Bite Size Economics No. 1 (repost)
'interest is the price of risk'!
If a higher interest rate is being charged there is more risk of non-repayment.
This is why some people are charged more for loans & why some 'investments' are offered with higher interest rates.
Knowing this helps make sense of loans & investments; and is a useful scam warning
If an interest rate is out of line, ask yourself, why?
