A bond yield is a measure of the return an investor receives from holding a bond relative to its price. Traders watch government bond yields—especially US Treasury yields—because they influence borrowing costs, asset valuations, currency demand and the opportunity cost of holding non-yielding assets such as gold.
Key takeaways
- Bond prices and yields generally move in opposite directions.
- US Treasury yields are an important reference point for global financial markets.
- Higher yields can pressure long-duration growth stocks if discount rates rise.
- Real yields can be especially relevant for gold.
- The shape of the yield curve can reflect market expectations about growth, inflation and policy.
Why do bond prices and yields move opposite each other?
Imagine an existing bond pays a fixed coupon. If new bonds enter the market offering a higher return, the older bond becomes less attractive unless its market price falls. That lower price raises the effective yield available to a new buyer. The reverse is also true when market rates fall.
Why are US Treasury yields important?
US Treasuries are widely used as a reference for risk-free or low-credit-risk interest rates in dollar markets. Their yields feed into mortgage rates, corporate borrowing costs, valuation models and currency markets. A large move in Treasury yields can therefore ripple through many asset classes.
Why do growth stocks care about yields?
Many growth companies are valued using expectations for profits years into the future. When the discount rate applied to those future cash flows rises, their present value can fall. This is one reason the Nasdaq can react strongly to rapid moves in Treasury yields.
Why does gold care about real yields?
Gold does not pay a coupon or dividend. When inflation-adjusted yields rise, interest-bearing assets can become relatively more attractive. When real yields fall, the opportunity cost of holding gold can decrease. This is an important relationship, but not a guaranteed trading signal.
What is the yield curve?
The yield curve compares yields on government debt with different maturities. A normal curve often has higher yields for longer maturities. An inverted curve occurs when shorter-term yields exceed longer-term yields and can reflect expectations that monetary policy is restrictive or that future growth will weaken.
Which yields do traders watch?
Common reference points include the 2-year Treasury yield, which can be sensitive to Federal Reserve expectations, and the 10-year yield, which is widely followed across equity, currency and commodity markets. Longer maturities can also matter for financial conditions.
Bottom line
Bond yields are part of the plumbing of financial markets. Understanding them gives traders a better framework for interpreting moves in indexes, currencies and gold instead of viewing each market in isolation.
