The US Government Balance corresponds to the amount of BTC held in addresses controlled by US authorities. The metric includes seized funds, e.g. from the 2016 Bitfinex Hack or the 2012 Silk Road Hack. We constantly keep updating the set of addresses contributing to the total balance.

This is the Point-in-Time (PiT) variant of US Government Balance. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
