The yen unwind reaches New York

-3.00%

single-day change vs previous close

What happened that day?

  • On 5 August 2024 the S&P 500 fell 3%
  • A week earlier the Bank of Japan had raised rates, from a level that had sat near zero for a very long time
  • A large amount of money had been borrowed in cheap yen and put into assets elsewhere. When the yen gets dearer, that trade turns into a loss
  • Then the July US payrolls report came in worse than expected, adding a recession worry on top
  • To repay borrowed money you have to sell what you bought. That selling started in Japan and spread outward
  • The Nikkei fell by a double-digit percentage that day, a record one-day drop
  • The US recovered quickly — 8.49% down from the peak, made back within weeks
