Several banks have been affected by global outages, including Bank of America, Capitol One, and Charles Schwab. These outages have disrupted payment services and grounded flights worldwide. While the cause of the outages is not entirely clear, they appear to be related to a broader technology outage affecting multiple organizations.
Bank of America customers have reported issues with online banking, mobile check deposits, and funds transfers. Some have received error messages when attempting to access their accounts online, while others have had transactions declined at ATMs. These issues have resulted in lengthy hold times for customer service and significant inconvenience for those impacted.
Capitol One users have also experienced difficulties with online login, deposits, and credit cards. While Capitol One acknowledged isolated issues with its app, it directed customers to use its mobile web or desktop site as alternatives.
Similarly, Charles Schwab customers have faced disruptions, particularly with its Think or Swim Web platform. However, some users noted that the mobile app was functional, allowing them to place trades and access other services.
The global outage has impacted multiple banks and their customers, causing frustration and highlighting the reliance on stable technology infrastructure in the financial sector.

The global outage was caused by a software update at cybersecurity firm CrowdStrike
On 19 July 2024, a global technology outage caused by a software update at cybersecurity firm CrowdStrike affected computers running Microsoft Windows. The update contained a defect that caused problems for companies that use Microsoft Windows, with issues starting as early as midnight Eastern Time on Thursday. By early Friday morning, Microsoft had reports of successful recovery, and repairs had begun. However, the outage had already impacted various industries and services worldwide, including banks and financial institutions.
CrowdStrike provides software to thousands of companies worldwide, and its Falcon platform helps protect systems against potential threats to minimize cybersecurity risks. The company has stated that the issue was not a security incident or cyberattack and that a fix has been deployed. Despite this, the outage disrupted daily life, businesses, and governments around the world, with widespread problems across multiple countries and time zones.
In the financial sector, banks reported issues with online banking, mobile banking, deposits, funds transfers, and account access. While some banks, such as TD Bank, confirmed that their impacted systems had been restored, others, like Charles Schwab, reported intermittent slowness or unavailability of certain online functions. Users of several banks reported outages, with issues including online banking, mobile check deposits, funds transfers, and credit cards.
The global outage highlighted the fragile dependence of the global economy, especially in the aviation industry, which experienced significant disruptions and backlogs. The London Stock Exchange also saw operations grinding to a halt, and media companies and broadcasters reported issues going on air. The widespread impact of the outage has been estimated to result in a worldwide financial loss of at least US$10 billion.
The CrowdStrike outage raised questions about the centralization and oligopoly in the IT sector, with cybersecurity expert Ciaran Martin noting that the incident illustrated the fragility of the world's core internet infrastructure. The company faced lawsuits and compensation claims from affected organizations, and it testified in a U.S. House of Representatives hearing held by the House Subcommittee on Cybersecurity and Infrastructure Protection.
