Abstract:The Japanese Yen has emerged as the G10 leader amid rampant speculation of a coordinated intervention by US and Japanese authorities. Combined with threats of automotive tariffs, the currency market is bracing for enhanced volatility.

The currency markets are being whipped by a combination of policy intervention fears and aggressive trade posturing. The Japanese Yen (JPY) has surged to lead the G10 complex, while the Canadian Dollar (CAD) is reeling from existential threats to the USMCA trade agreement.
The Yen's sharp appreciation follows reports of high-level communication between US and Japanese treasury officials aimed at correcting “unwarranted depreciation.” Prime Minister Sanae Takaichis administration has explicitly warned it will combat speculative attacks, and the market is now pricing in a high probability of Bank of Japan (BoJ) policy tightening or direct FX intervention.
Meanwhile, the Canadian Dollar is under siege. President Trump‘s threat to levy a 100% tariff on all Canadian imports—retaliation for Ottawa’s potential trade dealings with China—has introduced a massive risk premium into USD/CAD.
