Arthur Hayes warns that Japanese yen strengthening driven by institutional repatriation could trigger global liquidity shocks and rapid repricing of risk assets.

Arthur Hayes has outlined a scenario in which strengthening of the Japanese yen—driven by domestic institutions repatriating capital from overseas assets—could trigger widespread liquidity disruptions across global markets. The mechanism draws on historical precedent: when Japan experiences major disasters, domestic insurers and pension funds typically accelerate the sale of foreign stocks and bonds to finance domestic rebuilding, forcing rapid yen conversion that simultaneously weakens other currencies and compresses risk asset valuations.
Hayes traces this dynamic through the 2011 earthquake and tsunami, when the yen spiked to post-World War II strength levels amid a near-20 percent drop in the Nikkei. The subsequent "Abenomics" program of the early 2010s aimed explicitly to reverse such yen appreciation through unlimited central bank bond purchases, yield curve control, and structural shifts in pension fund allocation toward foreign holdings—ultimately halving the yen's international purchasing power over time. Hayes argues that understanding this pattern of disaster-triggered repatriation cascades is essential for anticipating how sudden yen moves can rapidly reprice risk assets globally, though the specific catalysts and timing of such a shock remain uncertain.
