Crypto Is Failing Where Digital Yuan May Succeed

Does an industrial-sized dog whistle go off when advocates boast about cryptocurrencies ability to evade US government sanctions?

Back in March, a founder of Tornado Cash a so-called mixer service that masks cryptocurrency transactions by mixing them with others told Bloomberg it would be technically impossible for sanctions to be enforced against decentralized protocols. Surprise: Tornado has now been sanctioned by the US Treasurys Office of Foreign Assets Control, partly because of its use by hackers said to be linked to North Korean money laundering.

With Tornadodown 95% from its all-time highand its source code removed from Microsoft Corp.s GitHub, itsthe latest blow to theno sanctions yay theory of crypto the three wordsused by former Ethereum Foundation scientist Virgil Griffith in 2019 when he told a blockchain conference in North Korea how to dodge sanctions by converting cash into crypto, costly advice that resulted in a guilty plea and a 63-month federal prison sentence.

In terms of technology, it shows that even the most decentralized service cant avoid law enforcement.Exchanges are under pressure to monitor links toregular currencies, as are other service providers, andpseudonymous blockchains can be pored over for suspicious transactions such as the gains of North Korean cyber criminals that transited through Tornado. As Bloombergs Emily Nicollenotes, the crypto industry hasnt been able to build all its infrastructure yet.

Geopolitically, crypto is also suffering not surging amidaneconomic Cold War. After the Covid-19 pandemic and Russias invasion of Ukraine, Washingtonhas been flexing its financial muscles, even amidangst about the kind of blowback thatoverreach or alternative currenciesmight bring. Keeping crypto in check fits with the history of US regulation of encrypted tech, like thee-mail mixers of the 1990s, but is also key for USsoft power in wartime.

Ironically, even opponents of a dollar-based global economy have been ambivalent at best about crypto. For the likes of Russia and Iran, global pariahs that are also big energy exporters, cryptosthreats undermine its potential.While in theory they might be able to use crypto to facilitate trade and bypass US monitoring, thats outweighed by theprospect ofcapital flight, instability and price volatility. Moscow has veered between banning and encouraging digital assets, doubtless recognizing that they can help sanctioned elites on some level. But the ruble still carries muscle as recent arm-wrestling with the European Union over gas payments demonstrated.

While Tehran this weekannounced its first official import order using an unnamed cryptocurrency, according to Reuters, this is only one in a long line of crypto tests that have failed to gaintraction. Regulation has also been erratic, as Iranian cryptominers have recently found.

Right now, therefore, it looks like even a world permeated by unprecedented sanctions, conflict and inflation will fail to give crypto a big boost. And as economist Eswar Prasad recently wrote, USdollar hegemony could last a lot longer than expected.

But theres one potential twist in the tale: central bank digital currencies, notably Chinas e-yuan. These forms of digital money might play a big geopolitical role depending on how theyre implemented and who gets there first.

A new book by sanctions experts Astrid Viaud and Paul-Arthur Luzu imagines a world in which China gains a first-mover advantage with a digital currency that is interoperable with others and imposes standards on other countries looking to avoid doing business in dollars.

Onescenario wargamed by US officials, according to CoinDesk, is of a fully portable digital yuan that sees other countries using banks and payment providers as nodes effectively plugged into Chinas infrastructure. That might see North Korea or Russia buy materials without reprisals. Iran is pursuing a digital central bank currency of its own.

This is only one future among many it may be that US and euro area digital currencies take off first, or that such projectsend up fragmenting existing systems rather than strengthening them. And either way, its all far-off.

But it suggests that the payments cold war has a long way to go before threats to the US dollar manifest themselves. It opens up a new zone of conflict that ensures no sanctions yay will remainlittle more than a slogan.
