USDJPY-Nikkei Correlation Suggests 12.5-Year High At 124.00 In Play

It’s the dollar’s world; we all just live in it.

The US dollar tagged a new 12-year high at 98.50 in today’s European session on the continued positive afterglow from sooner rather than later .

While EURUSD is understandably garnering all the headlines today, USDJPY is also on the verge of a major breakout above its 7.5-year high at 121.84. Beyond the broad-based dollar strength, USDJPY’s close correlation with the Nikkei equity index is also driving the pair higher. Historically, the performance of USDJPY has provided a reliable proxy for global equity markets and risk assets as a whole. This correlation makes sense: when traders are feeling more optimistic (high risk appetite), they tend to buy stocks and sell yen to fund carry trades in higher-yielding currencies, but when they are more pessimistic (risk averse), traders have to unwind these trades by buying back yen and selling equities.

Beyond the general risk relationship, the correlation between USDJPY and Japan’s Nikkei 225 index is further strengthened by the index’s heavy weighting in export-oriented companies. When the value of the yen rises (USDJPY falls), Japanese exporters see reduced demand from overseas buyers. On the other hand, a fall in the value of the yen (USDJPY rise) makes Japanese goods “cheaper” for foreigners, boosting Japanese sales and driving Japanese shares higher. As the chart below shows, this correlation has been reliable since Q4 of last year, though of course there is no guarantee that it will stay as consistent in the future. In fact, based on the chart below, the current level of the Nikkei (18,500) would be consistent with USDJPY trading closer to 124.00 than its current level of 121.00.
