Answer:
A. We should expect higher interest rates and lower stock prices.
Explanation:
Producer price index refers to the price that producers recieve for their products. When there is an increase in PPI it means producers are receiving more revenue.
Increased revenue will result in more money in circulation. To regulate the excess money the monetary authorities will increase interest rate to reduce borrowing and by extension money in the economy.
Because there is now a need to get more funds by the companies, they will lower share prices to make them attractive to prospective investors.
