#AI #ChatGPT #Grok: With no risk weighted bank capital requirements and instead a leverage ratio of 10:1, where would the Western world be?
I asked ChatGPT:
In less than 300 words:
"Please speculate on where the Western world’s nations could be, had the Basel Committee never introduced in 1988 risk weighted bank capital/equity requirements, and instead required 10 percent of equity against all bank assets… a leverage ratio of 10:1?"
ChatGPT answered:
"Had the Basel Committee in 1988 imposed a simple, non–risk-weighted 10 percent equity requirement against all bank assets, the Western world’s financial trajectory would likely look markedly different.
First, credit allocation would probably have been less distorted. Risk-weighting systematically favored sovereign debt and residential mortgages over loans to small businesses, entrepreneurs, and productive but riskier activities. A flat leverage ratio would have removed regulatory arbitrage incentives, encouraging banks to assess risk through pricing and due diligence rather than by chasing low-risk-weight assets. This could have produced a more balanced growth path, with relatively more financing for innovation, SMEs, and capital formation, and less structural bias toward housing and public debt accumulation.
Second, financial cycles may have been milder. Higher, uniform equity buffers would have made banks more resilient across the board, reducing the amplitude of booms and busts. The 2008 global financial crisis might not have been avoided, but its severity and fiscal aftershocks would likely have been substantially reduced, with fewer taxpayer-funded rescues and less post-crisis financial repression.
Third, central banking itself might have evolved differently. With banks less fragile and less concentrated in government bonds and mortgages, monetary policy transmission would rely less on asset price inflation and more on genuine credit intermediation. This could have constrained the long-run expansion of public debt and limited the political economy pressures for ultra-low interest rates.
In short, a simple 10:1 leverage rule could have yielded a Western financial system that is plainer, more competitive, less crisis-prone, and more oriented toward productive risk-taking—arguably closer to the market-disciplined capitalism that underpinned earlier Western development."

Grok answered:
"If the Basel Committee had mandated a flat 10% equity requirement against all bank assets—a 10:1 leverage ratio—instead of risk-weighted capital in 1988, Western nations might exhibit greater financial stability but slower economic growth.
Banks would face uniform capital costs, eliminating incentives to game risk weights by loading up on "safe" assets like government bonds or mortgage-backed securities that later proved toxic. This could have averted or mitigated the 2008 Global Financial Crisis, as excessive leverage in risky derivatives and subprime loans would be curbed—banks couldn't amplify returns without proportional equity buffers. Crises like the Savings & Loan debacle or Eurozone debt issues might have been less severe, fostering resilient banking systems less prone to bailouts.
However, credit expansion would likely be restrained. With no discounts for low-risk assets, lending for housing, infrastructure, or business might cost more, dampening booms in real estate and consumer spending. GDP growth in the US, UK, and EU could lag 1-2% annually over decades, per some economic models, prioritizing caution over innovation. Shadow banking might flourish to evade rules, shifting risks outside regulation.
Overall, Western economies might be more equitable and stable, with reduced inequality from fewer asset bubbles, but at the expense of dynamism—resembling pre-1980s conservatism rather than the high-leverage globalization era. Public debt might be lower, as governments couldn't rely on banks hoarding cheap sovereign bonds. In essence, a safer but staider financial world."
