The Trading Game

Gary Stevenson · 2024

Thesis

The post-2008 economy did not recover because wealth kept flowing to those who already had it, draining spending from everyone else, and a young trader from East London made a fortune betting on that failure before concluding that the system rewarding him was the problem.

The main ideas

Trading desks reward a narrow skill, reading what will happen to prices, not understanding or improving the economy.
After 2008, Stevenson bet that interest rates would stay low far longer than forecasters expected.
His reasoning was that rising inequality drains demand: money concentrated among the rich is saved and invested in assets rather than spent.
The best insights came from watching the real economy, not from economic theory.
The money and status of trading came at a heavy cost in health, relationships and conscience, and banks make it hard to leave.
Inequality, in Stevenson's view, is the central economic problem, and a wealth tax is the remedy.

The trading game

Gary Stevenson grew up in a working-class family in Ilford, East London, and studied mathematics and economics at the London School of Economics. There he entered a student competition run by Citibank called the Trading Game, a card game built around trading. He won, and the prize led to an internship and then, in 2008, a job on Citi's short-term interest rate trading desk in London, at about 21.

The book, published in 2024, describes the desk and its culture: long hours, heavy drinking, abrasive colleagues and very large sums of money. Its characters include Caleb, the young head of the team who hired him, and a mentor he calls Bill, a rare working-class trader in the building.

Stevenson presents trading as a game in the literal sense. A trader's task is to anticipate what other people will do and what prices will do as a result. Understanding the economy matters only insofar as it predicts prices.

Implication: judge a trader's success by what it measures, a talent for anticipating prices, not by any contribution to the economy.

The real economy

Stevenson's mentor, in his account, taught him to look at what was actually happening in the economy rather than at what models and forecasters said should happen. Official forecasts after the 2008 crisis repeatedly predicted a recovery, with rising growth and interest rates.

Stevenson looked instead at his own world: the families he grew up among in East London, whose incomes and spending were stagnating, and the wealthy, whose fortunes were growing. He concluded that ordinary households did not have the money to drive a recovery.

The mechanism is that forecasters relied on models of how economies normally recover, while the conditions of ordinary life suggested that the normal pattern had broken.

Implication: when forecasts and what you can see around you disagree, take what you can see seriously. It may be evidence the models are missing.

The bet on inequality

Stevenson's trade was to bet that interest rates would stay low much longer than the market expected. Rates, he reasoned, were a close proxy for whether the economy would recover: they would rise only if growth returned.

His argument was about inequality. When wealth flows to the rich, they save and invest it, buying assets such as property and shares, rather than spending it. Ordinary households, whose share is shrinking, cannot spend enough to drive growth, and many borrow from the rich to maintain their living standards. Demand stays weak, so the economy stagnates and central banks keep rates low. Low rates, in turn, push up asset prices and enrich those who already own assets.

He claims that his bet made him Citibank's most profitable trader in 2011.

Implication: if wealth is concentrating, expect weak growth and rising asset prices together, and do not assume that a recovery in markets means a recovery for most people.

The cost

The book is subtitled A Confession. Stevenson describes how the job consumed him: exhaustion, isolation from friends and family, and growing unease about profiting from an economic decline that was harming the people he grew up with.

When he tried to leave, he found it difficult. In his account, the bank's deferred pay, held back for years and forfeited by those who quit, kept traders tied to their desks. Reviewers singled out his description of how hard banks make it to quit.

He left trading in 2014.

Implication: when an employer defers large parts of your pay, understand that it is designed to keep you, and weigh what staying will cost you beyond money.

From trader to campaigner

After leaving the bank, Stevenson studied economics at the University of Oxford, writing on how inequality affects asset prices. In 2020 he started a YouTube channel, GarysEconomics, which grew to well over a million subscribers, and he campaigns for a tax of about 1 to 2 percent a year on fortunes above £10 million.

His argument is that inequality is not a side issue but the central problem of modern economies, because the concentration of wealth weakens demand, drives up asset prices and reduces most people's living standards. Unless it is reversed, he argues, the pattern he profited from will continue.

Implication: when judging economic policy, ask how it affects the distribution of wealth, not only total growth.

Limits

Its central claim about his own success is disputed. In September 2024 the Financial Times reported that eight of his former colleagues at Citi disputed that he was the bank's most profitable trader, several doubting he was among the top ten in its foreign-exchange division, and noting that the bank kept no official ranking.
Its account of the bank is one-sided. A former colleague wrote that Stevenson had been loved and nurtured at Citigroup and did not recognize the world the book portrays.
Its economics is contested. Critics, including the Institute of Economic Affairs, argue that his account of inequality and his case for a wealth tax are too simple, and the book is mostly memoir rather than economic argument.
