High inflation has its origins in the response to the COVID-19 pandemic, when governments restricted social contact through lockdowns. This was accompanied by huge fiscal and monetary stimulus to support the economy, leading to a surge in money supply.

With the public receiving stimulus money but forced to stay home, consumption was channeled away from services, such as food and beverage, entertainment and travel, and to the goods sector.

This phenomenon occurred at a time when the pandemic significantly disrupted global supply chains. Excess demand for goods at a time of restricted supply inevitably drove up prices.
Stimulus money and record low mortgage rates also led to a housing boom with residential prices in the U.S. rising by up to 50% in some markets since the beginning of 2019.
Other factors underpinning inflation include a spike in oil prices resulting from major producers keeping production low despite a strong rebound in demand after economies re-opened.

Russia’s invasion of Ukraine added further impetus to inflation. Supply constraints and sanctions pushed up natural gas prices in Europe, exacerbating the demand/supply imbalance in the global economy. Both countries are also major commodities producers, so the supply and cost of raw materials such as wheat has also been impacted.

These factors have created an environment in which highly stimulated demand has converged with highly disrupted and restricted supply, driving up inflation.
