Bonds and fixed income: the mechanics of lending

For the members of the Financial Market Club, FSJES

While equities represent ownership, bonds represent debt. A bond is a formal, legally enforceable contract between a borrower and an investor: the investor lends principal today, the borrower pays periodic interest (coupons), and the borrower returns the full face value at maturity.

In Morocco, the fixed income market dwarfs the equity market in daily transaction volume. The sovereign debt market, managed by the Direction du Tresor et des Finances Exterieures (DTFE) under the Ministry of Economy and Finance, forms the bedrock of the entire Moroccan financial architecture.

The structure of a bond#

Every bond contract is defined by four core parameters:

  1. Face value (valeur nominale): The principal amount borrowed per unit (typically 100,000 MAD for Moroccan Treasury bonds, or 10,000 MAD for corporate debentures).
  2. Coupon rate (taux facial): The fixed annual percentage paid to the bondholder. A 3% coupon on a 100,000 MAD nominal pays 3,000 MAD each year.
  3. Maturity (maturite): The date on which the issuer repays the face value and terminates the debt. Moroccan Treasury lines range from 13-week short-term bills (Bons du Tresor a court terme) to 30-year long-term bonds.
  4. Market price (prix d'adjudication / cours): What buyers pay in the market today, expressed either in dirhams or as a percentage of face value (e.g., 98.5% of nominal).

The inverse law: prices and yields move in opposite directions#

The central law of fixed income is that bond prices and market yields are inversely related. When market interest rates rise, existing bonds with lower coupons become less attractive, and their prices fall until their yield to maturity matches the new prevailing market rate.

Suppose you purchase a 5-year Moroccan Treasury bond with a face value of 100,000 MAD paying a 3% annual coupon (3,000 MAD). If Bank Al-Maghrib raises the policy rate, pushing newly issued 5-year Treasury yields up to 4%, no rational investor will pay 100,000 MAD for your 3% bond. To sell your bond on the secondary market, you must discount its price to roughly 95,500 MAD, so that the new buyer receives the 3,000 MAD coupon plus the capital gain at maturity, yielding exactly 4%.

The Moroccan Treasury auction system#

In Morocco, sovereign debt is not sold over a counter; it is issued through bi-monthly Treasury auctions (adjudications des Bons du Tresor) coordinated by Bank Al-Maghrib.

Authorized primary dealers, known as Spécialistes en Valeurs du Trésor (SVT) comprising major Moroccan banks and brokerage houses (Attijariwafa Bank, BCP, CDG Capital, BMCE Capital, Societe Generale Maroc), submit blind yield bids. The Treasury ranks bids from lowest yield to highest, accepting bids until its financing quota is filled. This Dutch auction mechanism establishes the official Moroccan sovereign yield curve (courbe des taux souverains), which serves as the risk-free reference benchmark for pricing mortgages, corporate loans, and mutual funds across the kingdom.

Corporate debt and Sukuk in Morocco#

Beyond the Treasury, Moroccan corporations issue corporate bonds (emprunts obligataires) approved by the AMMC. Issuers like OCP Group (Office Cherifien des Phosphates), autoroutes du Maroc (ADM), and telecom operators use fixed income to fund multi-billion dirham infrastructure projects.

Furthermore, following the enactment of Law 33-06, Morocco established a legal framework for participatory finance and sovereign Sukuk. In October 2018, the Moroccan Treasury issued its inaugural sovereign Sukuk Ijara, raising 1 billion MAD backed by usufruct rights on state real estate assets. Sukuk provide an asset-backed alternative to conventional debt, paying rental yields rather than interest, broadening capital market access to participatory banks (banques participatives) and takaful insurance companies.

What the simulator cannot model#

While fixed income forms the backbone of the Moroccan financial architecture, our simulated trading platform focuses exclusively on equities: it does not model sovereign bond auctions, secondary fixed income dealing, or yield curve duration shifts. In addition, real-world bond yields are not guaranteed against unexpected inflation shocks or credit restructuring. Learning the arithmetic here provides the foundation before you encounter debt instruments in banking and asset management.

For discussion#

  1. If the DTFE issues 10-year Treasury bonds at 3.5% and inflation accelerates to 4.5% over the holding period, what is the investor's realized real rate of return?
  2. Why does a 20-year Moroccan Treasury bond experience a much larger percentage price decline than a 2-year Treasury bill when market yields increase by 50 basis points?
  3. How do the Spécialistes en Valeurs du Trésor (SVT) ensure liquidity in the secondary market for Moroccan government securities under Law 45-12?
