It is bad for a national currency, but that is not what I was talking about. I was talking about a reserve currency, like gold represents in our world economy (which is also deflationary).
When a country wants to buy oil for its economy, the oil price is set in the worlds reserve currency, USD. So the fluctuations between the USD and some given country, or the inflation of the USD will either hurt or help that country (but is always good for the US as the demand is high for that currency, keeping the demand strong). This is why countries/companies buy oil with gold sometimes, this is why countries hold gold to hedge inflation in a foreign currency they must rely on.

National currency (eg. USD) => Inflation bad.
Supranational currency (eg. gold) => Deflation good.
