关于韩国综合指数(KOSPI) | $EWY (SK海力士 / 三星) 的情绪，原油 / 液化天然气(LNG) / 氦气要么：扰乱供应或压缩利润的说法被夸大了。对SK海力士、三星的供应链中断和能源成本威胁是耸人听闻的噪音。原因如下： 1. 原油：如果油价上涨31%并浮动至120美元/桶的可能情景：在这种情况下，油价对SK海力士和韩国内存股几乎没有实质性影响。通过挂钩油价的LNG/JKM价格，韩国股票面临能源成本上升，主要影响那些仅靠5%到10%微薄利润生存的公司。然而，鉴于内存价格飙升且三星在Q2将NAND价格翻倍，韩国电力公社(KEPCO) 70%的费率上调对三星/SK海力士几乎没有实质性影响。根据披露的财务数据，SK海力士的年度电费超过1万亿韩元（DIGITIMES报道，约7.5亿美元）。相对于FY2025年97.15万亿韩元的收入，这约占收入的1-2%。 SK海力士在2025年Q4实现了58%的营业利润率。在此背景下，能源成本冲击很小：如果我们模拟能源成本增加50%： - 对SK海力士季度营业利润(19.17万亿韩元)的影响：~1340亿-~1460亿韩元 (0.76%) - 对三星DS季度营业利润(16.4万亿韩元)的影响：~4070亿韩元 (2.4%) 每次50%的能源成本激增会使SK海力士的利润率减少约0.7%，三星的营业利润率减少2.4%。分析师预测SK海力士在2026年传统DRAM上的利润率可能达到70%以上。即使能源成本增加100%，也不会对韩国半导体营业利润率构成实质性威胁。然而，这对营业利润率为5-10%的低利润率公司是实质性的。输家：传统重工业（钢铁、基础化学品、普通平板玻璃）。赢家：三星/SK海力士。主要风险是供应链的二阶效应，如原材料成本增加。这很难建模，但在一个例子中：一家工业公司迫使原材料（化学品、特种气体）价格上涨30%，这对晶圆厂的影响微乎其微。材料约占半导体销售成本(COGS)的15-20%，因此从数学上讲，材料成本激增30%只会使SK海力士的营业利润率再减少约2%。一个打印70%利润率（并提高价格）的寡头可以轻松吸收3-4%的直接（公用事业）和间接（材料）能源逆风。在大多数情况下，成本可能会通过NAND/DRAM价格上涨转嫁给超大规模云服务商(hyperscalers)。在油价上涨3倍或5倍的极端情况下。油价上涨数百倍的主要影响是两个因素： - 全球宏观经济冲击，导致全球通胀（影响从$GOOGL到$COST的每一家公司）。 - 韩元(KRW) USD/KRW汇率崩盘。持续高油价导致的韩元贬值是一个真实的二阶风险，但历史上韩国内存出口商受益于韩元贬值带来的收入端优势。三星/SK海力士的大部分销售以美元计价，而成本以韩元计价。因此，韩元走弱实际上有利于出口商的利润率，部分抵消了能源成本逆风。但在油价上涨5倍的极端情况下，那个末日世界里唯一的做多标的只有原油本身、像$LMT / $NOC这样的国防承包商、美国国内能源生产商和美元。这不太可能发生。财经媒体和算法可能会恐慌，但如果原油从91美元涨到120美元且KEPCO提高能源成本：数据显示这对三星 / SK海力士几乎没有影响，主要影响的是那些营业利润率微薄的玩家。 2. LNG：如果霍尔木兹海峡关闭，韩国大部分LNG进口将不受影响。媒体一直在引用霍尔木兹海峡+流向中国、印度、韩国和日本的LNG流量。但如果我们查看韩国的贸易数据，这只是其总进口的一小部分。大部分进口通过非霍尔木兹海峡路线到达，例如澳大利亚 (24.6%)、美国 (12.2%)、马来西亚、印度尼西亚 (~20%) 和俄罗斯/萨哈林 (~4.6%)。其余部分由来自尼日利亚、秘鲁、文莱、巴布亚新几内亚等次要来源填补。 2024年82%的进口是挂钩油价的长期合同，正如我们上面建模的那样，能源成本增加会使运营支出(opex)每增加50%受损1-2%，但鉴于DRAM/NAND价格上涨和营业利润率达到70%以上，这只会造成很小的缺口。即使如此，成本也会转嫁给超大规模云服务商。韩国从2022年吸取了教训并多元化了来源，LNG供应中断的影响很小。主要担忧是油价影响LNG价格上涨。 3. 氦气： SK海力士声明：“已确保多样化的供应链和充足的氦气库存”。 “因此，公司几乎不可能受到[氦气]影响。” 现实是，像$TSM到SK海力士这样的大型玩家已经多元化了供应链以应对外部事件。氦气对半导体供应链至关重要，但媒体叙事是耸人听闻的。尤其是当最大的内存公司发表强硬声明称公司[SK海力士]不可能受到影响时。 _ 但对于三星/SK海力士等韩国股票，围绕石油/LNG/氦气的恐惧看起来与现实脱节：因氦气和KEPCO费率上调而抛售SK海力士的算法是在进行错误的计算。这从根本上说是一个非供应链问题。主要威胁是石油和能源成本对全球宏观经济冲击的影响，影响从消费品到通胀的一切。 3月3日“黑色星期二”暴跌使KOSPI下跌7.2%，SK海力士单日下跌11.5%，正是以这些能源安全恐惧为主要催化剂。当然，杠杆强制平仓火上浇油。然而，基本面与价格走势之间的脱节就是交易机会。如果利润率真的受到威胁，抛售就是合理的。但，抛售在一天内摧毁的价值比几十年能源成本上涨可能造成的还要多。数学不支持恐惧的事实正是为什么韩国是买入的理由，因为市场正在因情绪而非结构性扩张的盈利能力（尽管石油/能源成本增加）而抛售。

英文原文

The sentiment around KOSPI | $EWY (SK Hynix / Samsung) on Crude Oil / LNG / Helium either: Disrupting Supply or Compressing Margins are overblown. The supply chain disruption and energy cost threats to SK Hynix, Samsung are sensationalized noise. Here's why: 1. Crude Oil: The a likely scenario if oil prices increase 31% and oil floats to $120/bbl: In this case, the effect on oil has almost no material impact on SK Hynix and South Korean memory equities. There are increased energy costs via oil-pegged LNG/JKM prices on Korean equities, mainly for companies surviving on razor-thin 5% to 10% margins. However, a KEPCO 70% rate hike has little material affect on Samsung/SK Hynix, given memory prices have soared with Samsung doubling NAND prices Q2. From disclosed financial from, their SK Hynix's annual electricity bill exceeds ₩1 trillion per DIGITIMES (~$750M). Which against FY2025 revenue of ₩97.15 trillion represents roughly 1–2% of revenue. SK Hynix posted a 58% operating margin in Q4 2025. Against this backdrop, the energy cost shock is small: If we model a 50% increase in energy costs: - Hit to SK Hynix quarterly OP (₩19.17T): ~₩134 billion-~₩146 billion (0.76%) - Hit to Samsung DS quarterly OP (₩16.4T): ~₩407 billion (2.4%) Every 50% energy cost spike would shave roughly .7% off SK Hynix margins and 2.4% off Samsung operating margins. Analysts project SK Hynix margins could reach 70%+ on conventional DRAM in 2026. Energy costs do not meaningfully threaten Korean semiconductor operating margins, even if they were to increase by 100%. However, this is material to companies with low operating margins of 5-10% The Losers: Traditional heavy manufacturing (steel, basic chemicals, standard flat glass). The Winners: Samsung/SK Hynix. The main risk is second-order effects on supply chains such as increased material costs. This is very hard to model, but in an example where: an industrial company forces 30% price hikes on raw materials (chemicals, specialty gases), it barely dents the fabs. Materials are roughly 15-20% of semiconductor COGS, so mathematically, a 30% spike in material costs only shaves an additional ~2% off SK Hynix's operating margins. A combined 3-4% direct (utilities) and indirect (materials) energy headwind is easily absorbed by an oligopoly printing 70% margins (and increasing prices). In majority of cases, the costs likely get passed down to hyperscalers through NAND/DRAM price hikes. In the very worst case scenario of oil prices increasing 3x or 5x. The main affect on oil increasing hundreds of percent are two factors: - Global macroeconomic shock, causing global inflation (affecting every single company, from $GOOGL to $COST). - KRW (South korean Won) USD/KRW exchange rate blowout. KRW depreciation from sustained high oil is a real second order risk, but historically Korean memory exporters benefit from won weakness on the revenue side. The majority of Samsung/SK Hynix sales are dollar denominated wheras costs are won denominated. So a weaker KRW is actually margin accretive for exporters, which partially offsets the energy cost headwind. But in an extreme case of oil prices hiking 5x, the only longs in that apocalyptic world are crude oil itself, defense contractors like $LMT / $NOC, domestic US energy producers, and the US Dollar. This is unlikely to happen. The financial media and algorithms will likely panic, but , if crude oil goes from $91 to $120 and KEPCO increases energy costs: The data shows there's little affect on Samsung / SK Hynix in specific, and the main impact are on players with razer-thin operating margins. 2. LNG: If the Hormuz closed, the majority of South Korea’s LNG imports would be unaffected. The media has been quoting Hormuz + LNG flows going to China, INdia, SK, and Japan. But if we look at the trade data from South Korea, that’s just a fraction of their total imports. Majority of imports arrive via Hormuz free routes, eg. Australia (24.6%), US (12.2%), Malaysia, Indonesia (~20%), and Russia/Sakhalin (~4.6%). Then the rest filled in with minor sources from Nigeria, Peru, Brunei, PNG, etc. The 82% of 2024 important were long term contracts that were oil-indexed, and as we've modeled above, increasing energy costs would hurt opex by 1-2% per 50% increase, but given DRAM/NAND price hikes and operating margins hitting 70%+, this would make a very little dent. Even if they did, costs would be passed onto hyperscalers. South Korea learned their lesson from 2022 and diversified sources, and there's little impact on LNG supply disruption. The main concern is oil impacting hiking of LNG. 3. Helium: SK Hynix statement: “Long secured diverse supply chains and sufficient inventory" of helium. "Therefore there is almost no chance that the company will be affected [by helium]. The reality is larger players like $TSM to SK Hynix have diversified their supply chains against foreign events. Helium is critical to semiconductor supply chains, but the media narrative is sensational. Especially when the largest memory company puts out an assertive statement that there’s no chance the company [SK Hynix] will be affected. _ But to South Korean equities in Samsung/SK Hynix, fears around Oil/LNG/Helium look disconnected from reality: The algorithms selling off SK Hynix because of helium and KEPCO rate hikes are acting on bad math. It is fundamentally a supply chain non-issue. The main threat is oil and energy costs on global macroeconomic shock affecting everything from consumer goods to inflation. March 3 "Black Tuesday" crash dropped KOSPI dropped 7.2% and SK Hynix fell 11.5% in a single session on exactly these energy security fears as the main catalyst. Of course, forced liquidations from leverage added fuel to the fire. However, the disconnect between fundamentals and price action is the trade. If margins were actually threatened, the selloff would be justified. But, the sell-off destroyed more value in one day than DECADES of hiked energy cost increases could have. The fact that the math doesn't support the fear is precisely why it's Korea is a buy, as markets are selling off on emotion rather than looking at the structural expanding profitability despite increasing oil/energy costs.
