Dematerialisation of securities is the process of eliminating physical certificates so that securities exist only as electronic records. Once a security is dematerialised, there is no document to hold, deliver or lose: ownership is shown by a balance in an account, and a sale is completed by debiting the seller's account and crediting the buyer's. The term covers both the conversion of existing paper certificates into electronic form and the issue of new securities with no paper at all.
Dematerialised holdings are a kind of book-entry securities, recorded at a central securities depository or on an issuer's electronic register. The idea is often confused with immobilisation of securities, in which paper certificates, or a single global certificate for the whole issue, still exist but are locked in a depository's vault while transfers happen by book entry. Dematerialisation goes one step further and removes the paper entirely.
Background
Until the late twentieth century, shares and bonds were represented by certificates. A sale required the seller to deliver the certificate, with a signed transfer form for registered shares, and the registrar to issue a new one. As trading volumes grew, the movement of paper became a serious bottleneck. In the late 1960s, Wall Street firms fell so far behind that the exchanges shortened trading hours to let back offices catch up. The first response was immobilisation in central depositories; full dematerialisation followed where the law allowed.
France converted its securities to book-entry form in 1984, and the Nordic countries made similar moves in the same decade. In the United Kingdom, the CREST system has allowed shares to be held without certificates since 1996. India passed its Depositories Act in 1996 and moved almost all exchange trading to dematerialised settlement within a few years.
How the conversion works
The detail differs by country, but the usual pattern for an investor holding a certificate is as follows.
- The investor opens a securities account with an intermediary that is a member of the depository, called a depository participant in India.
- The investor hands over the certificate with a dematerialisation request.
- The intermediary sends the request electronically to the depository and the paper to the issuer or its registrar.
- The registrar checks the certificate against the share register, cancels it and enters the depository, or the investor, as holder in electronic form.
- The depository credits the investor's account, and the holding can then be traded and settled electronically.
The work that remains for securities still in paper form is described under physical securities processing. Some markets also allow the reverse step, rematerialisation, though it is rarely used.
Benefits
- Safety. Electronic records remove the risks of loss, theft, forgery and damage that affect paper, especially a bearer bond, which belongs to whoever holds it.
- Speed. Transfers are immediate, which makes short settlement cycles and delivery versus payment possible.
- Lower cost. Printing, storage, courier, insurance and stamp-handling costs disappear, and corporate actions can be applied automatically.
- Transparency. Electronic registers make it easier to identify holders and harder to hide ownership, which supports tax collection and anti-money laundering controls.
Legal and regulatory requirements
Dematerialisation needs a legal basis, because traditional company and property law tied ownership to the certificate or the register entry signed in ink. Enabling laws state that an account entry is proof of title and set out who is liable for errors. In the European Union, the Central Securities Depositories Regulation requires securities traded on trading venues to be recorded in book-entry form, either immobilised or dematerialised. The requirement applied to new issues from 1 January 2023 and to all such securities from 1 January 2025.
In India, the securities regulator has barred the transfer of listed shares held in paper form since 2019, with limited exceptions, which in practice forces holders to dematerialise before selling. The United States has largely immobilised rather than dematerialised its securities, although investors can also hold shares directly in electronic form on the issuer's books through the Direct Registration System.
Limits and newer developments
Dematerialisation changes what an investor holds. In many systems the name on the register is the depository's nominee or an intermediary, and the investor has an entitlement through an account rather than a direct claim on the issuer, which raises questions about voting and shareholder identification. Investors also depend on the integrity and resilience of the depository's systems, and some small or elderly shareholders have found the move away from paper difficult.
Records kept on distributed ledger technology are sometimes described as the next stage. Several countries, including Germany, France and Luxembourg, have changed their laws to allow tokenised securities to be issued on such ledgers without a traditional depository record, and the European Union runs a pilot regime for market infrastructures that use the technology for securities settlement.
