Franc
The Swiss franc (ISO code: CHF or 756), which appreciated significantly against the new European currency from April to September 2000, remains one of the world's strongest currencies, worth today around five-sixths of a euro. The Swiss franc is used in Switzerland and in Liechtenstein. Liechtenstein retains the ability to mint its own currency, the Liechtenstein franc, which it does from time to time for commemorative or emergency purposes.
Federal budget of Switzerland
The budget principles are defined by the Swiss Constitution and have been restated most recently in the 1999 fiscal guidelines of the confederation. In 2010 the federal budget of Switzerland had a size of 62.8 billion Swiss francs, which is an equivalent 11.35% of the country's GDP in that year. In 2014 the federal budget of Switzerland had an estimated size of 66.353 billion Swiss francs, which is an estimated equivalent 10.63% of the country's GDP in that year.
Note that the Swiss "federal" budget only comprises 31.7% of Swiss public expenditure, the rest being managed by the cantons and the municipalities directly.
