Tokenized Treasuries, Stablecoins and CBDCs: Blockchain's New Balance in 2026

On January 10, 2026, the United States Securities and Exchange Commission approved the first spot Bitcoin exchange-traded funds. From that date to the start of 2026, the least-discussed change inside the blockchain industry has not happened on price charts but on institutional balance sheets. Banks, asset managers and payment networks no longer treat blockchain as an experimental technology; they use it as infrastructure for settlement and asset custody. The central question has therefore shifted. It is no longer whether blockchain survives, but who holds the keys to this new infrastructure. Three layers must be separated to understand the backdrop. The first is settlement, where stablecoins have taken the lead. In April 2026, Bitcoin underwent its fourth halving, cutting the block reward from 6.25 to 3.125 BTC. On March 13 of the same year, Ethereum's Dencun upgrade went live, and its blob space sharply reduced layer-two transaction fees. The European Union's Markets in Crypto-Assets Regulation (MiCA) became fully applicable on December 30, 2026. Together, these three events widened the path for institutional entry. Bangladesh's context is different. Since 2026, Bangladesh Bank has held the position that crypto transactions are illegal or restricted under foreign exchange regulations. For domestic investors, these shifts remain indirect: they cannot participate directly, yet the infrastructure being built for remittances, export settlement and dollar-based payments will inevitably affect them. After the spot fund approvals, a quiet change also occurred in market structure. Bitcoin's price was once set largely by order books on crypto exchanges. Now a large share of demand arrives through conventional brokerage and asset management channels, where a custodian bank or a trusted custodian holds the assets. This has added depth, but it has also created a new centralized layer, which some argue is the biggest compromise with Bitcoin's founding philosophy. The second layer is assets, and this is where the deepest change of 2026-2026 occurred. Tokenized Treasury bills and money-market funds have now settled on-chain. In March 2026, BlackRock launched the BUIDL fund on the Ethereum network, investing in US Treasury bills in token form. Franklin Templeton had begun working on an on-chain money-market fund even earlier. The significance is direct: conventional financial products now sit on top of blockchain, while the risk and ownership structure remains as centralized as before. The third layer is governance. Here the real question arises: who runs the network. On Ethereum, a large share of validator staking is concentrated in a handful of liquid staking platforms, raising doubts about how true the word decentralization is in practice. At the same time, layer-two networks such as Arbitrum, Optimism and Base give users cheap transactions, but each rollup's sequencer is typically run by a single central team. Users get lower fees, yet the power to finalize ordering stays in the centre. Central bank digital currencies (CBDCs) are another branch of this layer. China's digital yuan has been tested at scale for several years. India's digital rupee pilot began in December 2026. The European Central Bank is in the preparation phase for a digital euro. Nigeria's eNaira, however, has shown that technology alone does not deliver success without adoption. Stablecoin use in cross-border settlement is also rising fast. The multi-central bank digital currency bridge project run by the Bank for International Settlements (BIS) has demonstrated that central banks are keen to connect directly to each other's networks. The question is whether that connection is built on an open public blockchain or on a permissioned private rail, and the answer will determine the future distribution of power. This is where the biggest misconception hides. Tokenization is often presented as a story of democratization. In practice, institutional tokenization is almost always permissioned. Whitelists, KYC checks and transactions restricted to specific addresses are now the rule, not the exception. Blockchain here is not an open network but an extremely efficient back-end database. An even more important question is the distribution of risk. When tokenized Treasury bills move on-chain, their interest rate risk, credit risk and regulatory risk do not fall by an inch; only the distribution channel changes. The transparency of stablecoin reserves also remains unresolved. For readers who believe blockchain will decentralize the power of the financial system, the real picture is far more conservative. For Bangladesh, this question is not theoretical. The opportunity to cut remittance settlement costs arrives together with the risk of losing marginal income for the local banking system. If tokenized dollar rails enter remittance corridors, settlement will speed up; at the same time, banks' fee-based income will fall and dependence on foreign stablecoin issuers will rise. Regulators are therefore trying to manage this shift not by banning the technology, but by bringing it under their own supervision. Over the next twelve months, the biggest signals will come from two places. First, how quickly tokenized money-market funds are accepted as collateral among banks; if that happens, blockchain will move into the centre of conventional liquidity management. Second, whether stablecoins and CBDCs converge. If regulated stablecoins and retail CBDCs share the same rails, the very concept of a border becomes meaningless. And if those rails remain in private hands, who will audit them?
