Anita Greil: Switzerland is considering capital controls to fight a sharp rise in the Swiss franc in the event of a euro-zone collapse.
……In the 1970s, Switzerland used such extreme measures to curb excessive demand for its currency. The country prohibited foreign investments in Swiss securities and real estate, and introduced negative interest rates on foreign deposits. Both tools failed to stem the Swiss franc’s rise, which only halted after the central bank introduced a temporary peg to the deutsche mark, Germany’s currency at the time.
