SWAPS : Foreign Currency Swaps (Back to school)

A swap can be defined as simultaneously purchase and sale of equivalent amount of base currency for 2 different maturities, essentially its a simultaneously borrowing and lending of 2 currencies between 2 banks for specific period express in the form of purchase and sell transactions. The interest rate differential payable or receivables by one of the parties is factored into exchange rates applied for the 2 components of transactions. Therefore the difference between the buying and selling rate represents the interest rate differential and as defined as swap points.

Since the calculation of such differential is identical to calculations of forward margins. Forward margins are often termed as swap points. In the interbank market when banks provide a schedule of forward margins they in effect commit to undertake swaps at the differences indicated in table. For eg. If a bank provides the following

1USD = INR 55.525 – 55.575
Spot/OCT = 550 – 600
Spot/Nov = 1000 – 1050
Spot/Dec = 1400- 1450

It indicates their willingness to receive interest differential at the differences indicated on the ask side by buying & selling the base currency. Similarly They commit to pay the interest rate differential as indicated on the bid side by selling & buying the base currency.

In case of discount the vice versa will be applied of the table above.
