- Go to http://www.oanda.com/currency/historical-rates/
- input `gold` (or another precious metal) as 'currency I have' and select '% change' instead of 'rate' (basket of commodities would be better but can't see anything like that available)
- now select various fiat currencies(or countries) you are interested in
You should be able to see the rate of inflation for the currencies you are viewing.
Speculation is mixed into the results but if you are comparing fiat currencies to one another this is reduced.
You can learn a lot from this graph.
- the Polish currency is bring printed even worse than Argentina
- quiet places like Switzerland tend to have low inflation rates
- USD is kind of average, fairing a lot better than the UK and the Euro
- Peru has a surprisingly low rate of inflation, as does Paraguay
- Libyan currencies seem to be doing just fine
You can cut through so much with this.
