(Bloomberg) -- For central banks contemplating issuing a digital currency, there could be advantages to getting it done soon, according to a European Central Bank study.

A country without a digital currency would lose some control over its monetary policy by being forced to react more strongly to spillovers from shocks in nations that do have such an instrument, researchers Massimo Minesso Ferrari, Arnaud Mehl, and Livio Stracca found.

They predict that such international spillovers would be ampified “to a significant extent” in open economies because the cash-like and asset-like qualities of digital currencies would be attractive to investors.

“Introducing a central bank digital currency sooner rather than later could give rise to a significant first-mover advantage to its issuer,” the authors wrote.

The study could have significant implications for central banks worldwide as they explore how and if to launch digital versions of their currencies.

The People’s Bank of China has already made significant headway in pilot tests with consumers.

ECB President Christine Lagarde said last week that while her institution is “not racing to be first,” her “hunch” is that it could create a digital currency within years.

She returned to the topic on Thursday, telling the European Parliament that the pandemic on the continent -- parts of which have been slow to adopt digital payments -- has accelerated a shift in public attitudes.
