Digital Debt Instruments: Nachrangdarlehen, Genussrechte and Bonds on a Platform

When companies refer to "digital bonds" or "tokenized debt," the terminology is often confused with crypto assets, DLT experiments, or speculative blockchain projects. In a regulated European context, digital debt instruments are something more precise: fixed income and debt-like securities structured under applicable law, issued and managed through compliant digital infrastructure rather than through traditional paper-based processes.

This guide explains what digital debt instruments are, how they differ from traditional bonds, what instrument types are available under German and EU law, and how regulated platforms handle the issuance workflow for each.

What Are Debt Instruments Issued by Corporations?

A debt instrument is a financial contract through which a company borrows capital from investors with an obligation to repay principal and, in most cases, pay interest over the life of the instrument. Unlike equity, debt does not grant ownership rights. The investor becomes a creditor rather than a shareholder.

Corporate debt instruments range from publicly traded bonds issued by large companies on regulated exchanges, to private placements of subordinated loans and profit participation rights used by SMEs to raise growth capital without going through a full public offering process.

In Germany, the most commonly used corporate debt instruments in the private markets context are Schuldverschreibungen (bonds), Nachrangdarlehen (subordinated loans), Genussrechte (profit participation rights), and Wandeldarlehen (convertible loans). Each carries distinct legal characteristics and regulatory treatment, and each can now be issued and managed digitally.

How Do Digital Bonds Work?

A digital bond works in the same way as a traditional bond in terms of its legal and economic character: the issuer borrows capital, commits to interest payments, and repays the principal at maturity. The difference is in how the instrument is created, recorded, and managed.

In a traditional bond issuance, the instrument exists as a paper certificate or a book entry in a central securities depository. Investor records are held by custodian banks. Transfers require coordination between multiple intermediaries. Reporting and compliance documentation are managed through external legal and administrative teams.

In a digital bond issuance under the German Electronic Securities Act (eWpG), the instrument is created as an electronic entry in a register maintained by a qualified registrar. There is no paper certificate. The investor register is maintained digitally, with each holder's record updated in real time. Subscription, transfer, and compliance workflows can be handled through a regulated platform, reducing the operational overhead associated with traditional issuance processes.

The economic terms are identical. What changes is the infrastructure through which those terms are administered.

Digital Bond vs Traditional Bond: What Actually Differs

The comparison between digital and traditional bonds is often framed around technology, but the substantive differences are operational and administrative rather than structural.

Issuance process: Traditional bonds typically require a prospectus, coordination with a lead bank, and registration with a central depository. Digital bonds under the eWpG can be issued with a simplified process using an electronic securities register, reducing the number of intermediaries involved.

Investor management: Traditional bonds held through custodian banks require issuers to work through intermediaries to communicate with investors or process corporate actions. Digital bonds issued through a platform allow direct investor register access, enabling more efficient communication and administration.

Secondary market transfers: Paper-based instruments require re-registration through notaries or custodians. Digital instruments can be transferred through the platform's register, with compliance checks applied at the point of transfer.

Cost and speed: Digital issuance removes several layers of intermediation, reducing the administrative cost and time required to complete an issuance. For smaller issuances that would not justify the overhead of a traditional bond process, digital infrastructure makes the economics viable.

What does not change is the legal standing of the instrument. A digital bond issued under the eWpG carries the same investor rights and creditor status as a paper bond. The "digital" refers to the format and management of the instrument, not to any reduction in its legal character.

German Debt Instruments: Nachrangdarlehen, Genussrechte, Wandeldarlehen and Schuldverschreibungen

The German private debt market uses a distinct set of instruments, each suited to different financing situations and investor profiles. Understanding how they differ is important for companies choosing the right structure for a digital issuance.

Nachrangdarlehen (subordinated loans) are contractual debt instruments where the lender's repayment claim ranks behind senior creditors in the event of insolvency. They carry a fixed interest rate and a defined repayment schedule, but are treated as equity-like capital for regulatory and accounting purposes due to their subordinated status. They are widely used in real estate, project finance, and SME growth financing. Nachrangdarlehen are contractual instruments rather than securities in the traditional sense, which means they can be documented and administered digitally without requiring a full securities issuance process.

Genussrechte (profit participation rights) sit between debt and equity. They grant investors a share of profits and, in some structures, a share of liquidation proceeds, but without conferring voting rights or ownership. They can be structured with fixed or variable returns, making them flexible for both issuer and investor. Under the eWpG, Genussrechte can be issued as electronic securities, removing the paper certificate requirement.

Wandeldarlehen (convertible loans) are hybrid instruments that start as debt and convert into equity at a defined trigger event, typically a qualified financing round. They are common in startup financing, where agreeing on a company valuation early is difficult. Digitally issued Wandeldarlehen can be managed through a platform that tracks both the debt phase and the conversion event.

Schuldverschreibungen (bonds or debentures) are the most traditional form of corporate debt instrument. They represent a fixed obligation to pay interest and repay principal, with no equity component. Under the eWpG, bearer bonds (Inhaberschuldverschreibungen) can now be issued as electronic securities, registered in a digital securities register without a physical certificate.

What Are DLT Bonds and How Do They Relate to Regulated Digital Debt?

DLT bonds are bonds where the instrument is recorded and settled on a distributed ledger technology system rather than a traditional central securities depository. In the EU, the DLT Pilot Regime, which came into force in 2023, created a regulatory sandbox for securities infrastructure using DLT, allowing approved operators to issue and settle DLT-based securities under supervised conditions.

DLT bonds are a subset of digital bonds, not the whole category. Most digital debt issuances in Europe, including those processed through ONINO, use conventional electronic register systems under the eWpG rather than DLT infrastructure. The eWpG framework covers the majority of practical digital debt issuances for SMEs, banks, and institutional issuers in Germany.

The distinction matters because DLT and blockchain are often used interchangeably with "digital" in financial media, creating the impression that digital securities require a blockchain. They do not. The eWpG framework provides a compliant basis for digital debt issuance that operates through regulated electronic registers, not public blockchains or crypto infrastructure.

What Changes When Debt Is Issued Digitally Through a Platform

For a company issuing a Nachrangdarlehen or Genussrecht through a regulated digital platform, the operational process changes substantially compared to a manual or paper-based issuance.

Investor onboarding is handled through the platform's digital workflow. Investors complete KYC verification and suitability assessments online, with all documentation retained in the platform's compliance system. The subscription process is automated: investors receive, review, and sign subscription agreements digitally, with each step timestamped and recorded.

The investor register is maintained in real time. As subscriptions are processed, investor records are updated immediately, eliminating the manual reconciliation step that creates errors in spreadsheet-based processes. For ongoing instrument management, interest payment schedules, investor communications, and corporate actions are administered through the platform rather than through external lawyers and administrators.

How Banks and Sparkassen Use Digital Debt Infrastructure

Banks and savings institutions (Sparkassen) are active participants in the digital debt market, both as issuers and as platform operators offering digital financing products to their clients.

For a bank acting as an issuer, digital infrastructure enables more efficient issuance of structured products, subordinated instruments, and client-specific financing solutions without the full overhead of a public bond programme. The reduced administrative cost makes smaller issuances economically viable.

For a bank acting as a platform operator, the white-label model allows the institution to offer digital debt products to its SME and corporate clients under its own brand. ONINO's infrastructure supports this model: the bank's clients access a branded digital financing platform, while ONINO provides the underlying issuance technology, compliance workflows, and regulatory framework.

Volksbank's partnership with ONINO is an example of this model operating at scale. The bank uses ONINO's infrastructure to offer regulated digital securities products to its clients, adding a digital financing capability to its existing product range without building the infrastructure internally.

FAQ

What is the difference between a Nachrangdarlehen and a Schuldverschreibung?

A Nachrangdarlehen is a contractual subordinated loan agreement between the issuer and the lender. It is not a security in the traditional sense and does not require a prospectus or securities registration in most cases. A Schuldverschreibung is a formal debt security that represents a standardised obligation to pay interest and repay principal. It is a security subject to securities law, and depending on the offering structure, may require a prospectus or registration. For smaller issuances targeting retail investors, Nachrangdarlehen are often preferred because of the simpler regulatory process.

Do digital bonds require blockchain technology?

No. In Germany, digital bonds can be issued under the eWpG using an electronic securities register that does not use blockchain or distributed ledger technology. DLT-based bonds are a separate category governed by the EU DLT Pilot Regime. Most practical digital debt issuances for SMEs and banks in Germany use conventional electronic register systems rather than blockchain infrastructure.

What is the eWpG and which instruments does it cover?

The Gesetz über elektronische Wertpapiere (eWpG) is the German Electronic Securities Act, which came into force in 2021. It created the legal basis for issuing bearer bonds (Inhaberschuldverschreibungen) and fund units as electronic securities without paper certificates. The Act also established the framework for crypto securities registered on a DLT system. Nachrangdarlehen and Genussrechte, being contractual or non-standardised instruments, sit outside the eWpG framework but can still be administered digitally through compliant platforms.

Can a company issue multiple debt instruments simultaneously on a platform?

Yes. A regulated digital platform can manage multiple active issuances simultaneously, with separate investor registers, compliance workflows, and reporting for each instrument. This is a significant operational advantage over manual processes, where running parallel issuances requires managing multiple spreadsheets, email threads, and document sets. Platform-based management centralises all instruments in one system.

What investor protections apply to digital debt instruments?

Digital debt instruments issued through a regulated platform carry the same investor protections as their paper-based equivalents. These include KYC and AML checks at investor onboarding, suitability assessments for retail investors, disclosure obligations under applicable securities law, and audit trails for all investor transactions. The platform enforces these requirements as part of the issuance workflow, rather than leaving compliance to the issuer to manage separately.

Is a Wandeldarlehen suitable for digital issuance?

Yes. A Wandeldarlehen can be documented and managed digitally. The platform handles the debt phase of the instrument, including interest accrual and investor records, and can be configured to manage the conversion event when it occurs. For startup financing rounds where Wandeldarlehen are common, digital management reduces the administrative overhead of tracking multiple investors across conversion triggers and financing rounds.

Summary

Digital debt instruments are not a crypto product. They are conventional corporate debt structures, including Nachrangdarlehen, Genussrechte, Wandeldarlehen, and electronic bonds, administered through compliant digital infrastructure rather than paper-based processes. The legal character of the instrument does not change. What changes is the efficiency and auditability of how it is issued and managed.

The German market provides a well-developed legal framework for digital debt issuance. The eWpG covers electronic bonds and fund units. Nachrangdarlehen and Genussrechte, as contractual instruments, sit outside the formal securities framework but can be fully administered through regulated platforms. Each instrument type serves a different financing need and investor profile, and a well-configured platform can support all of them simultaneously.

For banks and Sparkassen, digital debt infrastructure opens the ability to offer structured financing products to SME clients without the full overhead of a traditional bond programme. For companies raising capital, it replaces the manual processes that make private debt issuance difficult to scale with a centralised, compliant system that handles investor onboarding, subscription, and ongoing management in one place.

ONINO supports digital debt issuance across all major German instrument types, providing the regulated infrastructure that companies and financial institutions need to operate in this market efficiently and compliantly.
