I doubt it. If they (the Swiss) don't keep on par with the euro, their exports and economy are toast.
Are you telling me the Swiss stopped backing the Franc with gold so Franc could move in sync with Euro?
All I know is currency with 40% gold backing would be in tremendous demand today. And the Franc had that backing for ages, dropped it in 2000
There are international agreements for central banks to dump gold, and the Swiss were part of that. But yes, partly because they can't afford to let their currency get too overvalued WRT the euro. There's a huge amount of day-to-day trade into Germany and France and it would kill Swiss manufacturers and merchants to let the Franc get too high.
