Last week I wrote about country ratings and the impact they have on the economy and your portfolio.

This also has an immediate impact on exchange rates.

A really important topic in my world as a traveller, I always feel the change in exchange rates instantly.

I remember the first time the finance minister in South Africa was replaced - I was living in Goa, India. Up until that moment ZAR1 would give me Rs5, but then suddenly overnight ZAR1 could only get me Rs4. I was super upset.

Now in Dubai, something similar is happening, only now it’s crazier because the currency here is stronger and it’s one of the most expensive cities in the world.
