Bonds vs stocks

A bond is a loan you make to an issuer in exchange for a stated yield and a promise to return the principal at a stated date. The issuer can be a government, a state-owned enterprise, or a corporation. Whoever it is, the structure is the same: you hand over money today, the issuer pays interest over the life of the bond, and the principal comes back at maturity. The cash flows are contractual. Missing a payment is a default. The bond does not give you a vote in the issuer's affairs and does not benefit if the issuer's business turns out to be unusually profitable; it simply pays what was agreed.

A stock is a fractional ownership claim on a company. When you buy a share, you own a slice of whatever profit and asset value remains after every creditor has been paid. There is no contractual amount the company owes you back; the share simply represents your slice of the residual. If the business does well over decades, the share becomes more valuable and may pay out part of its profits as dividends. If it does poorly, the share loses value and may never recover. Stocks carry voting rights at shareholder meetings, but for retail-sized positions the practical effect of voting is limited.

The two instruments answer the same question (where do I put my money) with structurally opposite mechanics. A bond is a credit relationship: predictable cash flow, fixed end date, modest variation around the agreed yield. A stock is an ownership relationship: optional cash flow, no end date, wide variation tied to business performance. Lending is safer in the year-to-year sense; owning is safer in the keeping-up-with-inflation-over-decades sense. Most household portfolios end up holding both, in some mix that reflects what the household is actually saving for. The page that follows this one (Asset Allocation) covers how that mix is decided.

LATAM retail historically holds significantly more bonds than US retail, and not by accident. Local nominal yields are unusually high by US standards: CETES around 9 to 10%, Tesouro Selic around 10 to 12%, Chilean instruments around 5 to 7%. Those numbers make local-currency bonds look attractive on a headline basis, and for a household that earns and spends in the same local currency they often genuinely are. The catch is that local nominal yields are eaten by local inflation in a way US yields are not, and the same household saving for goals more than a decade out usually needs USD-equity exposure as a hedge. The bond-vs-stock distinction is therefore the first decision in the chain, before any allocation math gets started.

Four threads pull this together for the LATAM investor. First, a stock represents ownership of a real business with claims on actual profits, while a bond represents a contractual loan; the two carry fundamentally different risks and returns. Second, the right blend of the two is an asset-allocation question: a single weight vector that depends on time horizon, income need, and risk tolerance, and that drifts with goals. Third, the LATAM bond layer most retail accounts can actually touch is local-currency government bonds like CETES or Tesouro Selic, which behave differently from US treasuries even at the same nominal yield. Fourth, inflation eats nominal yields; a 10% bond yield in a country with 6% inflation is closer to a 4% real yield, which is what changes the bond-vs-stock comparison once you do the arithmetic honestly.
