Berlin Space Protocol: Why Zero Ratifications After 14 Years Matters to Lenders

Institutional lenders are deploying capital into satellite assets under a secured lending framework. The recovery mechanics do not support that classification.

When a corporate borrower defaults, the lender's recovery path is established. Collateral is identified, seized, and liquidated. Loss given default (LGD) is estimated against a body of precedent, legal infrastructure, and liquid secondary markets. The process is imperfect. It is not structurally broken.

Satellite finance does not have this. What it has is the appearance of secured lending, with the underlying economics of unsecured exposure.

The Collateral Problem

A satellite in geostationary orbit sits 35,786 km from Earth. No enforcement mechanism in existence can physically retrieve it. No court order, no insolvency administrator, no secured creditor can access the asset.

Legal title can be reassigned on default. Operational control cannot. Operating a satellite requires licensed spectrum, ground station infrastructure, proprietary command protocols, and trained personnel. A lender holding legal title post-default has no path to monetising that title without the operator's technical apparatus. The asset is owned and functionally inaccessible simultaneously.

Spectrum and orbital slot rights compound this. The ITU allocates these to operators, not to lenders. On operator insolvency, those rights do not automatically transfer to the secured creditor. Regulatory bodies may reclaim or reassign them. The lender's collateral position can disappear at the precise moment enforcement is triggered.

The credit implication is direct. LGD for satellite-backed debt should be modelled at 80 to 100% in the absence of specific contractual protections. The market convention of applying secured infrastructure LGD assumptions of 40 to 60% is not supported by the recovery mechanics.

The Legal Framework That Does Not Yet Exist

There is a treaty designed to address this. The Berlin Space Protocol, adopted under UNIDROIT on 9 March 2012, was constructed to extend the Cape Town Convention's asset-based financing model to satellites and other space assets. It would have established an international registry for security interests, standardised default remedies, and critically, a mechanism for transferring operational control of a satellite to a creditor or replacement operator on default.

Fourteen years after adoption, it has not entered into force. The Protocol requires ten contracting states to take effect. It has four signatures: Burkina Faso, Germany, Saudi Arabia, and Zimbabwe. In November 2024, Paraguay became the first state to accede. One contracting state. Nine short of ten. No signatory has converted its signature into a ratification.

Compare this to the Aircraft Protocol, the aviation equivalent under the same Convention. It entered into force in 2006 and now has 85 contracting parties. Aviation lenders operate within an internationally enforceable secured lending regime. Satellite lenders do not.

Every satellite financing transaction today relies on bilateral contract drafting to approximate protections the Protocol was designed to standardise. Command code escrow provisions exist in some deals. Step-in rights vary by jurisdiction. Revenue assignment structures differ across every transaction. There is no international registry. There is no standardised enforcement path.

Payload Transfer: A Partial Solution With a Critical Constraint

Payload transfer is the most viable recovery mechanism available under current market structures. In hosted payload arrangements, the payload owner holds a legally distinct claim on their hardware. If the bus operator defaults, a well-drafted contract can allow a replacement operator to assume control, preserving asset utility and giving the lender a partial recovery path.

The mechanism works under four simultaneous conditions: the contract contains explicit step-in rights; ground station access and command authority are transferable; spectrum and orbital slot rights remain valid through the transition; and a qualified replacement operator exists and is willing to act within a commercially viable timeframe.

All four failing simultaneously is the base case in current market structures.

Where transfer is successfully executed, LGD can fall to 30 to 50%, a material improvement. But this scenario carries a constraint that is not legal or structural. It is informational.

A lender cannot decide whether to execute a payload transfer without knowing the asset's condition at the point of default. Remaining propellant mass, attitude control status, subsystem degradation, and radiation exposure history determine whether a transfer is worth executing. The window between default and value destruction can be weeks. Without continuous telemetry access, the lender cannot make a timely, informed decision. The payload transfer right exists on paper. The data to activate it does not exist in the lender's hands.

What Mispriced LGD Means for Capital Allocation

The systematic underestimation of LGD in satellite finance has measurable consequences.

Required yields are set below the level justified by true credit risk. Covenant packages are calibrated to secured infrastructure norms that do not apply. Portfolio-level concentration risk is underestimated because LGD correlations across satellite assets are not modelled against shared orbital and technical risk factors. Insurers pricing residual value risk face the same data gap as lenders.

As the satellite asset class scales, these mispricing effects compound. Over 14,000 active satellites are now in orbit. LEO constellation financing is accelerating. A credit event in a major constellation financing would surface this gap acutely.

The Data Infrastructure the Market Needs

The Berlin Space Protocol assumed that ratification would precede large-scale private satellite financing. That assumption has not held. Institutional capital is in the market now. The legal infrastructure is not.

What bridges this gap is not a legal instrument. It is a data layer. Continuous satellite telemetry, translated into credit risk outputs that an investment committee or credit officer can act on, converts a theoretical recovery right into an executable decision. It allows LGD to be modelled dynamically, not assumed statically. It identifies asset deterioration before default, not after. It gives the payload transfer mechanism the informational foundation it currently lacks.

This is the problem SarynSpace was built to solve. SFIS, our Space Finance Intelligence System, scores 12,129 satellite assets across 82 operators globally, translating orbital and financial data into institutional-grade credit outputs including probability of default at 1, 3, and 5-year horizons and portfolio-level LGD analytics.

The legal framework for satellite finance will eventually catch up. Until it does, the data layer is the only mechanism a lender has for pricing what they are actually holding.
