Free trade is about the freedom of people to transact as they wish, with whom they wish, and without politicians and bureaucrats as gatekeepers. Therefore, genuine free traders tend to be sceptical of agreements, which are usually more about managed trade than free trade.

Rather than liberalise the rules and provide consumers with greater choices, trade agreements too often contain provisions that protect incumbents from challengers by locking in existing advantages, requiring long tariff phase‐​out periods, and limiting competition in industries through rules that masquerade as serving prudential or socially desirable purposes.

Too often, the terms are pro‐​business, pro‐​labour, or pro‐​special interest, when they should be pro‐​market.

The prospect of a bilateral UK-US agreement affords two of the world’s largest economies — both traditionally committed to the institutions of free‐​market capitalism and the rule of law — the opportunity to break new ground and pioneer the rules of a genuinely liberalising, modern trade agreement.

By removing tariffs and significantly reducing behind the border barriers that inhibit market integration, such a model will have a transformative effect, on both economies and beyond.

With some limited exceptions, the final model for an ideal agreement calls for: zero tariffs on all goods; zero non‐​tariff trade barriers; zero restrictions on competition for government procurement and on foreign direct investment; rules to make mutual recognition of potentially protectionist product standards and regulations more feasible; prohibitions against the use of anti‐​dumping measures; and prohibitions against restrictions based on scientifically unsubstantiated public health and safety concerns and national security concerns that do not meet certain minimum standards.

Despite the current uncertainty in both the UK and US policy environments, now is the ideal time to be giving serious thought to a bilateral free trade agreement. In six months, the UK will have repatriated its trade policy decision‐​making. Striking smart, new trade agreements will be crucial for Britain to maximise economic opportunities post‐​Brexit.

Meanwhile, before the year’s end, the Trump administration is likely to wrap up its trade renegotiations with South Korea, Canada, and Mexico, clearing the decks for a shift in focus to new, bilateral free trade agreements.

The US ambassador to Britain noted last week that Trump has a “robust appetite” for a bilateral trade deal with the UK, which suggests that commencing negotiations in late March 2019 may very well be within the realm of possibilities.

It is difficult to imagine two countries that are better suited for a state‐​of‐​the‐​art, comprehensive, truly liberalising trade agreement than Britain and the US. And now the substance of that agreement has already been written.

Governments, it’s over to you now.
