Central banks reasserting regulatory authority over private credit markets and tech-driven finance; shift toward coordinated G20 oversight of systemic risks; potential rebalancing of power from tech giants to traditional financial regulators; emerging market vulnerability to capital flight if crisis occurs.
2008 financial crisis: similar warnings about interconnected leverage, asset bubbles (then housing/derivatives, now AI valuations), and fragile credit systems preceded systemic collapse; current scenario mirrors pre-2008 complacency despite clear risk signals.

Households face potential financial instability through reduced credit availability, higher borrowing costs, asset value volatility, and possible economic contraction if cascading market failures occur. Pension and investment portfolio values could decline significantly.

Potential for coordinated G20 policy responses including stricter capital requirements, leverage limits, and enhanced stress-testing protocols. Governments may face pressure to address unsustainable debt levels through fiscal consolidation.
