Final answer:
Monitoring the discount rate in relation to the 12-month moving average is more about tracking long-term exchange rate trends based on PPP, rather than providing accurate market predictions or short-term profitability insights.
Step-by-step explanation:
The question concerns the relationship between the discount rate and the 12-month moving average in predicting market trends. Monitoring the relationship between these two can indicate when the exchange rates are aligning with Purchasing Power Parity (PPP), as PPP suggests that exchange rates tend to move towards their equilibrium level over time. This adjustment accounts for changes in relative inflation rates, rates of return, and expectations regarding future interest rate and inflation changes. Central banks monitor exchange rates closely because their movements can influence aggregate demand and, if volatile, can disrupt international trade and financial stability. Therefore, we can surmise that monitoring the discount rate and 12-month moving average is a way to track longer-term exchange rate trends rather than providing accurate predictions or immediate profitability insights, as exchange rates often deviate from the PPP rate for short to medium periods before reverting back.
