The rise and fall of Silicon Valley Bank

The bank that held half of all venture-backed startups collapsed in under 24 hours — killed by a $15B bond bet and a WhatsApp panic.

What They Nailed Early

Built a brilliant flywheel: force startups to deposit all cash at SVB when taking loans. This gave them collateral, transaction insight, and network effects. By 2011, over half of all VC-backed tech startups banked with them.

What Changed

COVID money printing flooded Silicon Valley. Deposits grew 271% in two years. SVB parked $80B in low-yield government bonds at 1.79%. When the Fed raised rates to 4.5%, those bonds tanked. Meanwhile, they had no chief risk officer for eight months and removed interest rate hedges.

Where it Landed

Chapter 11 bankruptcy. Assets sold at fire-sale discount to First Citizens Bank. $40B withdrawn in one day. Greg Becker sold $3.6M in stock weeks before, then bought a $3M Hawaii vacation home.

The Principles

1. 
Concentration risk is existential. When 94% of depositors are uninsured and networked in group chats, a bank run moves at digital speed.
2. 
Playing with other people's chips breeds recklessness. Management took wild interest rate bets they'd never take with their own capital — classic principal-agent problem.
3. 
Regulatory relief can backfire catastrophically. SVB lobbied to relax stress tests in 2018. Those tests would have flagged the exact time bomb that killed them.

Builder's Takeaway

3 warning signs your risk management is theater:
• 
Key risk roles stay vacant while exposure multiplies
• 
You're removing hedges during the best times, not adding them
• 
Client concentration above 90% in one networked community
