6  Admittedly, some new technological developments (such as digitalisation, robotics and artificial intelligence) could be a source of faster productivity growth. And plausibly, population ageing may actually promote automation. But eventually automation can only progress insofar as new ideas (so-called product innovation) emerge. Whatever the net effect on productivity, with the evidence we now have on the association between demography and growth in advanced economies in recent decades, we should not rule out the possibility that population ageing might significantly decrease potential output growth. Given population projections, extrapolating the observed association into the coming decades yields declines of output growth of about 1 percentage point (pp) until 2030, and close to 2 pp in countries where the demographic transition will accelerate in the years ahead. And recent observations on productivity growth are not very encouraging. Whatever the measurement used (either labour productivity or total factor productivity) there is a clear productivity slowdown in most advanced economies during the last two decades, even though total factor productivity growth has recovered somewhat in the last one. There is some discussion about to what extent this global productivity trend is due either to missmeasurement, to the delay in the diffusion of the new technologies and of their potential effects, or to more fundamental reasons, such as a slower innovation rate. Nevertheless, we cannot take for granted that productivity growth could compensate for the negative effects of population ageing on potential growth. 7  Population ageing may also affect trend inflation.
In order to supply liquidity to companies quickly and with minimum red tape, the Federal Council drew up an aid package, together with the SNB, the Swiss Financial Market Supervisory Authority FINMA, and the banks. Under this programme, the banks grant loans to companies. The Confederation assumes the default risk and the SNB provides the banks with liquidity through a new refinancing facility. Thanks to this facility, banks can refinance these loans favourably at the SNB policy rate of  Page 2/5  –0.75%. All indications are that the supply of credit and liquidity to small and medium-sized enterprises in Switzerland is currently working well. Another feature of the financial centre is that, in carrying out their activities, banks and insurance companies themselves add value and create jobs. The financial sector is an important employer in Switzerland, with around 218,000 full-time positions in 2018. In that year, it generated a nominal gross value added of around CHF 63 billion, or almost 10% of GDP. 1 Its size, however, means that both positive and negative developments in the sector have a particularly strong effect on Switzerland. The SNB, too, is dependent on an efficient and effective financial sector. This is because by granting loans, the commercial banks transmit our monetary policy to the Swiss economy. And by participating in the Swiss franc repo market, insurance companies, too, play a role in Swiss money market pricing. The financial sector thus makes an important contribution to the transmission of our monetary policy.
