Initial panic over the MFN drug pricing scheme was based on pegging U.S. prices to the lowest in the industrialized world. The actual proposal is far less drastic, targeting the second-lowest price among a small cohort of high-income nations (G7 plus Denmark and Switzerland), a significantly less onerous benchmark.

The administration is leveraging the U.S.'s market power to demand "most favored nation" pricing from pharmaceutical companies. This forces them to offer drugs at the lowest price available in any other developed nation, slashing costs for American consumers.

While MFN may encourage value-based deals globally, it creates an implementation hurdle. MFN policies reference a simple price per unit (SKU), but value-based agreements are outcome-dependent. This makes calculating and reporting a single, compliant "net price" to the US government incredibly complex and operationally burdensome.

While MFN pricing is seen as a major threat, it could have an unexpected positive effect. It would force companies launching new drugs to establish a GDP-adjusted global price from the start, ending the current system where the U.S. effectively subsidizes lower prices elsewhere.

The Most Favored Nation (MFN) policy forces a difficult choice: launch early in Europe and risk a lower US reference price, or delay the European launch to protect US revenue, slowing patient access. This dilemma upends traditional global launch strategies, creating commercial, ethical, and operational problems for pharma companies.

CEOs are in an awkward position, supporting the administration in public but asking Congress not to codify the Most Favored Nation drug pricing policy. They fear legislation would create a permanent, stricter, and more broadly applied version than their private deals with the White House.

The large gap between insulin's list and net price was driven by Pharmacy Benefit Managers (PBMs). Their business model, which takes a percentage of the rebate, incentivized pharma to raise list prices to offer bigger discounts.

The Most Favored Nation (MFN) policy was strategically designed to be disruptive. The aim was less about implementing a specific pricing framework and more about forcing the pharmaceutical industry to change its behavior, re-evaluate global strategies, and engage in new types of negotiations, which has already proven effective.

MFN's pressure on global pricing will change how innovation is valued. Truly disruptive drugs may command higher prices ex-US, while incremental "me-too" drugs in crowded classes will not. This will force pharma companies to shift R&D investment away from iterative improvements and toward therapies with radical treatment-disrupting potential.
