Serious attention from major financial institutions toward crypto is reaching a new phase. It’s no longer about whether they will enter, but about how they will integrate digital assets into existing banking systems.

Citigroup has just announced plans to launch institutional bitcoin custody services by the end of this year. What’s interesting isn’t only about storing bitcoin, but about a far more ambitious vision. Nisha Surendran, who leads the development of this product, explained that Citi’s goal is to make bitcoin tradable like traditional assets within their banking ecosystem.

Picture this: institutional clients no longer need to worry about managing private keys, wallets, or addresses. They simply give instructions to Citi through SWIFT, APIs, or standard interfaces, and the bank handles all the complexities behind the scenes. Bitcoin will flow into the same reporting and tax workflow systems as stocks and bonds. This is a fundamental change in how digital assets are accessed by institutional investors.

From a cross-margin perspective, Citi is building an account structure where different types of assets are all in one place: US securities, foreign bonds, tokenized money market funds, and bitcoin. This creates the possibility of using crypto assets as collateral on traditional exchanges—and vice versa.

Of course, Citi isn’t the only one moving. Morgan Stanley, which manages around $8 trillion in assets, is also expanding its presence in the crypto sector in a highly strategic way. Morgan Stanley crypto initiatives mereka include filing ETF products for bitcoin, ethereum, and solana. They are also exploring wallet technology across their wealth platforms, launching spot crypto trading on E*TRADE, and evaluating lending and yield opportunities related to digital assets.

Amy Golenberg, head of digital assets at Morgan Stanley, emphasized that they can’t just rent technology from third parties. They need to build this infrastructure internally. This shows a serious commitment from both institutions.

One of the most interesting parts is how both banks are preparing for a 24/7 market. Citi started with licensed private blockchains before expanding to public networks as regulations became clearer. They’ve even launched Citi Token Services, a blockchain-based network that operates 24/7 to move money within their global system. The logic is simple: if bitcoin operates 24/7, then digital dollars or digital money should also be available 24/7.

This demand comes from their own institutional clients. The NYSE has even announced plans to introduce a blockchain-based trading venue operating 24 hours for tokenized stocks by the end of this year. Nasdaq has also revealed similar plans to facilitate trading for nearly most of the day.

So what we’re seeing here is a fundamental transformation in how traditional and digital assets will coexist within the same financial infrastructure. Morgan Stanley’s crypto expansion and Citi’s initiatives are not just about adding new services. It’s about rebuilding the banking system for the 24/7 asset era. This trend will likely continue as more major institutions realize they can no longer ignore this sector.
