The U.S. oil blockade intensifies the energy crisis, Cuba suspends its annual cigar festival

U.S. Treasury Secretary Janet Yellen defended the rise in U.S. Treasury yields, stating that this increase is a global phenomenon rather than unique to the United States, and does not warrant excessive concern. She partially attributed inflationary pressures to higher oil prices caused by the Iran conflict, and expects the energy shock to subside as hostilities ease. Yellen refuted the notion of an AI bubble, arguing that investments by major tech companies are grounded in solid business logic.
