🦠 Pandemic & health crisis
A pandemic is a crisis of movement: people stop travelling, commuting, gathering and — for a while — spending. The 2020 experience gave markets their first full-scale, data-rich pandemic playbook, and it was extreme in both directions.
What history shows
COVID-19 (2020) produced the fastest bear market in history: the S&P 500 fell 34% in just 23 trading days in February–March 2020. The distortions were unprecedented — in April 2020 the front-month US oil futures contract briefly traded at negative $37 a barrel, because the world had nowhere left to store unwanted crude. Airlines lost more than half their value; cruise lines far more.
Then came the second half of the playbook. Massive monetary and fiscal support, plus a forced shift of life online, powered the "stay-at-home trade": technology and e-commerce stocks led one of the strongest recoveries ever recorded, vaccine developers became household names, and consumer staples and home improvement boomed. Government bonds rallied as central banks cut rates to zero. The office, meanwhile, never fully refilled — commercial property, especially offices and retail, carried the longest-lasting scar of the crisis.
Earlier episodes — SARS (2003), the 1918 influenza — were either regionally contained or predate modern markets, but they rhyme: travel and gathering industries suffer first and worst, healthcare demand surges, and the economic damage depends more on the policy response than the pathogen itself.
Assets that have tended to gain
- Healthcare & pharmaceuticals — vaccines, treatments, diagnostics: demand is immediate and government-funded — billions of doses were pre-ordered in 2020.
- Technology & digital services — work, shopping, entertainment and payments all move online at once.
- Consumer staples — pantry-loading is real; supermarkets ran record volumes in 2020.
- Government bonds and cash — the classic flight to safety, amplified by emergency rate cuts.
- Gold — reached a then-record high above $2,000/oz in August 2020 as real interest rates collapsed.
Assets that have tended to suffer
- Airlines, travel & tourism — global passenger traffic fell by roughly 60% in 2020; recovery took years.
- Commercial property — remote work permanently reduced office demand in many cities.
- Oil and energy — transport is the biggest single use of oil; lockdowns crushed it.
- Banks — rate cuts squeeze margins while loan-loss provisions jump.
Wildcards and caveats
The 2020 rebound was turbocharged by the largest stimulus in peacetime history — a policy choice, not a law of nature. A future pandemic met with less support (or arriving alongside high inflation, which limits central banks' room to cut) could follow the crash half of the playbook without the recovery half. Position for the mechanism, not the memory.
