May 16, 2018, was a landmark day for cryptocurrency infrastructure development, even as market prices tumbled. Circle, the Goldman Sachs-backed fintech company, announced it had raised $110 million to develop a new U.S. dollar-pegged stablecoin that would eventually become one of the most important assets in the entire crypto ecosystem. Meanwhile, Coinbase rolled out a suite of institutional-grade products aimed at bringing professional traders into the digital asset market.
TL;DR
- Circle raised $110 million to build USDC, a dollar-pegged stablecoin designed to address transparency issues in existing stablecoins
- Coinbase launched institutional products including custody services, a centralized liquidity pool, and advanced trading tools
- South Korea’s UPBit exchange was cleared by an independent audit after fraud accusations
- Japan’s Mitsubishi UFJ, the world’s fifth-largest bank, announced plans for its own MUFG coin pegged to the yen
- The announcements came during a brutal market downturn with Bitcoin at ~$8,368 and Ethereum at ~$707
Circle’s Bold Bet on a Better Stablecoin
Circle’s announcement of a $110 million funding round was significant not just for the amount raised, but for what the capital was intended to build. The company laid out plans to create a fiat-backed cryptocurrency pegged to the U.S. dollar — what would eventually be launched as USD Coin (USDC). The token was designed to compete directly with Tether (USDT), which at the time dominated the stablecoin market with a circulating supply of approximately $2.3 billion.
Circle was direct in its criticism of existing stablecoin solutions. The company stated that “existing fiat-backed approaches have lacked financial and operational transparency,” a pointed reference to the growing concerns about Tether’s banking relationships and audit controversies. By promising full dollar reserves and regular attestations, Circle positioned USDC as the transparent alternative that institutional players had been waiting for.
The funding round drew investment from major players including Bitmain, the Chinese mining hardware giant, and represented one of the largest single investments in a crypto infrastructure project at the time. The bet would prove prescient — USDC would go on to become the second-largest stablecoin in the world, with tens of billions in circulation.
Coinbase Goes After Wall Street
On the same day, Coinbase made its most aggressive push yet into the institutional market. The San Francisco-based exchange announced a comprehensive suite of products designed to address the specific needs of professional traders and large investors who had been sitting on the crypto sidelines.
The centerpiece was Coinbase Custody, a dedicated digital asset custody solution built in partnership with Electronic Transaction Clearing (ETC), a SEC-qualified custodian. For institutions managing billions in assets, the lack of qualified custody had been one of the biggest barriers to crypto investment. Coinbase also introduced a centralized liquidity pool designed to minimize market impact for large trades, prime brokerage services, and more sophisticated trading software tools.
The timing was notable. While retail traders were fleeing the market amid plunging prices — Bitcoin had fallen more than 60% from its December 2017 highs — Coinbase was building the infrastructure for the next wave of institutional adoption. It was a classic case of building during the bear market for the next bull run.
UPBit Cleared in South Korea
In South Korea, there was encouraging news for the embattled crypto industry. UPBit, the country’s largest cryptocurrency exchange, was cleared by a major accounting firm following an audit triggered by accusations of fraud. The exchange had been accused of deceiving investors by inflating its balance sheet, but the audit confirmed no foul play had occurred.
The initial concern stemmed from the fact that UPBit did not manage individual wallets for 30 of the 120 cryptocurrencies it offered for trading. Holders of those 30 tokens had to convert to other cryptocurrencies before they could withdraw. The audit found this was an operational choice, not an indication of missing funds or deception.
Mitsubishi UFJ Plots Its Own Cryptocurrency
Perhaps the most forward-looking announcement of the day came from Japan. Mitsubishi UFJ Financial Group (MUFG), the world’s fifth-largest bank by assets, revealed plans to create its own digital currency. The proposed MUFG coin would be pegged to the Japanese yen at a 1:1 ratio and was expected to become available to approximately 100,000 MUFG account holders starting in 2019.
If realized, the MUFG coin would have been by far the largest implementation of a fiat-backed cryptocurrency by a traditional financial institution. The announcement signaled that major banks were beginning to take blockchain-based digital currencies seriously — not as speculative assets, but as practical tools for payments and transfers.
Why This Matters
May 16, 2018, perfectly illustrates the disconnect between crypto market prices and the underlying infrastructure development. While traders panicked over plunging altcoin prices and Bitcoin’s continued decline, the industry’s most important companies were laying the groundwork for the next phase of growth. Circle’s USDC would go on to become a cornerstone of decentralized finance, Coinbase’s institutional products would eventually attract billions in professional capital, and the MUFG experiment previewed the central bank digital currency conversations that would dominate financial policy discussions for years to come. The lesson is clear: the most important crypto developments often happen when the market is at its bleakest.
