Goldman Sachs: The Dollar May Become a Pressure Relief Valve for U.S. Fiscal Strain

From a technical perspective, the U.S. dollar index remains trapped in a range-bound oscillation, with no clear trend in sight.

Dollar bears have found new arguments as the U.S. Treasury is perceived to be inclined to suppress long-term interest rates, potentially shifting market pressure to the foreign exchange market—thus, the dollar may become a potential "pressure relief valve."

Goldman Sachs' foreign exchange research team believes that the Treasury's intervention stance in the bond market may backfire, putting pressure on the dollar, which leads them to be bullish on gold and the Swiss franc. Deutsche Bank, on the other hand, characterizes the Treasury's repurchase operations as "soft financial repression," suggesting that this structurally undermines the dollar.

However, from a technical standpoint, the dollar index (DXY) remains stuck in a large range oscillation pattern, and the recent breach of the 200-day moving average carries limited significance, with foreign exchange volatility not showing signs of a trend shift.

Extreme market positions and the push from CTA trend-following strategies may have amplified the recent directional volatility of the dollar, but whether this trend can sustain remains uncertain.

Fiscal Intervention Turns FX Market into a "Pressure Relief Valve"

Goldman Sachs' foreign exchange research team argues that if the Treasury continues to demonstrate a protective stance towards the bond market, a country excessively nurturing its own bond market should bear a higher risk premium. Once the risk premium on the bond side is suppressed, it will inevitably seek an outlet, with the foreign exchange market becoming the most direct pressure point.

Deutsche Bank's George Saravelos echoes this logic. He characterizes the Treasury's bond repurchase operations as effectively "soft financial repression," aimed at suppressing long-term yields.

His core argument is that if Treasury prices are not "allowed" to adjust downward, the adjustment must occur elsewhere—specifically, for overseas holders, this outlet is the exchange rate, manifesting as a weaker dollar.

In terms of specific trading directions, Goldman Sachs' foreign exchange trading team believes that the current configuration favors gold the most, followed by the Swiss franc; if long-term yields experience a more sustained decline, emerging market arbitrage trades are also expected to benefit.

Technical Indicators of the Dollar

Despite the evolving narrative, the dollar remains an asset characterized by strong mean reversion. The DXY has currently returned to the middle of a large range—analysts view this as the "no advantage zone," where determining direction is most challenging.

The DXY recently breached the 200-day moving average, drawing widespread attention. However, the actual significance of this technical signal is questionable: the current trajectory of the 200-day moving average is essentially flat, and the dollar has been oscillating around this long-term average for years, diminishing the reference value of this signal.

The euro's movement is mirrored by the DXY—although it has regained the 200-day moving average, its overall pattern also exhibits characteristics of large range oscillation, lacking effective signals for a trend breakthrough.

Before the recent sell-off wave, dollar long positions were already significantly high; at the same time, euro shorts were also in an excessively short position before the euro's substantial jump. Such extreme positions likely amplified the market movements.

The mechanical selling from trend-following CTA strategies further exacerbated the dollar's downward movement. In range-bound assets, momentum strategies often act as short-term "amplifiers"—chasing volatility but ultimately failing to form a sustained trend.

Amidst the various narratives regarding the dollar's movement, the performance of implied foreign exchange volatility is intriguing—it does not reflect the market's recognition of institutional changes. Until the range is effectively broken, seeking trading opportunities from extreme positions, rather than betting on narrative directions, remains a more prudent strategy choice.
