Paragraph 3 Globalisation has suffered a severe setback as a result of the COVID-19 pandemic. Cross-border capital flows never fully recovered from the global financial crisis. This latest shock first hit the international movement of people, but the global economic downtum will inevitably reduce cross-border trade and investment. The pandemic hit a world economy that was already struggling with the consequences of a destructive trade war. Global supply chains have been disrupted by shut-downs in the production of key components These supply chains are highly optimised to business-as-usual conditions and are designed to keep inventories to a minimum to reduce costs. Intemational trade normally reduces vulnerabilities to localised shocks, but the global nature of the pandemic makes supply chain disruptionsinevitable. If anything these disruptions dramatize the hidden benefits rather than the costs of globalisation The availability of the goods and services that we previously took for granted now seems less secure.Part 2[15 marks] Use search engine and paragraph Three (3) as reference to analyse impacts of Covid- 19 across borders and to Australian economy.
