[DigitalToday reporter Yoonseo Lee (이윤서)] U.S. President Donald Trump's tariff policy and crypto-related remarks are increasing market volatility. After the Supreme Court ruled some tariff increases unconstitutional, Trump announced additional tariffs and the cryptocurrency market wobbled again.

Foreign media including blockchain outlet Cointelegraph reported on Feb. 27 (local time) that Trump's tariff policy has repeatedly put downward pressure on the cryptocurrency market since it was first introduced in April 2025. As tariffs raised global economic uncertainty and stoked risk-off sentiment, bitcoin and other major coins weakened in tandem.

Trump's moves do not always trigger declines. When he delivers messages friendly to cryptocurrencies or rolls out pro-crypto policies, the market has sometimes reacted immediately with short-term rebounds.

Ahead of Trump's inauguration, World Liberty Financial (WLFI), a cryptocurrency project run by his family, bought multiple tokens including bitcoin, ether, tron and chainlink. Bitcoin then rose 4.5 percent over 24 hours. After the inauguration, an executive order was announced that blocked the possibility of a U.S. central bank digital currency (CBDC) and launched a working group with the character of a "digital asset market task force". Bitcoin rose 1.34 percent in a day.

Still, pro-crypto moves have not translated directly into gains. When the public sale of the WLFI token ended, bitcoin fell 1.59 percent in a day, underscoring mixed reactions. Bitcoin also slipped 0.1 percent over 24 hours when Trump continued remarks backing the crypto industry at the Blockworks Digital Asset Summit, with large swings limited.

Tariff issues, by contrast, often had a more direct impact. When Trump announced broad tariff increases, bitcoin fell 5.7 percent in the short term, but later recovered to a 2.14 percent gain over a week as bargain hunting and a reassessment of macro risks combined. After the Supreme Court ruling, Trump announced additional tariffs, putting renewed downward pressure on the market, and bitcoin extended its weakening trend.

Trump's remarks are increasingly shaping prices less on their own than through policies that expand into macro factors such as tariffs. The analysis is that as cryptocurrencies become more connected to traditional finance, macro uncertainty over trade, inflation and the economy could play a larger role in driving prices than short-term positive factors such as "pro-crypto remarks".
