What Does Lowering the Discount Rate Do?

Lowering the discount rate makes it cheaper for banks to borrow money directly from the Federal Reserve, which ripples outward through the entire economy. Banks pay less for short-term loans, so they can offer lower interest rates to businesses and consumers. This encourages more borrowing, more spending, and faster economic growth. The current primary credit rate sits at 3.75 percent.

How the Discount Rate Works

The discount rate is the interest rate the Federal Reserve charges commercial banks when they borrow money through what’s called the “discount window.” Banks sometimes need short-term cash, usually overnight, to meet their obligations or manage unexpected demands from depositors. The Fed acts as a lender of last resort, providing that liquidity in exchange for collateral and an interest charge.

There are actually three tiers. Primary credit goes to financially healthy banks at the standard discount rate. Secondary credit is available to banks that don’t qualify for primary credit, at a higher rate. Seasonal credit uses a floating rate tied to market conditions. When people talk about “the discount rate,” they’re almost always referring to the primary credit rate.

Each regional Federal Reserve Bank’s board of directors proposes the rate, but the Board of Governors in Washington has final say. This makes it a directly controlled policy lever, unlike market-driven rates that fluctuate on their own.

Discount Rate vs. Federal Funds Rate

These two rates are often confused, but they serve different purposes. The federal funds rate is what banks charge each other for overnight loans. The discount rate is what the Fed itself charges banks for overnight loans. The Fed sets a target for the federal funds rate and uses open market operations (buying and selling Treasury securities) to nudge it into place. The discount rate, by contrast, is set directly by the Fed’s leadership.

The discount rate is intentionally set higher than the federal funds rate, typically by a full percentage point. This gap exists to discourage banks from running to the Fed first. They’re expected to borrow from each other before turning to the discount window. In practice, discount window borrowing is a tiny fraction of total interbank lending. But the rate still matters because it acts as a ceiling on short-term borrowing costs and signals the Fed’s broader policy direction.

What Happens When It Goes Down

When the Fed lowers the discount rate, it reduces the cost of the safety net that banks rely on. Banks that previously hesitated to extend loans because they were worried about having enough cash on hand can now borrow from the Fed more cheaply if they need to. This makes banks more willing to lend. If market rates rise above the primary credit rate, banks are actually encouraged to borrow at the discount window and lend that money out, pushing rates back down across the system.

The real power is in the chain reaction. Cheaper borrowing for banks translates into cheaper borrowing for everyone else. Businesses can take out loans to buy equipment, hire workers, or expand into new markets at a lower cost. Households find it easier to finance a car, carry a credit card balance, or take on a mortgage. The Fed itself describes this mechanism plainly: when interest rates go down, households are more willing to buy goods and services, and businesses are in a better position to purchase property and equipment.

That increased spending creates greater demand for goods and services, which pushes businesses to hire more workers. More employment means more income circulating through the economy. It’s a self-reinforcing cycle, at least for a while.

Effects on Consumer Interest Rates

If you’re carrying debt or planning a major purchase, a lower discount rate is generally good news. Mortgage rates, credit card rates, and auto loan rates all tend to move lower as the Fed eases policy. Harvard economist Jason Furman has noted that mortgage rates are “more likely to continue to move down as the Fed continues to ease policy.”

The relationship isn’t instant or perfectly proportional, though. Consumer interest rates don’t just reflect the current Fed rate. They also bake in expectations about where rates will go in the future, along with risk factors like creditworthiness and loan duration. By the time the Fed actually cuts a rate, markets have often already priced in the move. So you might see mortgage rates start dropping weeks before an official announcement, then barely budge when the cut happens. Even after rate reductions begin, consumer rates can remain elevated for a year or more as the full effects work through the system.

Effects on the Stock Market

Lower rates tend to be a tailwind for stocks, for several interconnected reasons. Borrowing costs drop for companies, which directly improves profit margins, especially for smaller and more debt-dependent businesses. The Russell 2000 index, which tracks smaller companies, hit a record high in early December 2024 as rate-cut expectations climbed. José Torres, senior economist at Interactive Brokers, explained why: “When you have lower rates, their interest expenses drop heavily, and that widens their profit margins.”

There’s also a portfolio effect. When rates fall, the returns on savings accounts, money market funds, and short-term government bonds shrink. That makes stocks comparatively more attractive to investors looking for better returns, driving more money into equities. Sectors like real estate, manufacturing, and small business tend to benefit the most because they’re more sensitive to financing costs.

The Inflation Trade-Off

Lowering the discount rate is not without risk. The same mechanism that stimulates growth can also fuel inflation. When more people are borrowing and spending, demand for goods and services rises. If supply can’t keep up, prices go up. Businesses competing for workers may raise wages, which raises production costs, which raises prices further.

This is why the Fed treats rate cuts as a balancing act. Cutting too aggressively or too early can overheat the economy and trigger the kind of inflation that erodes purchasing power. Cutting too slowly or too late can allow a recession to deepen unnecessarily. The Fed monitors employment and inflation data continuously, adjusting the rate in response to what the economy actually needs rather than following a fixed schedule.

Why the Fed Lowers It

The Fed typically lowers the discount rate during economic slowdowns or periods of financial stress. The goal is to keep credit flowing. During market turbulence, banks may become reluctant to lend, even to each other. A lower discount rate reassures them that cheap backup funding is available, which prevents the kind of credit freezes that can turn a downturn into a crisis. The Fed describes the discount window’s core purpose as helping banks “avoid actions that have negative consequences for their customers, such as withdrawing credit during times of market stress.”

In calmer times, a rate cut signals that the Fed wants to stimulate economic activity. It’s one tool in a larger kit that includes open market operations and adjustments to the federal funds rate target. These tools work together. A discount rate cut on its own sends a signal, but paired with a lower federal funds rate target and active bond purchases, it becomes part of a coordinated push to loosen financial conditions across the entire economy.
