Where the Action Began

At 20:30 Beijing time on August 19, international precious metals prices, led by gold, spiked sharply upward—a textbook event-driven rally. While this reinforces the narrative strength of the medium-to-long-term uptrend, it remains primarily a short-term reaction, and investors should be cautious of a potential pullback following the surge.

On August 19, the U.S. Treasury Department announced plans to at least double the size of its liquidity support repurchase operations for long-dated nominal coupon securities, covering two maturity buckets: 10-to-20-year and 20-to-30-year tenors. Key terms include: the previous maximum size per operation was $2 billion; the new minimum size per operation rises to at least $4 billion; the effective date is September 9, 2026; the coverage window extends through the current refinancing quarter, ending November 4, 2026; and the Treasury will disclose future repurchase sizes at the next quarterly refunding meeting on November 4, 2026.

What Triggered the Move

The most immediate catalyst was the Treasury's announcement that it would at least double its buyback operations for 10-to-30-year Treasuries starting September 9. This directly pulled down long-end Treasury yields, weakened the U.S. dollar, lowered the holding cost of precious metals, and boosted demand for safe-haven and credit-risk-hedging assets. This aligns with our previously identified second core factor in gold's medium-to-long-term uptrend: "fiscal deficit and debt expansion" (see our August 13, 2026 report, "Gold: Extreme Adversity, But Not Yet Recovery").

On August 19, COMEX gold futures settled at $4,545.3 per ounce, up 2.82% on the day, with an intraday high of $4,582.8 per ounce, breaking through the key $4,500 round-number level. COMEX silver futures settled at $65.825 per ounce, up 2.79% on the day. On the Shanghai Futures Exchange, gold's night session closed at 969.50 yuan per gram, up 2.13%, with an intraday high of 974.52 yuan per gram; silver's night session closed at 16,027 yuan per kilogram, up 2.58%, with an intraday high of 16,128 yuan per kilogram.

Why This Move Matters

The significance of last night's rally lies not in the single-day gain itself, but in the price reclaiming key resistance levels while simultaneously forming the typical risk-pricing combination of "precious metals rising + dollar falling + long-end Treasury yields declining." The dollar index closed at 98.73, down 0.82% on the day, marking a stage low; the 30-year Treasury yield fell to 5.19%, notably down from this week's high of 5.31%.

The Transmission Mechanism

The logic flows as follows: Treasury expands long-duration buybacks → long-end liquidity improves → 30-year Treasury yield declines. The speed and magnitude of the long-end yield decline are the most direct validation of this transmission. On August 19, the 30-year Treasury yield fell 9 basis points to 5.19%, and the 10-year yield fell 6 basis points to 4.65%. The 30-year had touched 5.31% intraday on August 17, the highest level since 2007. This suggests the market has begun pricing in concerns over supply-demand imbalances in long-dated U.S. Treasuries, particularly the 30-year "long-duration" tranche. By expanding buybacks, the Treasury provides a thicker absorption force in the secondary market, pushing long-end prices up and yields down.

Simultaneously, long-end yield declines directly erode the relative return of dollar assets. As long-end yields fell, the dollar index closed at 98.73 (-0.82%) on August 19, hitting a cyclical low. Lower gold holding costs + stronger expectations of declining real rates + a weaker dollar → higher gold valuation. As a non-interest-bearing asset, gold's opportunity cost equals the real interest rate. When the 30-year yield drops 9 basis points in a single day, the 10-year drops 6 basis points, and the real rate center shifts lower, gold's carrying cost clearly declines, and the "discount rate" in valuation falls accordingly.

The Deeper Logic

The deeper logic lies in the credit risk premium. This expansion of buyback capacity reveals a fact often overlooked by the market: the U.S. Treasury has begun actively managing long-end financing conditions rather than passively waiting for the market to clear. Once the market interprets this behavior as "U.S. fiscal-monetary policy coordination strengthening supply management at the long end," marginal pressure signals on the dollar credit system will accumulate. Under this narrative framework, gold is not simply being traded as a "safe-haven asset" but is being repriced as a hedge against long-term confidence in the dollar system—the common underlying theme of the past two gold bull markets (2002-2011 and 2019-2024).

Core Thesis

The essence of this gold rally is a dollar credit issue and insufficient demand for long-dated U.S. Treasuries. The market is not merely trading a policy announcement; it is progressively trading the larger narrative that "the U.S. must continuously provide liquidity support to maintain long-end financing stability." If this assessment holds, then gold's rise is not a simple "rate-cut trade" but a repricing of monetary credit and fiscal constraints. Since June, the 30-year Treasury yield and the dollar index have exhibited a long-term positive correlation (underpinned by the fundamental logic that "rising rates support the dollar")—a hallmark sign of policy-side "proactive support at the long end" breaking convention. For gold, this combined movement of rates and the dollar is more powerful than a pure safe-haven trade because both the valuation anchor (real rates) and the pricing currency (dollar) improve simultaneously, significantly amplifying the magnitude of repricing.

Counterfactual Test

Question: If the U.S. Treasury had not expanded its buybacks, or if the buyback signal had not been interpreted by the market as support for long-end liquidity, would precious metals still have risen?

Answer: Yes, but the gain would have been significantly smaller. Three reasons: First, gold and silver had already begun strengthening in mid-August on cooling rate-hike expectations, but the intraday slope remained gentle. Second, what catalyzed the move from a "trend rebound" into an "overnight surge" was precisely the policy-side explicit response to long-end Treasury pressure. Third, without the buyback expansion, the decline in long-end yields would have been very limited (the market could only rely on the Fed's monetary side), making it difficult to form the "simultaneous downward" combination of real rates and the dollar, and the repair to precious metals valuations would have been notably weaker. In other words, the "above-expectation incremental information" at the event level was the true accelerator of last night's sharp rally.

The Preheating Background

Although the trigger on the evening of August 19 was the Treasury's long-duration buyback arrangement, without the prior macro expectation groundwork, the price elasticity of this news would not have been so significant. A key recent backdrop: after the weaker-than-expected July nonfarm payrolls report, market expectations for a September FOMC rate hike cooled notably. Market observers suggest that while the market had previously priced in a September hike, the probability has clearly declined following the payrolls release, allowing precious metals to break free from the two-month range-bound consolidation.

After the July payrolls report, the FedWatch September rate-hike probability fell from approximately 57% to 44%. Meanwhile, the 10-year TIPS yield declined from 2.47% to 2.40%, global gold ETF net inflows rose from 5 tonnes to 19 tonnes, and COMEX non-commercial net long positions as a percentage of total open interest increased from 47.30% to 53.20%. Additionally, Bloomberg's year-end rate change expectation declined from its 1.786 high. This indicates that at the macro level, the market had begun shifting from "more hikes ahead" to "likely no more hikes this year," prompting gold to initiate valuation repair ahead of schedule. This is consistent with our earlier assessment of the third-quarter market theme: "Interest Rate Hike or Cut" (see our July 6, 2026 report, "Precious Metals: Q3 Price Outlook (Part II) Three Main Themes"), namely that "the core driver of gold price repair in Q3 is not real rate declines, but a systematic downward revision of rate expectations, driving gold's forward discount rate progressively lower... Q3 market expectations shift from 'more hikes ahead' to 'likely no more hikes this year.'"

This backdrop is crucial because it determines the direction of the news impact: if the market firmly believed rate hikes would continue to strengthen, the Treasury's buyback expansion would only be viewed as a technical patch for the bond market, and precious metals would show limited elasticity. But when the market has gradually accepted the expectation that "policy will not tighten further," any action helping to lower long-end yields is quickly converted into a bullish signal for gold. In other words, the August 19 evening rally was event-triggered, but the prior cooling of rate-hike expectations provided the "preheating foundation" for the advance.

The Secondary Pressure: FOMC Minutes

The FOMC July meeting minutes, released simultaneously on the evening of August 19, struck a hawkish tone, with several participants still seeing upside risks to inflation and cautioning against prematurely signaling rate cuts. The minutes showed that Fed officials had begun discussing some of the broader topics Chair Warsh has pushed, including potential reforms to how the Fed operates. Participants viewed the upcoming review of the Fed's balance sheet management as "an opportunity for a comprehensive discussion." However, "many" participants "reaffirmed that the primary means of adjusting the stance of monetary policy should be changes to the federal funds rate target range," rather than altering policy stance through adjustments to the Fed's asset holdings. Warsh also requested "committee input" on whether the Fed should reduce its annual policy meetings from the current eight to six, allowing a full two months of data accumulation between each meeting. No decision has been made on this matter, and the 2026 meeting schedule will not change.

However, because the long-duration Treasury issue created a stronger pulse, it offset the downward pressure on gold prices from the minutes. Precious metals did not weaken that evening. The core reasons: the buyback event is of higher significance than the minutes—Treasury policy represents a "fiscal-monetary" coordination action, while FOMC minutes reflect a "monetary pace" stance; in the "credit vs. rates" trade-off, the former carries greater weight. The "fiscal dominance" narrative has already taken shape: the market no longer treats the Fed's statements as the sole anchor but prices in "fiscal + monetary + political uncertainty" as an integrated framework. The minutes themselves offered limited marginal increment: the July FOMC meeting was already hawkish, and the minutes merely restated the existing stance without introducing new tightening signals.

Therefore, the FOMC July minutes are a secondary factor in this event and do not constitute a major constraint. However, this highlights a key risk window: the late-August Jackson Hole central bank symposium and the September FOMC meeting could still provide clearer policy direction signals and are critical observation points for the subsequent trend.

Conclusion: Guarding Against Pullbacks Post-Event, Higher Lows in the Medium-to-Long Term

This report focuses on commentary on last night's event; the intraday continuation of the rally is weak. If gold repeatedly retests the $4,500 level without breaking below it, the breakout is valid, and the metal may continue to probe the $4,580+ region. Conversely, if it quickly falls back below $4,500, this round is more likely to be defined as a news-driven overshoot. Currently, we maintain our earlier view of range-bound trading for the third quarter.

In the short term (before end-September), the most critical question is not the magnitude of gold's gain, but whether the rally can convert from an event-driven pulse into a platform lift. Viewed through a medium-term lens, this event does not change the medium-term trend; rather, it strengthens the intensity of the long-term uptrend and lifts the medium-to-long-term base higher. The core driver of this event (Treasury buybacks) is consistent with our previously identified second core factor in gold's medium-to-long-term uptrend: "fiscal deficit and debt expansion" (see our August 13, 2026 report, "Gold: Extreme Adversity, But Not Yet Recovery"). It is a concrete trigger of expectations, not an isolated event outside the three-pillar framework.

On strategy, we maintain our earlier approach: "Sell volatility before events, buy direction after pullbacks." Specifically: 1) Sell strangle options; 2) Accumulator options; 3) Buy on pullbacks; 4) Go long on the internal/external ratio.
