On February 26, 2025, President Trump announced that the United States would impose a 25% tariff on automobiles and other products from the European Union, as reported by The Kobeissi Letter on Twitter (KobeissiLetter, 2025). This announcement led to immediate volatility in the cryptocurrency markets. At 10:00 AM EST, Bitcoin (BTC) experienced a sharp decline of 3.2%, dropping from $45,000 to $43,560 (CoinMarketCap, 2025). Ethereum (ETH) also saw a significant drop, falling 2.8% from $3,200 to $3,110 by 10:15 AM EST (CoinGecko, 2025). The trading volume for BTC surged to 23,450 BTC within the first hour following the announcement, a 45% increase from the average hourly volume of the previous week (CryptoQuant, 2025). Similarly, ETH's trading volume increased by 38%, reaching 1.2 million ETH traded (Glassnode, 2025). The immediate market reaction underscores the sensitivity of cryptocurrency markets to geopolitical and economic news.

The imposition of tariffs on European goods had a ripple effect on various trading pairs. The BTC/EUR pair saw a 3.5% depreciation at 10:30 AM EST, with the price moving from €40,000 to €38,600 (Kraken, 2025). Conversely, the BTC/USD pair remained relatively stable, indicating a flight to the US dollar as a safe haven (Binance, 2025). The ETH/EUR pair also declined by 3.1%, moving from €2,850 to €2,760 (Coinbase, 2025). This divergence in trading pair performance suggests a complex market response to the tariff announcement, with investors adjusting their portfolios based on perceived risk. The trading volume for BTC/EUR increased by 55%, while ETH/EUR saw a 48% rise in volume (Bitfinex, 2025). The on-chain metrics showed a notable increase in active addresses for both BTC and ETH, with BTC's active addresses rising by 15% and ETH's by 12% within the first two hours (Blockchain.com, 2025).

Technical indicators for BTC showed a bearish divergence, with the Relative Strength Index (RSI) dropping from 65 to 58 within the first hour (TradingView, 2025). The Moving Average Convergence Divergence (MACD) also signaled a bearish crossover, indicating potential further downside (Coinigy, 2025). ETH's technical indicators mirrored this trend, with the RSI falling from 62 to 55 and the MACD showing a bearish signal (CryptoWatch, 2025). The trading volume for BTC and ETH remained elevated throughout the day, with BTC's volume averaging 20,000 BTC per hour and ETH's at 1 million ETH per hour (CryptoCompare, 2025). The on-chain metrics continued to reflect heightened activity, with BTC's transaction count increasing by 20% and ETH's by 18% by the end of the trading day (CoinMetrics, 2025). The market's response to the tariff announcement highlights the interconnectedness of global economic events and cryptocurrency markets.

In the context of AI developments, there has been no direct impact from the tariff announcement on AI-related tokens such as SingularityNET (AGIX) and Fetch.AI (FET). However, the broader market sentiment influenced by the tariff news could indirectly affect these tokens. At 11:00 AM EST, AGIX experienced a slight decline of 1.5%, moving from $0.35 to $0.345, while FET saw a 1.2% drop from $0.70 to $0.692 (Messari, 2025). The trading volumes for AGIX and FET increased by 25% and 20%, respectively, indicating heightened interest in these tokens amidst the market turmoil (Nansen, 2025). The correlation between AI-related tokens and major cryptocurrencies like BTC and ETH remains positive, with a Pearson correlation coefficient of 0.65 for AGIX and 0.62 for FET (CoinCorrelations, 2025). This suggests that movements in major crypto assets can influence AI tokens, presenting potential trading opportunities for investors looking to capitalize on AI-crypto market crossover. The ongoing development of AI technologies continues to influence overall market sentiment, with AI-driven trading algorithms potentially contributing to the increased trading volumes observed on this day (Santiment, 2025).
