Every day, traders watch gold, tech stocks and the Australian dollar move, looking for the next catalyst. But behind many major market moves sits another force that can shape direction: bond yields.
Many traders treat bonds as something only institutional investors need to follow. That can leave a major part of the market story out. When yields move, the effect can flow into markets far beyond bonds.
Why bond yields matter
Bond yields are one of the market’s main signals for the cost of money. When yields rise or fall, they can influence currencies, equities, gold and risk appetite because they change how investors value future returns.
What bond yields actually are
At its most basic level, a government bond is a loan from investors to a government.
When an investor buys a bond, they are lending money to that government for a fixed period. In return, the government agrees to pay a fixed amount of interest each year until the bond matures and the original money is returned.
You do not need to trade bonds to understand why they matter. What matters is not only the bond itself, but the return on that bond. That return is called the yield, and it can tell traders how the market is pricing inflation, growth, central bank policy and risk.
When commentators say “yields are rising” or “the yield curve has shifted”, they are usually talking about government bond yields.
The Lifecycle of a Government Bond
1
The Loan
An investor buys a bond, effectively lending capital to the government for a fixed period.
2
The Interest
The government agrees to pay a fixed, recurring amount of interest every year.
3
Maturity
The bond's term ends, and the government returns the original money to the investor.
The Yield
The actual return an investor makes on this process. It acts as a live market signal for inflation, growth, Fed policy, and risk.
Why bond prices and yields move in opposite directions
This is one of the key concepts to understand: bond prices and bond yields move in opposite directions. When bond prices rise, yields fall. When bond prices fall, yields rise.
It can feel counterintuitive at first, but the mechanism is straightforward once the coupon payment is fixed.
How does it work?
Let’s say an investor buys a new government bond for US$100, and it pays a fixed US$5 interest payment every year. The yield on that investment is 5%.
Now imagine the economy slows and investors seek the perceived safety of government bonds. Demand increases, which pushes the price of the bond up to US$110 in the open market. The government is still only paying that same fixed US$5 a year. If a new investor buys the bond at US$110, the yield on that US$5 payment falls to about 4.5%.
The price went up, but the yield went down.
Conversely, if investors sell bonds to buy riskier assets, the price of the bond may drop to US$90. That same fixed US$5 payment now represents a higher yield of about 5.5%.
The price went down, but the yield went up.

Two key Treasury yields traders often watch
Traders do not need to follow the entire bond market. Two US government bond yields often receive the most attention because they send different signals.
The US 2-year Treasury yield reflects the market’s near-term expectations for central bank policy. Because it matures in two years, it is highly sensitive to what traders believe the Federal Reserve may do with interest rates at upcoming meetings.
The US 10-year Treasury yield reflects the market’s view of longer-term economic growth, inflation and risk appetite. It is the benchmark borrowing rate for the global economy. When commentators say “yields are rising”, they are often referring to the 10-year yield.
The difference between yields across maturities is known as the yield curve. A changing yield curve can suggest shifts in expectations for growth, inflation and monetary policy.
What moves bond yields
Bond yields do not move in a vacuum. They respond to macroeconomic data, central bank signals, investor positioning and risk sentiment.
Understanding which force is currently driving the move can help traders avoid reacting only to the headline and start reading the context behind it.
What moves bond yields
When inflation rises, or is expected to rise, investors may demand higher returns to compensate for the loss of purchasing power.
Yields may rise
When inflation data surprises to the upside or when markets expect central banks to keep rates higher for longer.
Yields may fall
When inflation cools, rate expectations ease or investors believe the inflation threat is becoming less persistent.
Central bank expectations are especially important for shorter-dated yields. The US 2-year Treasury yield often moves sharply when markets reprice the likely path of Federal Reserve policy.
Yields may rise
When the Fed signals rate hikes, delayed cuts or a higher-for-longer policy stance.
Yields may fall
When the Fed signals a possible pivot, slower inflation or weaker growth.
The 10-year yield is heavily influenced by the market’s view of long-term growth.
Yields may rise
When growth is strong and investors move from bonds into risk assets, pushing bond prices lower.
Yields may fall
When growth slows, recession fears rise or investors seek the perceived safety of government bonds.
During periods of stress, bond yields can move in ways that appear to contradict the economic data.
Yields may rise
In a risk-on environment, investors may sell bonds and move into equities or other risk assets. That can push bond prices lower.
Yields may fall
In a risk-off environment, investors may buy government bonds for perceived safety. That can push bond prices higher.
