EUR/USD Has Quietly Gone Bid This Week

 | Feb 26, 2020 03:57PM ET

The last few days have been the most volatile since Q4 2018 for stocks. Many world indices have given up 2020 gains (some from all-time highs) and are currently trading lower for the year. With stocks moving lower, one currency pair that has been quietly moving higher is the EUR/USD.

In a time long ago before negative rates, U.S. stocks and EUR/USD moved together. However, once the ECB lowered rates into negative territory, the euro became a funding currency. This is known as a “Carry Trade.” People borrow euros at negative rates and buy riskier assets (this has been done with yen for years, which is why USD/JPY and the S&P 500 often move together). However, now that stock markets have been hit over recent days, people who are selling stocks (the riskier asset) need to buy back euros (the funding currency). The is know as “Unwinding of Carry Trade.”

Notice on the chart below that since the beginning of February, as stocks have been grinding higher, EUR/USD was moving lower. On February 20 (green vertical line) the correlation coefficient was -.90. For reference, a correlation coefficient of -1.00 is a perfectly negative correlation, meaning the as stocks move up (or down), EUR/USD moves down (or up) in lockstep. (Although the correlation coefficient has been moving higher the last few days, it is still negative. The fact that it is increasing just means that stocks have been moving lower at a faster pace than EUR/USD has been moving higher.)
