The Price You Pay

US Treasury support may contain long-term yields, but the resulting credibility cost should weaken the dollar as growth and monetary-policy expectations diverge across major economies.

• The Treasury buyback operation could exceed the announced $4 billion, but the CBO projects historically large deficits and debt reaching 120% of GDP by 2036, undermining claims of fiscal consolidation.
• Treasury intervention may cap long-end yields while blurring the line between improving market functioning and suppressing borrowing costs, creating downside pressure for the USD.
• The Eurozone composite PMI rose to a nine-month high of 52.1 in August, while markets priced a 25-basis-point ECB hike to 2.50% at the September 10 meeting and 60 basis points of tightening over twelve months.
• UK retail sales fell 0.5% month on month in July, but the composite PMI rose to a four-month high of 52.5; BBH views the 50 basis points of BOE hikes priced over twelve months as excessive despite support from the growth-inflation mix.
• Japan's composite PMI increased to 53.4 in August and core CPI excluding fresh food and energy rose 1.9% year on year in July, but both core inflation measures remained below the BOJ's 2.5% 2026 forecast and consumption was flat in the second quarter.

Takeaway: Investors should expect a weaker USD if US fiscal and Treasury-market intervention concerns intensify, while stronger European activity supports EUR and GBP and contained Japanese inflation limits the BOJ's tightening potential; upcoming US PMI data remains the near-term test for the dollar's growth advantage.
