The inflation saga: addressing the elephant in the room

A little inflation is always considered healthy. Why? For two key reasons:

(1) it is expected to amplify consumption as the purchasing power of future cash flow reduces and

(2) it prompts increased investment, enlarging the overall economic pie.

But how much inflation is good inflation? This is a topic that has gained attention recently, especially as global pricing prints have increased since the start of the pandemic. The bigger question is whether the real inflation rate is sitting on a permanently higher trajectory. The answer is critical to determining an expected economic growth trajectory for the US, as it would feed into mortgage costs, stock market volatility, consumption sentiment and overall growth potential.

The Fed has a loosely defined flexible average inflation-targeting framework that aims for a 2% target rate [stated usually in terms of personal consumption expenditure (PCE)] over the long run but is accommodative during periods of volatility and disruption, especially when price increases are assumed to be largely transient. This is interesting because PCE has historically trended lower than consumer price inflation (CPI), which may give some credibility to the Fed’s 2% framework as not being conservative (see figure below).

PCE is generally seen as a better measure because the spending composition better depicts actual consumer behaviour. However, more attention is paid to CPI because it is used to adjust social security payments and is also the reference rate for certain financial contracts, such as Treasury Inflation Protected Securities (TIPS) (TASE:KSMF179) and inflation swaps. Whether we measure CPI or PCE, it is evident that current inflation prints are running as high as they were in 2008 and the 1990s
