The Inequality Doom Loop
When the rich get richer, interest rates stay at zero and the economy never recovers.
The Inequality Doom Loop is Stevenson's grand macroeconomic thesis, developed during his years at Citibank and refined into the trade that made him the bank's most profitable trader. The framework argues that rising wealth inequality creates a self-reinforcing cycle that suppresses economic growth, keeps interest rates near zero, and makes the rich richer while everyone else gets poorer.
The mechanism is straightforward: when wealth concentrates at the top, the wealthy save rather than spend because they already have everything they need. The rest of the population, whose wages are stagnating, cannot increase spending to compensate. This chronic demand shortfall means central banks cannot raise interest rates without triggering recession, so rates stay at zero. Zero rates inflate asset prices (stocks, bonds, real estate), making the wealthy even wealthier, which further concentrates wealth and deepens the loop.
Stevenson realized that this structural dynamic meant that markets were consistently wrong in forecasting interest rate increases, because they failed to account for the structural demand suppression caused by inequality. This insight became the basis for what he describes as betting on the slow collapse of living standards for ordinary people across the developed world.
- When the rich get richer and everyone else gets poorer, there is never enough spending power to drive prices up, so interest rates stay zero forever.
- Zero interest rates inflate asset prices, making the rich richer, which deepens the cycle.
- Markets consistently underestimate the duration of low rates because they fail to account for structural inequality.
- Central banks cannot raise rates in an economy with suppressed consumer demand without triggering recession.
- The economy is not a thermostat that self-corrects; inequality creates a broken feedback loop.
- Identify the Structural ImbalanceLook for situations where the standard narrative assumes self-correction, but structural forces prevent it. In macroeconomics, this was the assumption that low rates would stimulate growth and eventually allow rate normalization. In reality, inequality prevented the transmission mechanism from working.Pro tipPay attention to who actually benefits from the supposed solution. If the beneficiaries are already wealthy, the demand stimulus will be weak.
- Map the Feedback LoopTrace how the supposed solution reinforces the original problem. Low rates were supposed to stimulate growth, but they primarily inflated asset prices, benefiting the wealthy, whose increased wealth did not translate to increased spending, meaning rates had to stay low, further inflating assets.Pro tipDraw the loop on paper. If it circles back to the starting condition or makes it worse, you have found a doom loop.WarningDoom loops can be broken by exogenous shocks or policy changes. Always consider what could disrupt the cycle.
- Position Against the Consensus NarrativeOnce you identify a doom loop that the consensus does not recognize, position for the continuation of the loop. Stevenson consistently bet that interest rates would stay lower for longer than markets expected, because markets kept pricing in recovery that inequality would not allow.WarningBeing structurally right does not mean being right on timing. Build positions that can survive extended periods before the thesis plays out.
- Monitor for Loop Acceleration or DisruptionWatch for signs that the doom loop is intensifying (further wealth concentration, declining real wages, political instability) or potentially breaking (major fiscal redistribution, structural reform). Each year of evidence either validates or challenges your thesis.Pro tipThe strongest evidence for a doom loop is when the consensus keeps predicting recovery next year and it keeps not happening. Repeated forecast failure is a signal of structural misunderstanding.
Every year after 2008, markets and economists forecast that interest rates would normalize within two to three years as economic recovery took hold. Every year, they were wrong. Rates stayed near zero across the US, UK, Europe, and Japan for over a decade because the structural inequality that suppressed demand was never addressed.
When governments bailed out the banks, they saved the financial system but did not address the underlying wealth distribution that had caused the crisis. The bailouts restored asset prices and banker bonuses while ordinary people lost homes and jobs. Stevenson observed this firsthand as his colleagues celebrated multimillion-dollar bonuses while the economy around them crumbled.
Even after leaving Citibank in 2014, Stevenson continued betting on the doom loop from his bedroom. He maintained positions that interest rates would stay low and that inequality would continue worsening. Year after year through 2023, his thesis continued to prove correct as living standards declined, housing became unaffordable, and families struggled to feed their children.
Stevenson's macroeconomic awakening happened gradually during his time at Citibank. Growing up in working-class East London, he already had an intuitive understanding that economic recovery was not reaching ordinary families. As he studied the economy professionally and watched rate markets consistently price in recovery that never materialized, he began to formalize his understanding of why.
The critical insight crystallized when he recognized that the 2008 bailouts had saved the wealthy (who held financial assets) while doing little for ordinary people (whose wages were stagnating). This created a structural imbalance: the economy needed consumer spending to recover, but consumers had no money to spend. He wrote his thesis on two pieces of paper, put one in his desk drawer and one in his underwear drawer at home, and spent the next several years building the trade that would prove him right.
