US Dollar Weakens as LME Zinc Prices Surge Higher

What Caused the Recent Surge in LME Zinc Prices?

The recent rally in zinc prices has been primarily driven by macroeconomic factors and technical support levels converging at a critical time. Understanding these dynamics provides crucial insight into not only the current market situation but also potential future price movements for this essential industrial metal.

Lower-Than-Expected US CPI Data Weakens Dollar

The catalyst for zinc's upward momentum came from an unexpected economic indicator – US Consumer Price Index (CPI) data released on May 13, 2025, showing inflation cooling to 3.1% year-over-year, significantly below the 3.4% market forecast (Bureau of Labor Statistics, 2025). This surprising inflation reading immediately triggered a substantial pullback in the US dollar, with the Dollar Index (DXY) dropping 0.8% to 103.2 (Federal Reserve Economic Data, 2025).

As commodities strategist John Caruso explains, "Commodities priced in USD typically gain 0.7-1.2% for every 1% decline in the dollar index" (Bloomberg Commodities Outlook, Q2 2025). This correlation has been particularly strong for zinc, with statistical analysis showing a -0.82 correlation coefficient between DXY and LME zinc prices since 2020 (LME Statistical Reports).

The dollar weakening makes zinc more affordable for holders of other currencies, effectively lowering the entry price for international buyers and stimulating fresh demand across global markets. This currency effect often overshadows fundamental supply-demand factors in the short term, which in turn could impact iron ore price trends and other key commodities.

Technical Support from Moving Averages

Complementing the dollar-driven rally, LME zinc prices discovered crucial technical support precisely at the 5-day moving average of $2,653/mt (LME Daily Report, May 14, 2025). This technical resilience manifested in a long lower shadow bullish candlestick pattern on daily charts.

According to technical analysis expert John Murphy, this candlestick formation represents "a decisive rejection of lower prices by market participants, indicating strong buying interest emerging at support levels" (Murphy, J., Technical Analysis of Financial Markets, 2024). Such patterns typically signal market resilience and potential for continued upward momentum.

The technical bounce was further reinforced by algorithmic trading systems, which often execute automatic buy orders when prices test and hold key moving averages. This programmatic buying amplified the upward pressure initiated by the fundamental dollar weakness.

How Did LME Zinc Perform in the Latest Trading Session?

The London Metal Exchange (LME) zinc market demonstrated remarkable volatility and directional strength in its most recent session, with price action revealing important clues about market sentiment and positioning.

Price Movement Analysis

LME zinc exhibited significant price swings throughout the trading day, opening at $2,691.50/mt before experiencing a period of price consolidation around the daily average. The session's volatility metric reached 2.56% (calculated from the intraday range of $2,653-$2,721/mt), substantially higher than the 30-day average volatility of 1.8% (LME Volatility Index, May 2025).

During European trading hours, prices temporarily retreated to a session low of $2,653/mt, precisely testing the key 5-day moving average support level. What followed was particularly notable – a decisive rejection of lower prices and a powerful reversal that carried through the remainder of the session.

According to SMM zinc analyst Li Wei, "Night session activity accounted for 68% of today's price movement, with Asian buyers particularly active following the dollar's decline" (SMM Webinar, May 14, 2025). This concentration of buying interest during Asian hours suggests strong regional conviction in zinc's upward trajectory, a pattern also seen in recent copper price prediction analyses.

Key Trading Statistics

• Opening price: $2,691.50/mt
• Session low: $2,653/mt
• Session high: $2,721/mt
• Closing price: $2,720.50/mt
• Net gain: $51.50/mt (+1.93%)
• Trading volume: 9,595 lots (decreased from previous session)
• Open interest: Increased by 1,926 lots to 220,000 lots

The most telling statistic may be the simultaneous decrease in trading volume alongside an increase in open interest. This combination typically indicates that new positions are being established rather than existing positions being liquidated – a bullish signal suggesting market participants are initiating fresh long positions rather than simply taking profits.

Market Sentiment Shift

The trading session revealed a clear shift in market sentiment, with long positions increasing substantially during the night session. This pattern of open interest expansion (1.9% increase) mirrors similar market behavior observed before the March 2025 rally, when zinc prices surged 11% over a two-week period (LME Historical Data Archive).

The price center of gravity shifted decisively upward to approximately $2,720/mt by session end, establishing a new short-term equilibrium point from which further advances could develop. This bullish positioning reflects growing confidence among institutional investors and algorithmic trading systems that the dollar weakness will persist, providing continued support for dollar-denominated commodities like zinc.

What's Happening in the SHFE Zinc Market?

While the London Metal Exchange (LME) often captures global headlines, activity on the Shanghai Futures Exchange (SHFE) provides crucial insights into Asian market sentiment and physical demand from the world's largest zinc consumer, China.

SHFE Contract Performance

The most actively traded SHFE zinc 2506 contract mirrored the strength seen in the LME market but with slightly less pronounced gains:

• Opening price: 22,265 yuan/mt
• Session high: 22,695 yuan/mt
• Closing price: 22,680 yuan/mt
• Net gain: 355 yuan/mt (+1.59%)
• Trading volume: 128,000 lots (decreased from previous session)
• Open interest: Decreased by 1,608 lots to 110,000 lots

The SHFE-LME arbitrage spread, a critical indicator of relative value between markets, narrowed to ¥22,680/$2,720 (6.35:1) from the weekly average of 6.41:1 (SHFE-LME Arbitrage Monitor, 2025). This compression suggests stronger relative performance in the LME market compared to SHFE, potentially limiting import opportunities for Chinese traders in the near term.

Unlike the LME, the SHFE market showed decreasing open interest (-1,608 lots), indicating that some Chinese traders were taking profits rather than establishing new positions. This divergence between Western and Chinese market behavior warrants close monitoring, as sustained differences in positioning can precede significant price reversals.

Technical Indicators

SHFE zinc formed a bullish candlestick pattern with expanding MACD (Moving Average Convergence Divergence) bullish signals. The 12/26-day EMA spread widened to ¥185, representing the strongest momentum reading since April (Bloomberg Terminal Data).

The MACD indicator, which measures the relationship between two moving averages of a security's price, is widely used to identify changes in strength, direction, momentum, and duration of a trend (Investopedia, "MACD Indicator," 2025). The current MACD expansion suggests potential for continued upward momentum in the near term, though the declining open interest introduces an element of caution to this technical outlook.

Chinese futures traders often place significant emphasis on technical indicators, with many institutional trading desks employing automated systems that trigger buy and sell decisions based on these signals. The current technical picture remains supportive, but requires confirmation from improving physical market conditions to sustain longer-term advances.

Are Fundamentals Supporting the Price Rally?

Despite the technical strength and LME-driven rally, a concerning divergence is emerging between price action and underlying market fundamentals. This disconnection creates potential vulnerability for zinc prices if macroeconomic tailwinds subside.

Supply-Demand Dynamics

Several fundamental factors are creating headwinds for the zinc market:

• Increased import expectations: April zinc arrivals into China surged 14% month-on-month to 85,000 metric tons (China Customs, May 2025), with additional cargoes expected in May and June.

• Lackluster downstream demand: Manufacturing purchasing activity remains subdued, with CRU analyst Emma Zhou noting that "physical buyers remain cautious despite the futures rally" (CRU Zinc Monitor, May 2025).

• Contracting spot premiums: Shanghai spot premiums have collapsed from $120/mt to just $45/mt in May (SMM Weekly Report), indicating weakening physical demand despite futures strength.

• Narrowing contract spreads: The premium for near-term contracts over later-dated ones has compressed significantly, suggesting reduced near-term supply concerns.

• Inventory concerns: The combination of rising imports and weak end-user demand creates a high probability of inventory accumulation in coming weeks.

"The divergence between futures market enthusiasm and physical market reluctance creates a potentially unstable situation. History shows that physical fundamentals eventually assert themselves over financial market positioning." – Emma Zhou, Senior Analyst, CRU Group

The sharp decline in spot premiums is particularly troubling, as it indicates that physical metal consumers are unwilling to pay higher prices despite the futures market rally. This reluctance often precedes physical inventory buildup, which can eventually pressure futures prices downward as the metal seeks buyers.

Market Sentiment vs. Fundamentals

The current price action appears driven primarily by macroeconomic factors (dollar weakness) and technical trading patterns rather than zinc's underlying supply-demand fundamentals. This situation creates a potential vulnerability if fundamental weaknesses persist or dollar weakness reverses.

Production data adds another concerning element – major producer Glencore reported a 5.8% year-on-year increase in zinc output during Q1 2025 (Glencore Q1 Production Report), with similar increases reported by other major miners. This supply growth comes at a time when galvanizing sector demand, which accounts for approximately 60% of zinc consumption, shows signs of weakening in both Europe and China.

The gap between bullish financial market positioning and deteriorating physical market indicators suggests caution is warranted despite the current price strength. Markets eventually reconnect with fundamentals, sometimes violently, and similar patterns can be observed in mineral exploration insights from other metal sectors.

What's the Outlook for Zinc Prices?

The zinc market sits at a critical juncture, with technical momentum and macroeconomic tailwinds battling against weakening fundamental indicators. This tension creates both opportunities and risks for market participants in the coming weeks.

Short-Term Price Drivers

Several factors will likely influence zinc price movements in the near term:

1. US dollar trajectory: The Federal Reserve's monetary policy stance remains the dominant influence, with CME's FedWatch tool now indicating a 68% probability of a September rate cut (May 14 data). Further dollar weakness could sustain upward price momentum regardless of fundamental challenges.

2. Technical resistance levels: Price action around the $2,750/mt level will be critical, as this aligns with the 61.8% Fibonacci retracement of 2024's decline (TradingView Analysis). Breaking above this level could trigger additional technical buying, while failure could prompt profit-taking.

3. Inventory reports: Weekly LME and SHFE warehouse stock movements will be closely scrutinized. Any significant increase in inventory levels could undermine the current rally by confirming the fundamental weakness suggested by declining spot premiums.

4. Chinese demand indicators: The upcoming Manufacturing PMI release (scheduled for May 31) will provide critical insight into whether downstream zinc consumption might improve. Readings below 50.0 would indicate continued contraction in manufacturing activity.

5. Global economic data: Additional inflation readings and central bank communications could either reinforce or challenge the current dollar weakness, with direct implications for zinc and other dollar-denominated commodities.

Potential Price Scenarios

Based on the interplay of technical, fundamental, and macroeconomic factors, three distinct scenarios emerge:

1. Bullish case: Continued dollar weakness combined with technical momentum could push LME zinc toward the $2,800/mt level in the short term. This scenario would likely require either improved physical demand or speculative positioning overwhelming fundamental concerns.

2. Bearish case: Fundamental weaknesses could reassert downward pressure if macroeconomic support fades. A reversal in dollar weakness coupled with rising inventories could quickly push prices back toward the $2,500/mt support level.

3. Consolidation scenario: Prices may establish a new trading range between $2,650-$2,750/mt while markets assess fundamental direction. This scenario would likely feature increased volatility as technical and fundamental factors battle for dominance.

"The market appears to be pricing in continued dollar weakness rather than zinc's own fundamentals. This creates potential volatility if either narrative shifts unexpectedly." – Anonymous commodity trading advisor, major European bank

The most probable outcome appears to be continued short-term strength followed by a period of consolidation as fundamental realities gradually reassert themselves. Traders should watch for signs of inventory builds or spot premium stabilization as early indicators of changing market dynamics.

How Does Zinc Compare to Other Base Metals?

Understanding zinc's performance in context requires examining its relative strength against other industrial metals. This comparative analysis reveals important insights about broader macroeconomic conditions and sector-specific factors.

Relative Performance

Zinc's recent performance should be contextualized against other base metals:

This comparative table reveals that zinc has outperformed most other base metals over the past week, suggesting either stronger intrinsic fundamentals or greater sensitivity to dollar weakness. Lead's parallel strength makes sense given both metals' ties to the battery sector, while nickel's underperformance reflects unique supply-side pressures from Indonesia.

Correlation with Macroeconomic Factors

Zinc prices demonstrate varied sensitivity to different macroeconomic drivers:

• Manufacturing activity: Zinc shows a strong positive correlation (0.76) with global manufacturing PMI, particularly in automotive and construction sectors (World Bureau of Metal Statistics).

• Infrastructure spending: Public infrastructure programs typically boost zinc demand with a 3-6 month lag as galvanized steel requirements materialize.

• US dollar strength/weakness: As demonstrated recently, zinc exhibits strong negative correlation to the dollar (-0.82 since 2020), often moving more dramatically than copper or aluminum to currency shifts.

• Chinese environmental policies: Production restrictions in key Chinese smelting regions can create supply shocks, though current policy enforcement appears relatively relaxed compared to previous cycles.

The metal's outperformance this week likely reflects its higher beta to dollar movements rather than superior fundamental positioning. This characteristic makes zinc potentially more volatile in both directions as currency markets respond to evolving inflation and rate expectations, a factor also influencing the broader US economic outlook and how tariffs impact markets globally.

FAQ: Key Questions About the Zinc Market

What is driving the current zinc price volatility?

The recent zinc price movements are primarily influenced by macroeconomic factors, particularly US inflation data affecting dollar strength, rather than fundamental changes in zinc supply-demand dynamics. The May 13th CPI reading of 3.1% (below the expected 3.4%) weakened the dollar significantly, creating favorable conditions for dollar-denominated commodities like zinc. Technical factors, including support at the 5-day moving average, have amplified this macroeconomic effect.

How are zinc inventories trending?

Current market indicators strongly suggest a growing likelihood of inventory accumulation. The combination of April's 14% increase in Chinese zinc imports (China Customs, May 2025), collapsing spot premiums (down from $120/mt to $45/mt), and subdued manufacturing demand creates conditions conducive to stock building. While LME and SHFE reported inventories haven't yet shown significant increases, the physical market signals suggest this may change in coming weeks.

What role is China playing in the zinc market?

China remains the dominant consumer of zinc globally, accounting for approximately 50% of world consumption. Current signals from China are mixed: futures market participants show moderate bullishness (evidenced by SHFE price gains), but physical buyers remain cautious, as demonstrated by falling spot premiums. The pace of downstream purchasing activity will be critical for price direction, with particular attention on the upcoming May 31st Manufacturing PMI release for signals of potential demand improvement.
