No One Talks About This

The South Korean stock market is at risk due to a leverage bomb worth $40 billion. Despite a 177% increase in the KOSPI, it heavily depends on U.S. high-risk assets. Rising volatility indicates potential market pressure as retail investors are connected to U.S. tech stocks.

South Korea’s stock market is a $40 billion leveraged bomb waiting to explode. The KOSPI index has risen 177% over the past year.

On the surface, it seems like a strong rally driven by Samsung, SK Hynix, and expectations for AI chip exports.
But deep down, it’s a rally heavily dependent on high-risk US assets. South Korea is one of the most retail investor-dominated markets worldwide. The same active investor group that fueled the “Kimchi Premium” phenomenon in the cryptocurrency world has now shifted to the stock market.
In 2025, South Korean retail investors allocated $40 billion into US leveraged ETFs, with $7 billion of that in December alone.
The volume of capital flowing into 2x and 3x leveraged tech ETFs abroad has become so large that regulators have imposed mandatory training requirements and trial trading to control retail investor access.
But the biggest warning sign is volatility.
Volatility is increasing while the KOSPI remains at sky-high levels. Usually, volatility spikes at market bottoms. A sudden increase in volatility at the peak indicates that investment positions have been pushed to the absolute limit through buying call options and heavy leverage.
Consider the risks:

A domestic rally of 177% almost entirely driven by semiconductors
$40 billion invested in highly leveraged US tech ETFs
Rising volatility coinciding with market peaks
If the US tech market corrects or AI trading cools down, Korean retail investors will face heavy pressure on two fronts: a decline in the domestic market due to slowing chip exports, and amplified declines in the US caused by enormous leverage abroad.
Korean retail investors are now major buyers of high-beta US tech stocks. Seoul’s market health is directly linked to Nasdaq volatility.
Korean retail investors are not only leveraging their own market. By pouring $40 billion into US ETFs, they have directly connected Seoul to Nasdaq.
This level of leverage is unprecedented, and so will be the unwinding.
