In the emerging economies, performance remained uneven, while growth continued to cool in China. The global economy is expected to gather pace again, reinforced by expansionary monetary policy around the world and ongoing low oil prices. For instance, after a disappointing first  BIS central bankers’ speeches  1  quarter, the two large economies, the US and China, are starting to show signs of improvement. Nonetheless, uncertainty about the future development of the global economy remains high. Various risks – first and foremost the difficult financial situation in Greece and geopolitical tensions – could jeopardise the recovery. Swiss economic outlook According to initial estimates, Switzerland’s real GDP declined slightly in the first quarter. As expected, goods exports suffered from the strong Swiss franc appreciation, but also from a downturn in global trade. Domestic demand, by contrast, developed robustly. Having said this, the situation varies considerably from one industry to another. Profit margins are under significant pressure in several sectors, and this is forcing companies to take steps to reduce production costs and raise efficiency. Against this backdrop, unemployment has increased slightly on a seasonally adjusted basis. Over the coming months, the global economic recovery is likely to lead to a gradual upturn in demand for Swiss products; this will cushion the impact of the exchange rate shock somewhat. As the global economy gathers momentum, we expect Switzerland to return to positive growth in the second half of the year. The SNB continues to anticipate growth of just under 1% for 2015 as a whole.

The current financial turmoil is here to remind us that financial innovation is not a smooth process. An appropriate knowledge of the mechanisms through which monetary policy affects the economy is of crucial importance for central banks. Financial innovation affects these mechanisms by altering the channels through which monetary policy operates. Drawing on some lessons from the current turmoil, I would like to make four points. First, securitisation has created new uncertainties in the transmission channels of monetary policy. It may have weakened some channels and strengthened some others. At least in normal times, financial innovation significantly weakens the bank-lending channel. Securitisation gives firms broader access to capital markets and, as such, makes them less dependent on bank funding. Similarly, banks may be more able to issue debt securities and less dependent on the constraint of funding themselves with secured deposits. At the same time, however, securitisation strengthens the “direct” transmission channel through which interest rates operate, since a great number of financial intermediaries are more dependent on liquidity and on its price. Second, financial innovation – to the extent that it makes it easier to take risks and encourages the “search for yield” – may have increased the impact of monetary policy because, in such an environment, risk premia are highly procyclical and move in tandem with interest rates. Third, this same procyclicality of “risk taking” can lead to booms and busts, when investors’ appetite for risk changes.
