Bitcoin poses no threat to financial stability and is unlikely to rattle mainstream markets in the next couple of years, a group of leading European economists have said.

According to a survey of almost 50 academics from universities across Europe by the Centre for Macroeconomics and the Centre for Economic Policy Research, the majority are sanguine about the risks posed by the digital currency despite repeated warnings by senior financiers.

Bitcoin’s small size and detachment from the wider financial system was one of the key reasons for comfort among the economists, who said major investment groups did not hold significant amounts of the digital currency. While bitcoin has surged in value by more than 900% this year, its total value stands at about $300bn, paling in comparison to the total value of global shares at almost $80tn.

Senior financiers including the chief executives of JP Morgan and Goldman Sachs have warned against bitcoin in recent months, while the chairman of the Royal Bank of Scotland likened it to Dante’s Inferno, saying it was a speculative bubble in need of an apocalyptic health warning for investors from central banks.

There have been fears over the ability for banks to cover losses on bitcoin trading, with a group of major investment banks writing a letter to US regulators to say that the system of regulation was ill-prepared.



The cryptocurrency has become increasingly part of the wider financial system, after making its debut on the world’s largest futures exchange on Sunday evening, when the Chicago Mercantile Exchange (CME) became the second exchange to offer bitcoin derivatives trading.



The January 2018 contract traded on the CME initially spiked above $20,000 but later dropped, having been originally priced at $19,500.

A note of caution was sounded by Wouter den Haan of the London School of Economics, who responded to the survey by saying that past crises showed it could “take just one key financial institution taking on large risky positions to put the system at risk”.

Although the majority of economists believed there were limited risks to financial stability, they also said governments should introduce greater controls for cryptocurrencies as their anonymity and opacity could help enable tax evasion and other criminal activities.

Nicholas Oulton of the London School of Economics said: “One strand of current policy is to crack down on money laundering and tax evasion through tax havens. So it would seem odd to let cryptocurrencies get around these restrictions.”

The findings come after a South Korean cryptocurrency exchange appears set to file for bankruptcy after it was hacked for the second time this year, highlighting concerns about security amid booming trade in bitcoin and other virtual currencies.



The exchange, called Youbit, had been hacked once before in April when nearly 4,000 bitcoins were stolen in a cyber-attack that the country’s spy agency linked to North Korea, according to a recent South Korean newspaper report.

Youbit announced on its website on Tuesday that it had been hacked at 4.35am local time, causing a loss worth 17% of its total assets.

It did not elaborate on the amount, but said all customers’ cryptocurrency assets would be marked down to 75% of their value. It added that it had stopped trading and would work to minimise customer losses.

Q&A What is bitcoin? Show Bitcoin is the first, and the biggest, 'cryptocurrency' – a decentralised tradeable digital asset. The lack of any central authority oversight is one of the attraction. Cryptocurrencies can be used to send transactions between two parties via the use of private and public keys. These transfers can be done with minimal processing cost, allowing users to avoid the fees charged by traditional financial institutions - as well as the oversight and regulation that entails. This means it has attracted a range of backers, from libertarian monetarists who enjoy the idea of a currency with no inflation and no central bank, to drug dealers who like the fact that it is hard (but not impossible) to trace a bitcoin transaction back to a physical person. The exchange rate has been volatile, making it a risky investment. Whether it is a bad investment is yet to be seen. In practice it has been far more important for the dark economy than it has for most legitimate uses, but with Facebook's announcement that it is launching a new digital currency - Libra - mainstream interest in bitcoin has surged.



It is the second hacking in a fortnight. Nearly $64m of bitcoin was stolen by hackers who broke into the Slovenian-based bitcoin mining marketplace NiceHash.

Bitcoin exchanges and wallets have a history of being targeted, and security experts say they become more vulnerable to cybercrime as valuations rise.
