The best long-term indicator

OANDA:USDCAD   U.S. Dollar / Canadian Dollar
One of the main economic indicators for currency valuation is the real interest rate differential between the two countries / currencies.

The large flows of fixed income always go to where there is the highest real yield, interest rate discounted from inflation . The carry trade.

It is possible to see in the USDCAD example on the graph the great correlation between the interest rate differential and the appreciation / depreciation of each currency.

Currently, this indicator does not seem to make much sense due to extremely low inflation and low interest rates in the worldwide. However, the big draw is to know where the economic recovery will be faster, will create more jobs and income, will lead to an increase in inflation and consequently to an increase in interest rates and currency appreciation.

Make your bets!

I would bet on Australia and Europe, maybe that's why the dollar is so weak.
