Trump's MFP Leads to WTO Violation?

That's the Congressional Research Service's tentative conclusion--US may be billions over its "amber box" limit in 2019.. Its conclusion:

According to the scenarios developed in this analysis, including a projected set of market conditions, the United States may potentially exceed its cumulative amber box spending limit of $19.1 billion in 2019. Excessive amber box payments in 2019 could result from the addition of large MFP payments to the traditional decoupled revenue support programs ARC and PLC.
However, this analysis found that U.S. compliance with WTO amber box spending limits was very sensitive to a change in market conditions and market valuations. Noncompliance hinges on many key market factors that are currently unknown but would have to occur in such a manner as to broadly depress commodity prices through the 2019 marketing year (which extends through August 31, 2020, for corn and soybeans). Another crucial uncertainty is how the U.S.-China trade dispute—with its deleterious effects on U.S. agricultural markets—will evolve.51 Resolution of the U.S.-China trade dispute and an improved demand outlook could lead to higher commodity prices and output values while lowering payments under countercyclical farm programs such as MAL, PLC, and ARC. Such a turn of events could help facilitate U.S. compliance with its WTO spending limits.
