The US dollar index has weakened since mid-August 2018 although weakness in the broad trade weighted USD has become more apparent since the beginning of this month. Despite a further increase in US yields, 10 year treasury yields have risen in recent weeks to close to 3.1%, the USD has surprisingly not benefited. It is not clear what is driving USD weakness but improving risk appetite is likely to be a factor. Markets have been increasingly long USDs and this positioning overhang has also acted as a restraint on the USD.
Most G10 currencies have benefitted in September, with The Swedish krona (SEK), Norwegian Krone (NOK) and British pound (GBP) gaining most. The Japanese yen (JPY) on the other hand has been the only G10 currency to weaken this month as an improvement in risk appetite has led to reduced safe haven demand for the currency.
In Asia most currencies are still weaker versus the dollar over September, with the Indian rupee leading the declines. Once again Asia’s current account deficit countries (India, Indonesia, and Philippines) have underperformed most others though the authorities in all three countries have become more aggressive in terms of trying to defend their currencies. Indeed, The Philippines and Indonesia are likely to raise policy interest rates tomorrow while the chance of a rate hike from India’s central bank next week has risen.
As the USD weakens it will increasingly help many emerging market currencies. The likes of the Argentinian peso, Turkish lira and Brazilian real have been particularly badly beaten up, dropping 51.3%, 38.5% and 18.8%, respectively this year. Although much of the reason for their declines have been idiosyncratic in nature, USD weakness would provide a major source of relief. It’s too early to suggest that this drop in the USD is anything more than a correction especially given the proximity to the Fed FOMC decision later, but early signs are positive.
