美聯儲哈瑪克：如果公衆理解美聯儲的方向，可以限制市場波動，避免錯誤。

Oil prices fell slightly on Tuesday as markets balanced supply risk from an attack on Saudi Arabia against the prospect of added Russian diesel exports. President Trump said Russia had agreed to supply diesel to global markets and that his administration would temporarily lift sanctions on Russian fuel; US bipartisan lawmakers said the deal appears to violate a US law banning imports of Russian energy until the Russia‑Ukraine conflict ends. KCM Trade chief analyst Tim Waterer said increased Russian diesel flows and steady Saudi pipeline deliveries have eased some supply pressure, but markets remain concerned about the risk of further attacks on Gulf vessels or pipelines.
