When a bank's derivatives salesperson talks about "corporates," they mean the treasury functions of non-financial companies — from multinational manufacturers hedging currency exposure on overseas revenues, to utility companies locking in energy input costs, to investment-grade issuers converting a fixed-rate bond into floating-rate funding. Understanding what corporates need, and why, is fundamental to working in any product area where they are clients.
Why Corporates Use Derivatives
The driving motivation is risk management, not speculation. A well-run corporate treasury identifies the financial risks that arise naturally from the company's operations and uses derivatives to reduce volatility in cash flows, earnings, or balance sheet values. Three categories of risk dominate:
Foreign Exchange Risk
A UK company that manufactures goods in the UK and sells them in USD faces FX risk: its revenues are denominated in a foreign currency, while its costs are in sterling. If the pound strengthens against the dollar, those dollar revenues convert to fewer pounds, squeezing margins without any change in the underlying business. The treasury team will typically hedge a proportion of the forecast foreign currency revenues using FX forwards — agreeing today to sell USD and buy GBP at a fixed rate for settlement in three, six, or twelve months. Options (vanilla puts on USD) may be used where there is uncertainty about the volume of foreign currency receipts, allowing the company to participate in favourable moves while capping the downside.
Interest Rate Risk on Debt
Corporates borrow at both fixed and floating rates. A company that has issued a floating-rate bond or drawn on a revolving credit facility linked to SONIA (or SOFR in the US) faces interest cost uncertainty if rates rise. It may enter a pay-fixed, receive-floating interest rate swap — locking in a fixed interest cost while leaving the underlying loan in place. Conversely, a company that has issued a fixed-rate bond but wants to benefit from falling rates may use a receive-fixed swap to create a synthetic floating-rate exposure.
Commodity Input Costs
Airlines hedge jet fuel costs using crude oil or jet fuel derivatives. Food manufacturers hedge wheat or cocoa. Energy-intensive industrials hedge electricity and gas prices. The instruments used range from vanilla commodity swaps (paying a fixed price, receiving the floating market price) to options and structured collars. Commodity hedging is often the most complex area for corporate treasury teams, as the basis risk between the traded instrument and the actual commodity purchased can be significant.
The ISDA Master Agreement and CSA Negotiation
Before a corporate can trade any OTC derivative with a bank, the two parties must have an ISDA Master Agreement in place. The ISDA Master Agreement is a standard bilateral contract that governs all OTC derivative transactions between the parties. The Schedule to the Master Agreement sets out the elections and amendments the parties have agreed, and the Credit Support Annex (CSA) governs the collateral arrangements.
For corporate clients, CSA negotiation is often contentious. Banks prefer two-way collateral posting — where both parties post variation margin daily — because this reduces their counterparty credit risk and, since EMIR margining requirements, is increasingly the regulatory default. Many corporates resist two-way posting because it introduces cash flow uncertainty: a company that has entered a swap to hedge a future bond coupon does not want to face margin calls that require it to post cash today if the swap moves against it. Threshold-based CSAs (where collateral is only posted above a specified exposure level) and one-way CSAs (where only the bank posts collateral) have historically been common with investment-grade corporates, though regulatory pressure has shifted this landscape considerably.
Hedge Accounting Under IFRS 9
For listed companies reporting under IFRS, derivatives used for risk management purposes must be accounted for carefully to avoid artificial volatility in reported earnings. Under IFRS 9, a derivative that is designated as a hedging instrument in a qualifying hedge relationship benefits from hedge accounting treatment, which broadly aligns the recognition of gains and losses on the derivative with the recognition of gains and losses on the hedged item.
Three types of hedge relationships are recognised under IFRS 9:
- Fair value hedge: Hedges the exposure of a recognised asset or liability to changes in fair value. Example: hedging the fair value of a fixed-rate bond using a receive-fixed swap.
- Cash flow hedge: Hedges the variability in future cash flows attributable to a particular risk. Example: hedging forecast USD revenues using FX forwards. Gains and losses on the hedging instrument are recognised in Other Comprehensive Income (OCI) and recycled to profit or loss when the hedged cash flow affects profit.
- Net investment hedge: Hedges the foreign currency risk on a net investment in a foreign operation.
The treasury team must document the hedge relationship at inception and demonstrate ongoing effectiveness — the degree to which the hedge offsets changes in the value or cash flows of the hedged item. Ineffectiveness (the portion of the hedge gain or loss that does not offset the hedged item) flows directly through the income statement. Banks advising corporate clients on hedging strategy need to understand these accounting implications, since a hedge that works economically but creates accounting volatility will not be acceptable to the corporate's CFO.
Hedging a Bond Issuance: A Worked Example
Consider a UK investment-grade corporate that issues a €500 million 7-year fixed-rate bond at a coupon of 3.5%. The company's functional currency is sterling, and it wants floating-rate sterling funding — not fixed-rate euro funding. It will use a cross-currency swap to achieve this.
At inception of the swap: the company receives €500 million from the bond investors, pays those euros to the swap counterparty (the bank), and receives £435 million (at the prevailing EUR/GBP rate). Over the life of the bond, the company pays GBP SONIA plus a spread to the bank and receives 3.5% EUR fixed from the bank — which it passes through to the bondholders as the coupon. At maturity, the company repays €500 million to the bond investors (having received it from the bank in the final exchange) and repays £435 million to the bank (from its own sterling funding). The net effect is that the company has raised floating-rate sterling funding, and the currency and fixed/floating basis risk has been transferred to the bank.
The all-in cost to the company is the GBP SONIA spread on the swap plus the fees paid to the bookrunners for the bond issuance. The bank prices the cross-currency swap taking into account XVA charges (CVA, FVA) and the basis swap spread reflecting the relative demand for EUR versus GBP funding in the cross-currency market.
