Dollar Breaks From Rates as Yen Shock Triggers Capitulation

Kit Juckes, Chief FX Strategist at Societe Generale, discusses the balance between US political pressure and Japan’s fiscal constraints.

While the dollar decline has been punchy and one-sided, the move was already underway before last Friday’s speculation of a USD/JPY rate check. The greenback has fallen across the board, with NOK, AUD and NZD gaining the most ground so far this month. Yen strength ultimately accelerated the move, turning what had been steady dollar selling into an avalanche into the weekend, capped by a clear “gap-and-go” lower at the Sunday open.

But positioning and price action are now starting to look stretched. While Washington has touted a weaker dollar to support export competitiveness, markets have been reluctant to accept prolonged misalignments with rates. The dollar has now meaningfully detached from a weighted basket of two-year yields, a signal of extreme selling pressure rather than a deterioration in fundamentals.

A similar decoupling last appeared in the wake of the Liberation Day tariffs, when the greenback traded at a deep discount to rates-implied fair value, then had to spend the second half of last year clawing that ground back. That discount has now reemerged, despite US growth estimates remaining relatively firm and front-end rates showing little sign of imminent relief.

The dollar slid to its weakest level in nearly four years as US policy risks and a resurgent yen weigh against the world’s reserve currency.

The Bloomberg Dollar Spot Index fell as much as 0.7% to the lowest since March 2022. It’s the fourth-straight day of losses, setting up the dollar for its worst stretch since President Donald Trump unveiled his program of universal tariffs last April.

The weakness reflects investor caution amid unpredictable Washington policymaking, including Trump’s threats to take over Greenland. Longer-term, risks around Federal Reserve independence, a growing budget deficit, worries about fiscal profligacy and widening political polarization have all pulled the dollar lower.

“Structural drags on the dollar — fading confidence in US trade and security policy, politicization of the Fed, and worsening US fiscal credibility - could outweigh the more neutral cyclical dollar backdrop and pull the dollar lower,” said Elias Haddad, global head of markets strategy at Brown Brothers Harriman & Co.

The declines helped to fuel gains across global currency markets. The euro soared to its strongest level since June 2021, and the British pound jumped to its highest since October of that year. The yen was also stronger after Japanese officials offered further hints that they could intervene in the market.

That followed signs of US support to boost the yen, reopening speculation around the potential for coordinated currency intervention to guide the greenback lower against key trading partners. Reports from traders Friday indicated the Federal Reserve Bank of New York contacted financial institutions to check on the yen’s exchange rate — a preliminary step that’s often taken before interventions.

Friday’s rate-checking of the dollar-yen rate by Fed officials “drove down the US dollar further,” George Catrambone, head of fixed income at DWS Americas, told Bloomberg Radio on Tuesday.

The yen rallied some 0.7% to 153.03 Tuesday in New York. Japanese Finance Minister Satsuki Katayama, speaking after a Group-of-Seven meeting Tuesday, affirmed that the government will take appropriate action against currency moves in close coordination with US authorities if needed.

The drop in the dollar also buoyed the euro, which hit $1.1972 earlier, its strongest level since 2021. The pound rose 0.8% to $1.3791, also the highest since 2021, while the Swiss franc gained 1.4% to 0.7660 per dollar and continues to trade at its strongest mark since 2015.
