In terms of macroeconomics, the US core Producer Price Index (PPI) for January 2026 exceeded expectations both year-on-year and month-on-month. The core PPI increased by 3.6% year-on-year, surpassing the expected 3% and the previous value of 3.3%. Month-on-month, it rose by 0.8%, higher than the anticipated 0.3% and the prior figure of 0.6%. This indicates rising inflationary pressures at the production end, suggesting that upstream price transmission remains relatively strong.

The US Conference Board Consumer Confidence Index for February 2026 saw a slight rebound but remained at a low level. The index climbed to 91.2, above the expected 87.1 and the previous (revised) value of 89.0. The Present Situation Index decreased to 120.0 (from 121.8 previously), while the Expectations Index rose to 72.0 (from 67.2). This reflects a fragile recovery in consumer sentiment.
