Even in times of uncertainty, some investments are seen as being crisis-proof. For example, the Swiss franc is a popular currency worldwide when the global markets are turbulent. Swiss federal government bonds are also seen as a very safe financial investment and there is great demand for them from investors, especially in times when the value of shares and other investments fluctuates significantly. Bonds issued by stable Swiss companies are another option for relatively safe investment. Gold is also generally seen as being a relatively secure investment which is why the gold price trend tends to be anti-cyclical. The price of gold often increases in times of uncertainty.
