There is only one thing that really matters these days, and it is global USD liquidity. We operate in a dollar-based world, so USD liquidity serves as a key driver of the global economy and financial markets. Our favorite dollar liquidity indicator is the evolution of USD money supply in major economies.
In chart 1, we track USD liquidity based on the evolution of the monetary aggregate M2 in the 25 largest economies, converted into USD and minus the evolution of M3 in the United States. This chart tells us much more than any other on what has happened in 2018 and what we should expect in 2019 if the current trend is not reversed.
Since March 2018, our liquidity indicator has sharply declined to reach a two-year low. It is a clear signal that the momentum in global growth is slowing down, leading to deteriorated financial conditions, higher USD funding costs and a sell-off of risk assets. This largely explains the emerging market turmoil that occurred this past spring and summer.
