Will the central bank rebalance its currency share? We explore this problem by using different types of data sets from the global summary level, country level, and panel context. At the decomposition level, we found a mixed bag; some economies did rebalance, while others did not. However, our random analysis shows that the United States has not rebalanced. Switzerland is an advanced economy that has not joined the G3, and it does seem to be rebalancing foreign exchange reserves. Its currency composition has nothing to do with changes in the US dollar exchange rate. We also explored the issue of rebalancing through panel data analysis and found that on average our sample economies will not be rebalanced. Emerging market economies (EME) will not rebalance, while advanced economies will rebalance. Larger economies maintain a stable currency composition, while reserves in smaller economies are more susceptible to exchange rate shocks.
The analysis relies on data at the central bank level. For example, here are the reserves of the Swiss National Bank.
