Interest Rate Differential (IRD)

What is Interest Rate Differential (IRD)?

An Interest Rate Differential (IRD) is the gap between the interest rates of two similar financial instruments. In essence, it’s the financial world’s way of comparing apples to oranges – or more aptly, comparing two apples at different prices!

IRD is a crucial concept in forex trading, where traders use it to price forward exchange rates based on interest rate parity. So, if you’re planning to carry your currency in one country and exchange it back in another, you’ll need to keep this little number in mind.

Important Notes:

Interest rate differentials are often applied in fixed income, forex, and lending markets.
They’re integral for calculating the potential profitability of a currency carry trade, which involves borrowing in a currency with a lower interest rate and investing in a currency with a higher rate. Effortlessly outsmarting the market, one trade at a time!
