August was turbulent for currency markets, with the US dollar weakening against nearly all major peers as the Federal Reserve signaled a pivotal shift in monetary policy. The lone exception was the New Zealand dollar, pressured by falling dairy prices—whole milk powder auctions slipped 3%—and the RBNZ’s forecast for earlier rate cuts amid unemployment climbing to 5.1%.
The driver of USD weakness was the Fed. While no FOMC meeting was scheduled in August, a series of developments confirmed a policy pivot toward easing. The release of July FOMC minutes on August 20 revealed that Governors Christopher Waller and Michelle Bowman favored a 25 bps rate cut in response to a softening labor market, with unemployment ticking up to 4.3%. The committee ultimately held rates at 4.25–4.50%, but the shift in tone was clear. Core PCE inflation remained sticky at 2.7%, yet the Fed emphasized employment risks over price stability.
The pivot was underscored two days later when the Fed revised its Statement on Longer-Run Goals and Monetary Policy Strategy, stressing flexibility and a willingness to act “forcefully” rather than rigidly pursuing the 2% inflation target. This change came against the backdrop of new US tariffs on 69 countries (effective August 7, lifting average rates to 18.4%, the highest since 1933) and a cooling jobs market. The Fed also finalized tougher bank capital requirements (effective October 1) to shore up financial stability. Together, these moves confirmed that easing had entered the Fed’s playbook, weakening the USD as markets repriced the outlook.
At Jackson Hole on August 22, Chair Jerome Powell cemented this dovish turn. He described a “challenging” balance between rising unemployment and tariff-driven inflation pressures, and noted that policy “may warrant adjustment.” Powell dropped earlier references to the effective lower bound and acknowledged tariffs’ inflationary impact, but stressed data-dependence without promising cuts. Markets heard enough: Fed funds futures priced a 90% chance of a September cut and 56 bps of easing by year-end. Powell’s reaffirmation of Fed independence calmed nerves but highlighted the risks of external shocks driving policy.
Those risks materialized just days later. On August 25, President Trump attempted to dismiss Fed Governor Lisa Cook “for cause,” alleging false statements on her mortgage application. Cook, who denied the charges, sued both Trump and the Fed, arguing the move lacked legal basis. Markets quickly drew comparisons to Turkey’s “Erdogan moment,” recalling how President Erdogan repeatedly fired central bank governors from 2018 onward to enforce unorthodox low-rate policies despite inflation above 20%. Those interventions triggered a collapse in the lira and long-lasting damage to investor confidence. Trump’s action raised fears of political interference in US monetary policy, with potential long-term consequences for the dollar if the Fed is seen as politicized.
The controversy comes as the Fed reassesses its inflation framework. The 2% target, first adopted by New Zealand in 1989 and embraced by the Fed in 2012, was designed to anchor expectations and avoid deflationary spirals. At this level, inflation is modest enough not to disrupt spending power while providing space for real wage growth and policy maneuvering.
Yet over time, policy has eroded the USD’s value in multiple ways. Inflation steadily reduces purchasing power—a dollar today buys only what $0.82 did a decade ago—but debasement also occurs when governments spend beyond their means and central banks finance that spending. Quantitative easing (QE), which expands the Fed’s balance sheet by creating new reserves to buy government debt, effectively increases the money supply and dilutes existing currency. Together, persistent deficits and monetary expansion magnify long-term debasement even if inflation appears “contained.”
Some analysts argue that the true “hurdle rate” required to fully offset currency debasement—including inflation, fiscal deficits, and money printing—would need to be much higher than official policy rates, possibly in the 12–15% range. While the Fed continues to describe policy as restrictive, signaling rates above neutral, markets are aware that official rates are far below what would be required to fully counter structural debasement. The monetary metals—gold and silver—are already sniffing this out, resuming their upward trend after a long period of sideways consolidation, with gold breaking higher. Their strength suggests investors see through the official 2% inflation narrative and are positioning for further erosion of fiat purchasing power.
Supporters of the Fed’s flexible approach argue that easing prevents deflationary traps and stabilizes markets during shocks. Critics counter that these measures are a hidden tax on savers, transferring wealth from holders of cash and bonds to debtors—including governments—while undermining long-term trust in the currency.
September’s FX outlook hinges on US data and geopolitics. The nonfarm payrolls report (September 5) will be pivotal—weak job creation would lock in expectations for rate cuts, extending USD weakness. At the same time, tariff escalation could reintroduce inflation fears, potentially limiting the Fed’s scope for easing and providing dollar support. Beyond the US, the ECB and BoJ meetings bear watching, as the euro and yen remain highly sensitive to Fed policy. With August’s volatility as the backdrop, markets enter the fall bracing for more turbulence.
