Mark Zandi Says Higher Rates Are Already Starting To Damage The Economy

The Federal Reserve raised interest rates at its September meeting over the public objection of one of the country’s most widely cited economists. Mark Zandi, chief economist at Moody’s Analytics, had warned in the run-up to the decision that hiking again would be a “serious Fed policy mistake.” The Fed raised them anyway — and now, with the 10-year Treasury yield trading above 5 percent, Zandi says the damage he predicted is already showing up in the real economy.

The dispute matters far beyond the Federal Reserve’s marble corridors, because the number doing the damage is not the central bank’s own policy rate. It is the long end of the Treasury curve. The 10-year yield is the baseline price of money for mortgages, corporate bonds, car loans and every financial asset priced off a discount rate, and above 5 percent it puts the economy in territory it has not had to live with in a generation. The bills for that move arrive on their own schedule — and they are starting to arrive.

The Warning That Came Before the Hike

Zandi’s objection was not that inflation was solved; it was about sequencing and fragility. His argument, laid out before the September meeting, was that the economy was already losing momentum on its own, that credit conditions were tightening without any additional help from the central bank, and that the full effect of previous hikes was still propagating through the system, since monetary policy works with a lag measured in quarters, not weeks. Raising rates into that combination risks overshooting — inflicting more damage on growth and employment than the final increment of inflation control is worth.

Central bankers weigh that trade-off differently. The Fed’s institutional instinct is that credibility is asymmetric: if the public begins to doubt the inflation target, clawing expectations back costs far more than the growth sacrificed to keep them anchored. In September, the committee effectively judged that protecting the target was worth the risk of leaning on an economy that was already bending.

Where the Damage Shows Up First

Housing is the first place a 5 percent long bond does its work. Mortgage rates track the 10-year, and with the benchmark above 5 percent, 30-year borrowing costs sit at levels that freeze transactions on both sides of the market. Owners holding mortgages priced years ago have a powerful financial reason not to sell, so supply stays thin; builders shelve projects; and first-time buyers face monthly payments that no amount of house-hunting cleverness can escape. Almost none of that shows up in a growth report immediately. It shows up first as quiet non-transactions, and only later in the hiring data.

The second wave lands on business balance sheets. Companies that gorged on cheap debt in the low-rate years are rolling into a market where refinancing costs hundreds of basis points more, and the decision calculus shifts from expansion to preservation. Small businesses, which borrow on floating rates and credit lines, feel it fastest of all. Consumers feel it in revolving debt, where card APRs have floated to records — while, on the other side of the ledger, the income from safe alternatives like Treasury bills and money market funds has finally become genuinely worth having. A 5 percent world takes with one hand and gives with the other; which hand you feel depends on whether you are a borrower or a saver.

Living in a 5 Percent World

A 10-year above 5 percent reprices every asset in the system, which is why economists like Zandi treat the long yield — not the funds rate — as the economy’s true thermostat. Equities face a higher discount rate, which compresses valuations hardest for companies whose profits are promises about the distant future. Bonds, for the first time in years, offer income worth having. Real estate has to clear at higher cap rates, which is a polite way of saying prices drift lower. And cash is no longer trash: a guaranteed 5 percent from the Treasury is competition for every risk asset on earth, and it wins more often than investors raised in the 2010s instinctively expect.

What This Means For You

If you are buying a home: watch the 10-year Treasury, not the Fed’s meeting calendar. Mortgage rates follow the long bond, and the spread between the two is where your negotiating room lives. In a 7 percent world, run the break-even math on paying points honestly — and treat any future rate cuts as a bonus, not a plan.

If you carry revolving debt: paying it down is the highest guaranteed return available anywhere in the market right now. A card charging 25 percent against a savings account paying 5 is a 20-point arbitrage working against you; close it as fast as the budget allows.

If you are a saver: this is the best income environment in decades, and it will not be permanent. Laddering Treasuries or CDs captures today’s yields while keeping your options open for whenever the cycle finally turns.

If you invest: expect the valuation argument to stay loud. Higher discount rates are structural pressure on richly priced growth stocks and a genuine tailwind for businesses that throw off cash today. Revisit the duration of your bond holdings — and let Zandi’s warning double as a reminder that decisions made at one Fed meeting reach paychecks and portfolios with a long, uneven lag.
