Fundamental Evaluation Series: USD/CNH vs. 2-year yield spread

This chart shows the relation between U.S. - China 2-year yield spread and the Dollar/Chinese yuan exchange rate since 2013. It is visible even with naked eyes that the two has enjoyed a very close relationship. It can also be seen that the infamous August 2015 devaluation of the Chinese yuan by the People’s Bank of China (PBoC) that led to a global financial turmoil could very well be the result of rising U.S./China 2-year spread.

Since March 2015, the yield spread between the United States and China’s 2-year bond rose from -276.6 basis to -131.3 basis points in favor of the dollar by June, while the exchange rate was kept flat around 6.2 per dollar. Finally, PBoC had to respond by a one-time devaluation of the yuan to 6.46 for per dollar. This shows, how significant the spread is for the pair.  

The spread also explains the recent strengthening of the yuan against the USD. Since the U.S. election, the yield spread has widened from -129 basis points to -216 basis points as of today, in favor of the yuan. Naturally, the exchange rate has responded by declining from 6.95 per dollar to 6.54 per dollar, as of today.

We would like to recommend close watching of the spreads and communications from both central banks.

We forecasted the exchange rate to reach 6.38 per dollar.
