John Authers calls bond markets across developed economies a "slow-motion car wreck" in his latest Bloomberg Opinion piece. What started as a regional problem has gone global, with Japan now caught in the turmoil. The columnist warns this isn't a sudden crash but a grinding unraveling that's become impossible to ignore across asset classes.

Authers, a former Financial Times markets commentator, argues the damage compounds as investor confidence erodes. Bond markets from Tokyo to New York face simultaneous stress, creating a rare synchronized selloff. For institutions holding large sovereign debt portfolios, the mounting losses threaten balance sheets and risk models built on stability.

Pension funds, banks, and insurers face real pain with limited tools to stem the bleeding. Authers makes clear this slow-motion crisis carries genuine systemic risk if policymakers misread the pace of deterioration.
