Part three of GO's educational series, designed to help new traders understand the key forces that shape global markets.
You watch the screen at 2:00 pm. The central bank announces it is holding rates steady. It is exactly what the market expected. Yet the S&P 500 rallies 1% and the US dollar falls.
If a move like this has ever caught you off guard, you are not alone. Many traders know interest rates matter, but struggle to explain why a rate hold, with no change at all, can still trigger sharp market volatility.
Central bank interest rates are often described as the price of money. Because the price of money affects how investors value many assets, rate expectations can be one of the key forces shaping markets.
What a central bank interest rate actually is
At its core, a central bank interest rate is the rate at which a central bank lends money to commercial banks. That rate then flows through to the broader economy and financial markets.
You do not need a degree in economics to trade. But it helps to understand who is setting the price of money, and how markets respond when that price is expected to change.
There are five major central banks that play a key role in global capital flows:
- • The Federal Reserve (Fed) sets the benchmark cost of capital for the US economy and has a major influence on global financial conditions.
- • The Reserve Bank of Australia (RBA) influences domestic borrowing costs and the Australian dollar (read how the RBA works).
- • The European Central Bank (ECB) steers the Eurozone economy and can influence cross-border currency flows.
- • The Bank of England (BoE) steers the UK economy and heavily influences the British pound.
- • The Bank of Japan (BoJ) remains an important anchor for global liquidity and currency markets.

Hawkish and dovish: the two words traders need to know
If you read financial commentary, you will quickly encounter two words: hawkish and dovish. These terms describe the direction a central bank appears to be leaning. They are not the same as good or bad.
A central bank is hawkish when it leans toward higher interest rates or tighter monetary policy to manage inflation. For example, if a central bank governor says, “We remain highly attentive to inflation risks and are prepared to act,” the market may interpret that as a hawkish signal.
A central bank is dovish when it leans toward lower rates or easier policy to support economic growth. If a governor notes that “downside risks to the labour market have increased,” traders may read that as a dovish shift.
Markets can trade these changes in tone just as aggressively as the actual rate decision.
- Leans toward lower interest rates
- Focuses on supporting economic growth
- Often weakens the domestic currency
- Generally supports equities and gold
- Leans toward higher interest rates
- Focuses strictly on managing inflation
- Often strengthens the domestic currency
- Generally pressures equities and gold
A central bank decision is only part of the story. Markets usually move on the difference between what happened and what traders expected to happen.
For example, a rate hold can still push markets sharply if the central bank sounds more hawkish than expected. A rate hike may have little impact if traders had already priced it in. The key question is not just, ‘Did they hike, hold or cut?’ It is, ‘Did this change where rates may go next?’
Why markets move before the decision is made
This is the critical concept: markets do not wait for central bank decisions. They price in the expected path of rates in advance.
When a central bank announces a rate decision that matches market expectations, the reaction may be limited. The bigger moves often come when the decision, statement or press conference differs from what had already been priced.
Imagine a scenario where traders expect a central bank to hike rates three times this year. If the bank hikes today but hints that this may be its final increase, the market could treat that hike as a dovish surprise. Equities may rally even though the rate was increased.
A rate cut can disappoint if traders expected a bigger cut, or if the central bank signals fewer cuts ahead. A rate hike can be taken well if it is smaller than feared, or if the outlook sounds less aggressive.
Before assessing a central bank decision, the key question is: what had the market already priced in?
Traders also watch a concept known as the terminal rate. This is the rate the market expects a central bank to reach at the end of a hiking or cutting cycle.
The terminal rate matters because it helps anchor bond yields, equity valuations and foreign exchange (FX) rate differentials. If terminal rate expectations shift higher, markets may reprice sharply, even if the current interest rate has not changed.
What drives rate expectations
Rate expectations are constantly shifting. They are pushed and pulled by incoming economic data that forces traders to reassess what a central bank may do next.
Inflation is a key input into rate decisions. Hot CPI can trigger hawkish repricing, support the US dollar, weigh on gold and pressure bonds.
Inflation runs hotter than expected, meaning central banks may need to hike more or hold rates higher for longer.
Inflation cools faster than expected, giving central banks more room to cut.
A strong jobs market can delay cuts. A weaker one can bring them forward. This is why payrolls data can move major markets.
Employment is strong and wages are rising, suggesting the economy may absorb higher rates.
Jobs weaken and unemployment rises, increasing pressure to support growth.
Growth divergence between countries can drive FX. The country with stronger growth and higher expected rates may attract more capital.
Growth is resilient, reducing the need for lower rates.
Growth slows or contracts, increasing the chance of easier policy.
Markets often react more to guidance than the rate decision itself. A hawkish hold or dovish cut can move markets more than a straightforward decision.
A governor signals concern about inflation, hints at further hikes or suggests rates may stay higher for longer.
A governor flags economic weakness, signals cuts are possible or says cuts have been discussed.
The 2023 US banking stress showed how financial stability concerns can temporarily outweigh inflation-fighting priorities.
Banking stress, credit events or market dysfunction may push central banks to pause despite inflation risks. Systemic risk events can trigger emergency cuts outside scheduled meetings.
How surprises can move markets
The rate decision is only one part of the story. The market reaction depends on what happened compared with what was expected.
How rate expectations move the markets you trade
Because the dollar is the pricing unit for so many global assets, its movement mechanically affects their prices. Four connections matter most for traders already active in these markets.
Bonds
Rate expectations are a major driver of short-term bond yields. When rate cut expectations rise, bond prices tend to rise and yields tend to fall. When hike expectations rise, bond prices tend to fall and yields tend to rise. Trace these inverse tracking shifts inside our detailed framework explaining what bond yields are.
Equities
Higher interest rates increase the discount rate applied to future earnings. This can reduce the present value investors assign to growth companies. That is why rate-sensitive indices such as the Nasdaq can fall sharply when rate expectations rise unexpectedly.
Gold
Higher rate expectations can push real yields higher. That increases the opportunity cost of holding gold, which pays no income. Lower rate expectations can support gold by reducing that opportunity cost.
FX, including AUD/USD and EUR/USD
Interest rate differentials between countries are a key driver of exchange rates. When the Fed is expected to hold rates higher for longer than the RBA, the rate differential may favour the US dollar and weigh on AUD/USD.
Crypto, including Bitcoin
Higher rate expectations can reduce appetite for high-risk, high-beta assets as capital moves toward safer, yield-bearing instruments. Lower rate expectations can support liquidity-driven assets, including Bitcoin, although crypto markets can also be affected by regulation, sentiment, positioning and asset-specific factors.
When interest rates matter most
You do not need to monitor every central bank speaker every day. But there are specific windows where rate expectations can move quickly.
-
Scheduled central bank meetings matter, particularly the press conferences that follow the rate decisions.
-
Major data releases, such as CPI and monthly jobs data, can also reprice market expectations quickly.
-
Unscheduled speeches or statements from central bank governors can matter too, especially if they suggest a shift in policy direction.
The market does not only trade where interest rates are today. It trades where interest rates are expected to go next.
Understanding that distinction can help explain why markets sometimes rally after a rate hike, fall after a rate cut or move sharply after a decision that appeared to deliver no change at all.
