It’s all about yield. The back up in US bond yields in reaction to the US tax compromise from the Obama administration has been particularly sharp. US 10 year bond yields jumped around 35bps this week prior to a small correction in yields overnight whilst 2s were up 21bps. US bond yields are now back where they were in June, a fact that makes a mockery out of the Fed’s attempts to drive bond yields lower via quantitative easing (QE). Yields elsewhere increased too but by a smaller degree whilst equity market sentiment has been dampened by the rise in global yields although US stocks still ended higher overnight.
There is plenty of commentary discussing the impact on currencies of the move in bond yields so it’s worth looking in more detail how sensitive FX markets have been to yield. The most sensitive currencies i.e. those with the highest 3-month correlations with relative bond yield differentials (2 year) are the AUD/USD, EUR/USD, and of course USD/JPY. However, there is less sensitivity to gyrations in 10 year yields with no currency pair registering a statistically significant correlation with 10-year bond yield differentials over the past 3-months.
Assuming that US bond yields continue to push higher into 2011, with much lager increases in both nominal and yields expected, this means that AUD, EUR and JPY will face the most pressure relative to the USD. Moreover, the stimulus measures agreed by the US administration will likely lead to many analysts penciling in higher growth forecasts over 2011 whilst reducing the prospects of QE3 from taking place, all of which is USD positive. I still retain a degree of caution in Q1 2011, especially with regard to a potential bounce in EUR, especially if the ECB becomes more aggressive in its bond buying, but even so, any EUR rally is likely to prove termporary.
The impact of higher US yields on the AUD may be more limited however, despite the high correlation with relative bond yields, as Australian bond yields are also likely to rise somewhat given the resilience of its economy. This was clearly demonstrated by Australian November employment data released overnight revealing yet another consensus beating outcome of +54.6k, with all the gains coming from full time employment. Against the background of a generally firm USD, the best way to play AUD resilience is via the NZD, with the currency pair likely break through resistance around 1.3220 (21 October high).
