USD/CNY: It's Going To 7

 | Oct 16, 2018 12:12AM ET

Here are a couple of charts on a topical and divisive subject—the outlook for the Chinese yuan. This is something I've spent a lot of time looking at, and have been bearish renminbi vs US dollar for a few good reasons. Before we look at the charts, let's talk about why.

It's basically 3 reasons, and it's mostly about the fundamentals: 1. Economic divergence (China's economy is slowing vs US accelerating); 2. Policy divergence (Fed hiking rates + QT vs PBOC cutting RRR, easing liquidity); 3. Politics (CNY weakness provides a timely offset against tariffs, and eases domestic pressure).

1. Interest Rate Differentials: The first chart maps the USDCNY against monetary policy rate differentials. Interest rate differentials are a fairly well established indicator for exchange rates because they reflect incentives e.g. borrowing in one currency (lower interest rate) and investing in the other (higher interest rate), and also reflect divergences in economic developments and monetary policy cycles. If you take this chart literally, the USDCNY could end up going well beyond 7 ...on that note, this is basic economics, not competitive devaluation.
