let’s say
2009 JPY/USD@90
2010 JPD/USD@100
from “complicated calculation,” we can see USD appreciate by 11.11%. And we will say JPY depreciate by the same extent 11.11%, right.
But actually, from strict calculation, yen only depreciate by 10%. One currency appreciate by A% against another currency, which does not mean another currency depreciate by the exact A%(approximately depreciate by A%.) right? |
