Global Inflation's Grip: The Economic Timeline from Stimulus to Rate Hikes

Remember March 2020? Governments worldwide unleashed an estimated $16 trillion in fiscal stimulus and central banks flooded markets with liquidity, slashing interest rates to near zero. It was an unprecedented response to an unprecedented crisis, but it also laid the groundwork for the economic rollercoaster we've ridden ever since.

The Federal Reserve's balance sheet ballooned by $4.7 trillion between February 2020 and March 2022, while the European Central Bank launched its €1.85 trillion Pandemic Emergency Purchase Programme. This massive injection of cash, combined with direct aid like stimulus checks, kept economies afloat.

Suddenly, a surge in demand for goods—fueled by consumers stuck at home with extra cash—collided with a constrained ability to produce and deliver them. "We injected so much money into the system, it was like trying to fill a bathtub with a firehose while the drain was partially blocked."

Inflation's Unstoppable Rise: From Transitory to Persistent

By late 2021, the signs were clear: inflation wasn't just a temporary blip. The US Consumer Price Index (CPI), for example, hit 7.0% in December 2021, a level not seen in nearly 40 years. This was exacerbated by soaring energy prices, particularly after Russia's invasion of Ukraine in February 2022, which sent oil and natural gas costs through the roof. Food prices followed suit, hitting vulnerable populations hardest.
