MACRO AND MARKET PERSPECTIVES

Fed to raise its inflation game?

The Federal Reserve is considering new options to steer inflation expectations. We consider the economic and market implications.

The Fed's challenges

The Federal Reserve could announce significant changes to its monetary policy approach early next year.

US and eurozone market-based inflation expectations, 2010-2019

Sources: BlackRock Investment Institute, with data from Bloomberg, May 2019. Notes: The chart shows the market pricing of inflation based on five-year forward inflation in five years' time. The Fed target is adjusted 25 basis points higher to account for the difference in market pricing of the CPI index in inflation swaps relative to the PCE inflation index, the Fed's target. The ECB targets inflation just below a 2% reference point.

An in-depth review is in full swing. The policy review aims to address the challenges faced by central banks in the aftermath of the global financial crisis. These challenges are rooted in falling neutral interest rates – rates that would neither stimulate nor hold back economic growth – and declining inflation expectations. Both of these could limit the ability of monetary policy to counter future downturns.

These two factors reduce the distance between the actual interest rate and the effective lower bound (ELB) – the minimum level of interest rates that the central bank can feasibly set. The negative policy rates in Japan and the eurozone, for example, show that this level can be below zero. Interest rates below zero could harm the profit model of the banking sector and even lead to depositors – who may have to pay the bank to hold their money – withdrawing their money from the system.

We assess the implications of any shift from the flexible inflation forecast targeting that the Fed and other developed market central banks currently follow towards strategies that explicitly require central banks to make up for past misses of their inflation target –“make-up” strategies. These options are being discussed by the Fed, and other central banks – the Band of Canada and Sweden’s Riksbank – have pondered similar changes in the past. The European Central Bank (ECB) may also re-assess its strategy after a leadership transition later this year.

The debate in central bank circles – with the Fed leading the way – reflects two factors that could potentially limit the effectiveness of monetary policy in any future downturn. First, a decline in the neutral rate of interest implies that average policy rates are gravitating lower. Second, after an extended period where inflation has been below central bank targets, inflation expectations are becoming untethered and shifting below inflation targets on a sustained basis. See the Lying low chart above.

Projections by the Fed (Roberts and Kiley 2017) suggest that the ELB could become a constraint for US monetary policy for around one third of the time – a risk that had been very small prior to the Great Recession. Once the ELB is reached, the Fed cannot reduce interest rates any further in a recession. This means unconventional policies –such as quantitative easing (QE) – would again become the second-best instruments of choice. Then, the inability to cut rates further could lower inflation expectations again, potentially shrinking monetary manoeuvring room even more. There is an obvious desire to avoid the deflation spiral and liquidity trap problems seen in the Great Depression – or in Japan.
