BIS Review 99/2007  3  Rapid appreciation in the exchange value of the currency renders part of the domestic industries less competitive in the global markets. It is true that with this appreciation, commodity imports such as fuel and energy as well as metal and raw materials have become more affordable despite rising world price trends. But these benefits are spread-out while the cost is centered on labor-intensive, high domestic-content primary sectors, such as agriculture and low-end manufacturing. As a result, even for net primary commodity importing economies, the nature of the problem is as much political economy as it is economic. There are strong and vocal constituencies in emerging markets that are averse to currency appreciation and part of them averse to variability in the exchange rate itself. Meanwhile, hot money, or indeed large inflows in general, can fuel asset prices and encourage excessive risk-taking behavior. Central banks may wish to counter that excess in the interest of financial stability. If the central bank chooses to maintain a high interest rate stance, the pressure on the currency to appreciate will likely mount. Not unlike today’s political economy in advanced countries, emerging market politics also risks being less favorable to openness, but more partial to protection of selected industries or protectionism in general.

The unique nature of the COVID-19 pandemic has also caused an unprecedented shock to the real economy. To mitigate this shock, central banks – in cooperation with the fiscal authorities – have created new instruments. The SNB during the COVID-19 crisis: same role, new tools Given the nature of the crisis, an important part of the policy response was to address the strains on the corporate sector, particularly among small and medium-sized enterprises (SMEs). In Switzerland, 99 percent of all firms are SMEs and they employ some 67 percent of the labour force. The lockdown measures resulted in a sudden stop for many businesses. There was real concern that economically viable SMEs, in particular, could be 1  The US dollar swap basis is an indicator of US dollar funding costs in foreign exchange markets.

To address the problem, the Swiss Federal Council adopted a range of important measures, including the COVID-19 loan programme for companies. To be effective, financial support had to be fast and well targeted.
