CAIIB BFM Exchange Rate Case Studies (2026): Cash, TOM, Spot, Forward Rates

The CAIIB BFM exchange rate case study is one of the most reliable scoring areas in the Bank Financial Management paper &mdash. If you know the value-date rules cold. Most candidates lose these marks not because the maths is hard.

But because they pick the wrong rate. Cash, TOM, spot or forward? Buy side or sell side?

This guide settles it for good.

Below you will learn exactly how a bank decides. Exchange rate applies to a foreign-currency transaction. How delivery dates and bank holidays change that choice.

And how a forward contract is booked using forward premium &mdash. With and without the bank’s margin. Then we walk through two fully solved CAIIB BFM case studies.

The same style the examiner uses.

Why the Exchange Rate Case Study Matters in CAIIB BFM

Banks deal in foreign currency every day — importers buy dollars. Exporters sell them, and treasuries hedge with forward contracts. Each deal must be priced with the correct rate on the correct value date. Get the date wrong and the bank’s book is mispriced.

That is why the CAIIB Bank Financial Management syllabus tests this through numerical case studies. The examiner gives you a rate sheet and a few transactions. Then asks which rate applies and what the rupee amount is. The logic never changes. So once you master it you can solve every variation.

This article is the third installment of our exchange-rate case study series. Building on the foundations laid in Parts 1 and 2.

The Four Value Dates: Cash, TOM, Spot and Forward

Every foreign-exchange transaction settles on a value date &mdash. The day the currencies actually change hands. There are four standard buckets, and knowing them is half the exam.

• Cash / Ready rate: Delivery happens on the same day as the deal (value today).
• TOM rate (Tomorrow): Delivery on the next working day (value tomorrow).
• Spot rate: Delivery on the second working day after the deal (T+2). This is the market benchmark.
• Forward rate: Delivery on any date beyond the spot date &mdash. A month later. A quarter later, and so on.

The Most Important Rule: Buy Low, Sell High

Foreign-exchange rates are always quoted two-way, like USD = Rs. 45.50 / 60. The left figure is the bid (the bank’s buying rate). The right figure is the ask/offer (the bank’s selling rate).

From the bank’s point of view the rule is simple: the bank buys foreign currency at the lower rate. Sells it at the higher rate. The customer always ends up on the worse side of the spread. Keep this single sentence in mind and most questions answer themselves.

Notice the pattern: the value date decides. Row of the rate sheet you read. And the buy/sell direction decides. Side of the spread you take.

CAIIB BFM Case Study 5: Choosing Cash, TOM, Spot and Forward Rates

On the 10th of January 2012. ‘Rich&rsquo. Bank’s Mumbai branch entered into the following foreign-currency sale. Purchase transactions:

• With Mr. Aman — sale of USD 2,000.00. To be delivered on the 10th of January (same day).
• With Mr. Bansal — purchase of USD 2,000.00. To be delivered on the 11th of January (next day).
• With Mr. Canada — purchase of USD 2,000.00. To be delivered on the 14th of January (12th &. 13th January are bank holidays).
• With Mr. Doctor — sale of USD 2,000.00. To be delivered on the 11th of February (forward).

The inter-bank USD/INR rates on 10th January 2012 are:

The Four Questions

Q1. Which rate applies to Mr. Aman, and what is the INR amount?(I) Rs.

45.50, Rs. 91,000   (II) Rs. 45.55, Rs.

91,100   (III) Rs. 45.60, Rs. 91,200   (IV) Rs.

45.85, Rs. 91,700

Q2. Which rate applies to Mr. Bansal, and what is the INR amount?(I) Rs.

45.85, Rs. 91,700

Q3. Which rate applies to Mr. Canada, and what is the INR amount?(I) Rs.

45.85, Rs. 91,700

Q4. Which rate applies to Mr. Doctor, and what is the INR amount?(I) Rs.

45.85, Rs. 91,700

Step-by-Step Solution

Mr. Aman (Q1) — same-day sale. Delivery is on the deal date itself, so the Cash rate applies.

Because the bank is selling dollars to the customer. It uses the higher side. Here the relevant cash figure works out to Rs.

45.60. Amount = Rs. 45.60 × 2,000 = Rs.

91,200. (Answer: III)

Mr. Bansal (Q2) — next-day purchase. Delivery is the very next day, so the TOM rate applies.

Because the bank is buying dollars from the customer. It uses the lower (bid) side = Rs. 45.55.

Amount = Rs. 45.55 × 2,000 = Rs. 91,100.

(Answer: II)

Mr. Canada (Q3) — purchase with holidays in between. Delivery is on 14th January.

But the 12th and 13th are bank holidays and must be excluded. Counting only working days from the 10th lands you on the spot value date (T+2). So the Spot rate applies.

And for a bank purchase the rate is Rs. 45.60. Amount = Rs.

45.60 × 2,000 = Rs. 91,200. (Answer: III)

Mr. Doctor (Q4) — forward sale. Delivery on 11th February is well beyond the spot date.

So this is a forward sale. Because the bank is selling dollars one month forward. It uses the higher (ask) side of the 1-month forward quote = Rs.

45.85. Amount = Rs. 45.85 × 2,000 = Rs.

91,700. (Answer: IV)

CAIIB BFM Case Study 6: Booking a Forward Contract with Forward Premium

On the 15th of April 2015, ZAIN Ltd. expects to receive USD 20,000.00 sometime within July 2015. ZAIN wants the bank to book a forward purchase contract for July 2015 (the bank is buying the dollars the exporter will deliver).

Given — the USD/INR inter-bank rates:

The Two Questions

Q1. At what rate is the forward contract booked if the margin is not considered?(I) Rs. 45.31   (II) Rs.

45.41   (III) Rs. 45.55   (IV) Rs. 45.57

Q2. At what rate is the forward contract booked if the margin is considered?(I) Rs. 45.31   (II) Rs.

Step-by-Step Solution

Why June’s premium, not July’s? The exporter can deliver on any day in July. Including the 1st of July.

To stay protected for the whole window. The bank prices the contract using the premium of the last completed month before delivery begins &mdash. That is June.

So the applicable premium is 31 paise.

Q1 — rate without margin. This is a bank purchase from an exporter. So we use the spot bid (Rs. 45.10) and add the June premium:

So the rate without margin is Rs. 45.41. (Answer: II)

Q2 — rate with margin. Because this is a purchase. The bank deducts its margin from the customer’s rate (the bank always keeps the spread in its favour):

So the quoted rate after margin is Rs. 45.31. (Answer: I)

How to Study Exchange-Rate Case Studies and Score Full Marks

Watching a lecture is not enough. Use this proven routine to make the rate choice automatic on exam day:

1. Read the value date first. Same day → Cash. Next day → TOM, T+2 → Spot, beyond → Forward.
2. Identify the direction. Is the bank buying or selling? Then apply “buy low, sell high.”
3. Strike out holidays before you count days to the spot date.
4. For windows. Use the last completed month’s premium so the bank is covered for the whole period.
5. Apply margin in the bank’s favour: deduct on a purchase. Add on a sale.
6. Solve by hand and time yourself with topic-wise mock tests until calculation becomes reflex.

Common Mistakes to Avoid

• Counting holidays toward the spot date. Bank holidays are always excluded.
• Taking the wrong side of the spread. The bank buys at the lower rate. Sells at the higher rate &mdash. Never the reverse.
• Using July’s premium for a July delivery window. Since delivery can fall on 1st July. The safe choice is June’s premium.
• Adding the margin on a purchase. On a bank purchase the margin is deducted. Lowering the customer’s rate.
• Confusing cash with spot. Cash is same-day; spot is T+2. They are different rows on the rate sheet.
• Forgetting the paise-to-rupee conversion. A premium of 31 paise is Rs. 0.31, not Rs. 31.

Frequently Asked Questions (FAQ)

What is the difference between cash, TOM and spot rates in CAIIB BFM?

The cash (or ready) rate is for same-day delivery. The TOM rate is for delivery on the next working day. And the spot rate is for delivery on the second working day (T+2). The forward rate covers any delivery beyond the spot date.

How does a bank decide which side of the quote to use?

The bank buys foreign currency at the lower (bid) rate. Sells it at the higher (ask) rate. So when the customer is buying dollars the bank uses the higher figure. And when the customer is selling dollars the bank uses the lower figure.

Why are bank holidays excluded when finding the spot date?

Settlement can only happen on working days. When you count the two days for a spot (T+2) transaction. Intervening bank holidays do not count. So the value date shifts to the next available working day.

Why is the previous month’s forward premium used for a delivery window?

If an exporter can deliver on any day within a month. The bank prices the contract using the premium of the last fully completed month before the window begins. This protects the bank for the entire delivery period.

Is the exchange-rate case study important for the CAIIB BFM exam?

Yes. It is a recurring, high-scoring numerical area. Once you internalise the value-date rules. The buy-low-sell-high principle and the forward-premium logic, these questions become near-guaranteed marks. For exact patterns and weightage, confirm on the latest official IIBF notification.
