Bitcoin falls below $108k on US-China trade worries

Bitcoin dropped below US$108,000 on October 21 as traders reacted to ongoing US-China trade tensions and broader macroeconomic uncertainty.

The cryptocurrency fell 2.6% to US$107,900 in the past 24 hours, after briefly rebounding above US$111,200 on October 20.

Other major tokens also saw drops, with ether down 4.8% to US$3,900, BNB falling 5.4%, and Solana losing 4.3%.

An analyst said volatility may persist due to uncertainty around an upcoming meeting between US President Trump and Chinese leader Xi Jinping in South Korea at the end of October.

Spot bitcoin ETFs recorded US$40.5 million in net outflows on October 20, while spot ether ETFs saw outflows of US$145.7 million, after a week of US$1.2 billion in net outflows from BTC ETFs.

🧠 Food for thought

Implications, context, and why it matters.

Bitcoin swings amid trade tensions with no proven causal link

  • A news article ties Bitcoin’s slide below $108,000 to U.S.-China tensions, yet the evidence is thin. USD/CNH hit 7.4273 in April 2025 1 and has fallen about 2.5% this year while Bloomberg Dollar Spot Index dropped nearly 8% 1.
  • BTC futures open interest reached $91.59 billion by October 5, 2025, and spot BTC ETFs took in $3.24 billion in week ending October 4 2.
  • No 2025 correlation work ties BTC to USD/CNH or China-linked risk proxies (assets that typically react to China-related headlines) 2. Blaming swings on trade ignores other forces such as derivatives positioning and regulatory moves.

Volatility creates demand for hedging products that brokerages and fintechs can capture

  • Wealth platforms plus crypto brokers can package volatility-targeting with options income strategies. Options tied to BlackRock’s iShares Bitcoin Trust (IBIT) hit $38 billion in open interest, above Deribit’s $32 billion 3.
  • Near-year-end 2025 BTC options cluster around the $140,000 strike 4. Deribit options open interest stands at $42.5 billion with heavy positioning near $110,000, $120,000, and $300,000 2. Setup supports demand for structured products that manage downside while expressing views.
  • Data vendors plus trading platforms stand out by mapping options volume and implied volatility across venues, with IBIT at 45% of BTC options open interest versus Deribit at 41.9% 5. Ties with CME Group (CME), a U.S. derivatives exchange that plans 24/7 crypto trading in early 2026 2, can channel hedging flows as the market matures.
