A Central Banking Domino Effect Is in Motion

Policy U-turns from the Fed and ECB are cascading around the world

Abrupt changes in the policies of the world’s largest central banks have rippled through smaller economies, leaving them with the prospect of low and even negative interest rates for years to come despite having mostly healthy economies.

The danger is that these easy-money policies could fuel destabilizing bubbles in real estate and other asset markets. They may also leave banks with little ammunition to respond to the next economic downturn.

Economies like Switzerland’s, whose central bank signaled no change in its negative-rate policies for years to come, are small compared with the U.S. and eurozone. Still, they are home to major global banks and companies that are sensitive to exchange rates and financial conditions. With financial markets so interconnected, problems in small countries can quickly spread to larger ones.

.. The Swiss National Bank said Thursday that it would keep its policy rate at minus 0.75%, where it has been since January 2015, and reduced its inflation forecast to 0.3% this year and 0.6% in 2020. The SNB cited weaker overseas growth and inflation and “the resulting reduction in expectations regarding policy rates in the major currency areas going forward.”

.. Here’s why Fed and ECB decisions matter for countries that don’t use the dollar or euro: Switzerland and countries near the eurozone but not part of it—like Sweden and Denmark—rely on the bloc for much of their exports and imports. That makes growth and inflation highly dependent on the exchange rate. Central-bank stimulus tends to weaken a country’s exchange rate, so when the ECB embraces easy-money policies as it did two weeks ago it tends to weaken the euro against other European currencies such as the Swiss franc. Because the ECB is so large, Switzerland and others can do little to offset it.

.. “They are hostage to the fortunes of what the ECB does,” said David Oxley, economist at Capital Economics.

.. “The gravity pull is very strong” from the Fed and ECB, said Sebastien Galy, macro strategist at Nordea Asset Management. “The consequence is [non-euro central banks in Europe] mostly end up importing policy from the ECB, so you end up with housing bubbles and a misallocation of capital.”
