Bond Trading Strategies Guide

At a glance

Core relationship: Yields up means prices down, amplified by duration
Main return sources: Carry, roll-down, duration, and credit spread
Access: Treasury futures, bond ETFs, individual bonds
Best strategies: Curve trades, carry, trend on rates futures

Key takeaways

Duration converts a yield change into a price change: a bond with duration 8 falls roughly 8 percent when yields rise one percentage point.
The yield curve is tradeable in its own right: steepeners and flatteners isolate the relationship between maturities rather than the level of rates.
Carry and roll-down provide a return even when yields are unchanged, and are the main reason longer bonds are held in normal curve conditions.
Credit spread strategies are short-volatility in shape: steady income, occasional sharp losses when default risk reprices.
Treasury futures are the cleanest retail access to rates, with deep liquidity and standardised duration exposure.

Price, yield, and duration

A bond pays fixed coupons and returns principal at maturity. Its price moves inversely to its yield, because the fixed payments become more or less attractive as market rates change. Duration measures how sensitive the price is to yield changes, expressed in years.

Approximate price change = -Duration x change in yield

Bond with duration 8.0, yields rise from 4.00% to 4.50%:
   Price change = -8.0 x 0.50% = -4.0%

Bond with duration 2.0, same yield move:
   Price change = -2.0 x 0.50% = -1.0%

Convexity adjusts this for large moves: prices fall slightly
less than the linear estimate when yields rise, and rise
slightly more when yields fall.

The relationship you need before anything else.

This single formula explains the large losses in long-duration bond funds during rapid rate increases. A 30-year treasury fund with duration near 17 can lose more than 30 percent when yields rise two percentage points, which is a magnitude most investors associate with equities rather than with government bonds.

Where bond returns come from

Source	Mechanism	When it dominates
Carry (coupon income)	Interest accrues regardless of price	Stable rate environments
Roll-down	As a bond ages it moves down an upward-sloping curve, gaining price	Steep curves
Duration (rate moves)	Price gains when yields fall	Policy easing cycles, recessions
Credit spread	Compensation for default risk narrowing	Recoveries and risk-on periods
Currency	For foreign bonds, unhedged exposure	Often dominates the bond return entirely

The practical consequence: a bond position is several bets at once. Buying a foreign high-yield bond fund is simultaneously a rates bet, a credit bet, and a currency bet, and the currency component frequently has the largest variance of the three.

Yield curve strategies

The curve plots yields across maturities. Its shape reflects policy expectations, term premium, and supply and demand at different maturities, and its changes can be traded independently of the level of rates.

Steepener: Long shorter maturities, short longer maturities. Profits when long yields rise relative to short yields, typically when policy is easing or term premium is rising.
Flattener: The reverse. Profits when short yields rise relative to long yields, typically during tightening cycles.
Butterfly: A position in three maturities expressing a view on the curvature rather than the slope, for example long the wings and short the belly.
Duration-neutral construction: Legs are sized so that the position has minimal exposure to a parallel shift in rates, isolating the shape change.
Inversion: When short yields exceed long yields. Historically associated with subsequent economic slowdowns, though the lead time has varied enormously.

How to access rates markets

Instrument	Exposure	Pros	Cons
Treasury futures (ZT, ZF, ZN, ZB)	Duration at standardised points	Deep liquidity, low margin, easy shorts	Contract rolls; notional is large
Government bond ETFs	Duration, unleveraged	Simple, accessible	Fixed duration profile; expense ratio
Individual bonds	Specific maturity and issuer	Known cash flows and maturity date	Wide dealer spreads for retail; poor liquidity
Corporate and high-yield ETFs	Credit plus duration	Income; accessible	Credit risk; liquidity mismatch in stress
Inflation-protected bonds	Real yields	Direct exposure to real rates	Complex tax treatment; illiquid in some markets
Interest rate swaps and options	Precise rate exposure	Institutional flexibility	Not accessible to retail

Practical bond strategies

Trend following on rates futures. Bond markets trend as policy cycles develop, and rates futures are a standard component of diversified trend following portfolios.
Carry and roll-down selection. Hold the maturity with the best combination of yield and roll-down for a given duration, rather than simply buying the longest bond.
Curve positioning around policy expectations. Steepeners and flatteners expressed with duration-neutral futures spreads.
Credit spread trades. Long credit versus short duration-matched treasuries isolates the spread. This has an insurance-like payoff and should be sized accordingly.
Laddering for income. Holding bonds across staggered maturities reduces reinvestment risk and provides predictable cash flows. It is an investment approach rather than a trading strategy.
Duration overlay for a portfolio. Using treasury futures to adjust the overall duration of a portfolio without selling the underlying holdings.

Risks that surprise people

Bonds are not automatically safe. Long-duration government bonds have produced equity-sized drawdowns during rapid rate increases.
The equity-bond correlation is not stable. It has been negative in some decades and positive in others, particularly when inflation is the dominant driver. Portfolio construction that assumes the negative relationship can fail exactly when needed.
Credit liquidity is illusory in stress. Corporate and high-yield ETFs trade continuously while the underlying bonds do not, which is why discounts to stated value appear during stress.
Futures notional is large. One 10-year note contract represents roughly 110,000 USD of exposure, so position sizing must account for duration-adjusted risk rather than contract count.
Reinvestment risk. Rolling short bonds in a falling rate environment means reinvesting at successively lower yields, which is the mirror image of duration risk.

Frequently asked questions

Why do bond prices fall when interest rates rise?

Because a bond pays fixed coupons. If newly issued bonds pay a higher rate, an existing bond paying less is worth correspondingly less, and the price falls until its yield matches the market. Duration measures how large that price adjustment is for a given change in yield.

Are bonds a safe investment?

Government bonds carry minimal default risk in major currencies, but they carry substantial price risk if held before maturity, particularly at long maturities. Holding an individual bond to maturity returns the principal regardless of interim price moves; a bond fund has no maturity date, so the price risk is permanent.

What does an inverted yield curve mean?

It means short-term yields exceed long-term yields, which typically reflects expectations that policy rates will fall. Historically it has preceded economic slowdowns, but the lead time has varied from months to years, which makes it a poor trading signal despite being a widely watched indicator.

How can I trade bonds with a small account?

Bond ETFs offer duration exposure with fractional-share sizing. Treasury futures are more capital efficient but have large notional values, so the shorter-maturity contracts are more suitable for smaller accounts. Individual bonds are generally poor for retail traders because dealer spreads are wide and liquidity is limited.

What is roll-down return?

On an upward-sloping curve, as a bond ages its remaining maturity shortens and it is valued at a lower yield, which raises its price. That gain occurs even if the curve does not move at all. Roll-down plus coupon income is the carry of a bond position and is a significant part of expected return in steep curve environments.
