Yen Intervention and Market Reaction
The Japanese yen surged 2.2% on Thursday, with the USD/JPY pair closing at 159.70 per dollar, marking its worst daily decline since April 30. A Nikkei Asia report confirmed that the Japanese government intervened by buying yen and selling dollars, corroborating market speculation that authorities had been on alert for yen‑buying. The yen had been trading above the 160 level since mid‑June, a key psychological threshold; crossing that mark earlier in the year prompted Tokyo to spend more than $70 billion in intervention during April and May. Earlier in the week the yen had slipped to a four‑decade low, prompting finance minister Satsuki Katayama to state readiness for “decisive action” against speculative moves.
U.S. Dollar Index and Federal Reserve Commentary
The U.S. dollar index fell 1% to 99.86, its lowest level since April 21, 2025. The decline was partly attributed to skepticism about Federal Reserve Chair Kevin Warsh’s statements on Wednesday, where he signaled a reluctance to raise policy rates despite inflationary pressures. Although the Fed held rates steady, three regional Fed presidents—Beth Hammack (Cleveland), Neel Kashkari (Minneapolis), and Lorie Logan (Dallas)—voted to raise the federal funds rate by 25 basis points, indicating internal dissent. Warsh described the FOMC discussion as a “good family fight” and highlighted persistent inflation, recent economic shocks, and monetary policy tools. Market strategist Thierry Wizman of Macquarie interpreted Warsh’s remarks as an attempt to delay rate hikes and substitute talk for action.
Treasury Yield Movements
Warsh noted that nominal and real yields across the U.S. Treasury curve had risen sharply, ranking among the top decile of increases in the past two decades. Following the Fed decision, longer‑end yields rose while shorter‑end, rate‑sensitive tenors fell. On Thursday, the benchmark 10‑year yield increased by more than 4 basis points to 4.666%, while the 2‑year yield slipped slightly to 4.234%.
Bank of England Decision and Eurozone Growth
In the United Kingdom, the Bank of England’s Monetary Policy Committee voted 6‑3 to keep the policy rate unchanged at 3.75%. The MPC noted that inflation had eased since the previous meeting but warned that price pressures could rise again due to the lingering effects of the Middle‑East energy shock. Sanjay Raja, chief UK economist at Deutsche Bank, said the decision did not alter his policy outlook, emphasizing the risk of a tightening cycle if energy prices continue to climb.
Currency Movements
The British pound gained 0.7% to settle at $1.3465 after the BoE’s hold decision. The euro rose 0.5% to $1.1525. Eurozone government data released that morning showed Q2 2026 GDP grew 0.4% quarter‑on‑quarter, with a year‑on‑year increase of 1.0%, both above expectations.
Outlook
Market participants now await the Bank of Japan’s interest‑rate decision on Friday for further clues on the yen’s trajectory, while the U.S. and European monetary authorities remain under pressure from evolving inflation dynamics and geopolitical energy concerns.
