Three explanations on why the euro has remained so strong
Bank of America Merrill Lynch looks at what's kept a bid under the euro
They ask, "why is EUR defying gravity?
1. Euro had become the favorite funding currency the world over with significant leverage being added in the past year. Given the move we've already seen, and the fact that higher vol lowers the risk adjusted return for your carry, risk aversion should lead to unwinding of these carry trades which require buying of EUR.
2. Price action would suggest there are still residual short Jpy-X (inc eurjpy) positions being unwound as well as general position reductions supported by internal and CFTC stats.
3. Many portfolio managers may have been significantly underweight euros for some time now. As the euro has depreciated and European fixed income has sold off materially, this would provide a good entry point to slowly start to reduce/ take profit on underweight positions."
There have been a series of notes along these lines from banks and research firms and there's nothing close to a definitive answer. At some point, the chart tells the story and it's a story of resilience. We're now in the process of the fifth attempt to break above 1.14. Once the May high of 1.1467 breaks, there isn't much in the way of resistance until the 200-day moving average at 1.1705 and the pre-QE lows at 1.2246.
