Market round-up: Bloomberg blackout hits trading as FTSE 100 drops below 7,000
The FTSE 100 slumped by almost 1% after a worldwide Bloomberg blackout was thought to have affected trading volumes.
The index of leading shares closed Friday at 6,994.63, down 65.82 points (-0.93%).
Bloomberg's trading and information terminals are used by approximately 320,000 people around the world and the two-hour outage is likely to have affected trading volumes.
The glitch meant the UK's Debt Management Office had to postpone an auction of short-term Treasury bills that was expected to raise £3bn ($4.48, €4.16bn).
"The modern way of getting a trade done is through Bloomberg chat, so without it, traders were a bit at a loss. Of course there is always a telephone if the deal is urgent," explained CMC Markets analyst Michael Hewson.
Bloomberg said in a statement: "Service has been fully restored. We experienced a combination of hardware and software failures in the network, which caused an excessive volume of network traffic.
"This led to customer disconnections as a result of the machines being overwhelmed. We discovered the root cause quickly, isolated the faulty hardware, and restarted the software.
"We are reviewing our multiple redundant systems, which failed to prevent this disruption."
