Up, up and away - As the Fed raises rates, Janet Yellen s legacy is pondered

Donald Trump has the chance to mould America s central bank

THIRD time lucky. In each of the past two years, the Federal Reserve has

predicted multiple interest-rate rises, only to be thrown off-course by events.

On March 15th the central bank raised its benchmark Federal Funds rate for the

third time since the financial crisis, to a range of 0.75-1%. This was, if

anything, ahead of its forecast, which it reaffirmed, that rates would rise

three times in 2017. Lift-off is at last an apt metaphor for monetary policy.

But as Janet Yellen, the Fed s chairwoman, picks up speed in terms of policy,

she must navigate a cloudy political outlook. The next year will define her

legacy.

Ms Yellen took office in February 2014 after dithering by the Obama

administration over a choice between her and Larry Summers, a former treasury

secretary. Left-wingers preferred Ms Yellen, in part because she seemed more

likely to give jobs priority over stable prices. Indeed, Republicans in

Congress worried that she would be too soft on inflation. The Economist called

her the first acknowledged dove to lead the central bank.

Today Ms Yellen looks more hawkish certainly than Mr Summers, who regularly

urges the Fed to keep rates low. Headline inflation has risen to 1.9% a year;

but excluding volatile food and energy prices it is a bit stuck, at around

1.7%. Yet Ms Yellen has not really changed her plumage. As expected, she has

consistently given high weight to unemployment. Before her appointment, when

joblessness was high, she wanted the Fed to promise to keep rates low for

longer than it then planned. Now that unemployment is just 4.7%, she is keener

to raise rates than those who worry about stubbornly low inflation.

In March 2015 Ms Yellen argued that, were the Fed to ignore a tight labour

market, inflation would eventually overshoot its 2% target. The Fed might then

need to raise rates sharply to bring it back down, risking a recession and

hence more unemployment. Better to lift rates in advance.

Unemployment, however, was already down to 5.5%. So most rate-setters had

started 2015 forecasting a rapid lift-off, taking rates up by at least one

percentage point over the year. But inflation remained strangely tepid (see

chart). Cheap oil and a strong dollar were partly to blame. But wages also

seemed stuck. Ms Yellen and her colleagues deduced that unemployment could

safely fall a bit further.

In the end, they raised rates once in 2015, in December. Again, they forecast

four rate rises for the next year. This time they were delayed by worries over

the global economy (China wobbled early in 2016). Officials also began to see

lower rates as a permanent feature of the economy. Today, the setters think

rates will eventually stabilise at 3%, down from a forecast of 4% when Ms

Yellen took office.

Ms Yellen s Fed, then, has proved very willing to change course. And this time

the Fed is speeding up, rather than postponing, rate rises. Three factors are

at play. First, the global economy has been reflating since the middle of 2016

(see article). Second, financial markets are booming, boosting the economy by

almost as much as three interest-rate cuts, by some estimates. Third, a fiscal

stimulus is looming. According to the Fed s model, a tax cut worth 1% of GDP

would push up interest rates by nearly half a percentage point. During his

campaign Donald Trump promised cuts worth nearly 3% of GDP, according to the

Tax Policy Centre, a think-tank.

Doves insist that the Fed risks halting an incomplete recovery. Before the

crisis of 2007-08, about 80% of 25-to 54-year-olds (the prime age population)

had jobs. Today the proportion is 78%. The difference is about 2.5m potential

workers, mostly not counted as unemployed because they are not looking for

work. Were the Fed to aim for the nearly 82% prime-age employment seen in April

2000, the jobs shortfall would look twice as high.

In October Ms Yellen wondered aloud whether a high-pressure economy , and a

resulting wage boom, might coax more people to seek work. This led to reports

soon corrected that she would let the economy overheat after all. In fact Ms

Yellen has long warned that many drivers of labour-force participation are

beyond the central bank s control. A gentle pickup in wage growth since

mid-2015 seems to support her view that unemployment is the best measure of

economic slack.

Rarely has unemployment been this low without inflation taking off. Once was in

the late 1990s, when Alan Greenspan, a former Fed chairman, correctly predicted

that rising productivity would stop a booming labour market from stoking

inflation. Jeffrey Lacker, chairman of the Richmond Fed, recently offered

another example. In 1965 unemployment fell to 4%, while inflation was only

1.5%. Yet prices took off in the years that followed: by 1968, inflation had

reached 4.3%.

That is what Ms Yellen wants to avoid. But the Fed has not often managed to

tighten monetary policy without an ensuing recession. Should she manage it, her

tenure will go down as a great success.

That is, if she has time to finish the job. Her term ends in February 2018. If

Mr Trump replaces her, she could stay on as a board member. But she would

probably leave. So would Stanley Fischer, the Fed s vice-chairman, whose term

expires four months later. Two of the Fed s seven seats are already vacant, and

Daniel Tarullo, the de facto vice-chairman for regulation, goes in April. So Mr

Trump may be able to appoint five governors, including the chairman, within 18

months of taking office.

What then for monetary policy, and for Ms Yellen s legacy? During his campaign,

the president attacked the Fed for keeping rates low and said he would replace

Ms Yellen with a Republican. Mooted successors include Glenn Hubbard, who

advised George W. Bush; Kevin Warsh, a former banker and Fed governor; and John

Taylor, an academic and author of a rule, named after him, for setting interest

rates.

A kettle of hawks

All these potential successors are monetary-policy hawks. Some versions of the

Taylor rule, for example, call for interest rates more than three times as high

as today s. Mr Trump, who promises revival and 3.5-4% economic growth, might

not like the sound of that. If, like most populists, he wants to avoid tight

money, he could appoint someone malleable to the Fed. But that would also be

risky. One cause of the inflationary surge of the 1960s, notes Mr Lacker, was

political pressure to keep policy loose even after ill-timed tax cuts. On one

occasion, President Lyndon Johnson summoned the Fed chairman, William McChesney

Martin, to berate him for raising interest rates (and to drive him around his

ranch at breakneck speed).

A simpler way to keep hawkish Republicans at bay would be to reappoint Ms

Yellen. With Mr Tarullo out of the frame, Mr Trump would still be able to

impose his deregulatory agenda, yet keep faith with Ms Yellen to set monetary

policy. Senators would struggle to come up with reasons not to reappoint a

central-bank chairwoman so close to achieving her goals. Bill Clinton and

Barack Obama reappointed incumbent Republican chairmen. It might be in Mr Trump

s interest to reciprocate.
