Choosing and Comparing Interest Rate Hedging Methods in AFM

Updated 11 October 2026 · Fact-checked

Choosing an interest rate hedge means matching a tool to the exposure and the company's view. FRAs and futures fix a rate, options give a cap and keep upside, and swaps change fixed to floating over longer periods. You compare cost, certainty, flexibility, size, term and risk, then recommend one.

Understand Choosing and Comparing Hedging Methods

Interest rate risk is the chance that rates move against you. A borrower with floating debt loses if rates rise. A depositor or a fixed-rate borrower loses if rates fall, through lost income or a missed chance to borrow cheaply. Hedging is about choosing how much of that risk to remove and at what cost.

The tools fall into two groups. Fixing tools lock in a rate and remove both the bad and the good outcome. These are forward rate agreements (FRAs), interest rate futures and swaps. Option tools (interest rate options, caps, floors and collars) protect against the bad move but let you keep the good one. You pay a premium for that right.

The tools also differ in practical ways. FRAs are over the counter and tailored in amount and dates, but they cover short periods, usually up to about a year or two. Futures are exchange traded with standard sizes and dates, so there is basis risk and margin cash flow, but they are liquid and easy to close out. Options can be exchange traded or OTC. Swaps suit longer-term debt, can be arranged for many years and need no premium, but they carry counterparty risk and are hard to exit.

The recommendation depends on the company's risk view. If management is sure rates will rise, a fixing tool works. If it is unsure and wants to keep the benefit of a fall, an option is better, though the premium is a sure cost. If the debt is long term and the aim is to change its nature, a swap is the natural choice. A treasury policy should also say how much exposure to hedge, who can approve deals and which instruments are allowed, with speculation forbidden.

In AFM you are rarely asked only to calculate. You are asked to advise. So your answer must tie the instrument to the facts: the amount, the period, the direction of exposure, the company's attitude to risk and its ability to manage margins and premiums.

Key rules to remember

FRA settlement idea: Borrower pays fixed FRA rate effectively; bank pays (market rate − FRA rate) × amount × period if market rate is higher; For a borrower, FRA gives an effective rate equal to the FRA rate, whichever way rates move. The settlement is normally discounted at the market rate.
Interest rate future price: Futures price = 100 − expected interest rate (%); A borrower sells futures to hedge; a depositor buys. A rate rise lowers the price, so the seller gains.
Futures hedge number of contracts: Contracts = (Exposure ÷ Contract size) × (Loan period ÷ Contract period); Round to a whole number of contracts. Hedge outcome includes basis difference at closing.
Futures gain or loss: Gain/loss = Ticks moved × tick value × number of contracts; For a 3-month contract, a tick of 0.01% on a standard contract is worth the contract size × 0.01% × 3/12.
Option outcome for a borrower: Effective rate = lower of (market rate, option strike rate) + premium cost; The option is exercised only if the market rate is above the strike. Include premium, ideally with its financing cost.
Swap net rate for a borrower: Net cost = rate paid on loan + swap rate paid − swap receipt; Check what is received and what is paid. Add any bank fee. The swap changes the rate basis, not the loan itself.
Collar: Borrower buys cap at higher strike and sells floor at lower strike; The floor premium reduces the cap cost. The effective rate lies between the floor and cap strikes, plus any net premium.

How to solve Choosing and Comparing Hedging Methods questions

Use this order for any 'which hedge should we recommend' requirement. It keeps your answer applied rather than generic.

1Identify the exposure: borrower or lender, floating or fixed, amount, start date and length.
2Note the company's risk view and constraints: sure of the rate direction or not, wish to keep upside, cash available for premium or margin, size, and treasury expertise.
3Pick the candidate tools that fit the period: FRA or futures for short periods, options for flexibility, swaps for long debt.
4Calculate the outcome for each tool if the question gives data, under at least a rate rise and a rate fall. Include premium, margin or fees.
5Compare on cost, certainty, flexibility, basis risk, counterparty risk, liquidity and ease of exit.
6Recommend one tool and say why it fits this company and view. Say why you reject the others.
7Add the points on policy: how much to hedge, no speculation, authority limits, review and monitoring.
8Finish with a short caveat, such as the risk that rates move the other way or that the view is wrong.

Quickest way: Four-question shortcut for recommendations

When to use it: Use it when time is short and the question gives few numbers, or when you must plan your written answer before calculating.

Term: under about a year means FRA, futures or options; multi-year means a swap or longer-dated option.
View: confident means fix with FRA, futures or swap; unsure or wants upside means option.
Cash: cannot afford premium or margin? FRA or swap. Can afford premium? Option.
Size and fit: odd amounts or dates favour OTC tools; small standard amounts suit futures.
Write the recommendation in one sentence, then give two advantages and two drawbacks of it.

Common mistakes in Choosing and Comparing Hedging Methods

Recommending an instrument without linking it to the company's facts.
Students memorise lists of advantages and drawbacks and paste them in.
Fix: Open each point with the scenario: the amount, period or risk view. Then say why the tool fits or does not.
Using the wrong side of the market: buying futures to hedge a borrowing.
Confusing the price movement with the rate movement.
Fix: Price = 100 − rate. A borrower fears a rate rise, which is a price fall, so sells futures.
Ignoring the option premium when comparing with an FRA or swap.
The premium is paid upfront and looks separate from interest.
Fix: Add the premium to the effective rate, and if asked, carry it forward at the borrowing rate.
Saying options remove all risk and cost nothing in a favourable move.
Focus on keeping the upside.
Fix: State that the premium is a certain cost and is lost if the option is not exercised.
Forgetting swap counterparty risk and the difficulty of exit.
Swaps are seen as cheap because there is no premium.
Fix: Mention default risk, the cost of reversing the swap and that you lose the benefit of a fall in rates.
Ignoring basis risk and margin on futures.
Calculation focus hides the practical drawbacks.
Fix: Say that standard contracts may not match the exposure and that daily margin needs cash and may cause cash flow strain.

Worked examples

Example 1

Kavya Ltd expects to borrow ₹50 crore at floating rates in 3 months for 6 months. The directors think rates will rise but want to keep the benefit if they fall. The treasurer is worried about cash tied up in margin. Recommend a hedge from an FRA, interest rate futures or an interest rate option.

Show the solution

Exposure: a borrower, with a future floating-rate loan, so the risk is a rate rise. The period is 6 months, starting in 3 months.
View and constraint: the directors expect a rise but want to keep upside, and there is concern over margin cash.
FRA: fixes the rate for the 3 by 9 period with no premium and no margin, but removes the benefit if rates fall.
Futures: standard sizes and dates cause basis risk, and daily margin conflicts with the cash concern. Gains and losses offset the loan, so upside is also lost.
Option: sets a maximum rate and keeps the benefit if rates fall. The cost is the premium, paid upfront. There is no margin on a bought option.
Fit: the option is the only tool that meets both the wish to keep upside and the cash concern over margin, although the premium must be afforded. If the board values cost certainty more than the upside, an FRA is the alternative.

Answer: Recommend an interest rate option (a cap on the borrowing rate). It limits the rate if rates rise, keeps the benefit of a fall, and has no margin calls. The premium is a sure cost. An FRA would be the fallback if the premium is too high and the board accepts losing the upside.

Example 2

Meera plc has ₹80 crore of floating-rate debt with 5 years left, at a floating rate plus 1%. It wants certainty over interest cost for the full period. A bank offers a 5-year swap where Meera pays 6% fixed and receives the floating reference rate. Calculate Meera's net interest cost if the floating reference rate is 5% and then 7%, and explain why a swap is preferred to futures.

Show the solution

Loan cost = floating rate + 1%.
Swap: pay 6% fixed, receive floating rate.
If the floating rate is 5%: loan 5% + 1% = 6%. Pay swap 6%. Receive 5%. Net = 6% + 6% − 5% = 7%.
If the floating rate is 7%: loan 7% + 1% = 8%. Pay swap 6%. Receive 7%. Net = 8% + 6% − 7% = 7%.
The net cost is 7% in both cases: the floating reference rate cancels, leaving fixed 6% plus the 1% margin.
Futures are short dated, so a 5-year hedge needs repeated rollovers, with basis risk and margin. An FRA does not cover this term. The swap fits the term.

Answer: Net cost is 7% a year in both cases (6% fixed plus the 1% margin). A swap is preferred because it covers 5 years in one deal. The drawbacks are counterparty risk, difficulty in exiting and no benefit if rates fall.

Exam tips

Always state the exposure direction first. Marks are lost when the hedge is on the wrong side.
Give a clear recommendation, not a list. Examiners reward a decision justified by the scenario.
When numbers are given, test both a rate rise and a rate fall. It shows the option's asymmetry and the fixed tools' certainty.
Show professional skills: weigh the risk view, challenge the directors' forecast and note that hedging policy should avoid speculation.
Use the term of the debt as a filter. Short exposure points to FRAs, futures or options; long exposure points to swaps.

Practice questions from The use of financial derivatives to hedge against interest rate risk

Choosing and Comparing Hedging Methods: frequently asked questions

Which interest rate hedge should I recommend in the AFM exam?

Match the tool to the term, the risk view and the cash position. Use an FRA or futures to fix a short-term rate, an option to keep upside for a premium, and a swap for longer debt. Always justify with the scenario facts.

What is the difference between an interest rate swap and an option?

A swap fixes or changes the rate basis over a long period with no premium, but it removes the benefit of favourable moves and carries counterparty risk. An option sets a limit and keeps the upside, but you pay a premium upfront.

Why are FRAs and futures both used?

FRAs are over the counter and can be tailored to the exact amount and dates. Futures are exchange traded and liquid but come in standard sizes, so there is basis risk and margin is needed.

What should a treasury hedging policy include?

It should set the targets for exposure to hedge, the approved instruments, authority limits and reporting. It should also forbid speculation and require regular review of positions and counterparties.
