Janet Yellen: A job well done

Today’s FOMC meeting was effectively the last act of Chair Janet Yellen, whose four-year term expires on 3 February. It is unusual for a one-term Chair not to be offered another term: Her tenure marks the shortest since G. William Miller’s ill-fated 17 month spell in 1978-79 and is indeed the second shortest since 1934 (beating the curtailed chairmanship of Thomas McCabe by a mere 14 days). The Fed Chair is in the gift of the President, so he is quite within his rights not to renew Yellen’s term. Nonetheless, I cannot help thinking that the Administration may be missing out by not giving her another four years.

Compared to her two immediate predecessors, Yellen came across as relatively unflashy and low key. She never sought the limelight in the same way as Alan Greenspan, and as good an academic economist as she is, Yellen never seemed to exude the same star quality as Ben Bernanke (maybe that’s an unfair characterisation but it is purely a personal impression). Yet in her understated way, Yellen has moved the dial further forward as the Fed seeks to move away from the crisis measures of 2008-09. In many respects, Bernanke’s inheritance was the result of years of loose monetary policy and a relaxed attitude to markets under Greenspan. Accordingly, much of his eight years were spent trying to prevent the economic and financial system from collapsing and Bernanke scored high marks for recognising the symptoms of the Great Depression and introducing a massive monetary expansion to combat it.

When Yellen took over in 2014 the economy was on a solid footing but monetary policy was still jammed in high gear, with interest rates at zero and the central bank balance sheet all but maxed out. The decision to start raising interest rates in late-2015 – the first increase in almost nine years – passed off without incident and an additional four increases, each of 25 bps, have not done any damage to the economy or to markets. Yellen also presided over the decision to start running down the Fed’s balance sheet although it will be up to her successor (Jay Powell) to fully implement it.

On the whole, it is likely that Yellen will be judged as a safe pair of hands who navigated the Fed through some difficult waters. It appears that her only failing was to be a Democrat at a time when an avowedly Republican Congress was in place. Whilst it was conservative lawmakers’ distrust of the Fed’s QE policy, fully supported at the time by Yellen, which counted against her, it is ironic that she has overseen the start of balance sheet unwinding – a process which has never been tested in the modern era.

As of next week, Jay Powell will be occupying the big chair and although he is widely seen as the continuity candidate, he may have his work cut out. For one thing, the US expansion is already long in the tooth, and assuming nothing goes wrong beforehand, May will mark the second longest expansion in recorded history. Quite how the Fed will respond if the economy starts to wobble may be an issue for the latter months of 2018. Then there is the question of how the Fed deals with any market wobble. For the last nine years, markets have generally only gone in one direction – upwards – but with valuations looking stretched it may not be too long before the bubble of optimism starts to deflate.

In the past, Greenspan and Bernanke were not averse to nudging monetary policy to help markets along. Whether Powell will act in the same way remains to be seen. But Janet Yellen will not be around for these issues to blot her copybook, which is a pity because the true test of how good central bankers are at their job is determined by their reaction to adversity. So we will never know how good she could have been, but as it is, Yellen can reflect on a job well done over the last four years.
