Tom Lee Sees Ethereum Under Pressure As Kospi Falls

Tom Lee, one of Ethereum’s most well-known advocates, foresees a difficult short-term period for ETH. His warning does not question his long-term bullish thesis: it concerns a possible contagion effect coming from the South Korean stock market.

The Kospi slump threatens to spread to cryptos

The Kospi index fell more than 6% during trading on October 13, under pressure from technology stocks and semiconductor manufacturers. Samsung Electronics and SK Hynix recorded losses close to or exceeding 8%.

The extent of the movement pushed Korea Exchange to activate a “sidecar” seller. This mechanism temporarily suspends certain automated orders when futures experience excessive variation. The Kospi 200 futures had then lost more than 5%.

Tom Lee fears that these stock market losses will transmit to the crypto market. He wrote on X :

This significant drop in Korean stocks is likely spreading to cryptocurrencies.

The Fundstrat co-founder identifies two risk factors: margin liquidations in South Korean brokerage firms and the strong participation of the country’s investors in the digital asset market.

His message ends with an explicit warning regarding Ethereum: “short-term pain for ETH”. Lee however did not announce a precise bearish target nor a duration for this possible correction.

Margin calls can force ETH sales

Many investors buy stocks with money borrowed from their broker. When the value of their portfolio drops, they must provide additional collateral or reduce their debt.

If they don’t have immediate liquidity, they may sell other assets, including bitcoins or ethers. The Kospi decline could thus create pressure on Ethereum even if no network-specific event justifies this drop.

Brokers can also automatically sell margin-funded positions when collateral becomes insufficient. This mechanism then transforms a local stock market correction into an urgent cash need.

Tom Lee has however provided no data demonstrating that Korean investors are already massively selling their ETH to meet margin calls. His scenario describes a plausible contagion channel, but not yet quantified.

Ethereum touched an intraday low near 2411 dollars before recovering around 2515 dollars. The asset remains down about 6% over a week and trades near a technical level watched between 2500 and 2550 dollars.

Ethereum already accumulates several signs of weakness

Pressure from Korea comes in a less favorable context for ETH. The ETH/BTC ratio, which measures Ethereum’s performance against bitcoin, has fallen about 4.7% in a week to near 0.030.

This trend shows bitcoin resists better than ether during uncertainty. It contradicts, at least short-term, Lee’s hypothesis of an imminent Ethereum catch-up.

US spot Ethereum ETFs also recorded several sessions of net outflows. The weakness of these flows reduces an important institutional support just as investors seek to lower their exposure to risky assets.

A liquidity indicator followed on Binance has also fallen to its lowest level in nearly seven months. Such a drop does not automatically mean sellers dominate. It can also reflect a withdrawal of ETH to private wallets, thus reducing immediately available supply.

These signals describe a fragile market but do not prove that a new lasting downtrend has started.

Tom Lee maintains his long-term bullish conviction

The warning is surprising because Tom Lee chairs BitMine Immersion Technologies, the largest treasury company dedicated to Ethereum. The group purchased 12,532 additional ETH during the week ended October 11.

BitMine now holds 6,028,946 ETH, about 4.9% of the estimated total supply of 122.1 million tokens. This reserve is worth over 15 billion dollars at the current price.

However, the buying pace has slowed as the company approaches its target of 5% of the supply. BitMine would have only about 77,000 ETH left before reaching that threshold.

Lee continues to support Ethereum through the development of tokenization, stablecoins, and artificial intelligence agents. He believes these uses could end several years of underperformance against bitcoin.

His October 13 warning remains tactical. He anticipates forced sales related to the Korean stock market crisis without abandoning his long-term growth scenario. The strength of 2500 dollars and the Kospi’s evolution will determine if this “pain” remains temporary.
