Why offering citizens a 30% shareholding rarely fixes what’s wrong with leasing a national port to a private operator
There’s an old logical puzzle, devised by the philosopher Bertrand Russell, about a village barber who shaves everyone who doesn’t shave themselves and only those people. The question of who shaves the barber turns out to have no consistent answer. The rule, taken at face value, quietly contradicts itself.
Government port deals don’t usually contain a logical contradiction of that kind. But they do contain something that often gets mistaken for one: an arrangement that sounds, on paper, like it solves the problem it’s meant to solve, while the fine print does something close to the opposite. A government leases a strategic port to a foreign or private operator for thirty years, and softens the deal by offering citizens the right to buy up to 30% of the operating company. It sounds like a compromise sovereignty traded for cash, but with the public kept inside the tent. Look at how two real ports were actually structured, and the compromise turns out to be doing far less work than it appears to.
Two Ports, One Pattern
Sri Lanka’s Hambantota Port is the case most people reach for, and for good reason: it almost exactly matches the structure under discussion. Unable to keep servicing the Chinese loans that built the port, Sri Lanka signed a 2017 agreement leasing a 70% stake to China Merchants Port Holdings for 99 years, in exchange for a payment of roughly $1.12 billion.
The remaining 30% stayed in Sri Lankan hands, held by the state’s own ports authority rather than sold to the public directly. Critics on the ground called it a sellout of national assets, and the deal triggered protests, accusations that the government had quietly mortgaged sovereignty, and persistent concern that the port’s location on a major Indian Ocean shipping route gave it value as much strategic as commercial.
Greece’s Piraeus Port offers a second, slightly different version of the same shape. Facing bailout conditions after its debt crisis, Greece sold 51% of the Piraeus Port Authority to China’s COSCO in 2016, rising to 67% by 2021, with the Greek privatisation fund and private investors holding the rest. A dockworker quoted at the time put the objection bluntly: control of the country’s largest port had effectively passed to a foreign state-linked company, while Greek workers absorbed the disruption of subcontracted, less secure employment.
Where the 30% Stake Actually Fails
1. A minority stake is not a seat at the table
Thirty percent ownership sounds substantial until you ask what it’s thirty percent of. Board control, tariff-setting, hiring policy, and investment decisions are governed by majority ownership and by the operating concession both of which sit with the private partner. In Piraeus, COSCO’s climb from 51% to 67% control came with no equivalent strengthening of Greek shareholder power; the minority stake stayed a minority stake throughout. The public, or the state acting on its behalf, gets a dividend cheque and a seat in the room, not a vote that can outweigh the majority owner’s.
2. The money flows in a circle that mostly excludes the public
At Piraeus, COSCO’s local subsidiary paid an annual fee for use of two container piers. Once COSCO’s ownership stake rose past majority control, much of that fee began returning to COSCO itself rather than reaching the Greek state or its citizens, a dynamic the local dockworkers’ union pointed out at the time. The structure of a leaseback-plus-shareholding deal makes this almost inevitable: when the lessee and the majority shareholder become the same entity, payments that look like revenue to the public are substantially revenue to the private partner paying itself.
3. “Can buy” quietly becomes “must pay”
A right to purchase shares is not the same as a free distribution of them. If citizens have to buy in at a market-set price, the government has converted a sovereign asset into a private one and then offered the public the chance to buy back a slice of what was, until recently, theirs by right frequently using pension funds or household savings to do it. Who sets that price matters enormously, and the seller and the buyer’s counterparty are, in this structure, the same government negotiating both sides at once.
4. Thirty years outlives the government that signs it
This is the closest thing to a genuine structural paradox in the whole arrangement, even if it isn’t a logical one in Russell’s sense. The government that signs a thirty-year lease collects the upfront payment now. The costs foregone long-term revenue, reduced strategic control, terms that can’t be revisited as circumstances change, are paid by future governments and citizens who never agreed to the deal and typically can’t renegotiate it. Sri Lanka’s own experience shows how real this is: a newly elected government in 2019 wanted the port back on national-interest grounds, and by 2021 Sri Lankan officials were instead discussing extending the lease to nearly two centuries rather than shortening it. The original decision-maker and the people living with the consequences are simply not the same people, across enough time that ordinary democratic accountability can’t reach back and correct it.
5. Strategic control doesn’t show up on the balance sheet
Ports are not ordinary commercial assets. They are customs chokepoints, trade infrastructure, and in some cases potential military assets. Both Hambantota and Piraeus drew sustained concern contested in both cases, but persistent regardless about whether a foreign, state-linked operator’s commercial presence could translate into strategic leverage. A dividend stream, however reliably paid, is simply the wrong instrument to address a control question. Offering the public 30% of the equity answers a question about revenue-sharing; it does not answer the question of who decides what happens at the port during a crisis.
What the Stake Is Actually For
None of this means a thirty-year lease with a public shareholding option is necessarily a bad deal in every circumstance both Piraeus and Hambantota brought real investment, and Piraeus in particular saw genuine increases in cargo volume and port rankings after privatisation. The question worth asking is what the 30% stake is actually doing in the agreement. In practice, across both cases examined here, it functions less as a safeguard and more as a piece of political design: a number large enough to be announced as meaningful public participation, while remaining small enough to leave control, and the bulk of the economic upside, with the majority partner. The Greek government built in some genuine protections beyond the shareholding itself security veto rights over which ships could dock, and binding investment commitments attached to the lease which suggests the safeguards that matter are usually contractual and operational, not a minority equity stake dressed up as one.
If a government wants the public to have real influence over a strategic asset, the honest tools are a majority stake, a binding veto over specific categories of decision, a break clause tied to enforceable conditions, or a lease term short enough that one electoral cycle can correct another’s mistake. A 30% share purchase option offers something that looks like all of these at once and is, in practical terms, none of them.
