Financial Services Collapsed: $200T Banking Sector Down 55% When Interest Rate Economics Failed

Banking promised efficient financial intermediation and wealth creation.

Instead, banking collapsed when interest rate volatility destroyed the fundamental business model: borrow short-term, lend long-term at profitable spreads.

Banking valuations: Down 55%. Financial services jobs: 30M → 13.5M (-55%). Industry revenue: $500B → $225B (-55%).

When interest rates became volatile and unpredictable, banks' core business model became unprofitable. The entire financial services industry contracted.

The Collapse: From $500B to $225B

Metric	Peak (2021)	May 2026	Decline
Banking Revenue	$500B	$225B	-55%
Banking Job Losses	-	16.5M	-55%
Net Interest Margin	3-4%	1-2%	-50%
Bank Valuations	$3T	$1.35T	-55%

Banking didn't decline gradually. It collapsed when interest rate volatility made the core business model unprofitable.

Why Banking Failed

The Core Problem: Interest Rate Volatility

• Pre-2024: Rates stable 0-1% (post-2008 financial crisis)
• 2024-2026: Rates volatile 5-12% range
• Banks locked into low-rate mortgages; can't raise rates
• Result: Interest rate compression; profitability destroyed

The Real Problem: Net Interest Margin Collapsed

• Pre-2024: Net interest margin 3-4% (profitable)
• 2024-2026: Net interest margin 1-2% (marginally profitable/loss-making)
• Banking model requires 3%+ margin to be profitable
• Result: Most banks unprofitable

The Real Problem: Credit Default Risks Increased

• Inflation destroyed borrower credit quality
• Loan defaults increased 50-100%
• Banks increased loan loss reserves
• Result: Profitability further compressed

Lesson: Banking was a business model dependent on stable interest rate spreads. When interest rates became volatile and unpredictable, spreads compressed and banks became unprofitable.
