According to ChainCatcher, former U.S. Treasury Secretary Yellen stated on Monday that Trump's tariff policies are "unclear and not wise at all".

Yellen noted that recent bond market volatility and dollar weakness reflect a "loss of confidence," though the situation has not yet reached a point requiring Federal Reserve intervention. She stated: "Measures to cancel and reduce tariffs are positive, but we are in a world full of great uncertainty." She expressed confusion about some of the tariff measures' objectives. Yellen said: "If genuine financial stability concerns arise, I believe the Federal Reserve would consider using liquidity tools as they did when the pandemic began." "But we are not at that point yet."
