Exchange Rate Mechanism - Calculations
June 17, 2023, 8:10 a.m.- Where is the wholesale market of forex?
- The wholesale market is also called as Inter-Bank market.
- It lies in the dealing room of the Bank’s Treasury.
- The transactions taking place between the banks or financial institutions are called as wholesale transactions or inter-bank transactions.
- 1 $ = 82.44 – this is called as Average interbank rate.
- 1 $ = Rs. 82.43/82.45
- 1 $ = Rs. 82.43/45
- Rs. 82.43 is called as Bank’s buying rate of Dollar or also called as Bid Rate.
- Rs. 82.45 is called as Bank’s selling rate of Dollar or also called as Offer Rate or Ask Rate.
- The Logic is Buy Low and Sell high, then only the trader can make profit.
- The difference between Buying Rate and Selling rate is called as Spread.
- From the spread itself, we can come to know the depth of the market.
- Our Market today:
- 1 $ = 82.43/45, the spread is 2 paise.
- $ is called as the Base Currency, it will never move.
- Rupee is called as the Variable Currency, because $ makes the rupee to go up and down.
- The WTO approved countries are about 190 in the world. Nearly 95% of the countries follow $ as the base currency.
- In Singapore the $ rate is:
- 1$ = 1.3433/35 SGD, the difference is called as 2 pips.
- In the inter-bank or wholesale market, the minimum marketable lot size is $ 5,00,000 or also called as $ 500th.
- For example, Mr. X is exporter and has exported goods worth $ 200th
- B category branch where the exporter has got his account has securitized the export documents and it is in order.
- Then What B Category will do:
- Any foreign exchange rate, we have to see from Dealing Room point of view;
- What is today’s inter-bank rate:
- 1 $ = 82.43/45.
- As per the logic, we have to take the buying rate of dealing room, that is Rs. 82.43.
- B category has to load some margin for the work carried out for the exporter.
- Assuming, B Category loads a margin of 2 paise per $, then the export merchant rate would be:
- Inter-Bank Rate is : Rs. 82.43
- Less Margin: 0.02
- Export Rate is: Rs. 82.41
- How much rupee would be credited to the account of the exporter?
- $ 200th x Rs. 82.41 = Rs. 1,64,82,000 would be credited to the exporter’s account.
- What is margin or profit earned by bank in the export transaction?
- Rs. 0.02 x $ 200th : Rs. 4,000/-
For example, Mr. Y is importer and importing some goods from abroad for $ 200th
- B category branch where the importer has got his account has securitized the import documents and it is in order.
- Then What BCategory will do:
- Any foreign exchange rate, we have to see from Dealing Room point of view;
- What is today’s inter-bank rate:
- 1 $ = 82.43/45.
- As per the logic, we have to take the selling rate of dealing room, that is Rs. 82.45.
- B category has to load some margin for the work carried out for the importer.
- B category is out of funds by Rs. 82.45
- Assuming, B Category loads a margin of 3 paise per $, then the import merchant rate would be:
- Inter-Bank Rate is : Rs. 82.45
- Add Margin: 0.03
- Export Rate is: Rs. 82.48
- How much rupee would be debited to the account of the importer?
- $ 200th x Rs. 82.48 = Rs. 1,64,96,000 would be debited to the importer’s account.
- What is margin or profit earned by bank in the import transaction?
-
- Rs. 0.03 x $ 200th: Rs. 6,000/-
-
- Simple thumb rules:
- For exporters or inward remittances:
- Take the less rupee from the inter-bank quote.
- Export or inward remittance margin is deducted.
- Exporter’s rupee account is credited.
- For importers or outward remittances:
- Take the higher rupee from the inter-bank quote.
- Import or outward remittance margin is added.
- Importer’s rupee account is debited.
- For exporters or inward remittances:
- Let us do a problem:
- Today’s inter-bank quote is:
- 1 $ = 81.92/94
- Exporter has submitted export document for $ 500th. Margin to be loaded is 3 paise per $.
- Importer has submitted import document for $ 400th. Margin to be loaded is 4 paise per $.
Your questions:
-
- What is the inter-bank export rate?
- 1 $ = Rs. 81.92
- What is the merchant export rate?
- 1 $ = Rs. 81.89
- How of rupee would be credited to the account of the exporter?
- Rs. 81.89 x $ 5,00,000 = Rs. 4,09,45,000
- What is the inter-bank import rate?
- Rs. 81.94
- What is the merchant import rate?
- Rs. 81.98
- How of rupee would be debited to the account of the importer?
- Rs. 81.98 x $ 400,000 = Rs. 3,27,92,000
- What is the total margin earned by the Bank on the above two transactions?
- On export: 0.03 x $ 500th: Rs. 15,000/-
- On import: 0.04 x $ 400th: Rs. 16,000/-
- Total margin earned: Rs. 31,000/-.
- Cross Currency:
- What is cross currency internationally?
- In a currency pair, $ leg will be absent.
- 1 Euro = 150.02 Yen.
- In a currency pair, $ leg will be absent.
- What is cross currency in India?
- In a currency pair, rupee leg will be absent.
- 1$ = 1.3433/35 SGD = also called as direct quote.
- In a currency pair, rupee leg will be absent.
- Some countries, they think they are superior to $.
- 1 Euro = 1.0746/48 $, the difference is 2 pips = Indirect quote.
- What is the inter-bank export rate?
Next Problem:
- For example, Mr. X is exporter and has exported goods worth SGD 200th:
- Today’s Forex rates are:
- 1 $ = 81.92/94
- 1$ = 1.3433/35 SGD
- B category branch where the exporter has got his account has securitized the export documents and it is in order.
- Then What B Category will do:
-
- Any foreign exchange rate, we have to see from Dealing Room point of view;
- While doing exchange rate mechanism, it should be carried out from base currency perspective:
- 1 $ = 81.92 INR
- 1 $ = 1.3435 SGD
- We have to find out how rupee, the dealing room has to give to the exporter for 1 SGD.
- 1.3435 SGD = Rs. 81.92
- 1 SGD =?
- Rs. 81.92/1.3435 SGD = Rs. 60.975 or Rs. 60.98
- Less assuming a margin of: 0.02
- Exporter Merchant Rate: Rs. 60.96.
- Rs. 60.96 xx SGD 200TH: Rs. 1,21,92,000 would be credited to the account of the exporter.
- Margin earned by the Bank: 0.02 x SGD 200TH: Rs. 4,000/-.
Next Problem:
- For example, Mr. Y is importer and he is importing goods worth CAD 200th.
- Bank is loading a margin of 3 paise per CAD.
- Solution:
- Today’s Forex rates are:
- 1 $ = 81.92/94
- 1$ = 1.3338/40 CAD.
- B category branch where the importer has got his account has securitized the import documents and it is in order.
- Then What B Category will do:
-
- Any foreign exchange rate, we have to see from Dealing Room point of view;
- While doing exchange rate mechanism, it should be carried out from base currency perspective:
- 1 $ = 81.94 INR
- 1 $ = 1.3338 CAD
- We have to find out how rupee, the dealing room has to recover from the importer for 1 CAD.
- 1.3338 CAD = Rs. 81.94
- 1 CAD =?
- Rs. 81.94/1.3338 CAD = Rs. 61.43 or Rs. 61.43
- Add assuming a margin of: 0.03
- Exporter Merchant Rate: Rs. 61.46.
- Rs. 61.46 x CAD 200TH: Rs. 1,22,92,000 would be debited to the account of the importer.
- Margin earned by the Bank: 0.03 x CAD 200TH: Rs. 6,000/-.
Next Problem:
- Today’s Forex rates are:
- 1 $ = 81.92/94 (Direct Quote)
- 1 GBP = 1.2571/73 $ (Indirect Quote)
- 1 Euro = 1.0746/48 $ (Indirect Quote)
- Exporter has submitted export bill for GBP 500th and margin to be loaded is 0.05% and you have to give 4-digit quote.
- B category branch where the exporter has got his account has securitized the export documents and it is in order.
- Then What B Category will do:
-
- Any foreign exchange rate, we have to see from Dealing Room point of view;
- While doing exchange rate mechanism, it should be carried out from base currency perspective:
- 1 $ = 81.92 INR
- 1 GBP = 1.2571 $
- We have to find out how much rupee, the dealing room has to give to the exporter for 1 GBP.
- 1 $ = Rs. 81.92
- 1.2571 $ =?
- Rs. 81.92 x 1.2571 $ = Rs. 102.9816
- Less 0.05% = 0.0515 (102.9816 x 0.05/100)
- Exporter Merchant Rate: 102.9301
- Rs. 102.9301 x GBP 500th: Rs. 5,14,65,050 would be credited to the account of the exporter.
- Margin earned by the Bank: 0.0515 x GBP 500TH: Rs. 25,750/-.
Next Problem:
- Importer has submitted import bill for Euro 500th and margin to be loaded is 0.05% and you have to give 4-digit quote.
- Today’s Forex rates are:
- 1 $ = 81.92/94 (Direct Quote)
- 1 Euro = 1.0746/48 $ (Indirect Quote)
- Then What B Category will do:
- Any foreign exchange rate, we have to see from Dealing Room point of view;
- While doing exchange rate mechanism, it should be carried out from base currency perspective:
- 1 $ = 81.94 INR
- 1 Euro = 1.0748 $
- We have to find out how much rupee, the dealing room has to recover from the importer for 1 Euro.
- 1 $ = Rs. 81.92
- 1.0748 $ =?
- Rs. 81.94 x 1.0748 $ = Rs. 88.0691
- Add 0.05% = 0.0440 (88.0691 x 0.05/100)
- Exporter Merchant Rate: 88.1131
- Rs. 88.1131 x Euro 500th: Rs. 4,40,56,550 would be debited to the account of the importer.
- Margin earned by the Bank: 0.0440 x Euro 500TH: Rs. 22,000/-.
- In forward contract, the rate difference arises out of interest rate differential.
- Let us assume today’s average rate is 1 $ = Rs. 82/-
- One year T.bill in US is available at the rate of 3%.
- One year T.bill in India is available at the rate of 6%.
- From the above input arrive at the year $/rupee parity.
- Long cut:
- (82 x 1 x 6)/ (100 x 365) = Rs. 4.92
- (1 x 1 x 3)/ (100 x 360) = 1.03 $
- From this, arrive at 1 $ rate: (82 + 4.92)/ (1.03)
- 86.92/1.03 = Rs. 84.39 per $
- Short cut:
- 82 x (1.06/1.03)
- 82 x 1.0291 = Rs. 84.39 per $
Problem:
-
- Assume today is 5th May, 2023
- One exporter wants to book a forward contract for his $ receivable on 30th April, 2024. Assuming bank is loading a margin of 2 paise per $, what rate bank would quote for him?
- Today’s Inter-Bank Rate: Rs. 81.71
- Add premium for 30/04: 3.15
- Interbank forward rate: Rs. 84.86
- Less Margin: 0.02
- Merchant Forward Rate: 84.84
Problem:
- One importer wants to book a forward contract for his $ payable on 29th February, 2024. Assuming bank is loading a margin of 2 paise per $, what rate bank would quote for him?
- Today’s Inter-Bank Rate: Rs. 81.73
- Add premium for 29/02: 2.63
- Interbank forward rate: Rs. 84.36
- Add Margin: 0.02
- Merchant Forward Rate: 84.38
Next Problem: Broken delivery:
- One exporter wants to book a forward contract for his $ receivable on 16th April, 2024. Assuming bank is loading a margin of 2 paise per $, what rate bank would quote for him?
- Today’s Inter-Bank Rate: Rs. 81.71
- Add premium for 31/03: 2.88
- Add premium 16/04: 0.14
- Interbank forward rate: Rs. 84.73
- Less Margin: 0.02
- Merchant Forward Rate: 84.71
- Problem:
- One importer wants to book a forward contract for his $ payable on 09th February, 2024. Assuming bank is loading a margin of 2 paise per $, what rate bank would quote for him?
- Today’s Inter-Bank Rate: Rs. 81.73
- Add premium for 31/01: 2.36
- Add premium 09/02: 0.08
- Interbank forward rate: Rs. 84.17
- Adds Margin: 0.02
- Merchant Forward Rate: 84.19
- Above are called as Fixed date deliveries. In case of fixed date deliveries, on due date some problem can arise, such as strike, lock out etc.
- Exporters and importer approached FEDAI, which Self-regulatory organization.
- So, FEDAI came out with an idea of booking forward contracts with option period.
- FEDAI permits a maximum option period of 1 month.
- Examples:
- It can be full month February, 2024
- It can be from 15/3/2024 to 14/04/2024
- Within one month, booking can be done as follows:
- 1/1/2024 to 10/01/2024
- 18/2/2024 to 25/02/2024
- Any forward contract with option period will have two legs:
- One is called as early delivery.
- Another is called late delivery.
- In case, forward contract is booked with full month option period of say, March, 2024:
- Early delivery will be 1st March, 2024
- Late delivery will be 31st March, 2024.
- In case of exporters, go for early delivery and for importers go for late delivery.
Problem:
-
- One exporter wants to book a forward contract for his $ receivable on Full month April, 2024. Assuming bank is loading a margin of 2 paise per $, what rate bank would quote for him?
- What would be the early delivery: 1/04/2024
- Late delivery would be: 30/04/2024.
- So, in case of exporters go for early delivery that is, 1/04/2024
- Today’s Inter-Bank Rate: Rs. 81.71
- Add premium for 31/03: 2.88
- Add for 1st April 0.01
- Interbank forward rate: Rs. 84.60
- Less Margin: 0.02
- Merchant Forward Rate: 84.58
Problem:
-
- One importer wants to book a forward contract for his $ payable on Full month April, 2024. Assuming bank is loading a margin of 2 paise per $, what rate bank would quote for him?
- What would be the early delivery: 1/04/2024
- Late delivery would be: 30/04/2024.
- So, in case of importer go for late delivery that is, 30/04/2024
- Today’s Inter-Bank Rate: Rs. 81.73
- Add premium for 30/04: 3.17
- Interbank forward rate: Rs. 84.90
- Add Margin: 0.02
- Merchant Forward Rate: 84.92
- In case of fixed date delivery, the rate is efficient but customers run the risk of non-performing.
- In case of forward contract with option delivery, the rate is inefficient, but customers do not run the risk of cancellation of contract.
