This would give the central Bank more control over monetary policy using the franc, but would also probably decrease demand for the franc, and slow down Swiss economic activity. I would imagine banks would start issuing non-reserve-backed loans in other currencies, and it would make lending just marginally more expensive (exchange rate is now an extra barrier to getting a loan).
