US dollar slides to multi-week lows as debasement fears mount

The US Dollar Index slid for a third straight session on Wednesday, dipping below the 98.70 level to trade near its lowest point in several weeks, as a convergence of fiscal concerns, yen carry trade unwinding, and rising rate expectations from other major central banks continued to erode confidence in the greenback.

The dollar's weakness comes despite broadly hawkish signals from the Federal Reserve. Markets are pricing in a roughly 60% probability of a rate hike at the Fed's September 16 meeting, yet the currency has failed to benefit — a divergence that analysts say points to deeper structural headwinds.economies

The Debasement Debate

Much of the pressure traces back to the US Treasury's August 19 announcement that it would at least double the maximum size of certain bond buyback operations. Treasury Secretary Scott Bessent told CNBC the buyback could exceed $4 billion, a move that triggered what analysts now call the "dollar debasement trade".reuters

Rabobank analysts noted that the dollar failed to rally even after a positive surprise in last week's nonfarm payrolls report. "The Dollar debasement debate which was triggered by US Treasury Secretary Bessent's bond intervention announcement on August 19 appears to have undermined confidence in the greenback," they wrote. MUFG flagged a similar disconnect, observing that the dollar index remains about 1% lower since the buyback announcement despite the short end of the yield curve pricing in more Fed rate hikes.fxstreet

Yen Carry Trade and Global Tightening

ING analysts pointed to a "very fragile" USD/JPY pair as another drag on the index, noting that macro hedge funds are positioning for a break below 150 on expectations that Japanese policymakers will deliver on tightening commitments as part of what they described as a "grand bargain with Washington".fxstreet

Adding to the pressure, the European Central Bank is widely expected to raise its deposit rate by 25 basis points to 2.5% on Thursday, September 10. Brown Brothers Harriman's Elias Haddad warned that "tightening by other major central banks limits policy divergence," reducing the scope for sustained dollar appreciation even if a Fed hike materializes.reuters+2

Gold and the Diversification Trade

The dollar's decline has provided a lift to gold, which rose over 1% on Wednesday to trade above $4,400 after three consecutive daily losses. UBS ↘ 2.03% analysts argued that the precious metal's strength reflects forces that extend well beyond near-term Fed decisions. "We view gold primarily as a portfolio hedge and diversifier, rather than as a tactical expression of the next Fed decision," the bank's Chief Investment Office wrote.kitco+1

UBS highlighted persistent central bank buying — with the People's Bank of China adding 650,000 ounces in August alone, its largest monthly purchase since October 2023 — and fiscal sustainability concerns as durable supports for gold prices. The bank maintained its target of $5,000 per ounce in the first half of 2027.kitco

With US producer and consumer price data due Thursday and Friday, markets face a week of crosscurrents. As OANDA's Kelvin Wong put it, "the gold market is seeing a short-term tug of war between buyers and sellers," while the debasement trade and fiscal deficit concerns "continue to provide support".economies
