After the release of the US August CPI data, market pricing for a rate hike swiftly climbed to nearly 90%. Just this past weekend, several international investment banks, including Goldman Sachs and Citigroup, simultaneously revised their policy forecasts, abandoning their earlier stance of holding rates steady and now broadly anticipating a 25-basis-point increase at next week's FOMC meeting. If the Federal Reserve does proceed with a hike, how would markets react, and which sectors would be impacted? This analysis delves into these questions.

To understand sector rotation, one must first clarify the liquidity transmission mechanism, as all industry trends evolve within this framework. First, a rise in the global risk-free rate triggers a repricing of asset valuations. US Treasury yields serve as the pricing anchor for global equity assets. A rate hike pushes these yields higher, raising the discount rate in DCF valuation models and compressing the present value of future cash flows. Growth assets with long durations, high valuations, and earnings concentrated in the future face the most significant valuation pressure, while value assets with stable cash flows and near-term earnings certainty are relatively less impacted.

Second, a stronger US dollar puts intermittent pressure on the RMB exchange rate. Rate hikes enhance the appeal of dollar-denominated assets, boosting the dollar index and creating potential pressure on the RMB. However, it is crucial to note that the RMB has generally appreciated against the dollar since 2026, supported by domestic economic fundamentals, export resilience, and pressure on dollar credit. The exchange rate transmission is not a simple unidirectional relationship: the actual trend since 2026 shows the RMB appreciating overall, with export enterprises generally absorbing exchange losses while import-dependent firms benefit from lower costs. Sector-specific impacts require careful analysis of individual business structures and the actual currency direction.

Third, widening global interest rate differentials increase volatility in northbound capital flows. Rising US Treasury yields widen global spreads, enhancing returns on US bonds and dollar deposits, which drives global capital back to the US. Northbound capital flows into A-shares may see periodic reductions and rebalancing, causing short-term disruptions to market sentiment and foreign-heavyweight holdings.

Fourth, higher global financing costs gradually weaken external demand expectations. Sustained high interest rates raise borrowing costs for households and businesses worldwide, suppressing US consumption and corporate capital expenditure. This poses a downside risk to overseas aggregate demand, potentially disrupting the medium-term prospects of manufacturing sectors heavily reliant on foreign orders.

Fifth, the global inflation landscape is being reshaped. While the intent of rate hikes is to curb inflation, current energy supply constraints and geopolitical conflicts continue to disturb commodity prices, creating a contradictory situation of policy tightening coupled with supply restrictions. This complicates the fundamental logic for energy and resource cyclical sectors.

These five transmission channels operate concurrently, with many internal logic streams within industries offsetting one another. Some manufacturers benefit from export exchange conversions while simultaneously relying heavily on imported raw materials, making it impossible to apply simple labels; a case-by-case assessment based on each enterprise's specific business structure is essential.

Should the Fed follow through with a hike, certain sectors may benefit. High-dividend financials: A marginal rise in long-end rates initially benefits insurance companies, which hold a significant proportion of fixed-income assets. As market yields increase, returns on newly allocated bond investments improve, directly enhancing the investment returns on insurers' asset sides and alleviating the interest spread pressure that has persisted from years of declining fixed-income yields. For insurers with robust liability-side operations, these improvements can be directly reflected in profit statements. For banks, the core driving force behind a recovery in net interest margins comes entirely from domestic factors, including the repricing of maturing high-cost time deposits, reduced liability costs from declining deposit listing rates, and a pick-up in credit disbursement. The external hiking environment merely limits the scope for further domestic rate cuts, serving as a marginal easing of constraints rather than a source of margin improvement. During periods of liquidity tightening and declining market risk appetite, capital naturally gravitates toward assets with certainty. High-dividend, low-volatility, low-valuation financial stocks offer strong defensive attributes and are preferred as core holdings. This theme relies primarily on valuation recovery combined with stable dividends; short-term price elasticity may be modest, but resilience against risk is significantly stronger during turbulent and corrective phases.

High overseas revenue export manufacturing chains: The pricing core for export chains has always been overseas demand dynamics, not exchange rate fluctuations. Since the RMB has appreciated overall in 2026, export enterprises have generally faced exchange losses rather than gains, making currency factors a drag on profits. However, stripping out this one-off effect, some export-oriented firms are still improving their main operations, with rising gross margins and core profits. This indicates that genuine prosperity is reflected in overseas sales volumes and product competitiveness, not in exchange rates. Only when the RMB enters a period of staged depreciation would exchange rates become a positive variable again. Therefore, stock selection should prioritize leaders with balanced overseas layouts, no over-reliance on the North American market, and high raw material self-sufficiency, while avoiding low-end OEMs that rely solely on exchange rate advantages. The sustainability of this trend depends on verification from overseas order data; if the market begins to price in weakening external demand expectations, sector momentum may be realized prematurely.

High-dividend energy and resources: With global inflation resilience persisting and geopolitical factors creating disturbances, energy prices are expected to remain in a high-level range-bound pattern. Coal and oil & gas enterprises boast strong cash flows, stable dividend mechanisms, and physical asset backing, combining both inflation-hedging and high-dividend characteristics. When market style shifts from chasing long-term growth expectations to valuing current stable cash flows, these cyclical assets are likely to attract capital interest. For coal chemical enterprises, sustained high international oil prices provide an additional tailwind, as coal-to-olefin processes gain cost advantages over oil-based chemical methods, further enhancing profitability for integrated firms. In terms of allocation, this sector's returns are supported by both commodity prices and stable dividends, giving it quasi-fixed-income defensive attributes. However, risks are clear: if the US economy enters a significant recession driving down commodity demand, falling energy prices would directly suppress earnings expectations.

Essential domestic demand sectors: Food and basic consumer goods, along with essential medicines, exhibit inherently weak cyclicality in demand and remain largely unaffected by overseas rate policies. Specialty APIs leverage global supply advantages, while branded traditional Chinese medicine is deeply rooted in domestic demand, providing strong industry independence. When external liquidity shocks cause broad market volatility, these essential demand sectors experience smaller profit fluctuations, naturally offering hedge value in portfolios. However, these sectors are better suited as volatility dampeners rather than generators of sustained trend rallies; they are more appropriate as defensive allocations in balanced portfolios.

Conversely, if the Fed hikes, certain sectors would likely face headwinds. High-valuation, long-duration growth sectors: These sectors concentrate substantial earnings realization in the coming years, making them typical long-duration assets. Rising US Treasury yields elevate global discount rates, exerting downward pressure on valuation centers even without substantive changes to industry fundamentals. Simultaneously, tech growth names are usually key holdings for northbound capital; amid widening China-US spreads, foreign rebalancing can amplify sector volatility. Higher global financing costs also marginally contract overseas tech companies' capital expenditure intentions, suppressing forward order expectations for upstream computing power and semiconductor equipment. What deserves more attention is that the market's pricing focus for tech growth sectors is shifting from “future narratives” to “earnings realization.” Even without external rate shocks, high-valuation stocks lacking earnings support face valuation normalization pressure. Consequently, adjustments in growth stocks are not solely driven by rate hikes; the sector's own valuation logic transition is equally important. This could lead to significant internal divergence: leading companies with consistent earnings delivery and valuations returning to reasonable ranges may see relatively contained corrections, while smaller targets relying solely on future narratives, lacking earnings support and carrying high valuations, face more substantial adjustment pressure. During liquidity tightening phases, growth stocks broadly enter a de-rating stage; to stage an independent rally, they would require exceptionally strong earnings growth to offset valuation headwinds. Short-term investors should avoid purely speculative themes, as a systematic valuation recovery window is likely to wait for a clear inflection point in US Treasury yields.

High-dollar-debt sectors: The aviation industry carries substantial dollar-denominated debt, with aircraft leases and supplies settled in dollars. If the dollar strengthens and the RMB experiences staged depreciation, enterprises would need more RMB to service foreign debt, generating significant exchange losses that directly hit profits. Combined with high rates dampening global travel demand expectations, the industry faces dual pressures of cost damage and weak demand. However, it must be noted that the RMB has appreciated overall in the first half of 2026, meaning the aviation industry actually benefited from exchange gains rather than losses. Therefore, the exchange rate impact on the aviation sector depends on directional RMB moves and cannot simply apply traditional frameworks. Beyond aviation, enterprises relying on offshore bond financing face higher overseas financing costs, increased refinancing difficulty, and rising financial expenses. Overall, if a rate hike drives a staged dollar strengthening and RMB pullback, industry fundamentals and expectations would face pressure, making it difficult to reverse a weak stock price trend; if the RMB remains strong, exchange rate impacts on aviation are limited, and sector trends depend more on domestic travel demand and oil prices.

Industries heavily reliant on imported raw materials: The papermaking industry's wood pulp and the aquaculture sector's soybean meal and corn have high foreign dependency. If the RMB undergoes staged depreciation, the RMB-denominated costs of imported raw materials would rise. If firms cannot adequately pass on price increases downstream, gross margins would face continuous compression. Unlike export-oriented manufacturers, these industries lack exchange gains to offset cost pressures, making sustained profit erosion likely.

Precious metals, gold: Gold is a non-yielding asset; during periods of rising real interest rates, the opportunity cost of holding gold increases. Around the implementation of a rate hike, gold prices and gold stocks typically face short-term pressure. However, this alone does not justify a one-sided bearish view on gold. The pricing logic for gold is undergoing structural changes: beyond real rates, medium-to-long-term factors such as US fiscal credibility, geopolitical conflicts, and global central bank reserve diversification are increasingly supporting gold prices. Since 2026, gold has shown resilience even with high real interest rates, indicating that the traditional unidirectional logic of “rate hikes lead to gold price declines” is weakening.

It is necessary to address the three major misconceptions currently prevalent in the market. Misconception one: A Fed rate hike guarantees sustained rallies in export sectors. Exchange-related gains are one-off profit boosts; the long-term core issue remains overseas demand. If the US economy decelerates, order declines would fully offset exchange rate benefits, and the trend could reverse rapidly. One cannot rely solely on exchange rate logic for long-term bullishness on export chains. Furthermore, given the RMB's overall appreciation in 2026, export chains have actually absorbed exchange losses in the first half, making foreign exchange factors a non-event or even adverse currently.

Misconception two: Domestic monetary policy will follow the Fed's tightening, leading to a full-blown bear market in A-shares. China and the US are at entirely different points in their economic cycles. Domestic policy priorities center on stabilizing domestic demand recovery, with monetary policy anchored to domestic fundamentals rather than passively following overseas hikes. A Fed hike only reshapes market style and fosters structural divergence; domestically driven sectors still have a foundation for independent trends.

Misconception three: The rate hike's implementation marks the end of negative news. What the market prices is not just whether rates rise, but the medium-term rate path signaled by the dot plot and Federal Reserve Chair Warsh's comments. If the meeting signals a sustained hawkish stance with further hikes, the market would reprice prolonged high rates, extending the adjustment period. Only if there is an explicit hint that this could be the last hike of the cycle could a staged recovery emerge after the event is realized.
