During the week of May 11–15, 2026, financial markets were rocked by a series of significant events, including stronger-than-expected US inflation data, a change in Federal Reserve leadership, and a high-profile summit between US President Donald Trump and Chinese leader Xi Jinping [1][2]. Both the Consumer Price Index (CPI) and Producer Price Index (PPI) came in above expectations, reinforcing concerns that inflationary pressures in the US remain persistent [1][2]. Additionally, April Retail Sales rose by 0.5%, indicating resilient consumer spending despite elevated borrowing costs [2].
The Federal Reserve saw a leadership change as Kevin Warsh assumed the role of Fed chair on Friday, a move that, combined with the inflation data, led markets to abandon hopes for rate cuts in 2026 [1]. As a result, the US Dollar Index (DXY) rallied strongly, breaking above key resistance levels such as 104.80 and reaching fresh multi-week highs, with technical indicators pointing to further upside [1][2]. The dollar was the strongest against the New Zealand Dollar, appreciating by 1.26%, and also posted notable gains against the Australian Dollar (+1.05%), British Pound (+0.66%), and Euro (+0.42%) [2].
Currency markets reflected this dollar strength: EUR/USD fell toward the 1.1620 area, GBP/USD dropped near 1.3320, and USD/JPY advanced toward 158.80, a two-week high, supported by widening US-Japan yield differentials [2]. The Japanese Yen lost some of its safe-haven appeal as markets reacted positively to constructive headlines from the Trump-Xi summit, though both sources agree that the summit produced no substantive progress on key issues such as the Strait of Hormuz [1][2].
Geopolitical tensions, particularly regarding the US-Iran ceasefire and Middle East energy costs, remained in the background, contributing to market caution and weighing on European growth prospects [1][2]. Traders were advised to remain cautious on rate-sensitive assets, as the likelihood of policy easing had diminished, and to watch for volatility around geopolitical developments [1].
According to [1], 'the market's rate-cut dream for 2026 had been quietly buried,' while [2] notes that the stronger dollar and higher US yields pressured other major currencies and risk assets.
CONCLUSION
Hotter-than-expected US inflation data and the appointment of Kevin Warsh as Fed chair have led markets to abandon hopes for near-term rate cuts, fueling a strong rally in the US dollar. Persistent inflation and geopolitical uncertainties are expected to keep risk assets under pressure and support continued dollar strength in the near term.
