The recent global tech outage that disrupted Australian banks, supermarkets, airports, and various businesses has drawn significant attention from economists. Triggered by an error in a software upgrade by US cybersecurity company Crowdstrike, the outage left many businesses inoperable for hours, with economists now assessing the financial toll.
The outage’s immediate impact was felt across several sectors. Retailers and supermarkets faced closures or limited operations, as critical services like EFTPOS, online orders, and self-serve checkouts were unavailable. Businesses had to revert to manual processes like paper receipts, significantly slowing down transaction speeds. This highlights the modern economy’s dependency on IT infrastructure, where disruptions can halt economic activity. Despite this short-term disruption, economists are not concerned about the long term impacts as consumer activities were merely delayed, not eliminated.
Financial markets were also impacted by the outage. As it occurred near the close of the Australian Securities Exchange, local market impacts were limited. However, CrowdStrike’s shares dropped by 11.1%, while competitors Palo Alto Networks and SentinelOne saw gains. Broader market reactions in the US were influenced by multiple factors, including a rotation away from tech stocks and political uncertainties.
Therefore, the recent IT outage underscores the critical role of IT systems in maintaining economic stability. This incident highlights the importance of resilient IT infrastructure and the need for strategic planning to prevent similar occurrences. As businesses and governments analyse the fallout, the focus will likely shift towards enhancing cybersecurity measures and ensuring robust backup systems to safeguard against future outages.
