Part two of GO's educational series, designed to help new traders understand the key forces that shape global markets.
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, they may change how investors price risk, growth, inflation and the cost of money across almost every market traders watch.
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 changes in government bond yields and what those changes may suggest about the broader financial system.
An investor buys a bond, effectively lending capital to the government for a fixed period.
The government agrees to pay a fixed, recurring amount of interest every year.
The bond's term ends, and the government returns the original money to the investor.
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.
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.
Higher yields driven by inflation can weigh on gold, growth stocks and rate-sensitive assets.
When inflation rises, or is expected to rise, investors may demand higher returns to compensate for the loss of purchasing power.
When inflation data surprises to the upside or when markets expect central banks to keep rates higher for longer.
When inflation cools, rate expectations ease or investors believe the inflation threat is becoming less persistent.
Fed expectations are one of the most important drivers of the 2-year yield and can flow directly into currency pairs, gold and equity indices.
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.
When the Fed signals rate hikes, delayed cuts or a higher-for-longer policy stance.
When the Fed signals a possible pivot, slower inflation or weaker growth.
The 10-year yield is often watched as a signal of long-run growth, inflation and market confidence.
The 10-year yield is heavily influenced by the market’s view of long-term growth.
When growth is strong and investors move from bonds into risk assets, pushing bond prices lower.
When growth slows, recession fears rise or investors seek the perceived safety of government bonds.
Yield moves during stress periods can reflect positioning, liquidity and safe-haven demand, not just fundamentals.
During periods of stress, bond yields can move in ways that appear to contradict the economic data.
In a risk-on environment, investors may sell bonds and move into equities or other risk assets. That can push bond prices lower.
In a risk-off environment, investors may buy government bonds for perceived safety. That can push bond prices higher.
Do not just watch whether yields are rising or falling. Watch why they are moving.
A yield rise driven by strong growth is different from a yield rise driven by sticky inflation. A yield fall caused by lower inflation is different from a yield fall caused by panic buying during a market shock.
The first may support risk appetite. The second may pressure valuations. The market impact can be very different in each case.
Three common bond yield scenarios to recognise
The scenarios below map a simple chain: macro catalyst, yield mechanism and potential asset impact.
CPI or inflation data comes in hotter than expected.
Weak labour market data or rising recession concerns.
Fed decision or data shifts future rate expectations.
Assuming a move in yields means the same thing every time.
For traders, a rising yield is not automatically positive or negative. It depends on the reason. A yield rise caused by stronger growth can send a very different signal from a yield rise caused by stubborn inflation or concerns about government debt supply.
The mistake is treating yields as a simple directional signal. They are not. They are a context signal, and that context can affect almost every market traders watch.
How yields may affect markets you trade
Once traders understand what yields are and why they move, they can map the potential impact across their trading screens.
1. Gold (XAU/USD)
Gold tends to move inversely with real yields, which are nominal yields adjusted for inflation. When real yields fall, gold may become more attractive because the opportunity cost of holding a zero-yield asset decreases. When real yields rise, gold can come under pressure because interest-bearing assets may become relatively more attractive.
2. Tech and growth stocks
Higher yields increase the discount rate applied to future earnings. This can weigh on growth stocks because much of their expected value is tied to earnings that may arrive years from now. That is one reason the Nasdaq 100 is often described as rate-sensitive.
3. US dollar
Higher US yields can attract foreign capital seeking better returns. That can increase demand for the US dollar, particularly when US yields are rising faster than yields in other major economies.
4. AUD/USD
AUD/USD is sensitive to the interest rate differential between the Reserve Bank of Australia and the Federal Reserve. When US yields rise faster than Australian yields, the rate differential may favour the US dollar and weigh on AUD/USD.
Typical directional impacts when US yields rise. Tendencies, not guarantees.
When yields may deserve closer attention
Bond yields do not need to be monitored every minute. However, there are specific windows when yield moves may have a stronger influence on market pricing.
-
CPI releases: Inflation data can move yields because it changes expectations for the Fed, real yields and the future path of interest rates. It can be useful to watch what the data implies for rates, not just whether the headline number is higher or lower than expected.
-
Federal Reserve meetings: Fed decisions, press conferences and forward guidance can directly reprice the short end of the yield curve. The statement, dot plot and chair’s comments may all influence whether markets expect tighter or looser policy ahead.
-
Non-Farm Payrolls and jobs data: Strong employment data can reduce expectations for near-term rate cuts. Weak labour market data can increase expectations for Fed easing. Both outcomes can move US yields significantly.
-
Major risk-off events: Geopolitical shocks, banking stress or sharp equity sell-offs can trigger sudden demand for perceived safe-haven assets, including US government bonds. In these periods, yields may fall quickly as bond prices rise, even if the underlying inflation backdrop has not changed.
Test your knowledge
Bond yields are not just something bond traders watch. They are one of the key inputs that can influence pricing across gold, currencies, equities and risk assets. When yields move, the key question is not only whether they moved up or down. It is why they moved, and which markets may be most sensitive to that change.
