The end of an economic era may have occurred yesterday. The rise in interest rates announced by the US Federal Reserve Board looks like the turning point from the cheap money flooding through Western economies since the global financial crisis, to conditions more normal.
That means interest rates reaching levels allowing economies to grow without unleashing inflation. But it also means households carrying very high mortgages from the property boom generated largely by cheap money, will find interest rates rising in the new year.
The announcement by the Fed chairwoman, Janet Yellen, yesterday was significant not so much for its immediate rate increase as for her indication that three more rises in the US base rate can be expected during 2017. Markets had been expecting two at most. The change can be attributed directly to the response on US currency and stockmarkets to the election of Donald Trump.
The markets clearly believe Trump's promises to cut taxes and increase spending on infrastructure will give a hefty stimulus to the US economy next year, which does not really need it.
The economy has been recovering steadily in the two years since the Fed stopped "quantitative easing" and has seen an expansion of jobs this year.
