What it means
Historically a company raising debt abroad had to choose a market: a domestic issue at home, a foreign bond sold in one overseas market, or a eurobond sold outside any single jurisdiction. A global bond collapses that choice by being offered across several of these channels at the same time, under documentation and clearing arrangements that let all of them settle.
The commercial logic is straightforward supply and demand. A $2 billion issue that can only be bought by domestic institutions may have to pay up to clear, whereas the same issue open to buyers on three continents attracts more orders, and more orders normally means a tighter spread over the government benchmark.
Global bonds are usually the preserve of large, well-rated issuers. Sovereign governments, development banks and household-name corporates dominate the market, because the legal, listing and clearing work only pays for itself on a deal large enough to spread those fixed costs thinly.
Currency is the detail that trips people up. A global bond is denominated in one currency even though it is sold worldwide, so an investor buying a dollar-denominated global bond outside the United States carries the exchange rate risk unless they hedge it separately.
For a finance team, the practical trade-off is reach against complexity. You gain access to a deeper investor base and often a lower coupon, but you take on multi-jurisdiction disclosure, additional legal opinions and the ongoing obligation to keep investors in several time zones informed.
In practice
Real-world examples.
Example
A national government issues a $3 billion ten-year global bond to fund infrastructure, marketing it in Asia, Europe and North America over three days of investor meetings. Demand reaches roughly four times the deal size, which lets the treasury price 15 basis points tighter than it had budgeted.
Example
A multinational drinks group refinances bank debt with a $1.5 billion global bond in two tranches, a five-year and a ten-year. Because the same security settles through several clearing systems, index funds in three regions can hold it, which supports its price in secondary trading.
Example
A supranational development bank issues a $750 million global bond aimed partly at retail investors in one market and partly at central bank reserve managers in another. The treasurer values the diversification of the buyer base as much as the pricing, because it means the bank is not dependent on one region's appetite the next time it needs funding.
Formula
Calculation
Net proceeds = Face value x Issue price as a percentage of par.
Current yield = Annual coupon cash / Net proceeds.
Approximate yield to maturity = [Annual coupon + (Face value - Net proceeds) / Years to maturity] / [(Face value + Net proceeds) / 2].
A development bank issues a $500,000,000 five-year global bond with a 4.5% annual coupon, priced at 98.50 per 100 of face value.
Net proceeds = $500,000,000 x 0.9850 = $492,500,000.
Annual coupon cash = $500,000,000 x 4.5% = $22,500,000.
Current yield = $22,500,000 / $492,500,000 = 4.57%.
Approximate yield to maturity = [$22,500,000 + ($500,000,000 - $492,500,000) / 5] / [($500,000,000 + $492,500,000) / 2] = ($22,500,000 + $1,500,000) / $496,250,000 = $24,000,000 / $496,250,000 = 4.84%.
The issuer pays a 4.5% coupon but the true cost is closer to 4.84% a year once the discount to par is spread across the five-year life.Case study
Seen in the real world.
Meridian Utilities Group is a fictional, illustrative energy network operator that needed $1.2 billion to refinance maturing debt and fund grid upgrades. Its previous three issues had all been domestic, and each time the same twenty or so institutions had taken almost the entire book, which gave those buyers considerable pricing power.
For this deal the illustrative treasury team chose a global bond structure, running a marketing programme across three regions and arranging clearing so that overseas institutions could settle the security exactly as they would a local one. The order book reached $4.4 billion, and the deal priced at a spread 18 basis points tighter than the company's most recent domestic issue of similar maturity.
The extra costs were real: additional legal counsel in two jurisdictions, listing fees and roughly six weeks more preparation. On a $1.2 billion ten-year issue, though, 18 basis points is about $2.16 million of interest saved every year, so the fictional finance director judged the trade comfortably worthwhile and made the structure the default for future issues above $750 million.
Watch out
Common mistakes.
- Believing a global bond is denominated in several currencies. It has one currency of denomination and is simply sold and settled in several markets at once.
- Confusing a global bond with a eurobond. A eurobond is issued outside the jurisdiction of the currency it is denominated in, while a global bond is deliberately offered across several markets including the domestic one.
- Judging the cost of the issue by the coupon alone. Pricing below par, underwriting fees and legal costs all raise the effective borrowing rate, which is why the yield to maturity is the number that matters.
Questions
People also ask.
Who typically issues global bonds?
Sovereigns, supranational institutions such as development banks, and large investment-grade corporates, because the fixed costs of a multi-market issue need a large deal to justify them.
Does buying one give me currency diversification?
Not by itself, since your exposure is to the currency the bond is denominated in regardless of where you bought it.
Why would an issuer accept the extra complexity?
Because a wider investor base normally produces a larger book and a tighter spread, and on a deal of a billion dollars or more even a few basis points is a meaningful annual saving.
