Stock market
investors have long understood that company guidance can be a double edged
sword. Investors use company guidance to
make inferences about trading conditions and the level of conviction that
insiders have about their own growth prospects.
But in periods of low earnings visibility, the supply of guidance
shrinks at precisely the time that the demand for guidance from investors
grows. During the financial crisis for
instance, many listed companies sought to manage their reputational risk by
ceasing to give guidance to the market.
Central
banks of course don’t have the luxury of ceasing communications to the market when
macroeconomic uncertainty increases. In
fact, they should (and most do) talk more during such periods. In his pioneering paper presented to the 2012
Jackson Hole symposium, Professor Michael Woodford argues that what central
bank speak reveals about the bank’s policy reaction function has greater market
impact than what the bank says about the economic outlook. After all, investors can form their own views
about the outlook based on alternative sources of information, notably the flow
of economic data.
Central bank
speak has taken on a new meaning for many central banks in recent years given
the unprecedented nature of quantitative easing. The volatile market reactions in recent
months to the Fed’s mixed messages on the likely timing of tapering illustrates
the perils of interpreting central bank speak.
The past week was no exception.
The
fundamental problem that the Fed faces is that animal spirits remain dormant in
the business and housing sector and this continues to weigh on the broader US
recovery. Despite the profit share of
GDP being at a record high, corporate gearing remains low, firms continue to
hoard cash, real business investment remains marginally below the peak from
five years ago and businesses remain reluctant to hire new workers; the hiring
rate of 3.2% remains close to historical lows.
Although the
flow of residential investment has grown by one-third since 2010, it remains
almost 50% below its 2006 peak.
Inflation expectations remain well anchored and various measures point
to still substantial slack in the labour market: the employment to population
ratio has barely recovered since the financial crisis, the unemployment rate
remains above 7% and the participation rate continues to decline to its lowest
level in over thirty years.
Given that
the Fed Funds rate hit the zero lower bound a number of years ago, the Fed has
used the two remaining levers available to it: quantitative easing and forward
guidance on the Fed Funds rate. In so
doing, the Fed is seeking to revive animal spirits through the wealth effect –
via higher asset prices – and by reducing the level of long term Treasury
yields and mortgage rates.
What is
crucial to the Fed’s task is using central bank speak to influence and manage
investors’ expectations. But this is
turning out to be more difficult than the Fed had probably envisaged. Woodford argues that the zero lower bound
does not render monetary policy impotent, but that effective forward interest
rate guidance can influence agents’ expectations of the term structure. If the central bank can convince economic
agents that it will keep interest rates close to zero for an extended period,
then it will be more effective in bringing forward agents’ decisions to spend
and invest, and in so doing, revive animal spirits.
The problem
that the Fed faces relates to its reputation, credibility and commitment; how
to credibly convince the market that it is going to commit to a certain course
of action in the future. Skeptikoi’s
interpretation of Woodford’s thesis on forward interest rate guidance is that
it is best achieved on a calendarised basis; the central bank commits to not
raising the operating interest rate for a fixed period, with a clause giving
the bank the flexibility to lengthen the amount of time if necessary (but not
shorten it). The market will be
sceptical of a central bank’s commitment to keep rates low for an extended
period if they believe that the bank will take away the punch bowl just as the
recovery is taking hold. Calendarised
forward guidance is credible precisely because it locks central bank into a
pre-determined course of action, thus denying the central bank the flexibility to
tighten policy during this period.
But Fed
speak suggests that it wants to have its cake and eat it too. Rather than use calendarised forward
guidance, it has adopted conditional forward guidance; the interest rate will
remain close to zero until (deliberately ambiguous) thresholds relating to
unemployment and inflation are hit. Data
dependent forward guidance allows the Fed to retain a fair degree of policy
discretion and flexibility to change its course of action. This represents an important trade-off for
the Fed to manage between policy flexibility and committing to a certain course
of action in the future. But the Fed’s
desire to retain policy flexibility undermines the efficacy of its forward
guidance. No wonder that markets are
confused and frustrated by Fed speak.
Interestingly,
the Fed’s decision to defer the tapering of its quantitative easing program demonstrates
the central bank’s willingness to sacrifice some policy flexibility for
credibility of a different kind. The
decision to defer speaks to the recent rise in uncertainty surrounding the
outlook and the Fed’s determination to manage its reputational risk. Rightly or wrongly, the Fed believes its
credibility as a forecaster would be undermined if it needs to re-initiate QE
after a decision to taper has been made.
But prior to its recent downgrade to its economic projections, its GDP
growth forecasts of 2.45% and 3.25% for 2013 and 2014 respectively, sat well
above consensus estimates.
Fed speak
suggests that the central bank appears to be more concerned about managing its reputation
as an economic forecaster than its credibility to committing to a future course
of action of keeping the Fed Funds rate low for an extended period. But Skeptikoi believes that the Fed’s credibility
on forward rate guidance is more important to sustaining the recovery than its
own track record as a forecaster. To
re-visit Woodford’s thesis, markets pay more attention to communications that reveal information about a central bank's policy reaction function than its views on
the outlook.
Skeptikoi can only
speculate that the Fed’s commitment phobia on forward rate guidance stems from an
aversion to inflation that has its antecedents in the spectre of the Great
Inflation of the 1970s, a time in which many of the senior members of the Federal Reserve were in the formative (and impressionable) years of their economics training. The Federal Reserve will
continue to be confounded by the market’s reaction to its communications and markets
will continue to be frustrated by a lack of clarity in Fed speak as long as the
Fed's commitment phobia on forward rate guidance persists.
