In Macroeconomics courses, the term 'interest rates' is often used without disambiguation between whether the interest rates if of the rate given in bank savings account / bonds or whether the rate is the interest rates in loans.
For example: Higher real interest rates in Country A attract Country B investors.
Now maybe, the higher interest rate is that given in A's Bonds, so B's investors buy these bonds.
Or, maybe, the higher interest rate is on loans, so B's investors like to give loans to people of A.
Probably, it is not mentioned because they are the same thing?? In both cases, you are still getting the interest rates from the A, in case 1, from A's government, in case 2, from A's people.
In general, if not mentioned what type of interest rate, what does it stand for or does the difference not matter?
