## 1. Event: The Largest IPO in History and Its Shock to Emerging Economies

On June 12, 2026 (local time), SpaceX will list on the Nasdaq under ticker SPCX. The key figures are as follows[^1]:

- **Valuation**: $1.5–$1.75 trillion (approximately 2,100–2,500 trillion won) — on par with Alphabet and Amazon
- **Offering Size**: $75 billion (approximately 105 trillion won), at $135 per share
- **Underwriters**: Bank of America (retail), Goldman Sachs, JPMorgan, Morgan Stanley, UBS
- **Financial Condition**: $4.9 billion loss in 2025, $4.3 billion loss in Q1 2026 — a growth stock without profitability
- **Retail Allocation**: Up to 30% — the highest retail allocation ratio in IPO history (CNBC, 2026-04-02)
- **Subscription**: Oversubscribed

No global IPO has been larger than Saudi Aramco (2019, $1.7 trillion). However, unlike Aramco, which was mostly allocated domestically, SpaceX targets institutional and retail investors worldwide. Never before has liquidity of this magnitude been absorbed by a single stock listing in the global market.

## 2. Transmission Path to South Korea: $1.5 Billion in Demand

On June 10, 2026, Reuters reported exclusively, citing a South Korean forex market source, that **dollar demand linked to the SpaceX IPO in South Korea, estimated at approximately $1.5 billion** (about 2.3 trillion won), had passed foreign exchange authority approval and entered its final stage[^2].

The key passage: This dollar demand **"has weighed heavily on the South Korean won in recent weeks."**

Breaking down the transmission path:

```
Domestic institutions (pension funds, asset managers, securities firms) subscribe to SpaceX IPO
  → Won-to-dollar conversion ($1.5 billion)
    → Won/dollar exchange rate rises (won weakens)
      → Increased concern about FX losses among foreign equity investors
        → Foreign investors increase KOSPI selling
          → KOSPI declines
            → Credit balances/margin calls → forced retail selling → further decline
```

The figure of $1.5 billion itself is not large relative to South Korea's foreign exchange reserves ($427 billion as of May 2026) or average daily forex trading volume. However, its effect as a **directional signal** was significant. The perception that global funds were moving toward a mega US IPO accelerated foreign selling, forming a feedback loop between the exchange rate and stock prices.

## 3. KOSPI −17.2% in 7 Trading Days: The Collapse in Numbers

After hitting an all-time intraday high of 8,933.62 on June 2, the KOSPI crashed to 7,394.46 within 7 trading days[^3]:

| Date | Close | Change | Event |
|------|-------|--------|-------|
| June 2 (Mon) | 8,801.49 | +0.15% | Intraday 8,933.62 — all-time high |
| June 5 (Fri) | 8,160.59 | **−5.54%** | Broadcom AI guidance shock. Sell sidecar triggered |
| June 8 (Mon) | 7,484.41 | **−8.28%** | Intraday low 7,442.73. Circuit breaker triggered |
| June 9 (Tue) | 8,096.93 | **+8.18%** | Retail buying surge. Buy sidecar triggered |
| June 10 (Wed) | 7,730.82 | **−4.52%** | Joint foreign and institutional selling. Sell sidecar retriggered |
| June 11 (Thu) | 7,628.78 | −1.32% | Recovering after intraday low of 7,394.46 (as of 11:00 KST) |

Sell sidecars were triggered on 2 out of 3 trading days, and a circuit breaker was triggered on June 8. The explosive retail buying on June 9 drove an 8.18% rebound, but most of that gain was wiped out in a single day (June 10).

## 4. The Scale of Foreign Exodus

According to Korea Exchange data, over the month from May 8 to June 8, foreign investors net sold a total of **59.591 trillion won** in the KOSPI and KOSDAQ[^4]. Of this, **82% was concentrated in Samsung Electronics and SK Hynix** (Yonhap News, 2026-05-30). In a separate tally by Aju Business Daily (May 7–June 5), net selling in the KOSPI alone reached 69.4001 trillion won, with 57 trillion won concentrated in Samsung and SK.

Cumulative net selling from the start of the year to June 10 reached approximately 125 trillion won (Money Today, 2026-06-10). In contrast, foreign investors net bought 5.8 trillion won in the KOSDAQ over the same period, showing a selective exit pattern focused on large-cap stocks.

Retail investors absorbed most of this volume alone. Yonhap News (2026-05-30) reported that "retail investors recorded the largest-ever net buying in the KOSPI."

## 5. Simultaneity with Oil Prices and the FOMC

The SpaceX IPO is not an isolated shock. Three downward pressures are operating simultaneously:

**① Iran War / Oil Price Surge**: As of June 11, WTI stands at $92.05 (+4.37%), Brent at $94.80 (+3.66%). On June 10, escalating Middle East tensions (renewed threats to the Strait of Hormuz) triggered another oil price surge[^5]. South Korea imports all of its crude oil; an estimated $10 rise in oil prices worsens the annual current account by approximately $6 billion. The energy price surge triggered by the Iran war pushed the US May CPI to 4.2% (the highest in 3 years and 1 month)[^6].

**② FOMC Hawkish Shift**: The first FOMC meeting under new Fed Chair Kevin Warsh will be held on June 16–17 (US time June 17–18). CME FedWatch prices a 70%+ probability of at least one rate hike within the year[^7]. Forbes (June 8) reported that the "easing bias" language would be formally removed at this meeting.

**③ AI Supply Chain Doubts**: Starting with Broadcom's AI guidance miss of $1.5 billion (June 5), concerns about a peak in AI investment spread across semiconductor stocks[^8]. Oracle's after-hours plunge following its June 10 earnings amplified these fears.

All three pressures push in the direction of a weaker won. Rising oil prices raise import costs, a hawkish FOMC strengthens the dollar, and AI doubts trigger foreign selling. The SpaceX IPO adds a **fourth pressure: liquidity absorption**.

## 6. Structural Implications: The Leverage Effect

The dollars that flowed out of South Korea for the SpaceX IPO amount to only $1.5 billion. Yet in the 7 trading days during which this $1.5 billion acted as one factor, the KOSPI fell 17.2% from its peak. This reveals a **structure in which a small forex shock is amplified into a leveraged effect in the stock market:**

1. Direct demand for $1.5 billion in currency conversion → won depreciation pressure
2. Won depreciation stokes foreign investors' concerns about FX losses → approximately 60–69 trillion won in net selling over one month
3. Foreign selling lowers stock prices → credit balances and margin calls trigger forced retail selling
4. Result: The initial $1.5 billion shock, combined with multiple factors, expands into an approximately 17% index decline

Of course, the SpaceX IPO alone is not the sole cause. It is the result of multiple factors: the Broadcom shock, oil price surge, FOMC concerns, and others. However, it is difficult to deny that the directional signal provided by the SpaceX IPO — "global funds are flooding into US mega-cap growth stocks" — acted as a catalyst that accelerated foreign selling. Forbes and Bloomberg repeatedly pointed to "capital flow from emerging markets to the US" ahead of the IPO.

## 7. Who Bears the Cost

The picture revealed by trading entity data is clear. The pattern of retail investors alone absorbing the selling by foreign and institutional investors repeated throughout June:

| Entity | June Pattern | Role |
|--------|--------------|------|
| Retail | Largest-ever net buying in KOSPI | Alone absorbs all selling volume |
| Foreign | Net selling of ~60 trillion won in one month | Dollar conversion / global rebalancing |
| Institutional | Joint net selling | SpaceX subscription / FX hedging |

This recalls the 2020 'Donghak Ant' movement, but with a critical difference.

2020 was an era of global liquidity expansion. The Fed supported the market with zero interest rates and unlimited quantitative easing, and retail buying was riding the wave of liquidity. 2026 is the opposite. The Fed is pivoting to rate hikes, and the Bank of Korea has signaled a hike in July. Retail buying is akin to building sandcastles on a beach at low tide.

**Within the comprador-monopoly structure of the South Korean economy, the shock of the global financial order is repeatedly absorbed by retail investors — the savings of wage workers, the self-employed, and retirees.** This is not merely a matter of 'investment losses,' but a question of who structurally bears the impact of global capital movements.

## 8. Outlook: The Watershed of June 12–18

After the SpaceX listing date of June 12, dollar demand is likely to peak and then ease in the short term. The Reuters source also described it as being in its "final stage."

However, the bigger variable is the FOMC on June 17–18 (US time). If Chair Warsh's dot plot suggests two or more rate hikes within the year:

- **Exchange rate**: Possible retest of 1,561 won per dollar
- **KOSPI**: 7,400 level again under threat, possible test of 7,000
- **Bank of Korea**: A rate hike at the July 16 MPC becomes unavoidable, but the debate over the size — 'big step' (50bp) vs. 'baby step' (25bp) — intensifies
- **Household debt**: In the era of 2,000 trillion won in household debt, the path through which rising interest rates dramatically increase household interest burdens becomes linked

Conversely, if the FOMC turns out more dovish than expected, combined with the easing of the SpaceX IPO shock, a retest of 8,000 on the KOSPI is also possible. However, current market pricing leans toward the hawkish scenario.
