Economist – When the going gets tough, investors buy two assets: gold and the Swiss franc. Gold’s all-time peak in real terms was in 1980 when inflationary fears were particularly intense. That followed a long period of Swiss-franc strength in the 1970s, which forced the government to impose negative interest rates in a bid to dissuade foreigners from opening bank accounts in the currency. With investors now worried about European sovereign debt and the crisis over the American debt ceiling, it is not surprising that both assets are popular again. Gold has been hitting nominal highs, while the Swiss franc has reached a record in real trade-weighted terms (ie, against the country’s trading partners). The Swiss have both a fiscal and a current-account surplus, a low inflation rate and a relatively low debt-to-GDP ratio.
