Definition
A giant step (known in the U.S. as a "jumbo" rate hike) is when a central bank raises its benchmark interest rate by 0.75 percentage points (75 basis points) all at once. Normally, central banks adjust rates carefully, 0.25 points at a time, so they don't shock the economy. But when prices are surging too fast, they take a much bigger stride to cool an overheated economy quickly.
Why jump three steps at once
On an ordinary staircase, you place your feet carefully one step at a time so you don't trip. Central banks do the same. They usually raise the benchmark rate by 0.25 percentage points so the market isn't caught off guard. It's as careful as a toddler's first steps, so it's called a "baby step."
When prices climb a bit faster, a central bank may take two steps at once and raise rates by 0.50 percentage points. This is called a "big step." But when war or global supply chain disruptions send prices soaring out of control, normal strides can't keep up with inflation that spreads like wildfire.
That's when a central bank makes the bold call to leap three steps like a giant with long legs and raise rates by 0.75 percentage points at once. This is the giant step. It sends a strong signal to everyone in the market: "We will use every tool we have to bring prices under control."
How it hits your wallet and daily life
When a central bank takes a giant step, the loan rates at commercial banks tend to rise quickly too. If you have a variable-rate mortgage or personal loan, your monthly interest payments can jump sharply depending on how much you owe, putting real pressure on your household budget.
As interest costs grow, people cut back on dining out and shopping. Companies put off plans to borrow money to build factories or hire new workers. As less money flows through the economy, prices slowly settle down.
But if rates rise too steeply, spending and investment can freeze up. That raises the risk of a painful side effect: a recession. In other words, the economy accepts slower growth as the price of taming runaway inflation.
A closer look: the power of 75 basis points
In financial markets, rate changes are usually measured in "basis points," or bp. One basis point equals 0.01 percentage points, so a giant step is an unusual 75 bp hike in one go. The number 0.75 may look small, but in markets where trillions of dollars move, it creates a huge wave.
In 2022, the U.S. Federal Reserve (the Fed) raised rates by 75 basis points four times in a row to fight the worst inflation in 40 years. The U.S. holds the world's reserve currency (the money at the center of international trade). So when it raised rates sharply, investment money from around the world rushed toward the dollar for its higher returns.
The dollar soared in value. Many countries then faced a chain reaction, and to stop their own currencies from sinking and import prices from rising, they had to raise their own rates in response.
Common misconceptions
After a giant step, every loan rate at commercial banks rises by exactly 0.75 percentage points.
The 0.75 points is the increase in the central bank's benchmark rate. Commercial bank loan rates depend on market rates, the bank's own markup, and the loan type (variable or fixed), so they can rise by more or less than the benchmark. Loans already taken out at a fixed rate don't change right away.
Where you meet it
In 2022, the U.S. Federal Reserve raised its benchmark rate by 0.75 percentage points four times in a row to fight surging prices.
In the U.S. in 2022, after the Fed's back-to-back giant steps, mortgage rates climbed fast and borrowers' interest costs rose sharply.
In one sentence
A giant step is a powerful tightening move in which a central bank raises its benchmark rate by 0.75 percentage points at once to tame surging prices.
