Microsoft Outage Forces Japanese Markets To Dust Off Fax Machines

The ongoing Microsoft outage forced major firms to bypass crippled email authentication systems using phones, WhatsApp, and faxes. It also disrupted retail FX email logins, exposing the capital markets' dangerous reliance on SaaS monopolies.

The disruption peaked with over 130,000 Downdetector reports in the US before rolling into Asia-Pacific business hours, heavily impacting Microsoft's Exchange Online service. Microsoft acknowledged the issue, stating they were investigating reports of users experiencing problems accessing Exchange Online mailboxes through multiple connection methods in the Americas.

FX Brokers Hit by Communication Blackout

For retail brokers, the operational impact was immediate. Japanese broker SBI FX Trade alerted clients that Outlook users were unlikely to receive vital login and execution emails, advising them to monitor trading tools directly. Golden Way (GW) Securities, operator of FXTF, reported that while login codes functioned, email inquiries were entirely down.

According to Bloomberg, brokerages across Singapore and India warned of massive delays in customer support, while the failure of Outlook and Teams triggered an immediate shift to manual fallback operations. At CMC Markets in Singapore, traders relied on phone calls and WhatsApp to manually bypass automated online systems.

Hand-offs and the Return of the Fax

But nowhere was the technological regression more glaring, or darkly comedic, than in Tokyo. As back-office trade confirmations bottlenecked, Bloomberg reported that desks at firms like BNP Paribas Asset Management had to process settlements manually, while portfolio managers at hedge funds like Blue Edge Advisors said the outage crippled the front-to-back infrastructure of global finance, blocking access to research and trading platforms that relied on email authentication.
