I learned about a new economic data series available in SlopeCharts called Net International Investment Position (NIIP). The simplest way to think of this clumsily-named creature is as a balance sheet for a country. If a country owns a trillion dollars worth of overseas assets and owes half a trillion dollars to overseas creditors, then it has a positive NIIP of half a trillion dollars. If the figures were reversed (a mere half trillion assets but a trillion debt), then would have a negative NIIP. The first would be a creditor nation and the latter a debtor nation.
Below is a chart of the United States NIIP since 1976. Hard as it may be to believe, in the mid 1970s the U.S. was a creditor nation, Since then, if you look very, very carefully, you can see there has been a slight downturn.
