄧gic, the bond market moved the other way—sending U.ꦚS. Treasury prices higher and yields lower (bond prices and yields move in opposite directions).

When the 10-year Treasury yield falls, 澳洲幸运5官方开奖结果体彩网:mo🌃r𝕴tgage rates typically decline as well. And that's what we saw for the first two days after Trump's annou🌞ncement, which occurred on a ꦐWednesday afternoon.

But by the following Monday, Treasury yields abruptly reversed course. And they didn't stop for five days. By the end of last week, the 10-year Treasury yield had surged an eye-popping 47 basis points. It was the 澳洲幸运5官方开奖结果体彩网:biggest weekly increase since the financial crisis of 2008.

This was terrible news for house hunters waiting to lock in a more affordable 澳洲幸运5官方开奖结果体彩网:mortgage rate. As recently as early March, the 30-year mortgage rate average clocked in at a four-month low of 6.50%. But after rising 44 basis points last week, Friday's flagship mortgage average had shot up to 7.14%. It was the 澳洲幸运5官方开奖结果体彩网:largest Friday-to-Friday increase in almost three years.

How Experts Explain the Bond Market Surprise

Many financial experts have been scratching their heads about the dramatic turn of events for 澳洲幸运5官方开奖结果体彩网:Treasury yields, as the stock market continued tumbling through last Tuesday (before beginning a slo♏w recovery Wednesday). What caused bond prices to sink at the same time that the stock market was also still declining?

One theory is that investors predict tariff-triggered trade wars will push 澳洲幸运5官方开奖结果体彩网:inflation higher by way of more expensive consumer goods. If inflation rises, that could force the Federal Reserv🦂e to keep interest rates high for longer. And that, in turn, makes locking in today's Treasury rates less appe🍸aling—driving their price down.

Another top theory is that Trump's stricter-than-expected global tariffs could cause foreign governments to retaliate by 澳洲幸运5官方开奖结果体彩网:dumping their U.S. bonds. Or even aside from retaliation, countries may opt to buy fewer new U.S. bonds going forward. In both cases, this could drive U.S.๊ bond prices lower.

In all scenarios right now, the dominant theme is "uncertainty". With it unclear which countries will retaliate, which will negotiate, and which tariffs President Trump may choose to retract or soften—and, as a result, how inflation and economic growth will be impacted—markets and the Federal Reserve are in a state of limbo awaiting greater market clarity. The Fed next meets on May 6–7, and at this time, interest rate traders have priced in a greater than 80% probability that the central bankers will leave rates where they are.

As for mortgage rates, they have seen a slight bit of relief so far this week, with 澳洲幸运5官方开奖结果体彩网:a mild drop Monday, and Tuesday rates moving lower still. But where they go fr🔴om here is difficult to pඣredict
