A combination of factors led to the collapse of SVB Bank; - The gradual increase of interest rates by the US Federal Reserve to curb rising inflation. As interest rates rise, long-term Government bonds lose value. SVB invested heavily in US Government bonds, and when interest rates spiked, the bonds lost value. - News of the bank's financial situation caused its clients to withdraw their funds quickly. - To mitigate the situation, SVB sold its bonds for significant losses. Within 48 hours, depositors had withdrawn enough money to cause the bank to collapse.
