That's a myth, even when AUD was at its peak in the last 4 years or so the cost of living was skyrocketing at a hyper rate, inflation was rampant in Australia yet the Analysts and experts kept claiming how strong the AUD is, ignoring the fact purchasing power of AUD is very poor.

True measure of a stable currency imo is its purchasing power and v low inflation rate.

What good does it do for a person if his local currency goes up in value against other currencies but food and living prices go up every week. That scenario only benefits forex speculators
