Yen’s Uplift Signals Dollar’s Growing Weakness: Economists Warn

Last week’s attempt to boost the sagging yen wasn’t the first time the U.S. and Japan took such joint action, but the way they did it revealed weakness in the dollar’s global status, according to a top currency expert.

Yen’s Strengthening: A Clue of Dollar’s Erosion

■The New York Fed sold euro instead of dollar-denominated assets to buy yen, avoiding additional strain on Treasury markets.

■Tokyo refrained from selling Treasuries and tapped the Fed’s Foreign and International Monetary Authorities Repo Facility (FIMA), borrowing dollars against its Treasury holdings.

Scale and Strategic Rationale

■With a $2 trillion budget deficit this fiscal year, the U.S. continues to flood the market with debt, pushing long‑term yields higher.

■AI hyperscalers compete by issuing vast amounts of their own bonds, further tightening investor demand.

Impact on Treasury Markets: Rising Yields and Sustainability

■Investors see that Treasuries cannot be used in unlimited quantities, reducing their incentive to hold them.

■This perception signals a decline in dollar reserve attractiveness, prompting nations to seek alternatives.

Gold’s Resurgence as a Safe Haven

■Central banks are increasing gold reserves to hedge against fiscal, inflationary, and geopolitical risks.

■Tompkins notes that speculative price moves are slowing gold buying, yet the ability to conduct FX without U.S. market concerns may spur renewed demand.

Goldman Sachs’ Counterpoint: Dollar’s Network Strength

■The accessibility of FIMA underscores the dollar’s network effects and supporting infrastructure.

■The firm argues that the U.S. is unlikely to prevent other debt holders from selling Treasuries in the future.

Implications for European Investors

■A decline in the dollar as a reserve currency could directly influence Eurozone bond yields and risk premia.

■The European Central Bank may need to reassess its interest rate stance amid escalating global debt pressures.

The dollar’s dominance is being tested by such interventions; however, the growing search for alternative reserve currencies may ultimately reshape European markets as well.
