From a January lockdown in a Chinese province to 10 million infections worldwide, the coronavirus' march across the globe has buffeted markets at every step these past six months, roiling the very plumbing of the global financial system.

Market panic and economic devastation from lockdowns elicited an unprecedented response from policymakers, sowing seeds of recovery.

The following charts aim to capture some of the milestones.

On Jan. 21, there were reports of a "flu-like" virus in China and soon after the city of Wuhan closed urban transport and suspended outgoing flights.

By Jan. 27, the World Health Organisation declared an emergency in China, hitting the yuan and Chinese equities.

4) EUROPEAN U-TURNS

The crisis forced a U-turn on budget frugality, notably in Germany which on March 23 announced a spending package of up to 750 billion euros. Britain also reversed "austerity", with 133 billion pounds in pledges.
