CONCEPTWhy hiking rates cools the economy
The central bank moves just one number. That number travels through credit, spending and stocks until it reaches your wallet.
THE LEVER
1 rate
the price of money
THE EFFECT
slows
credit and spending
THE LAG
~12 months
not instant
THE IDEA
+0.25%
↑ the size of a typical rate hike
It sounds small, but that quarter point multiplies across a whole country's credit: mortgages, business loans, cards. That's why a tiny change in the rate moves the entire economy.
THE RULE
TO GET IT~12 months
~12 months
▲ how long a hike takes to fully bite
Like turning the thermostat in a huge house: the temperature doesn't change at once, it drops slowly over months.
A rate hike doesn't slow the economy today: it takes months to bite. That's why the central bank is always steering half-blind.
- TRANSMISSION
- — The path by which a rate hike reaches the real economy.
- LAG
- — The time between the central bank's decision and its visible effect.
KEY IDEA
SIMPLE RULEExpensive money slows the economy
“Hiking rates doesn't switch off inflation by magic: it makes credit pricier, cools spending, and over time slows prices.”
If borrowing costs more, fewer loans get taken. Fewer loans mean less spending and investment.
- CREDIT
- — The money banks and markets lend to households and businesses.
- DEMAND
- — Total spending by consumers and businesses in the economy.
- INFLATION
- — A broad, sustained rise in prices.
HOW IT WORKS
ILLUSTRATIVEThe economy cools with a delay
The brake takes time to bite. If the central bank hikes too far, by the time it reacts it may have broken something.
Hypothetical curve: after a rate hike, activity doesn't drop at once, it eases gradually over months.
- ACTIVITY
- — The pace at which an economy produces and spends.
- SOFT LANDING
- — Slowing the economy without triggering a recession.
THE STEPS
THREE LINKSHow a rate hike travels to your wallet
1. CREDIT GETS PRICIER
Mortgages, loans and cards rise. Borrowing costs more, so households and businesses borrow less.
2. SPENDING SLOWS
With pricey credit, big purchases and investments get postponed. The economy's total demand cools.
3. INFLATION EASES
If people spend less, prices stop rising so fast. That's the goal, though sometimes the brake arrives late and breaks something.
The chain has three links. Each one cools the economy a little more.
- MORTGAGE
- — A long-term loan to buy a home; its cost rises with rates.
- INVESTMENT
- — Company spending to grow: factories, equipment, hiring.
X-RAY
WHERE IT LANDSWhere a rate hike shows up
The same rate move squeezes credit and, at the same time, rewards savers. That's why it reshuffles the whole economy.
Illustrative split of the channels through which a rate change reaches the real economy.
- VALUATION
- — The price the market pays for future earnings.
- DEPOSIT
- — Money parked at the bank that earns more when rates rise.
WATCHLIST
EXAMPLESFive ETFs that react to rates
| TLT | - | → ≈ | Long bonds. Fall when rates rise: maximum sensitivity. |
| SHY | - | → ≈ | Short bonds. Barely move: the shelter while rates climb. |
| XLF | - | → ≈ | Banks. Often earn wider margins when rates rise. |
| XLU | - | → ≈ | Utilities. Suffer with high rates: they're compared to a bond. |
| KRE | - | → ≈ | Regional banks. Very sensitive to credit and the yield curve. |
Teaching examples of rate-sensitive assets. Not a recommendation: they illustrate each channel of the concept.
- ETF
- — A fund that tracks an index or sector, traded like a single stock.
- SENSITIVITY
- — How much an asset's price reacts to a rate change.
