Investment bonds are debt securities where the interest rate is not fixed but depends on the performance of underlying assets like stocks, commodities, or indices. Unlike standard bonds with predictable fixed coupons, they offer potentially higher returns tied to market conditions while protecting the principal at maturity.
Like regular bonds, investment bonds have a set maturity date when the issuer repays the face value. However, coupon payments vary based on the dynamics of reference assets such as equities, commodities, or raw materials.

What Are Investment Bonds
Investment bonds are debt securities where the interest rate is not fixed but depends on specific conditions. This structure allows potential returns far exceeding those of fixed-rate bonds.
How Their Returns Are Determined
Returns on investment bonds consist of two parts:
- a fixed income component, typically set at a minimum level;
- a variable income tied to changes in the value of underlying assets.

Types of Investment Bonds
Investment bonds fall into three main types, differing by how underlying assets affect returns.
Participation Bonds
In these bonds, investor returns directly track participation in the underlying asset’s price change via a participation coefficient, which can be above or below 1. Payouts typically occur at maturity.
For example, a participation bond linked to MOEX Index growth with a 1.2 coefficient. If the index rises 10% by maturity, the return is:
return = MOEX Index gain × participation coefficient
That is, 10% × 1.2 = 12%.
Participation bonds suit investors betting on asset growth without risking principal.
Investment Bonds with Accumulation Corridor
These set a price range for the underlying asset. Investors earn returns for each day the price stays within the corridor.
For example, an investment bond tied to gold with 9% annual yield and a ±$150 corridor from the issue price. If gold is $2000 per ounce at issuance, returns accrue daily while prices stay between $1850-$2150 at the 9% rate.
These bonds fit investors uncertain about directional price moves.
Bonds with Memory Effect
Investors earn if the underlying asset exceeds a barrier. Often based on a basket of assets, with barriers set by the worst performer.
The memory effect means missed payouts due to unmet conditions carry over to future dates if conditions are then met.
For example, a bond on a basket of four stocks pays 4.5% every six months if no stock drops over 8%. If breached, the coupon is “remembered” and paid later upon compliance, including prior misses.
These suit investors seeking steady income.
Advantages of Investment Bonds
- no principal risk – the issuer must repay face value at maturity;
- high potential returns – often beating deposits, inflation, and fixed bonds;
- strong liquidity – sell anytime on the secondary market;
- available via individual investment accounts (IIS).
Investment bonds provide high returns without capital risk, ideal for yield-focused investors.
