March mortgage rates forecast

Mortgage rates are more likely to go up than go down in March. Blame the Federal Reserve.

As for the Russian invasion of Ukraine, the effects are so unpredictable that I won't begin to guess the implications for mortgage rates. War could impel investors toward buying safe investments like mortgage-backed securities, which would cause mortgage rates to fall. But a spike in fuel prices could cause inflation to rise, nudging mortgage rates higher.

March is a pivotal month for the Federal Reserve, as it begins in earnest to pull interest rates upward using two techniques. The first consists of raising the federal funds rate, which is an interest rate that banks charge one another for overnight loans. When you read articles that say the Fed is raising interest rates, they're usually referring to the federal funds rate.

This overnight rate is important because it acts as a floor for other interest rates. Mortgage rates are set by market forces and don't react directly to the ups and downs of the federal funds rate. Sometimes mortgage rates initially move in the opposite direction, for example, falling immediately after a surprise Fed increase. But in the longer run, mortgage rates tend to move in the same direction as the federal funds rate.

The Fed's second technique consists of expanding or shrinking its vast government and mortgage debt holdings. During the pandemic, the central bank expanded these holdings to stabilize the financial system and reduce interest rates. By mid-February, the central bank owned $5.7 trillion in U.S. Treasurys (government debt) and $2.7 trillion in mortgage-backed securities.

Now the Fed wants to reduce those holdings. However, it has to do so carefully because interest rates could rise fast if the Fed acts aggressively. The central bank is aware that mortgage rates jumped in late 2021 after the Fed took the mild action of reducing its monthly debt purchases.

The central bank's monetary policy committee is scheduled to meet March 15-16. It's expected to increase the federal funds rate to fight inflation. March is also when the Fed plans to stop buying government and mortgage debt altogether.

The Fed is likely to reduce those debt holdings passively at first. It won't replace government bonds as they mature or mortgage bonds as the loans are paid off. But eventually, the Fed will reduce its holdings actively by selling them. That could force all kinds of interest rates higher. Fed policymakers have been arguing publicly over the timing of these sales — whether they should begin in a few months or a couple of years.

The central bank will discuss its portfolio reduction plans at the March meeting, but it's unlikely to announce a timetable.

Mortgage rates may rise before the meeting as the market braces for the first increase in the federal funds rate since 2018. And mortgage rates are likely to keep rising as markets digest the Fed's determination to curb inflation with interest rate increases.

What happened in February

Mortgage rates went up about four-tenths of a percentage point in February, about as much as they had gone up in January.

In late January, I predicted that mortgage rates would "edge upward in February as the Federal Reserve moves toward restoring bond markets to normal." Rates did more than "edge upward"— they rose decisively.

I thought mortgage rates would slow their rise in February because they had gone up significantly in January. But rates continued to rise as the Fed clearly indicated its willingness to push long-term rates higher.
