The 10-year U.S. Treasury yield climbed to 4.818% on the 2nd, its highest level in 34 months since Nov. 1, 2023, before closing at 4.782% as bargain hunters emerged. The 2-year yield reached 4.410% and the 30-year yield 5.296%. New York Federal Reserve President John Williams helped calm markets by saying inflation was gradually easing as some tariff effects faded, although Wall Street expects yields to rise further amid higher international oil prices and expanding government debt worldwide. Asian markets also saw abrupt volatility: the KOSPI fell 1.88% in little more than 10 minutes around 2 p.m. on the 3rd, reaching 6,439.49 before ending at 6,579.48, up 0.26%. Reports of an Iranian attack on a U.S. military base, expectations of a possible 50-basis-point Bank of Japan move and swings in derivatives markets contributed to the reversal. Separately, Lumentum Holdings reported fiscal fourth-quarter 2026 revenue of $1.01 billion, up 109%, while its operating margin widened to 36.6%. Broadcom's fiscal third-quarter 2026 revenue rose 86% to $29.591 billion, including a 221% increase in AI chip revenue to $16.7 billion, but its shares fell nearly 5% after fourth-quarter guidance missed expectations. TSMC said it is building about 20 fabs worldwide but still cannot meet explosive AI demand, while SK Group Chairman Chey Tae-won said data-center memory supply is 20% to 30% below demand. Capital Group increased its stakes in KT&G and JB Financial Group while reducing its holding in SK hynix.
