Please check if my statement about the effect of relative interest rate rise & fall to the economy (particularly the IS graph) is correct or not and please explain thank you.

Relative interest rate Relative interest rate forecasts whether or not the real interest rate will have a favourable or negative impact on the economy. As a result, if relative interest rates rise, investor condence will decline since borrowing costs rise, as investment demands a higher rate of return, resulting in lesser investment spending. Alternatively, as relative interest rates fall, investor condence rises as borrowing costs fall, resulting in more investment. i LM i LM /' / BP BP IS1 IS IS y IS1 y Rise in relative interest rate Fall in relative interest rate
