A high-risk deadbeat bond

850_Macri-634 — Mauricio Macri: a big improvement over the populists

"Argentina's can't-miss offer to participate in its first non-deadbeat century." This headline on the Dealbreaker website greeted the news that South America's second-largest economy had issued a 100-year bond. Cynical maybe, but basically true. Argentina has defaulted on its sovereign debt eight times since independence in 1816, notes FT Alphaville. Three of those defaults were in the last 23 years alone. Yet investors piled in Argentina sold $2.75bn in debt and attracted $9.75bn in orders. Who would buy this stuff?

First, a quick refresher course. Bonds are IOUs issued by firms or governments. The issuer promises to pay the lender a fixed amount of interest (the "coupon" in this case, 7.125%) each year, and their money back when the bond matures. The bond yield (the coupon divided by the bond price) varies depending on how likely the issuer is to repay the debt, and on interest rates and inflation in the wider economy (a fixed income loses its appeal as inflation rises, for example). These particular bonds sold for 90 cents in the dollar, giving a yield of just under 8% (7.125/90). The bonds are denominated in US dollars, which means investors don't take any currency risk, although the issuer itself does.

So why would investors buy them? The key is a thing called "duration". There's a more technical explanation here, but in practical terms, duration measures how sensitive a bond is to changes in economic conditions. If things get better (inflation falls, growth picks up, interest rates remain stable), the bond price will go up and the yield will go down. If things get worse, the opposite happens. The size of the move is driven by the duration of the bond.

The further into the future a bond's maturity date, the longer its duration. So if it turns out that Argentina has turned over a new leaf (and the new government of Mauricio Macri is a big improvement), then there's a good chance the bond price will rise. Current holders could then sell they don't have to hold until maturity. If yields fall in line with those on other big South American economies, it would imply double-digit capital gains, says the Financial Times.

Secondly, as long as Argentina continues to service its debt, a near-8% yield is attractive in these yield-starved days. Of course, just because Macri is doing a good job now doesn't mean he'll keep doing so. And 100 years from now, who knows? As FT Alphaville notes, most investors "look little further than the next couple of years", but instead assume that if things go wrong, they'll spot trouble early enough to get out. Still, 8% doesn't seem enough to compensate for the risk of a populist resurgence.
