The Wake-Up Call Britain Needs to Hear
Here’s a number that should worry Downing Street: £200 million. That’s how much tax revenue the UK stands to lose just from AstraZeneca upgrading its New York listing. And that’s just the beginning.
Investment bank Peel Hunt is sounding the alarm: scrap stamp duty on share trades, or watch Britain’s biggest companies pack their bags for Wall Street. Why? Because the US doesn’t charge stamp duty on stock trades, and UK companies are starting to notice.
AstraZeneca’s making the first move, but if it works out, expect a domino effect that could gut the London Stock Exchange and wipe out £4.5 billion in annual stamp duty receipts.
Why AstraZeneca’s Move Changes Everything
AstraZeneca isn’t abandoning London just yet, but it’s testing the waters. The pharma giant is upgrading from depositary receipts to a direct NYSE listing—a move that’ll shift more trading volume to New York.
No stamp duty in the US means lower trading costs. Lower costs mean more investors. More US trading volume could eventually make London irrelevant for AstraZeneca shares.
And here’s the kicker: if this strategy pays off, AstraZeneca might ditch its London listing entirely. That alone would slash stamp duty receipts by 5%.
Charles Hall, head of research at Peel Hunt stated: “Boards would be negligent if they did not consider this.”
The Domino Effect That Could Gut the FTSE
Think AstraZeneca’s an isolated case? Think again.
If Britain’s largest company successfully shifts trading volume to New York, every other FTSE 100 board will be asking the same question: why are we paying stamp duty when we don’t have to?
The math is simple. Stamp duty adds 0.5% to every share purchase in the UK. For institutional investors moving billions, that’s real money. Wall Street offers the same access to capital without the tax bill.
Britain’s already struggling to compete with New York’s deeper liquidity and higher valuations. Adding a tax disadvantage into the mix? That’s not a competitive edge—it’s a self-inflicted wound.
The £4.5 Billion Question
Stamp duty on shares currently brings in roughly £4.5 billion annually. Lose that, and the Treasury has a problem.
But Peel Hunt argues scrapping stamp duty could actually be revenue-positive. How? Higher equity valuations mean more capital gains tax when investors eventually sell. Plus, you keep the companies—and all the economic activity they generate—in the UK.
Hall frames it as an existential choice: “Do we want to have one of the leading equity markets in the world, and retain our largest companies, or are we prepared to let the revenues leave?”
It’s not just about tax receipts. Lose the FTSE heavyweights and you lose jobs, prestige, and Britain’s status as a global financial hub.
What Happens Next?
The ball’s in the government’s court. Stick with stamp duty and risk a slow-motion exodus to New York. Scrap it and gamble that higher valuations offset the lost revenue.
AstraZeneca’s move has shifted this from a theoretical debate to an urgent policy question. Other countries don’t charge stamp duty on shares. Britain does. That competitive disadvantage is now impossible to ignore.
The Treasury needs to act fast. Once a few major companies make the jump, momentum becomes hard to reverse.
Key Takeaways
Britain’s stamp duty on shares is pushing FTSE 100 companies toward New York. AstraZeneca’s NYSE upgrade could cost £200 million in tax receipts and trigger broader departures. Peel Hunt recommends scrapping the tax entirely—arguing that higher equity valuations would offset lost revenue. The government faces a choice: reform or watch London’s status as a leading stock exchange slowly evaporate.

FAQ: Stamp Duty and the FTSE Exodus
Q1: What is stamp duty on shares?
A: It’s a 0.5% tax charged on share purchases in the UK. Investors pay it when buying British stocks, but not when trading on US exchanges. This creates a cost disadvantage for London-listed companies.
Q2: Why is AstraZeneca upgrading its US listing?
A: To make it easier for American investors to trade its shares without paying UK stamp duty. This could shift trading volume from London to New York, reducing costs and potentially boosting liquidity.
Q3: How much revenue does stamp duty generate?
A: Around £4.5 billion annually. Losing major FTSE 100 companies to New York could significantly erode this figure.
Q4: Would scrapping stamp duty actually help the Treasury?
A: Peel Hunt argues yes—higher equity valuations from increased trading activity could generate more capital gains tax revenue. Plus, keeping major companies in London preserves broader economic benefits.
Q5: Could other FTSE 100 companies follow AstraZeneca?
A: Absolutely. If AstraZeneca’s strategy succeeds, other boards will face pressure to explore similar moves. No company wants to disadvantage its shareholders by paying avoidable taxes.
