Hedging the Strait: How State Oil Buyers Can Manage the Next Oil Shock

The US–Israeli strikes on Iran and Tehran’s swift retaliation across the region have once again placed the Strait of Hormuz at the centre of global economic risk. This 21-mile-wide chokepoint carries roughly one-fifth of the world’s oil and up to 30% of global LNG trade. Even the threat of disruption can send crude markets sharply higher.
For small, import-dependent economies like Mauritius, thisis a balance-of-payments risk, a fiscal risk, and ultimately an inflation risk. Analysts warn that sustained oil at $100 per barrel could add 0.6–0.7 percentage points to global inflation. For emerging and small island states, the pass-through is often faster and more painful. Fuel prices affect transport, electricity, food production, and logistics simultaneously. Monetary policy alone cannot absorb that shock.
State oil purchasing agencies — such as the State Trading Corporation (STC) in Mauritius — therefore face a critical question: how to stabilise national fuel costs without exposing public finances to uncontrolled volatility?
The answer lies in structured risk management. Oil price volatility creates three layers of exposure:
- Price risk – Brent spikes due to supply disruptions.
- Currency risk – Oil is priced in USD, compounding exposure if the local currency weakens.
- Cash-flow risk – Sudden procurement cost increases strain budgets and subsidies.
While financial tools cannot solve physical supply disruptions, they can significantly reduce price and currency risk.
Futures Contracts allow an agency to lock in a fixed purchase price for future deliveries. This provides budget certainty but requires margin management and liquidity buffers.
Call Options function like insurance. By purchasing a call option, the agency sets a maximum effective price. If oil surges to $120, the option offsets the spike. If prices fall, the agency buys at lower market levels and only loses the premium paid. This preserves downside benefit while protecting against extreme upside risk.
Zero-Cost Collars combine buying a call (price ceiling) and selling a put (price floor). The premium received from selling the put offsets the cost of the call, eliminating upfront expense. The trade-off is that the agency sacrifices some benefit if oil prices collapse below the floor. Collars create a defined price band — protecting against spikes while giving up part of the downside.
Swaps allow the agency to exchange floating market prices for a fixed price through a bank counterparty. This is flexible but requires strong governance and counterparty risk management.
FX Forwards and Swaps are essential companions. Hedging oil without hedging USD exposure leaves half the risk unaddressed.
A prudent approach might involve hedging 30–50% of forecast imports on a rolling basis, layering maturities across 6–12 months, and combining instruments depending on market conditions. Options may be preferable during geopolitical stress; swaps may be efficient during calmer periods.
Partial hedging stabilises budgets while retaining flexibility. Instead of hedging once a year, the agency hedges progressively. In March: hedge part of September imports; In April: hedge part of October imports; In May, hedge part of November imports. Every month, a new forward month is added. This avoids the risk of locking in prices at a single, potentially unfavourable moment.
