If interest rates rise, do real rates rise too? Let's distinguish them from 'nominal' rates

Hello, it’s Kira💅✨

You see ‘real interest rates’ in gold and FX news. Even though they have ‘interest rate’ in the name, they aren’t the same number as nominal interest rates. Today, I’ll break down the difference♡

■ Consider the outlook for prices as well
Nominal interest rates are rates before subtracting changes in prices. Future real interest rates are roughly calculated as ‘nominal interest rate minus expected inflation rate.’ This relationship is also explained in Bank of Japan documents.

■ What happens when the number you subtract changes?
The following are hypothetical numbers for explanation and do not represent current market rates.
If the nominal interest rate is 3% and the expected inflation rate is 2%, the real interest rate is roughly 1%.
Even if the nominal interest rate rises to 4%, if the expected inflation rate also rises to 3%, the difference remains roughly 1%.

Just saying ‘interest rates have risen’ doesn’t determine how real interest rates have changed📝

■ Match the time periods you compare
It’s important to match the periods, such as using a one-year price outlook for a one-year interest rate. You also want to distinguish between published inflation rates and future expectations.

When looking at gold or exchange rates, first check whether the news is referring to nominal or real rates. Price movements and profits aren’t determined by a single number alone.

Do you check which ‘interest rate’ the news is talking about? Let me know in the comments♡
