Where do these numbers come from?

FRED, published by the Federal Reserve Bank of St. Louis, for the series produced by US federal agencies, and the Bank of Korea statistics system (ECOS) for series the Bank of Korea itself compiles. Copyrighted index series such as the S&P 500, the Nasdaq composite and the VIX are not republished here.

Why does the won rate differ from the Seoul close?

This is the Federal Reserve’s New York reference rate, so it differs from the Seoul market close and from rates quoted by Korean banks. Use it for the trend rather than for a precise level.

What does an inverted yield curve mean?

It means the 10-year yield sits below the 2-year. It has often appeared ahead of past US slowdowns, which is why it gets quoted, but the lag has been long and uneven, so it does not tell you when anything will happen.

How often is this updated?

Twice a day. When a source agency posts late or revises a figure, the number here follows. There are no new readings on weekends or US holidays.
