Every asset you can trade is a promise to pay money in the future. A stock is a claim on earnings that mostly arrive years from now. A bond pays coupons on a schedule. A currency pays whatever interest its central bank sets on cash held in it. When the price of future money changes, every one of those promises has to be repriced. That price is the interest rate, and it is why traders in every market stop what they are doing when a central bank speaks.
The goal here is a mental model, not a forecast. Understand the one mechanism that links stocks, bonds, currencies, and commodities, and a lot of confusing market behavior stops being confusing. One warning: most of what follows describes tendencies, not laws. The relationships are grounded in arithmetic, but their sign and strength shift with the market environment — the sections below flag where.
What "the Fed raises rates" actually means
The Federal Reserve does not set your mortgage rate, your broker's margin rate, or the yield on a corporate bond. It sets one thing: the interest rate banks charge each other to borrow cash overnight, the federal funds rate. Every other rate in the economy is built on top of that number.
It propagates because the policy rate defines the return on riskless cash. If overnight money earns 5%, no rational lender accepts less than 5% for anything riskier or longer. The policy rate becomes the floor under every borrowing cost and the baseline against which every risky return is measured. Raise the floor and everything above it has to reprice to stay attractive. Other central banks do the same job for their currencies, which is why "watching the Fed" is shorthand for watching the price of money everywhere.
An interest rate is the price of time. Every asset price is a claim on future money. Change the price of time and every claim reprices.
Stocks: the discounting machine
A share is a claim on a company's future earnings. To value it, you translate those future earnings into what they are worth today — you discount them. The discount rate is built on the interest rate. Higher rates mean each future dollar of earnings is worth less right now, so the price can fall even if the underlying business has not changed at all.
How much less depends on when the earnings arrive. Here is the present value of $100 discounted at 2% versus 5%, across different time horizons:
Present Value of $100 Discounted at 2% vs 5%
Notice the shape. A dollar arriving next year barely cares about the rate — $100 is worth $98.04 at 2% and $95.24 at 5%, a 2.9% difference. A dollar arriving in twenty years is gutted by the same move: $67.30 versus $37.69, a 44% haircut. This is the whole intuition behind duration. Assets whose payoffs sit far in the future are far more sensitive to rates than assets that pay now.
That is why rising rates tend to punish long-duration growth stocks — companies whose profits are mostly a distant promise — more than mature dividend payers whose cash is arriving today. It is also why a single rate move can hit two names inside the same stock index very differently; the index level hides a tug-of-war between its growth and value components. And there is a second channel stacked on top: higher rates slow borrowing, spending, and investment, which compresses the earnings themselves. So valuations fall for two reasons at once — the future dollars are discounted harder and expected to be fewer. When you read an earnings report, the discount rate is the invisible number sitting behind every forward estimate.
Bonds: the seesaw
Bonds show the mechanism in its purest form. A bond pays a fixed coupon. If you own one paying 3% and new bonds start paying 5%, nobody wants yours at the old price, so its price falls until its effective yield matches the 5% on offer. Rates up, existing bond prices down. It is a seesaw, and it is mechanical rather than sentimental.
The longer the bond's maturity, the bigger the price swing for a given rate move — the same duration idea from the stock section, applied to fixed coupons. Most Otrai readers trade rather than hold bonds, but the mechanism matters because bond yields are the raw material for everything else: equity valuations, currency flows, and the "risk-free rate" that anchors every model.
Currencies: chasing the yield
Money flows toward higher real returns. If US cash pays 5% and euro cash pays 2%, capital tends to move into dollars to earn the difference, pushing the dollar up. This is the engine behind the carry trade: borrow the low-yield currency, hold the high-yield one, and collect the gap — a strategy that works until the exchange rate moves against you and erases weeks of carry in a single day.
The critical subtlety is that currencies move on rate expectations, not just actual decisions. By the time a central bank hikes, the market has usually priced it in for weeks. What moves the currency is the surprise — a decision or a tone that shifts the expected path of future rates. This is why a currency can fall on a rate hike when the hike lands smaller than expected, and why trading a currency pair around rate decisions rewards reading the expected path rather than the headline. The event mechanics of a rate announcement are a subject in their own right.
Commodities and the dollar
Most commodities — oil, gold, copper — are priced in dollars globally. When rising US rates push the dollar up, each dollar buys more of the commodity, so its dollar price tends to fall, all else equal. There is a second drag: commodities pay no interest. When cash yields 5%, the opportunity cost of holding a lump of non-yielding metal rises, which weighs on assets like gold whose main appeal is not income. Both are tendencies, not guarantees — a supply shock or a safe-haven panic can overwhelm the rate effect entirely.
Here is the whole cross-asset picture in one place, with the standard direction for rising rates:
How Each Market Typically Responds to Rising Rates
| Asset Class | Core Mechanism | Typical Response to Rising Rates |
|---|---|---|
| Long-duration growth stocks | Distant earnings discounted harder | Falls most |
| Dividend / value stocks | Near-term cash, less rate-sensitive | Falls less |
| Bonds | Fixed coupons vs higher new yields | Prices fall (the seesaw) |
| Domestic currency | Capital chases the higher yield | Tends to strengthen |
| Commodities / gold | Priced in dollars, pay no yield | Tends to soften |
Read that table as a starting hypothesis, not a rule. Every row carries an "all else equal" that the real world rarely grants.
Why "good news is bad news" happens
Here is the insight that turns this from a list into a system. Near a policy turning point, a strong jobs report or a hot inflation print can send stocks down. That looks insane until you translate it: strong data implies the central bank keeps rates higher for longer, which discounts every future earnings stream harder. The market is not trading the headline, it is trading the headline's implication for the price of money. Good news for the economy becomes bad news for asset prices whenever the dominant worry is rates.
And here is the honest caveat, because this is exactly where mechanical thinking gets traders hurt: the relationship is regime-dependent. In an inflation-fighting environment, stocks and bonds can fall together and good news is bad news. In a growth-scare environment, good news is good news again and the correlation flips sign — the stock-bond correlation has swung between positive and negative across different eras. The mechanism is stable; which way it points depends on what the market is most afraid of, and that is a property of the prevailing regime, not a constant.
What a trader actually does with this
You do not need to forecast the central bank. You need three habits.
First, know roughly where you are in the cycle — hiking, holding, or cutting — because that sets which of the tendencies above is currently in force. Second, watch expectations, not headlines: the futures-implied path of rates tells you what is already priced, and markets move on the gap between that path and reality. Third, and most useful, check whether your positions are secretly the same bet.
The Same Rate Bet in Disguise
| Position | Looks Like | Secretly a Bet On |
|---|---|---|
| Long growth / tech stocks | Equity exposure | Falling or low rates |
| Long long-dated bonds | Safe income | Falling rates |
| Short the US dollar | An FX view | Falling US rates |
| Long gold, unhedged | Inflation hedge | Low real rates |
Stack those four and you do not hold a diversified book — you hold one leveraged rate position wearing four costumes, and a single hawkish sentence can sink all of them at once. Even crypto has spent recent cycles trading like a long-duration risk asset that follows the liquidity cycle rates help drive. The final table sketches how the tendencies shift across the phases of a rate cycle. Treat it as a map of what has often worked, not a promise of what will.
Rate-Cycle Phases and Their Tendencies
| Cycle Phase | Rate Direction | Tends to Do Well | Tends to Struggle |
|---|---|---|---|
| Early hiking | Rising off lows | Value, financials, cash | Long bonds, growth |
| Late hiking / peak | High, near the turn | Cash, short duration | Rate-sensitive everything |
| Early cutting | Falling | Growth, long bonds | The dollar |
| Low and holding | Near the floor | Risk assets broadly | Cash, which earns little |
Key takeaways
- The policy rate is the price of overnight money for banks. It sets the baseline return on riskless cash and propagates into every valuation.
- Every asset is a claim on future money, so a change in rates reprices everything — hardest for the payoffs furthest in the future. That is duration.
- Stocks fall on two channels: harder discounting and compressed earnings. Bonds move on the seesaw. Currencies chase yield and trade on expectations. Commodities feel the stronger dollar and the cost of holding non-yielding assets.
- "Good news is bad news" is the market trading the policy implication of data — but its sign is regime-dependent, not a law.
- Check whether your open positions are one rate bet in disguise, and watch the futures-implied path rather than the headline decision.
You cannot trade any market seriously without a view on the price of money. Even "I have no view" is a position, and rates will reprice it for you regardless.
