Bank of Korea’s rate hike triggers a global storage stock pullback: Is the AI bull market about to end?

July 16 saw an unexpected jolt across the capital markets.

The storage-chip sector, which was originally still immersed in an AI frenzy, suddenly suffered a broad-based plunge. In the U.S. stock market, SK hynix ADR fell by more than 9%, Micron (Micron) dropped nearly 10%, and Intel also weakened in tandem; meanwhile, after the opening of the South Korean market, the losses widened further. SK hynix once fell by more than 11%, Samsung Electronics dropped nearly 8%, the Korea Composite Index (KOSPI) was down more than 6% intraday, and even the Korean exchange activated a temporary trading halt mechanism.

At the same time, the Bank of Korea announced it would raise the benchmark interest rate by 25 basis points to 2.75%. This was the first rate hike since 2023, and it also became an important fuse for further intensifying market panic.

Many people’s first reaction was:

Is the AI bubble starting to crack?

But if you break down this event in detail, you’ll find it’s not that simple.

⸻

Why did storage stocks suddenly plunge?

This drop is, in essence, the simultaneous resonance of several factors.

First, expectations were too high.

Over the past year, AI has practically propped up the entire semiconductor industry.

Whether it’s NVIDIA, SK hynix, Micron, or Samsung, as long as it is related to HBM (high-bandwidth memory), DRAM, or AI servers, valuations have kept climbing.

Especially SK hynix.

With supply advantages in HBM3 and HBM3E, it has become one of the companies most benefiting from AI.

Since the start of this year, the stock price has already risen cumulatively by dozens of percentage points.

When everyone believes that “demand in the coming years will only keep getting higher,” the market has actually priced in years of growth in advance into the stock price.

That means—

Any bit of negative news can become a reason for profit-taking liquidation.

⸻

Second, the Bank of Korea suddenly raised rates.

For growth stocks, rate hikes are never good news.

Because:

* borrowing costs for enterprises increase;

* market liquidity tightens;

* discount rates for overvalued assets rise;

* risk appetite declines.

Especially since South Korea has the world’s largest storage industry.

Samsung Electronics and SK hynix almost determine global DRAM and HBM supply.

Therefore, changes in South Korea’s monetary policy can easily affect global capital’s valuation judgments for the entire storage industry.

Although a single 25BP hike won’t directly change corporate earnings,

it is enough to affect short-term sentiment.

⸻

Third, institutions start to worry that AI demand growth may slow.

What truly makes the market tense isn’t the rate hike itself.

Rather, it’s that some institutions have begun discussing a question:

Can AI servers still maintain the kind of explosive procurement from the past?

According to multiple recent viewpoints from institutions:

* some cloud providers’ capital expenditures are becoming more rational;

* the supply-demand imbalance for HBM remains;

* but the pace of DRAM price increases may start to slow;

* NAND is gradually replacing some traditional DRAM applications.

In other words,

future growth still exists,

but the growth rate may not be as dramatically high as the market imagines.

For stocks that have already risen a lot,

“not continuing to beat expectations” is, by itself, a negative.

⸻

Has the AI industry chain truly reached its peak?

At present, it’s still too early to make that conclusion.

The reason is simple.

The core logic that drives the AI industry hasn’t changed.

Global cloud computing companies are still continuously building AI data centers;

NVIDIA’s next-generation GPUs still require large amounts of HBM;

companies like Microsoft, Meta, Google, and OpenAI continue to maintain high levels of AI investment.

That means,

demand hasn’t disappeared.

What’s really changing is:

the market is starting to reassess valuations.

Over the past year,

many stocks’ gains came more from “expectations,”

while the future will require “earnings delivery” more.

The capital market is moving from “telling stories” to “watching profits.”

⸻

Will this affect the crypto market?

Many Crypto investors might think:

If chips fall, what does it have to do with the crypto world?

Actually, the connection is not small.

Over the past year, the performance of U.S. AI and technology stocks has been highly correlated with BTC.

The reason is simple:

global risk capital is flowing in the same direction.

When AI is strong and tech stocks rise, BTC often also finds it easier to rise.

And when the market starts lowering risk appetite,

capital may withdraw in parallel from overvalued tech stocks and highly volatile assets.

However, for now,

this looks more like a short-term repricing of risk assets.

If it’s only a Bank of Korea rate hike and adjustments in the storage sector,

it’s not enough to change the broader global liquidity trend.

What truly determines the next phase of Crypto’s market action is still:

* the subsequent pace of rate cuts by the Federal Reserve;

* U.S. inflation data;

* whether ETF inflows continue steadily;

* whether global liquidity keeps improving.

So,

what’s worth focusing on in this episode is market sentiment, not panic itself.

⸻

Written at the end

Capital markets never keep rising forever.

Especially when everyone believes a particular sector is “sure profit with no downside,” volatility often starts to amplify.

The Bank of Korea’s rate hike only ignited the profit-taking sentiment that had already been accumulating in the market; a sharp drop in storage stocks doesn’t necessarily mean the AI industry has entered a downturn cycle.

What really needs watching isn’t the drop in a single day, but whether enterprise orders, profits, and AI infrastructure investment remain strong over the coming quarters.

For investors, this pullback is more like a stress test: if fundamentals haven’t changed, then the turbulence is just an episode within a bull market; if demand continues to fall below expectations, the market may enter a new phase shifting from “valuation-driven” to “earnings-driven.”

A true bull market has never been a straight line up; instead, after every bout of sharp volatility, it still manages to make new highs.
