An a16z crypto analysis explains how global financial plumbing is being rebuilt onchain by visionary founders rather than legacy institutions. This shift promises efficiency, transparency, and accessibility for capital markets.

What happened

According to a recent analysis by a16z crypto, the global financial "plumbing" is undergoing a radical transformation. While major exchanges and legacy banks have dominated the system for decades, the next generation of financial infrastructure is not being built by these incumbents. Instead, startup founders are leveraging blockchain technology to rebuild core processes—from settlement to trading—directly onchain. This shift aims to eliminate inefficient intermediaries and drastically reduce operational overhead.

Technology context

Being "onchain" means executing and recording transactions directly on a distributed ledger (blockchain), rather than relying on private databases or manual reconciliation. In the traditional system, a single trade passes through multiple entities (brokers, correspondent banks, clearinghouses), each maintaining its own ledger. Blockchain technology provides a "single source of truth" where assets are represented as tokens and trading rules are enforced by smart contracts. This enables the programmability of money and financial assets.

Why it matters

The impact of this transition is monumental for capital efficiency. Currently, settling a trade in capital markets can take days (T+2). On a blockchain, settlement is near-instantaneous (T+0). For both users and institutions, this means eliminating counterparty risk and freeing up massive amounts of capital currently locked in waiting periods. Furthermore, onchain infrastructure operates 24/7, unlike traditional markets that operate on fixed schedules and close during weekends.

Key terms explained

Impact

In the short term, we will see a surge in projects focused on the tokenization of Real World Assets (RWA), such as Treasury bills or money market funds. In the medium term, the barriers between Traditional Finance (TradFi) and Decentralized Finance (DeFi) will blur. Institutions that refuse to adopt these standards risk obsolescence, while new players will be able to offer complex financial services at a fraction of current costs, democratizing access to sophisticated investment tools.

What's next

Predictions point toward a massive migration of credit markets and derivatives to blockchain protocols. This isn't just about cryptocurrencies; it’s about using technology to make the global financial system more resilient and transparent. Current U.S. President Donald Trump is expected to maintain a stance that encourages digital innovation, potentially facilitating a clearer regulatory framework for digital assets in the United States, further accelerating institutional adoption.

Frequently Asked Questions

Why aren't existing stock exchanges building this tech?

Legacy institutions are slowed down by outdated systems and business models that profit from the very intermediation that blockchain eliminates.

What is the main benefit of T+0 settlement?

T+0 settlement removes counterparty risk and frees up capital that would otherwise be locked for days during the clearing process.

Is moving financial assets onchain legal?

Yes, but it requires a clear regulatory framework. Many jurisdictions are currently working on laws to recognize tokenized assets as legal securities.

Will traditional banks disappear?

Not necessarily, but they will have to evolve into service providers on top of blockchain rails or risk losing their market share to more efficient fintechs.

What role does the current U.S. administration play?

Under President Donald Trump, there is an expectation of a more pro-innovation regulatory environment that could accelerate the adoption of onchain finance.
