Whilst users of Libor clearly benefit from this concentration of liquidity, the flipside is that it makes the adoption of alternatives to Libor a very challenging task. These network effects are reinforced by market convention, accounting practices, and the frictional costs of changing firms’ systems and risk models. And use of Libor is perpetuated by the need to hedge and manage legacy positions. Overall, there is substantial inertia in the use of Libor. The case for change The financial system’s Libor dependency matters for two reasons. First, as I have argued, in many applications users would be better served by a near risk-free rate: the bank credit component of Libor is in these cases neither necessary nor appropriate. Derivatives markets in particular could be more effective if there were liquidity in alternative reference rates. The prospect of improved market effectiveness might not, on its own, justify change. A second factor adds powerful impetus to the case for change. As the Governor emphasised, the truth is that the term deposit markets which underpin Libor fixings are no longer a liquid source of bank funding. Even a reformed Libor will need to rely on expert judgement to supplement transactional data. That is not a desirable state of affairs.
Although economic developments are favourable, inflationary pressures remain low. Moreover, the Swiss franc remains highly valued and the situation on the foreign exchange market is still fragile. Against this backdrop, the contours of a ‘new normal’ are emerging for central banks. While there are still many significant unknowns in the political, geopolitical and economic arenas, one thing is certain: the environment in which the central banks operate has evolved considerably, mainly due to structural changes. Some of these changes had already begun well before the crisis, but they have accelerated in the intervening period. I am thinking here of the digitalisation of the economy, for example, as well as the emergence of new technologies on the financial markets. In this speech, I would like to outline how the SNB has had to adapt – and continues to adapt – to make sure it is always in a position to fulfil its mandate.
