The International Monetary Fund (IMF) on Thursday issued a stark warning: moving financial assets onto blockchain through tokenization could make markets faster and cheaper — but also more fragile. Tobias Adrian, head of the IMF's monetary and capital markets department, put it bluntly in a blog post: “Frictions disappear — but so do buffers.”
Speed and unified ledgers: the upside
Tokenization records assets like stocks, bonds and bank deposits on shared digital ledgers. Smart contracts execute trades, transfer ownership and process payments far quicker than in traditional finance (TradFi), where a single trade can take two or more days to clear, settle and reconcile across multiple institutions. With tokenized assets, the entire process completes in seconds.
Adrian noted that when a tokenized asset changes hands, smart contracts can execute trades, transfer ownership and move payments simultaneously on a shared ledger, compressing days of work into moments. Tokenization also enables different forms of digital money — tokenized bank deposits, fiat-pegged stablecoins, and tokenized central bank reserves — to function seamlessly as settlement assets on the same ledger, and allows high-quality assets to be quickly deployed as collateral across platforms.
Buffers gone: shock propagation outruns oversight
But the delays tokenization eliminates are not just inefficiencies. Adrian stressed they give banks, regulators and risk managers time to detect and stop problems. Remove that buffer, and a market shock, a coding error, or a sudden wave of automated selling could ripple through the system before anyone can intervene.
“Liquidity demands materialize in real time, collateral calls can be automated, and failures can propagate faster than institutions or supervisors can respond,” he wrote. Risks once absorbed by individual institutions' balance sheets become concentrated in the platforms and code governing transactions.
Concentration risk: infrastructure as a single point of failure
Adrian also flagged concentration risk. Tokenization tends to funnel activity onto fewer, larger platforms. “When infrastructure becomes the central hub, governance failures become systemic events,” he warned. On cybersecurity, he said consolidation onto shared ledgers amplifies the importance of operational resilience, cybersecurity and crisis management.
Instead of multiple layers of checks across different institutions, tokenization relies on a single platform architecture. A vulnerability in the code, a hack, or extreme market volatility could trigger a chain reaction that spreads instantly — without the traditional buffers to slow it down.
