Repurchase Agreement / Buyback | Other Compliant Contracts

Definition and Scope

The standard covers the Shari'ah rules for repurchase agreements where:

A seller sells goods to a buyer.
The seller, or sometimes the buyer, has the option or obligation to repurchase the goods.
The repurchase price and timing are stipulated in the contract.
The repurchase is used for liquidity, financing, or securitization purposes.

Three Types of Repurchase Agreements

Type 1: Seller's Promise or Option to Repurchase (Wa'd)

The seller unilaterally promises to buy the goods back at a future date or upon demand. Example: A bank sells goods to a customer but promises the customer that the bank will buy them back after 6 months at cost + fair return. This gives the bank flexibility to unwind the transaction.

Type 2: Buyer's Option to Require Repurchase

The buyer holds the option to force the seller to repurchase. Example: A financing customer sells goods to the bank but has the right to require the bank to buy them back at a fixed price. This protects the customer's liquidity.

Type 3: Mutual Agreement (Khiyar al-Ijabah)

Both parties have agreed that if either wants to, they may reverse the transaction within a specified period. This is rare but provides maximum flexibility.

Permissibility Conditions

For a repurchase agreement to be Shari'ah-compliant:

The initial sale must be genuine: goods must exist and actually transfer ownership.
The repurchase price must be pre-agreed or determined by an objective method.
The repurchase must not disguise an interest-bearing loan.
Time delays must be reasonable; an instantaneous reversal suggests a sham.
The goods must have real economic substance, not mere financial paper.

Key prohibition: The structure is impermissible if:

The seller sells and immediately repurchases at a higher price, creating interest (riba).
The buyer effectively lends money to the seller against collateral.
The price difference is not justified by a genuine change in the goods' condition or market value.

Application in Islamic Finance

Liquidity management: Banks often use repurchase agreements to manage short-term liquidity. A bank buys goods from a supplier with the understanding it will sell them back after a short period if liquidity improves. This is permissible if the sale is genuine.

Securitization backing: Islamic securities (Sukuk) often use repurchase agreements to ensure bondholders get principal back at maturity. The originator promises to repurchase the underlying assets at the bond maturity date.

Commodity financing: A business may sell inventory to a finance partner with a promise or option to buy it back as sales improve. This is a repurchase or buyback liquidity structure, not classical tawarruq. Tawarruq has its own sale sequence and is covered separately, though both structures can appear in liquidity management.

Prohibited Structures

Repo as disguised loan: Bank lends $1M to a customer against gold collateral. The structure is:

Customer sells gold to the bank for $1M.
Bank immediately buys it back for $1.05M payable in 30 days.
Effect: customer borrowed $1M for 30 days at a 5% annual interest equivalent.

This violates the Repurchase Agreement standard because the "sale" is not genuine. It is a funding mechanism.

Price manipulation in repurchase: Seller and buyer agree that repurchase price will be $100 (cost $50), but only if certain conditions occur (e.g., buyer defaults). If the price difference is not justified by genuine risk or market movement, this may be disguised interest.

Three Diagnostic Questions

When examining whether a particular repurchase structure is genuine or disguised, the practitioner can apply three diagnostic questions; the answers usually reveal whether the structure functions as a sale or as a hidden loan.

Did the asset substantively pass into the buyer's control?

A genuine sale gives the buyer real disposition rights — to use, lease, on-sell, or hold. If the asset never leaves the seller's warehouse, the seller continues to insure and account for it as inventory, and the buyer has no realistic way to deal with it independently, the answer is no — and the "sale" is in form only. Documentation that recites a delivery without operational reality is a marker.

Is the repurchase price independent of the time value of money?

A genuine repurchase price reflects the asset's expected condition or market at the repurchase date — not a number arrived at by adding "interest" to the original sale price. If the differential between sale price and repurchase price is mathematically equal to a market interest rate over the holding period, that is the structural fingerprint of riba. The cure is to set the repurchase price by reference to fair value at the time of repurchase or to a separately negotiated number, not a time-multiplied original price.

Could the parties have walked away mid-stream?

In a genuine sale-and-future-repurchase, the buyer is not contractually bound to sell back; the buyer might decide to keep the asset, on-sell it, or repurchase only partially. If the parties have, in substance, locked in a complete reversal at inception — through synchronised bilateral undertakings — the structure is not a sale but a financing dressed as one. The cure is to leave one side's commitment as a unilateral promise and the other side's acceptance as a future, contingent decision.

Liquidity Use Cases — Permissible vs Doubtful

Inventory financing with a genuine call option — a manufacturer sells inventory to a finance partner outright; the finance partner holds, insures, and accounts for the inventory; the manufacturer holds a unilateral promise to repurchase if and when sales conditions improve. Permissible.
Sale-and-leaseback for capital release — the customer sells equipment to the institution and immediately leases it back at a market rental, with no pre-priced repurchase. Permissible, because the leaseback is a separate contract on its own economic terms.
Same-day buy-and-sell on the same commodity at synchronised prices — a bank buys metal from a customer in the morning and sells it back to the customer in the afternoon at a higher price. Doubtful at best, because there is no genuine economic interval and the price differential maps directly onto a financing return.
Tripartite organised tawarruq purely for cash — the customer buys a commodity from one institution on deferred terms and immediately sells it through a second institution for cash, with both transactions pre-arranged. Contested in mainstream circles; permitted under some institutional frameworks subject to strict conditions, rejected by others as a circumvention.
