Yen's Surprise Rebound May Not Be Enough

The Japanese yen has made a surprising recovery in recent days, gaining about 3% against the US dollar over two days. This sudden uptick comes just over a month after Japan's authorities intervened heavily to support the currency.

Despite initial speculation that the Ministry of Finance might be returning to the market with fresh intervention, there is little evidence of this so far. Instead, the price action appears more consistent with a 'rate check', which can precede direct yen purchases.

The currency's gains have lacked the large, abrupt moves associated with previous interventions, and there have been no official or media indications that authorities are actively buying yen.

Expectations for tighter Bank of Japan policy appear to be playing a bigger role in the yen's recovery. Recent hawkish signals from policymakers have strengthened expectations for a rate increase at the September meeting, with money markets now pricing a greater than 50% chance of two 25-basis-point hikes by year-end.

Additionally, reports that Japan's Government Pension Investment Fund could rebalance its portfolio toward domestic assets may also support the currency. However, concerns surrounding Japan's fiscal outlook continue to weigh on the yen.
