Open Access Mandate

Access policy — instantiates Bottleneck Power Governance

Imposes a duty to let third parties onto an otherwise-closed network or platform on reasonable terms, turning a proprietary chokepoint into shared infrastructure and a stepping-stone off it.

An Open Access Mandate answers the prior question the tariff assumes away: must the controller let others in at all? It imposes a duty on the owner of a closed network, platform, or data gatekeeper to admit qualifying third parties on reasonable terms — and it is designed so that admitting them creates the competition that erodes the bottleneck itself. Its defining move is the pairing of a defined access obligation with an explicit entry-and-substitution purpose: opening the local loop, the rail track, or the banking API is not an end in itself but the means by which rivals can build a business on top of the chokepoint and, over time, route around it. Where the Non-Discrimination Access Tariff governs the terms of access, this mandate creates the right to it and aims that right at making the monopoly less necessary tomorrow than it is today.

Example

For decades a customer's bank held the only usable interface to that customer's own account data; anyone wanting to build a budgeting app, a lending check, or a payment service had to go through the bank, which had every reason to say no to a would-be competitor. An open access mandate — the shape of the EU's PSD2 and the UK's Open Banking regime — flips the default: a licensed third-party provider that a customer authorizes must be granted access to that account, through a defined interface, on non-prohibitive terms.

The mandate specifies the obligation concretely: who qualifies (a regulated, customer-authorized provider), what the bank must expose (balance and transaction data, payment initiation), the timeline, and what counts as a legitimate refusal (fraud, security). Within a couple of years an ecosystem of account aggregators and payment apps exists that could not have before — and, crucially, some of them grow into services that reduce customers' dependence on the incumbent bank entirely. That second effect, not the mere fact of access, is what the mandate is for.

How it works

  • Define the obligation. Spell out who qualifies for access, what must be provided, the quality and timeline owed, and the narrow, stated grounds on which the controller may legitimately refuse.
  • Target a specific layer. Name the interface, network element, or dataset that must open — the local loop, the API, the track slot — rather than "the platform" in the abstract.
  • Aim it at entry. Choose the access point whose opening lets third parties actually build and compete, not just observe, so the mandate manufactures rivals rather than tenants.
  • Treat access as transitional. Frame regulated access as a ladder toward independent, facilities-based alternatives, so the remedy works toward its own obsolescence rather than freezing dependence in place.

Tuning parameters

  • Access depth — shallow (read-only, high in the stack) versus deep (the core network element). Deeper access enables more genuine competition but concedes more of the incumbent's asset and blunts its incentive to invest.
  • Eligibility breadth — who counts as a qualifying third party. Broad eligibility maximizes entry; narrow, licensed eligibility protects security and quality at the cost of some competition.
  • Transition stance — access as a permanent utility versus a temporary ladder toward substitutes. The ladder framing pushes rivals to build their own facilities; the utility framing accepts durable dependence on the bottleneck.
  • Reasonableness of terms — how much the mandate itself constrains price and conditions versus leaving them to a separate tariff. Leaving them open risks access that is granted but priced or shaped into uselessness.

When it helps, and when it misleads

Its strength is that it attacks the bottleneck at the root: by admitting rivals it manufactures the alternatives whose absence created the monopoly problem, and where it works the eventual result is less need for ongoing regulation, not more. It is the natural remedy when the chokepoint is a platform, standard, or dataset that others could productively build on if only they were let in.

It misleads when access becomes a permanent substitute for competition rather than a path to it — rivals settle into renting the incumbent's facility forever, the incumbent loses the incentive to upgrade an asset its competitors free-ride on, and no independent alternative ever emerges. This is the "ladder of investment" concern: regulated access is meant to be climbed and left behind, not lived on.[1] It also fails quietly when the door is opened but the terms are not governed — access granted at a prohibitive price or degraded quality is refusal by other means, which is exactly why the mandate must be paired with a tariff. And it is sometimes run backwards as theatre: a token interface is opened, loudly, while the access that would actually enable entry stays shut.

How it implements the components

  • access_obligation_definition — the mandate is precisely this: a defined, reviewable duty stating who qualifies, what is owed, on what timeline, and when refusal is legitimate.
  • substitute_and_entry_creation_path — by choosing an access point that lets third parties build competing offers, the mandate is the archetype's primary engine for creating substitutes and future exit.

It sets the duty and its purpose but not the uniform price and service terms of access — those belong to Non-Discrimination Access Tariff and Price-Cap or Rate Review — and it stops short of restructuring the firm; when access duties are predictably evaded, Structural Separation or Unbundling is the stronger remedy.

Notes

Open access is close kin to the essential-facility and common-carriage rules, and the boundary is one of emphasis: those keep an existing facility open to eligible users, while an open access mandate is characteristically aimed at opening a proprietary platform or standard to reduce dependence on it. Read against the archetype's neighbours, it is a chokepoint-power remedy, not a network-adoption or channel-closure tool: the point is prying open a single point of control, not managing who wins a growth race.
