Japanese Yen: Stretched JPY shorts raise intervention risk – ABN AMRO

ABN AMRO’s Georgette Boele flags that speculative positioning in the Japanese Yen is very stretched, with large net shorts coinciding with USD/JPY trading near levels last seen in 1986. She argues that unilateral Japanese intervention would struggle against market forces, but rare joint action with US authorities could weaken USD/JPY significantly, especially in thin liquidity conditions.

Extreme shorts and intervention talk cap upside

"Positioning in the Japanese yen is also very stretched, with speculators holding large net short yen positions."

"This matters. Extreme yen positioning comes at a time when USD/JPY is near levels last seen in 1986, while US and Japanese officials have recently been discussing and signalling intervention risk again."

"If Japan were to intervene alone, it would be difficult to push back against the market unless the timing were ideal, for example during thin liquidity and when investors were already questioning whether the yen could weaken further."

"We think the market would find it much harder to resist joint intervention by the US and Japan. Such action would be rare, but it could weaken USD/JPY."
