Bond Market Questions

Why do bond prices fall when yields rise?

Bond prices fall when market yields rise because an existing bond's fixed cash flows become less attractive relative to newly available bonds. Its price must decline until the return available to a new buyer is competitive with prevailing yields.

Why do bond prices rise when yields fall?

When market yields fall, the fixed cash flows of an existing bond become relatively more attractive. Investors can therefore pay a higher price for those cash flows while still earning a return consistent with the lower market yield.

Can bond prices go above par?

Yes. A bond can trade above par when its coupon and other features are more attractive than those available on comparable new securities.

Why do bonds trade below par?

Bonds trade below par when investors require a return greater than the bond's coupon can provide at a par price, or when credit and liquidity concerns reduce its value.

What is the difference between coupon and yield?

The coupon is the contractual interest payment set by the bond's terms, while yield is the return implied by the bond's current market price and cash flows.

Why is yield to maturity different from coupon rate?

Yield to maturity incorporates the bond's current price, coupon payments and repayment at maturity, while the coupon rate only states the contractual coupon relative to face value.

Why is yield to worst important?

Yield to worst estimates the lowest yield among permitted redemption outcomes, assuming the issuer meets its obligations.

Yields

Why do bond yields rise?

Bond yields can rise because markets expect higher policy rates, stronger growth, higher inflation, greater bond supply, a larger term premium, weaker demand or increased credit risk. The dominant cause depends on which maturity and issuer are moving.

Why do bond yields fall?

Bond yields often fall when investors expect lower policy rates, weaker economic growth, softer inflation or greater demand for safe and liquid assets. Falling yields can also reflect central-bank purchases or declining term and credit premia.

Why are long-term bond yields rising?

Long-term yields can rise because expected future short rates increase, inflation uncertainty grows, the term premium rises, government bond supply expands or investors demand greater compensation for holding duration.

Why are short-term bond yields rising?

Short-term government yields usually rise when markets expect higher central-bank policy rates or expect existing restrictive policy to persist for longer.

Why does term premium matter?

Term premium is the compensation investors require for bearing uncertainty associated with holding long-duration bonds instead of repeatedly investing at short maturities.

What makes term premium rise?

Term premium can rise when uncertainty about inflation, fiscal supply, future rates or bond-market volatility increases and investors demand more compensation for duration.

Can bond yields go negative?

Yes. Bond yields can be negative when investors are willing to pay a price that implies receiving less nominal money than they invest if the bond is held under the assumed cash-flow path.

Why does the Treasury term premium change?

Treasury term premium changes as investors alter the compensation they require for uncertainty around future inflation, rates, supply and duration risk.

Central Banks

Why can bond yields rise after a rate cut?

Longer-term bond yields can rise after a central-bank rate cut if investors conclude that future inflation, growth, government borrowing or the eventual policy path will be stronger than previously expected.

Why does QE lower bond yields?

Quantitative easing can lower bond yields by increasing central-bank demand for securities, removing duration from private portfolios and signaling an easier policy stance.

Why can QT raise bond yields?

Quantitative tightening returns more duration to private investors and can reduce central-bank liquidity, potentially increasing the yield required to absorb bond supply.

How do central banks influence bond yields?

Central banks influence bond yields through policy rates, expected future policy, asset purchases, balance-sheet runoff, liquidity facilities and communication.

Why does forward guidance move markets?

Forward guidance changes the expected future path of policy rates and therefore the discount rates embedded across the yield curve.

What happens when a central bank cuts rates?

A rate cut directly lowers the central bank's policy setting and usually pulls very short-term market rates lower.

What happens when a central bank raises rates?

A rate increase raises short-term financing costs and typically pushes policy-sensitive yields higher if the move was not fully priced.

Why can markets rally after a rate hike?

Markets can rally after a rate hike when the increase was already expected and the accompanying guidance is less restrictive than investors feared.

Why can markets fall after a rate cut?

Markets can fall after a rate cut if investors interpret it as evidence that economic conditions are deteriorating faster than expected or if the future easing path disappoints expectations.

Why do negative interest rates exist?

Negative policy rates have been used when central banks wanted to ease financial conditions beyond a conventional zero lower bound.

How does yield curve control work?

Yield curve control targets a specific government-bond yield or range, with the central bank prepared to buy or sell securities to defend that objective.

Do central banks control long-term bond yields?

Central banks influence long-term yields through expected policy, asset purchases, communication and sometimes explicit yield targets, but long yields also reflect inflation, growth, supply and term premium.

Rates

RATES

What happens to bonds when interest rates rise?

Existing fixed-rate bond prices generally fall when comparable market interest rates rise. The size of the move depends mainly on duration, convexity, credit spreads and the bond's cash-flow structure.

RATES

What happens to bonds when interest rates fall?

Existing fixed-rate bonds generally gain value when comparable market rates fall because their contractual cash flows become more attractive. Long-duration bonds tend to respond more strongly.

Inflation

What happens to bonds during inflation?

Unexpected inflation is usually difficult for nominal bonds because it reduces the purchasing power of fixed cash flows and can lead investors to demand higher yields. Higher required yields push existing bond prices lower.

What happens to bonds during deflation?

Deflation can increase the real purchasing power of fixed nominal bond payments and may lead markets to expect lower policy rates, both of which can support high-quality bond prices.

Why are real yields important?

Real yields measure the return available after accounting for inflation and therefore represent an inflation-adjusted cost of capital.

What makes real yields rise?

Real yields can rise when markets expect tighter monetary policy, stronger real growth, heavier bond supply or a higher real term premium.

What is breakeven inflation telling investors?

Breakeven inflation is the gap between comparable nominal and inflation-linked government bond yields. It reflects expected inflation over the period plus inflation-risk and liquidity effects.

Why do inflation expectations move bond yields?

Investors demand compensation when they expect inflation to erode the purchasing power of future nominal bond payments.

Why do bond markets care about inflation more than stocks sometimes?

Nominal bonds promise fixed cash flows, so unexpected inflation directly reduces their real purchasing power and can increase the yields investors demand.

Why do inflation-linked bonds fall when inflation rises?

Inflation-linked bonds can fall even when inflation rises because their prices also depend on real yields.

What does a falling real yield mean?

A falling real yield means the inflation-adjusted return demanded on government debt has declined.

What does a rising real yield mean?

A rising real yield means investors require a higher inflation-adjusted return on government debt.

Economic Cycle

ECONOMIC CYCLE

What happens to bonds in a recession?

High-quality government bonds often benefit during recessions when markets expect lower inflation and monetary easing, but corporate bonds can face wider credit spreads as default risk rises.

ECONOMIC CYCLE

Are bonds safe during a recession?

No bond is universally safe during a recession. High-quality sovereign debt may benefit from falling rates and demand for liquidity, while lower-quality corporate and emerging-market debt can lose value as credit spreads widen.

Yield Curve

Why does the yield curve invert?

A yield curve commonly inverts when short-term rates are high because of restrictive monetary policy while investors expect weaker growth, lower inflation and lower policy rates later.

What does an inverted yield curve mean?

An inverted yield curve means yields on shorter maturities exceed yields on longer maturities across a relevant part of the curve.

Why does the yield curve steepen?

The yield curve steepens when the gap between long- and short-term yields increases. This can happen because short yields fall faster, long yields rise faster, or both.

Why does the yield curve flatten?

The yield curve flattens when the difference between long- and short-term yields narrows. Tightening expectations can lift short yields faster than long yields, while growth concerns can restrain the long end.

What is a bull steepener?

A bull steepener occurs when yields fall and shorter-maturity yields fall more than longer-maturity yields, causing the curve to steepen.

What is a bear steepener?

A bear steepener occurs when yields rise and longer-maturity yields rise more than shorter-maturity yields.

What is a bull flattener?

A bull flattener occurs when yields fall while longer-maturity yields decline more than shorter-maturity yields.

What is a bear flattener?

A bear flattener occurs when yields rise while shorter-maturity yields rise more than longer-maturity yields.

What does the 2s10s spread mean?

The 2s10s spread is the ten-year Treasury yield minus the two-year Treasury yield. It summarizes the slope between a policy-sensitive maturity and a major long-term benchmark.

What does the 3m10y spread mean?

The 3m10y spread compares the ten-year Treasury yield with a very short three-month rate.

Why can the yield curve uninvert before a recession?

A curve can steepen out of inversion when short-term yields begin falling rapidly as markets price policy easing in response to weaker economic conditions.

Sovereign Debt

Why do Treasury yields matter?

U.S. Treasury yields are reference rates for a large part of global finance. They influence borrowing costs, discount rates, mortgage pricing, corporate bonds and the valuation of many risk assets.

Can government bonds lose money?

Yes. Government bonds can decline in market value when yields rise, and sovereign bonds can also carry inflation, currency, liquidity and in some cases credit risk.

Can government bonds default?

Yes. Sovereign governments can default, restructure debt or alter payment terms, particularly when borrowing in a currency they cannot freely create or when fiscal and political constraints become severe.

Why do sovereign bond spreads widen?

Sovereign spreads widen when investors demand more compensation relative to a benchmark because of rising fiscal, political, liquidity, currency or redenomination risk.

Why does government debt affect bond yields?

Government debt can affect yields through expected issuance, fiscal sustainability, inflation risk, economic policy and the amount of duration the private market must absorb.

Why does bond supply affect yields?

When the market must absorb more bonds, prices may need to adjust to attract sufficient demand. All else equal, that can mean lower prices and higher yields.

What is refinancing risk?

Refinancing risk is the possibility that maturing debt must be replaced at materially higher rates or under difficult market conditions.

Why does a debt maturity wall matter?

A debt maturity wall concentrates refinancing needs into a relatively short period, increasing exposure to prevailing market rates and investor demand at that time.

What is redenomination risk?

Redenomination risk is the possibility that a debt obligation is converted into a different currency, often in the context of stress within a currency union or a change in monetary regime.

Why does the maturity profile matter for debt?

The maturity profile determines when an issuer must repay or refinance principal and therefore how quickly current market rates feed into financing costs.

Why do foreign investors buy government bonds?

Foreign investors buy government bonds for reserve management, yield, liquidity, diversification, regulatory needs and currency exposure.

Cross Asset

Why do Treasury yields affect stocks?

Treasury yields affect stocks because they influence discount rates, financing costs and the return investors can earn on lower-risk assets.

Why do bond yields affect mortgage rates?

Mortgage rates are influenced by the broader interest-rate curve because mortgage lenders and investors compare mortgage cash flows with government bonds and other fixed-income assets.

Why do bond yields affect currencies?

Bond yields influence currencies because interest-rate differences affect the relative return available on assets denominated in different currencies.

Why do bond yields affect gold?

Bond yields, especially real yields, affect the opportunity cost of holding gold because gold does not pay a contractual coupon.

Why do oil prices affect bond yields?

Oil prices can affect bond yields through inflation expectations, household purchasing power, corporate investment and economic growth.

Why does the dollar affect bond markets?

The U.S. dollar affects global bond markets through funding costs, capital flows, commodity pricing and the burden of dollar-denominated debt.

Why do stocks and bonds sometimes fall together?

Stocks and bonds can fall together when the dominant shock is higher inflation or higher real discount rates rather than weaker growth.

Why do stocks rise when bond yields fall?

Stocks can rise when bond yields fall because lower discount rates increase the present value of future corporate cash flows and reduce financing costs.

Why do stocks fall when bond yields rise?

Higher bond yields can pressure equities by increasing discount rates, raising borrowing costs and offering investors a more attractive lower-risk alternative.

Why does hedging cost matter for foreign bond investors?

A foreign investor's return depends not only on the bond yield but also on the cost of hedging currency exposure.

Duration & Risk

Why does duration matter?

Duration translates a change in yield into an approximate percentage change in bond price, making it one of the central measures of fixed-income interest-rate risk.

Why do long-duration bonds move more?

Long-duration bonds move more because a larger share of their value comes from cash flows received further in the future, whose present values are more sensitive to changes in discount rates.

Can a short-term bond lose money?

Yes. Short-term bonds can lose value if yields rise, credit quality deteriorates, liquidity worsens or the issuer defaults.

Why does convexity matter?

Convexity captures the curvature in the relationship between bond prices and yields that a simple duration estimate misses.

What is negative convexity?

Negative convexity occurs when a bond's expected cash flows change in a way that limits price gains as yields fall or increases sensitivity in unfavorable directions.

Why does DV01 matter?

DV01 expresses the approximate monetary change in value for a one-basis-point move in yield.

What is reinvestment risk?

Reinvestment risk is the possibility that coupons or returned principal must be reinvested at lower rates than were previously available.

Credit

Why do credit spreads widen?

Credit spreads widen when investors demand greater compensation for default risk, downgrade risk, liquidity risk or uncertainty.

Why do credit spreads tighten?

Credit spreads tighten when investors require less extra yield over safer benchmarks, often because growth expectations improve, default risk falls or demand for credit strengthens.

What happens to corporate bonds in a recession?

Corporate bonds can face wider credit spreads during recessions because weaker revenues and tighter financing conditions increase perceived default and downgrade risk.

Why do high-yield bonds behave like stocks?

High-yield bonds often behave more like equities than government bonds because their prices are strongly influenced by corporate earnings, default risk and investor risk appetite.

Why do ratings affect bond yields?

Credit ratings influence how investors classify default risk and can affect index eligibility, mandates, collateral rules and regulatory treatment.

What happens when a bond is downgraded?

A downgrade can widen a bond's credit spread and lower its price if investors demand greater compensation for risk.

What is a fallen angel bond?

A fallen angel is a bond that was issued with an investment-grade rating but was later downgraded into high yield.

Why do defaults rise when rates stay high?

Persistently high rates increase refinancing costs and interest expense, especially for borrowers whose low-cost debt matures and must be replaced.

Market Structure

Why do bond ETFs trade differently from bonds?

Bond ETFs trade continuously on exchanges while many underlying bonds trade over the counter and sometimes infrequently.

Can a bond ETF lose money when rates fall?

Yes. Falling benchmark rates can be outweighed by widening credit spreads, currency losses, fees or changes in the portfolio's composition.

Why does bond liquidity disappear?

Bond liquidity can deteriorate when dealers reduce balance-sheet capacity, investors rush to sell similar positions, volatility rises or reliable pricing becomes difficult.

Why do bid-ask spreads widen?

Bid-ask spreads widen when market makers face greater uncertainty, inventory risk or difficulty hedging a position.

Why is liquidity important in fixed income?

Liquidity determines how easily an investor can trade a bond without materially moving its price.

Why are some bonds hard to trade?

Some bonds trade infrequently because an issuer has many separate securities, the issue size is small, investors hold the bonds to maturity or dealer inventories are limited.

What is price discovery in bond markets?

Price discovery is the process through which buyers and sellers incorporate new information into executable market prices.

Market Signals

What is the bond market signaling?

The bond market can signal expectations about growth, inflation, monetary policy, credit risk and liquidity through the level and shape of yields and spreads.

Can the bond market predict recessions?

Parts of the yield curve have historically contained information about future economic slowdowns, but bond markets do not predict recessions with certainty.

Why does the 2-year Treasury yield matter?

The two-year Treasury yield is closely tied to expectations for the Federal Reserve policy path over the next several years.

Why does the 10-year Treasury yield matter?

The ten-year Treasury yield is a global benchmark that combines expectations for future short-term rates with term premium and long-run macro uncertainty.

Why does the 30-year Treasury yield matter?

The thirty-year Treasury yield reflects very long-run expectations and compensation for duration, inflation and supply risk.

Why do bond yields move before economic data?

Bond yields can move before official data because markets continuously price forecasts, surveys, positioning and new information about the economy.

Market Plumbing

Why does repo matter to bond markets?

Repo allows securities dealers and investors to finance bond positions using securities as collateral. It is therefore a core funding mechanism behind government-bond market liquidity.

Why do repo rates spike?

Repo rates can spike when demand for cash exceeds available funding, reserves are unevenly distributed, balance-sheet capacity is constrained or collateral flows create temporary pressure.

What happens when collateral becomes scarce?

When a particular high-quality security becomes scarce, borrowers may accept unusually low repo rates to obtain it, and the security can trade 'special' in financing markets.

Why are Treasury securities used as collateral?

Treasuries are widely used as collateral because they are highly standardized, actively traded and generally viewed as carrying low credit risk in U.S. dollars.

Why does settlement matter in bond markets?

Settlement is when securities and cash are actually exchanged after a trade. Failures or delays can create counterparty, funding and operational risk even when the trade price itself is agreed.

What is a settlement fail?

A settlement fail occurs when securities or cash are not delivered as required on the scheduled settlement date.

Auctions & Supply

What happens when a bond auction is weak?

A weak bond auction can force the issuer to offer a higher yield to attract buyers and may pressure nearby maturities in the secondary market.

What does a high bid-to-cover ratio mean?

A high bid-to-cover ratio means submitted bids were large relative to the amount of securities offered.

Why do Treasury auctions move yields?

Treasury auctions reveal the yield required for investors to absorb new government debt at a specific maturity.

What is a tail in a bond auction?

An auction is commonly described as tailing when the awarded yield is higher than the yield indicated in the market immediately before the auction.

What is a stop-through in a bond auction?

An auction is described as stopping through when the awarded yield is lower than the comparable pre-auction market yield.

Economic Data

Why does CPI move bond yields?

CPI can move bond yields because inflation affects the expected path of central-bank policy and the real value of nominal fixed payments.

Why does the jobs report move bond yields?

Employment data influence expectations for economic growth, wage pressure, inflation and central-bank policy.

Why does GDP move bond yields?

GDP data can affect bond yields by changing expectations for growth, inflation and future monetary policy.

Why do PMIs move bond markets?

Purchasing managers' surveys can move bonds because they provide relatively timely information about business activity, orders, employment and prices.

Safe Havens

Why do bonds rally during market panic?

High-quality government bonds can rally during market panic as investors seek liquidity and safety while pricing weaker growth and future monetary easing.

Are Treasuries always a safe haven?

No. Treasuries are widely treated as high-quality liquid assets, but their market prices remain exposed to interest-rate, inflation and liquidity risk.

Why can safe-haven bonds sell off in a crisis?

Safe-haven bonds can sell off when investors urgently need cash, leveraged positions are unwound or inflation and fiscal concerns dominate the shock.

What is flight to quality?

Flight to quality describes a shift from riskier assets toward securities perceived as safer or more liquid during periods of uncertainty.

Bond Structure

Why do callable bonds behave differently?

Callable bonds give the issuer the right to redeem debt early, which changes the investor's expected cash flows when rates move.

Why do floating-rate bonds have less duration risk?

Floating-rate bond coupons reset periodically with a reference rate, so their income adjusts more quickly to changes in short-term rates.

Why do zero-coupon bonds have high duration?

A zero-coupon bond makes no interim coupon payments, so all contractual cash flow arrives at maturity.

What happens to a bond as it approaches maturity?

If credit conditions remain stable and the issuer is expected to repay at par, a bond's price tends to converge toward its redemption value as maturity approaches.

Benchmarks

BENCHMARKS

Why did markets move from LIBOR to SOFR?

Markets moved away from LIBOR after concerns about the robustness and integrity of a benchmark that relied partly on bank submissions in markets with declining underlying transactions.

BENCHMARKS

What is the difference between SOFR and LIBOR?

SOFR is an overnight secured rate based on U.S. Treasury repo transactions, while LIBOR historically represented unsecured bank borrowing rates across multiple terms and currencies.

BENCHMARKS

Why do benchmark rates matter?

Benchmark rates provide common reference points for pricing loans, bonds, derivatives and other contracts.

Emerging Markets

EMERGING MARKETS

Why do emerging-market bond yields rise?

Emerging-market yields can rise because of domestic inflation, tighter policy, fiscal concerns, currency weakness, global risk aversion or higher U.S. yields.

EMERGING MARKETS

Why does a stronger dollar hurt emerging-market debt?

A stronger dollar can tighten financial conditions for borrowers with dollar-denominated liabilities because local-currency revenues buy fewer dollars needed for debt service.

Institutional Investors

Why do pension funds buy long-term bonds?

Pension funds often hold long-duration bonds because their liabilities extend many years into the future.

Why do insurers buy bonds?

Insurers receive premiums today and must meet future claims, making predictable fixed-income cash flows useful for matching liabilities.

Why do banks hold government bonds?

Banks hold government bonds for liquidity management, collateral, regulatory requirements, interest income and balance-sheet positioning.

Why do central banks hold foreign government bonds?

Central banks hold foreign government bonds as part of official reserve portfolios used for liquidity, intervention capacity and confidence in external payments.

Derivatives

Why do bond futures matter?

Bond futures provide a liquid way to adjust duration exposure, hedge portfolios and express views on government yields without trading every underlying cash bond.

What is the bond basis?

The bond basis is the relative price relationship between a cash bond and a related futures contract after accounting for financing, delivery and conversion terms.

Why do swaps matter to bond markets?

Interest-rate swaps allow investors to exchange fixed and floating rate exposures without buying or selling the underlying government bond.

Why do swap spreads move?

Swap spreads move because government-bond supply, bank balance-sheet costs, repo conditions, derivatives demand and credit factors change relative pricing between swaps and sovereign bonds.

Market Basics

MARKET BASICS

Why is the bond market important for the economy?

The bond market determines financing costs for governments, companies and households and transmits monetary policy into the real economy.

MARKET BASICS

Is the bond market bigger than the stock market?

Global bond markets are enormous and include sovereign, agency, corporate, securitized and other debt, but comparisons with equities depend on the dataset, date and definition used.

MARKET BASICS

Who sets bond yields?

Market yields are set through trading between buyers and sellers, while central banks directly set or target only specific policy rates and can influence broader yields.

Fiscal Policy

Why do bond markets react to fiscal policy?

Fiscal policy can change expected government borrowing, growth, inflation and the perceived sustainability of public finances.

Why can tax cuts raise bond yields?

Tax cuts can raise bond yields when investors expect stronger demand, higher inflation, larger deficits or increased government issuance.

Why can government spending raise bond yields?

Additional government spending can lift yields if markets expect stronger growth, higher inflation or more bond issuance.

What is fiscal dominance?

Fiscal dominance describes a situation in which monetary policy becomes constrained by the government's fiscal position or financing needs.

Why does debt service cost matter?

Debt service cost determines how much government or corporate cash flow is absorbed by interest payments.

Global Markets

Why do bond yields move overnight?

Major sovereign bonds trade across global time zones, and futures, currencies and related markets continue incorporating information outside local cash-market hours.

Why do global bond yields move together?

Global yields often move together because major economies share inflation shocks, growth cycles, capital flows and expectations about central-bank policy.

Why do Japanese bond yields matter globally?

Japanese yields matter because Japan has a large sovereign bond market and Japanese institutions are major global investors.

Why do German Bund yields matter?

German Bunds are a central reference for euro-area interest rates and are widely used as high-quality collateral and a benchmark for sovereign spreads.

Why do Italian bond spreads matter?

Italian government-bond spreads versus German Bunds are closely watched as a gauge of euro-area sovereign risk, fiscal concerns and fragmentation.

What is financial fragmentation in bond markets?

Financial fragmentation occurs when borrowers or markets within an integrated financial area face materially different financing conditions for reasons that impair uniform policy transmission.

Financial System

Why do bond markets matter for banks?

Banks hold bonds, use them as collateral, price loans from market rates and fund themselves through debt markets.

Why do higher yields hurt bank bond portfolios?

Higher yields reduce the market value of existing fixed-rate bonds held by banks.

Why is collateral important to financial stability?

Collateral supports secured borrowing, derivatives margin and liquidity management throughout the financial system.
