CNY influence on Asian FX continues to grow

Asian currencies remain generally well supported both by a softer tone to the USD in general as well as a stronger Chinese currency, CNY. Since the USD/RMB high of 6.3964 on 25 July the RMB has appreciated by around 2.4% vs. USD. This equates to an annualized pace of appreciation of around 6.2%. The RMB is unlikely to continue to strengthen at such a rapid pace and could even be prone to a softer tone into year end.

Potential renewed weakness in the CNY could presage downside risks to Asian currencies. Also worth noting is the fact that equity portfolio capital inflows to Asian have slackened over recent weeks (Indonesia, Philippines and Taiwan registered outflows over October), a factor that could also pose risks to Asian currencies.

The influence of the RMB on Asian FX has continued to grow. Correlations or sensitivities between Asian currencies and the CNY remain are stronger than Asian FX sensitivities to USD movements. The implication is that USD index gyrations are having less influence on Asian currencies.

The most correlated currencies with the CNY are KRW, SGD and TWD although all Asian currencies with the exception of the INR register statistically significant correlations with the movements of USD/CNY. Notably our quantitative models show that the KRW, SGD and TWD are overbought relative to their short term fair value estimates.

While the USD is still influential in driving some Asian currencies several currencies including KRW, CNY and IDR do not possess a statistically significant sensitivity to the USD over the past 3-months. Should the CNY undergo renewed weakness it will mean that the currencies noted above namely KRW, SGD and TWD will be the most vulnerable to weakness given their high sensitivity to CNY.
