Answer:
They would rise
Step-by-step explanation:
Although interest rates alone do not determine the value of foriegn exchange rates, what is true is that ''the higher interest rates, the higher the attraction of foreign investment, which increases the 'demand for' and 'value of' the home country's currency.
Therefore pegging the euro to the pound which is a higher currency will imply that the value of the euro is increasing and the value of interest rate in Europe will rise accordingly.
