How Inflation Went From Dormant To Dominant

“How did you go bankrupt?”

“Two ways: gradually, then suddenly.”

-- Ernest Hemingway, The Sun Also Rises

Variations of this quote have been used to describe a wide range of descents that begin slowly before reaching a tipping point. Examples include the declines of empires, pandemics and (prospectively) climate change.

Today, the citation from Hemingway describes concern about inflation over the past year. At first, the risk was minimized; now, it is almost all we can talk about. Most policy makers were slow to react; more recently, they have been picking up the pace.

How could something that now seems so obvious have eluded the expectations of so many? A trip back in time reveals that what is painfully apparent today was not easy to anticipate, and that central banks weren’t the only ones who underestimated the evolving threat.

Along those same lines, the current rush to revise expectations may ultimately be viewed as a miscalculation. A review of recent history and a tour through the major drivers of inflation may provide lessons for what lies ahead.
