Stablecoins like USD1 could reinforce the dollar, says Dave Lee

Key takeaways

  • Dave Lee, Founding Partner at Aqua Labs in Abu Dhabi, writes for BitcoinWorld that the core crypto question should not be whether digital assets can displace the US dollar.
  • He argues blockchain infrastructure can make dollar-denominated money more efficient and accessible, potentially embedding the dollar deeper in global finance.
  • USD1, a stablecoin redeemable one-to-one for US dollars and backed by dollar-denominated reserve assets, is used as the example of a dollar existing directly on a blockchain.
  • Recent foreign exchange market stress, including Japan's heavy intervention to support the yen against the dollar with US participation, reinforced the dollar's role as the primary reference point for global capital.
  • Lee links stablecoin adoption to tokenization of funds, securities, commodities and other real-world assets, and to the US government's growing regulatory framework.

What happened

The article published by BitcoinWorld revisits a debate that has followed Bitcoin since its launch in 2009: whether digital assets threaten the dominance of the world's most important currency. Lee says that framing is misleading. Because blockchain technology is now a persistent part of financial infrastructure, the more useful question, in his view, is whether it can improve the efficiency and accessibility of the US dollar rather than replace it.

The piece centers on USD1, which is redeemable one-to-one for US dollars and backed by dollar-denominated reserve assets. Unlike a dollar balance held in a traditional bank account, USD1 exists directly on the blockchain. The distinction is not that the economic value changes; the dollar remains the unit of account. The change is in the transfer mechanism. A conventional dollar payment may pass through banks, payment processors and settlement systems, while a digital dollar can move between wallets on a blockchain without relying on the same chain of intermediaries that many cross-border payments require.

Market context

Lee grounds the argument in an episode from the foreign exchange market over the summer. Japan intervened heavily to support the yen as it came under significant pressure against the dollar, and the US also participated in the market operation. Whatever one's view of the intervention, the episode highlighted a long-standing feature of the international financial system: during stress, capital still looks first to the dollar as the main reference point.

That reference point is now being expressed through a new layer of infrastructure. Stablecoins are bringing dollar-denominated value onto blockchain networks. In traditional cross-border transactions, the friction is not only technical. It can involve reconciliation layers, multiple intermediaries, different jurisdictions, settlement systems, operating hours and exposure to geopolitical disruptions. Even minor changes in conditions can impede movement of money. A blockchain-based dollar transaction is less exposed to many of these constraints because it does not require the same settlement chain.

Why it matters

For Lee, the next phase of financial innovation is not necessarily about inventing new forms of money. It is about rebuilding the infrastructure through which existing money moves. USD1 is presented as an example of that shift: the value stays a dollar, but the rails are digital.

This matters because the dollar already holds advantages that new digital money would struggle to replace: liquidity, institutional trust, deep capital markets, global acceptance and a long legacy. Stablecoins do not need to discard those advantages. Instead, they can make them available through a more efficient technological architecture.

A digital dollar can also be integrated directly into financial software. It can be used as collateral, embedded into digital capital markets and transferred automatically when predefined conditions are met. A distributed network can reduce dependence on multiple intermediaries, which becomes increasingly relevant as tokenization develops. Financial assets are moving onto blockchain infrastructure, from funds and securities to commodities and other real-world assets. If those assets are traded or settled digitally, the money used against them will increasingly need to exist digitally too.

The article also connects this to regulation. Lee sees the US government's growing regulatory framework for stablecoins as significant because it can treat stablecoins not solely as a threat to the monetary system, but as a potential way to extend dollar liquidity and create additional demand for US Treasury assets. As stablecoin utility grows, more institutions may participate in blockchain-based financial infrastructure, which could reinforce the dollar's role within the digital economy.

Lee says the dollar's importance within the traditional financial system is not up for debate, despite some voices to the contrary, and stablecoins point to its increased importance.

What to watch

The central argument is that blockchain may add a new layer to the financial system with the dollar at its center, rather than eroding it. Lee expects the conversation to move beyond de-dollarization toward digital dollarization.

The practical test is whether dollar-denominated stablecoins and tokenized financial infrastructure can operate within the developing US regulatory framework while attracting broader institutional use. If the US leads innovation in stablecoins, tokenization and blockchain-based financial markets, Lee suggests one of the main beneficiaries could be the dollar itself. That is a structural claim about money's infrastructure, not a price forecast.
