Definition of Net Interest Rate Differential (NIRD) 🏦§

The Net Interest Rate Differential (NIRD) is the total difference in interest rates between two distinct national economies, specifically applicable in the context of currency pairs in the foreign exchange (forex) market. It encompasses the after-tax and after-fee differences between the interest earned on one currency and the interest paid on another while holding a currency pair position.

Formula for NIRD ⚖️§

$NIRD = (i_A - i_B) - \text{Fees} - \text{Taxes}$ Where:

$i_A$ = Interest rate of currency A
$i_B$ = Interest rate of currency B

NIRD vs. Interest Rate Spread§

Net Interest Rate Differential (NIRD)	Interest Rate Spread
Deals with after-tax, after-fee interest differences	Represents the difference between two nominal interest rates
Used primarily in forex trading and carry trades	Commonly used in the context of lending and borrowing
Can affect trading decisions on carry trades	Influences market liquidity and lending dynamics
Affects profit or loss when holding currency positions	Shows profitability of various financial instruments

Examples of NIRD in Action 🌍§

Suppose a trader is long on the NZD/USD pair. If the interest rate for NZD is 3% and for USD is 1%, and considering 0.5% in fees and 0.2% in taxes, the NIRD would result in: $NIRD = (3% - 1%) - 0.5% - 0.2% = 1.3%$
If a trader holds a positions in EUR/JPY, with EUR offering a 0.5% interest rate while JPY offers -0.1% with negligible fees and taxes, the NIRD would be: $NIRD = (0.5% - (-0.1%)) - 0% - 0% = 0.6%$
