As finance ministers from the world’s twenty largest economies gathered in Buenos Aires on March 19, 2018, the cryptocurrency market was in freefall. Bitcoin had cratered below $7,500 over the weekend, Ethereum had shed 13% in a single day, and the total crypto market capitalization had plummeted from over $800 billion at the start of the year to roughly $283 billion. In the midst of this bloodbath, a quiet but consequential announcement from the Financial Stability Board (FSB) would set the tone for how regulators approached the emerging world of decentralized finance.
TL;DR
- The FSB told G20 members that crypto-assets “do not pose risks to global financial stability at this time”
- G20 finance ministers took a hands-off regulatory approach, setting a July 2018 deadline for specific recommendations
- Bitcoin had crashed from nearly $20,000 in December 2017 to around $8,600 by mid-March
- Argentina’s central bank governor called the closed-door crypto discussions “very productive”
- Italy’s central bank chief explicitly argued against banning cryptocurrencies
The FSB Letter That Calmed Markets
On March 18, one day before the G20 meetings officially began, the Financial Stability Board sent a letter to G20 members that would prove pivotal. The message was measured but clear: crypto-assets do not pose risks to global financial stability at this time.
For the nascent decentralized finance ecosystem, this was a significant statement. While traditional financial institutions had been sounding alarm bells about the rapid growth of crypto markets throughout late 2017 and early 2018, the FSB’s assessment suggested that regulators were taking a pragmatic, evidence-based approach rather than a reactionary one. The total cryptocurrency market, even at its January peak of over $800 billion, represented a fraction of the global financial system’s total value.
Bitcoin immediately responded to the FSB’s reassuring tone. After hitting a weekend low of approximately $7,335, the leading cryptocurrency began recovering on Monday, eventually pushing back above $8,600 by the time the CoinMarketCap snapshot was taken on March 19. The rally would continue into Tuesday, with Bitcoin briefly reclaiming $9,000 as G20 discussions unfolded.
Inside the G20 Crypto Discussions
The closed-door session on cryptocurrency at the G20 meeting in Buenos Aires devoted significant time to the topic, according to Argentina’s central bank governor Federico Sturzenegger. The tone was notably collaborative rather than punitive.
“The spirit of the discussion was very productive, and I agree that everybody left very pleased,” Sturzenegger told reporters during a press conference. “It was a very good meeting.”
Perhaps most notably for the DeFi community, Italy’s central bank governor Ignazio Visco went further than most of his peers. Visco told reporters that while cryptocurrencies do pose certain risks, they should not be completely banned. This sentiment would become a template for how many jurisdictions approached crypto regulation in the years that followed.
An anonymous poll conducted at the beginning of the meeting showed “very strong support” for including crypto-assets in multilateral discussions, particularly regarding their potential use as a “channel for the funding of terrorism for money laundering,” according to Sturzenegger.
What It Meant for Decentralized Finance
At the time of the G20 meeting, decentralized finance was still in its earliest stages. MakerDAO had launched its Dai stablecoin in December 2017, and the concept of “DeFi” as a distinct category was barely a year old. The total value locked in DeFi protocols would not be meaningfully tracked for another year.
However, the G20’s measured response had profound implications for the DeFi projects being built at the time. By choosing to monitor rather than restrict, regulators gave builders the breathing room to develop the protocols that would eventually grow into a multi-billion dollar ecosystem. The July 2018 deadline for specific recommendations meant that development could continue without the immediate threat of prohibitive regulation.
U.S. Treasury Secretary Steven Mnuchin summarized the American position at a Senate Banking Committee hearing in January, stating that bitcoin wallets should be “subject to the same regulations as a bank.” While compliance-focused, this framework was ultimately workable for DeFi protocols that would later integrate KYC and AML measures.
The Road Ahead
The G20 tasked several international bodies, including the Financial Action Task Force (FATF) and the Basel Committee, with developing recommendations by July 2018. Japan’s representatives pushed for stronger anti-money laundering cooperation among G20 members, while the European Commission advocated for bringing virtual exchanges and wallet providers under the Anti-Money Laundering Directive.
For decentralized finance, the Buenos Aires meeting represented a fork in the road that ultimately led toward regulation rather than prohibition, a path that, while sometimes cumbersome, allowed the ecosystem to grow, innovate, and eventually attract institutional capital.
Why This Matters
The March 2018 G20 meeting was the first time the world’s largest economies collectively addressed cryptocurrency regulation at the highest level. The decision to monitor rather than ban, informed by the FSB’s assessment that crypto did not pose systemic risk, gave the nascent DeFi sector the regulatory space it needed to develop. Every major DeFi protocol built after March 2018 did so in an environment shaped by the decisions made in Buenos Aires. Understanding this moment is essential for understanding why decentralized finance was able to evolve from an experimental concept into a significant financial sector.

fsb saying crypto no threat to stability at g20 was a relief
FSB said crypto was no threat when the entire market was $283B. they were right at the time and honestly still right now
FSB calling 283B no threat and then spending the next 5 years trying to regulate it anyway. make it make sense
BTC crashed from 20K to 8600 and the FSB still said crypto is no threat. they were technically right at 283B total market cap but imagine saying that with a straight face
g20_archive_ and now BTC alone is worth more than the entire 283B market cap they dismissed. the FSB letter aged like the ultimate buy signal
Arto V. the FSB letter is literally the best buy signal in crypto history. every time regulators dismiss it you should be loading bags
FSB said 283B was no threat and they were right at the time. now BTC alone is worth 10x that entire market
and that growth is exactly why the tune changed. same fsb now runs stablecoin and tokenization workstreams because at system scale even a small wobble is a macro event. size was always the variable
fsb said crypto was no threat in 2018 and honestly they were right. the entire market was 283 billion, a rounding error compared to tradfi
283 billion was the entire crypto market and they were sweating lol. compare that to where we are now
tobias_k nailed it. 283 billion total and tradfi was genuinely worried. now BTC alone is worth more than that
Italy arguing against banning crypto at G20 in 2018 was wild. every other central banker wanted prohibitions and they just said nah let people trade
italy at G20 in 2018 saying dont ban crypto while BTC was bleeding below 7500 and the whole market was 283B. argentina hosting and also calling the talks very productive was peak diplomatic nothingburger
italy_spoken_ every other central banker wanted bans and Italy just said let people trade. genuinely ahead of the curve
Italy central bank chief arguing against a ban in 2018 was surprisingly forward-thinking. most regulators were in full panic mode back then
Italy arguing against a ban in 2018 while the US was issuing subpoenas is a nice contrast. european regulators have generally been more reasonable on crypto
FSB saying crypto is no threat in 2018 while BTC was at $750 was the ultimate buy signal. regulators literally told you it was safe to accumulate
btc went from $20K to $8,600 and regulators still said chill. anyone who bought that dip is very happy now
Italy arguing against banning crypto in 2018 was surprisingly progressive. most central bankers were calling for outright prohibition back then
btc from 20k down to 8600 and total at 283b was brutal
reads wild now. the entire market cap was 283 billion, roughly a slow week of etf inflows today. fsb was right that it was small, they just never updated the take once it wasnt
a slow etf week matching the entire 2018 market cap is the stat that makes this article feel ancient. fsb called it right at the time, theyd get laughed out of the room saying it now
