The swaps market is valued at over 700 trillion dollars due to the notional value of derivatives, which reflects the total amounts owed in contracts rather than actual cash flows. This valuation can exceed global GDP because of leverage and the cancellation effects of risk exposure when positions are hedged against each other. While the net value of all global derivatives is theoretically zero, real-world events, such as the 2007 financial crisis, reveal that losses can exceed available funds, necessitating bailouts from external parties. This raises concerns about the sustainability of allowing investment banks and insurers to engage in high-risk bets without adequate capital reserves. The discussion highlights the complexities of valuing financial markets and the potential systemic risks involved.
