The Formal Theorem

Let τ \tau be the random default time of a firm, and let R R denote the recovery rate, defined as the fraction of the face value F F recovered at τ \tau . Under a risk-neutral measure Q \mathbb{Q} , the price B(t,T) B(t, T) of a risky zero-coupon bond paying F F at maturity T T is given by:
B(t,T)=EQ[e−∫tTrsds(FI{τ>T}+RFI{τ≤T})∣Ft] B(t, T) = \mathbb{E}^{\mathbb{Q}} \left[ e^{-\int_t^T r_s ds} (F \mathbb{I}_{\{\tau > T\}} + R F \mathbb{I}_{\{\tau \le T\}}) \mid \mathcal{F}_t \right]
where rs r_s is the stochastic short rate and I \mathbb{I} is the indicator function.

Analytical Intuition.

Imagine the bond as a fragile vessel sailing toward maturity T T . At any point, a sudden storm—the default time τ \tau —might sink the vessel. The recovery rate R R represents the salvage value recovered from the wreckage should the storm hit before the destination. In advanced finance, we treat this recovery not as a static salvage, but as a dynamic component of the total expected return. If the vessel reaches T T safely, we receive the full face value F F . If the vessel sinks at τ≤T \tau \le T , we are entitled only to the fraction R R of F F . Pricing this requires us to integrate across all possible 'sinking' scenarios, weighted by the risk-neutral probability of the firm's health. We are essentially blending the 'risk-free' path with the 'salvage' path, using the stochastic short rate rs r_s to discount these future cash flows back to the present. The complexity lies in the correlation between the default intensity and the recovery amount, as market stress often causes R R to plummet exactly when default risk spikes.
CAUTION

Institutional Warning.

Students frequently conflate the recovery rate R R with the recovery *value*. Furthermore, they often assume R R is deterministic, ignoring 'wrong-way risk' where the recovery value drops precisely when default probability increases, failing to account for the stochastic dependency between τ \tau and R R .

Academic Inquiries.

01

Is the recovery rate always constant?

In basic models, yes. In advanced stochastic models, the recovery rate is often modeled as a stochastic process Rt R_t , which may be correlated with the default intensity λt \lambda_t and the interest rate rt r_t .

02

What is the difference between Recovery of Face Value (RFV) and Recovery of Treasury (RT)?

RFV assumes a fixed percentage of the principal is paid at default, whereas RT assumes the recovery equals a fraction of the market value of an equivalent default-free bond just before default.
