환율 1,350원대 추락, 달러 살때인가, 팔때인가? (박종훈의 지식한방)

Finance-focused summary (exchange rate & USD investing framework)

Exchange rate context & key figures

• USD/KRW fell from ~1,560 to ~1,350, a drop of ~13%.
• Historical reference points mentioned:
  • 2018: ~1,054 KRW/USD (speaker’s “principle” origin)
  • ~3-year average threshold: ~1,403 KRW/USD (36-month average cited)
  • Sept 4 close: 1,350 KRW/USD, described as having “entered the action line”
• The speaker argues you shouldn’t rely on short-term daily FX moves, because FX speculation is difficult even for experts.

Core investment philosophy: why buy USD (not FX gambling)

• Warning against currency speculation: Buying/selling based on the near-term FX direction is portrayed as extremely risky; even central banks struggle to forecast consistently.
• USD as a “ticket” to compound growth:
  • USD exposure is framed as gaining access to global/US assets that may appreciate faster.
  • The goal is compounding, not quick spreads from trading FX.
• Won risk & diversification rationale:
  • Many domestic expenses/assets are KRW-denominated.
  • If KRW weakens, the real value of those USD holdings (in local terms) can change—so the speaker treats USD as currency diversification rather than a simple one-way bet on KRW appreciation.
• No “all-in” mindset: Emphasis on diversification and risk management, not concentrating entirely in one asset/currency.

Methodology / step-by-step framework (“3-year average” + splitting)

The speaker describes a rules-based KRW→USD conversion approach:

• Maintain a “currency exchange principle” dating to 2018:
  • Convert KRW → USD continuously when USD/KRW falls below the average of the past ~3 years.
• Specific threshold used in the talk:
  • 36-month average: 1,403 KRW/USD
  • Since Sept 4 close: 1,350 KRW/USD, this is treated as a signal to start/continue converting.
• Execution style (“split currency exchange”):
  • Use fixed timeframes (e.g., 6/9/12 months).
  • More aggressive investors may shorten to as little as 3 months.
  • Alternatively, use automatic/regular buys when the rate falls below a chosen level.
• Behavioral caution:
  • Don’t try to “perfectly time” entries/exits.
  • “No one can sell dollars when it skyrockets and buy when it miraculously drops.”

Performance examples cited (2018 baseline)

The speaker contrasts:

1) USD-based investing into equity indices 2) Pure FX gains only

Key numbers mentioned:

• Equity indices (from 2018 context):
  • KOSPI: up ~174% by “now” (speaker timeline = ~7 years)
    • Example: ₩1,000,000 → ₩2.74M
  • Nasdaq Composite ETF (USD-based): up ~282%
    • Example: ₩1,000,000 → ₩3.82M
  • Converting into KRW terms, Nasdaq result cited as ~389%
    • Example: ₩1,000,000 → ₩4.89M
• Pure FX-only trading return:
  • USD/KRW move from 1,054 → 1,350 yields about ~28% over ~7 years
  • Presented as only slightly above bank interest.

Risk management: volatility & “safe assets” during crises

• Equity drawdown frequency:
  • Crisis roughly every 8–12 years
  • Nasdaq typical drop: ~50–60%
  • Extreme example cited: Nasdaq down from 5,100 to 1,100 (~-78%) in 2000
• Suggested “safe assets” to balance equity risk:
  • US short-term bonds
  • Gold
• Important caution about FX–equity relationships:
  • USD asset values may not always rise during crises.
  • In severe US crises, the dollar could be “corrupt/lose credibility,” and KRW can weaken even faster.
  • Also noted: USD assets may be less volatile than Korean equities.

Korea-specific volatility & leverage (portfolio/risk angle)

• Higher Korean market volatility is attributed to leveraged products:
  • Leveraged trading volume share:
    • Initially around 30% of common-stock trading volume after leverage launch
    • In July: up to ~51%
  • Including leveraged products:
    • ~83% of July trading volume concentrated in Samsung Electronics + SK Hynix
• Company volatility example (HBM semiconductors):
  • Peak-to-late drop (as of “last Friday” in subtitle):
    • Micron: -16%
    • SK Hynix: -43.6%
• Claim: Korean capital markets are more vulnerable; leverage concentration amplifies downside.

Macro/policy catalysts & FX “overshoot/undershoot” logic

• Possible policy response (as FX moves too far):
  • Bank of Korea may raise rates if FX stays high.
  • Government actions may address supply/demand imbalances.
• “Undershooting” example:
  • When export-linked players (Samsung/Hynix) sell/convert large USD to KRW, market participants may extrapolate further KRW strengthening.
  • This can cause large KRW bids and FX to fall below equilibrium.
• Behavioral mechanism:
  • FX can show overshoot and undershoot due to psychology and momentum.

Long-term USD/KRW trend arguments (and Japan comparison)

• Japan comparison used to argue resilience:
  • Yen example:
    • Rise: 75 yen (month) in 2011 → 156 yen (more than double; “value cut in half”)
    • Another period: 120 yen (2014) → 100 yen (2019) (-17%)
  • Japan drivers attributed to:
    • Fiscal deficits → bond issuance → potential monetary financing (BOJ “printing”)
    • Demographics (aging; fewer productive consumers)
• Speaker’s conclusion:
  • Even if FX depreciates, holding USD-linked US equities may still outperform because US asset growth and higher US rates can dominate.
• USD/KRW long-term trend figures cited:
  • 2018 annual average: ~1,099
  • 2025 annual average: ~1,421 (increase ~+29%)
  • 2010s 10-year average: ~1,130
  • 2020s 10-year average: ~1,285

Forward-looking “timing variable” (explicit macro signal)

The speaker emphasizes a macro condition:

• Whether US 10-year Treasury yield breaks through 5%.
  • If it rises to ≥5%, it may significantly affect valuation/investment conditions and thus KRW/USD dynamics.
• Also notes concentration sensitivity:
  • Korea’s macro variables are portrayed as highly dependent on Samsung Electronics and SK Hynix.

Disclosures / disclaimers

• No explicit “not financial advice” phrasing appears in the subtitles provided.
• However, the speaker frames the approach as a principle/framework and repeatedly cautions against “speculating” on short-term FX direction.
