M5: Fixed-Income Markets for Government Issuers

What are the four main types of public-sector fixed-income issuers?

Sovereign governments; non-sovereign governments; quasi-government agencies; supranational organizations.

What is a sovereign issuer?

A national government with the legal authority to tax economic activity and issue debt.

What is the primary source of repayment for sovereign debt?

National tax revenues.

Why do developed-market sovereigns generally have the lowest default risk in their domestic market?

They have broad taxation powers and, for domestic-currency debt, control over currency issuance.

What determines the level of sovereign government debt?

Fiscal policy, particularly government spending and tax-revenue decisions.

What does government debt management determine?

The composition of sovereign debt, including maturity, fixed versus floating rates, and currency denomination.

What are Treasury bills?

Short-term sovereign securities with maturities of one year or less, typically issued as zero-coupon instruments at a discount.

What are US Treasury notes?

US Treasury securities with original maturities from 2 through 10 years.

What are US Treasury bonds?

US Treasury securities with original maturities greater than 10 years, commonly 20 or 30 years.

What is the key US Treasury maturity boundary between notes and bonds?

10 years: 2–10 years = notes; greater than 10 years = bonds.

What types of medium- and long-term securities can sovereigns issue?

Fixed-rate, floating-rate, inflation-linked, and foreign-currency securities.

How do developed-market and emerging-market sovereigns generally differ in funding access?

DM sovereigns typically access the full maturity spectrum; EM sovereigns may have more limited long-term access, particularly in domestic currency.

What is domestic debt for an emerging-market sovereign?

Debt issued in the sovereign's domestic currency, often held mainly by domestic financial institutions.

What is external debt for an emerging-market sovereign?

Debt denominated in a foreign currency and often held by foreign investors or supranational institutions.

Why is external debt riskier for an emerging-market sovereign?

The sovereign must obtain foreign currency to service the debt and cannot simply issue that foreign currency itself.

Does an investor holding an EM sovereign bond denominated in the investor's own currency face direct currency risk on the promised cash flows?

No, but the investor faces indirect currency-related credit risk because the issuer must obtain foreign currency to repay the bond.

What is rollover risk for a government?

The risk that maturing debt must be refinanced at higher rates or during unfavorable market conditions.

Why don't governments simply issue all debt at the shortest possible maturity to minimize interest costs?

Doing so would create excessive rollover risk.

How do governments manage the trade-off between funding cost and rollover risk?

They distribute debt issuance across different maturities and issue at regular, predictable intervals.

What does Ricardian equivalence suggest under its strict assumptions?

Governments should be indifferent between current taxation and borrowing because taxpayers anticipate future taxes and adjust saving accordingly.

Why does Ricardian equivalence not eliminate sovereign debt-management concerns in practice?

Its assumptions do not fully hold, and excessive short-term borrowing creates real rollover risk.

Why do sovereign governments issue debt across the full maturity spectrum?

To create benchmark yields, facilitate interest-rate hedging, provide high-quality collateral, support monetary policy, and provide reserve assets.

Why are sovereign yields important benchmarks?

They provide reference discount rates for pricing other domestic-currency fixed-income securities.

Why are sovereign securities widely used as repo and derivatives collateral?

They generally have high liquidity and low credit risk.

What is a non-sovereign government issuer?

A sub-national government such as a state, province, municipality, or other regional authority.

What are the two major types of non-sovereign government bonds?

General obligation (GO) bonds and revenue bonds.

What is a general obligation (GO) bond?

A non-sovereign government bond repaid from the issuer's general taxing power.

What is the primary repayment source for a GO bond?

Local or regional tax revenues.

What does the credit quality of a GO bond primarily depend on?

The overall fiscal health and taxing capacity of the government issuer.

What is a revenue bond?

A bond issued to finance a specific project and repaid primarily from the project's revenues.

What are typical sources of repayment for revenue bonds?

Tolls, user fees, lease payments, or other revenues generated by the financed project.

What does the credit quality of a revenue bond primarily depend on?

The economic viability and cash flows of the underlying project.

What is the key exam distinction between GO and revenue bonds?

GO = general tax revenues; revenue bond = cash flows from a specific project.

Why are revenue bonds often long-dated?

Their maturities are typically matched to the long economic lives and cash flows of the projects they finance.

What is a quasi-government agency?

An entity authorized by government to provide a specific public good or service and that finances itself partly through debt issuance.

What is usually the primary repayment source for quasi-government agency debt?

Cash flows generated by the agency's underlying activities.

What may provide a secondary source of support for quasi-government debt?

An implicit or explicit sovereign-government guarantee.

How do quasi-government borrowing costs generally compare with sovereign borrowing costs?

They are often close to sovereign yields but may be higher because agency debt lacks the full liquidity advantage of sovereign debt.

What is an important pricing difference between sovereign and quasi-government debt?

The credit-quality difference may be small, while the liquidity difference can be more significant.

What is a supranational organization?

An organization created and supported by multiple sovereign governments to pursue shared economic or social objectives.

What are common purposes of supranational organizations?

Economic development, trade promotion, infrastructure financing, and financing emerging economies.

What are important sources of repayment and support for supranational debt?

Operating/lending income and member-state support, including callable capital.

What is callable capital in the context of a supranational?

Capital that member governments have committed to provide if required.

What is the typical credit quality of major supranational issuers?

Very high, often AAA.

Why can supranational issuers have extremely high credit quality?

They benefit from diversified member-state support, callable capital, and generally prudent lending practices.

What are the three dimensions that can simultaneously classify a fixed-income security?

Geography, issuer type, and tax status.

What is a domestic bond?

A bond issued in the local market by a local issuer.

What is a foreign bond?

A bond issued in a local market by a foreign issuer.

What is a Yankee bond?

A foreign bond issued in the US market by a foreign issuer.

What is a Bulldog bond?

A foreign bond issued in the UK market by a foreign issuer.

What is a Eurobond?

A bond issued in a currency different from the local currency of the market where it is sold.

What are the major issuer-type classifications for fixed-income securities?

Government/sovereign; quasi-government; corporate; structured finance.

How can fixed-income securities be classified by tax status?

Tax-exempt, taxable, or tax-deferred.

What is the key exam approach when classifying a bond across multiple dimensions?

Ask separately: Where is it issued? Who issued it? How is it taxed?

What is the main issuance method used by sovereign governments?

Scheduled public auctions managed by the national treasury or finance ministry.

What is the main issuance method used by corporations?

Opportunistic issuance managed through investment-bank underwriters.

How does sovereign issuance timing differ from corporate issuance timing?

Sovereign issuance is generally regular and calendar-driven; corporate issuance is more opportunistic and market-driven.

How does price discovery differ between sovereign and corporate primary markets?

Sovereigns typically use competitive auctions; corporations typically use bookbuilding by underwriters.

What are the two main types of sovereign auction bids?

Competitive and non-competitive bids.

What is a competitive bid in a sovereign auction?

A bid specifying both the quantity desired and an acceptable price or yield.

What happens to a competitive bidder whose requested yield is above the auction's cut-off yield?

The bidder receives no securities.

What is a non-competitive bid?

A bid in which the investor accepts the auction-determined price and receives the requested quantity, subject to applicable limits.

What is the advantage of a non-competitive bid to the investor?

Allocation is assured, subject to the permitted quantity cap.

How are competitive bids ranked in a sovereign auction?

From highest price/lowest yield to lowest price/highest yield.

What is the stop-out or cut-off yield?

The highest accepted yield, corresponding to the lowest price necessary to sell the required amount.

What is a single-price (uniform-price) auction?

All successful bidders pay the same stop-out price regardless of their individual winning bids.

What is a multiple-price (discriminatory) auction?

Each successful bidder pays the price corresponding to their own bid.

What is the key difference between single-price and multiple-price auctions?

Single-price = all winners pay the cut-off price; multiple-price = each winner pays their own bid price.

Does bid ranking differ between single-price and multiple-price auctions?

No. Both rank bids from highest price/lowest yield downward.

Why may single-price auctions encourage more aggressive bidding?

Winners do not have to pay their own higher bid prices; all winners pay the common stop-out price.

What is the winner's curse in a multiple-price auction?

An aggressive bidder may win but pay an unusually high price based on their own bid.

What are the four basic phases of a single-price sovereign auction?

Announcement → bidding → allocation → settlement.

What happens to non-competitive bids during allocation?

They are accepted first, subject to applicable limits.

What happens after non-competitive bids are allocated?

Competitive bids are ranked from lowest yield upward until the remaining issue amount is filled.

What is the bid-to-cover ratio?

Total bids received ÷ total securities offered/allotted.

What does a higher bid-to-cover ratio generally indicate?

Stronger demand for the sovereign issue.

Who are primary dealers?

Designated financial intermediaries that participate in sovereign auctions and help support government debt markets.

What are important functions of primary dealers?

Participate in auctions, act as central-bank counterparties, facilitate investor transactions, and make secondary markets in sovereign debt.

Are primary dealers generally required to participate in sovereign auctions?

Yes, they are typically required to submit competitive bids in auctions.

Where does most sovereign debt trade after issuance?

Over the counter (OTC) through broker/dealer intermediaries.

Where does most corporate debt trade after issuance?

Also primarily OTC.

What is an on-the-run sovereign security?

The most recently issued sovereign security at a particular benchmark maturity.

What is an off-the-run sovereign security?

A previously issued security of the same or similar maturity that has been replaced by a newer benchmark issue.

Which is generally more liquid: on-the-run or off-the-run sovereign debt?

On-the-run sovereign debt.

How do bid-ask spreads compare for on-the-run and off-the-run sovereign securities?

On-the-run securities generally have tighter spreads; off-the-run securities have wider spreads.

How do yields generally compare between otherwise similar on-the-run and off-the-run securities?

On-the-run securities generally have slightly lower yields because of their greater liquidity.

Why does an on-the-run security usually trade at a higher price and lower yield?

Investors value its greater liquidity and are willing to accept a lower yield.

What happens when a new benchmark sovereign bond is issued?

The previous on-the-run issue becomes off-the-run and typically loses some of its liquidity premium.

Which sovereign securities are commonly used as benchmark yields?

On-the-run securities.

How do repo rates generally compare for on-the-run and off-the-run sovereign securities?

On-the-run securities typically have lower repo rates because they are more desirable collateral.

What does it mean when an on-the-run security goes "on special" in the repo market?

Strong demand for that specific collateral pushes its repo rate below the general collateral repo rate.

Who are examples of non-economic buyers of sovereign debt?

Central banks, foreign central banks, governments, banks, and insurers holding securities for policy, reserve, regulatory, or liquidity purposes.

Why are some sovereign-debt investors described as non-economic?

Their purchases may be driven by monetary policy, reserve management, or regulation rather than purely by maximizing investment return.

How can non-economic demand affect sovereign borrowing costs?

It increases demand for sovereign securities and can reduce government borrowing costs.

What is a reserve currency?

A currency widely held by central banks as foreign-exchange reserves and widely used in international trade and finance.

Why can issuing debt in a reserve currency benefit a sovereign?

Global reserve demand can increase demand for its securities and lower its funding cost.

Who manages sovereign issuance versus corporate issuance?

Sovereign = national treasury/finance ministry; corporate = investment-bank underwriters.

What determines sovereign versus corporate issuance timing?

Sovereign = scheduled and regular; corporate = opportunistic and market-driven.

What determines primary-market pricing for sovereign versus corporate bonds?

Sovereign = auction bidding; corporate = underwriter-led bookbuilding.

What is the typical distribution channel for sovereign debt?

Primary dealers and, in some markets, direct investor participation.
