BIS chief warns soaring debt, market changes could complicate future crisis response - Reuters

The head of the Bank for International Settlements has warned that rising public and private debt, combined with structural changes in financial markets, could make it harder for central banks and governments to respond effectively to the next crisis. The BIS, often described as the central bank of central banks, frames this as a capacity issue rather than a forecast of imminent trouble.

The concern rests on two pillars. First, high debt loads leave governments with less fiscal room to spend countercyclically, while heavily indebted households and firms may cut back further if borrowing costs rise. Second, market structure has shifted: liquidity is increasingly concentrated in fewer venues and participants, which can amplify moves during stress. Together, these factors could blunt the speed and force of traditional policy responses.

For markets, the takeaway is not a signal to act, but a reminder that policy backstops may be less powerful than in past cycles. Investors may therefore pay closer attention to debt sustainability metrics, credit spreads, and liquidity conditions.
