What is the DailyFX Volatility Index:

The DailyFX Volatility Index measures the general level of volatility in the currency market. The index is a composite of the implied volatility in options underlying a basket of currencies. Our basket is equally weighed and composed of some of the most liquid currency pairs in the Foreign exchange market.

In reading this graph, whenever the DailyFX Volatility Index rises, it suggests traders expect the currency market to be more active in the coming days and weeks. Since carry trades underperform when volatility is high (due to the threat of capital losses that may overwhelm carry income), a rise in volatility is unfavorable for the strategy.

What are Risk Reversals:

Risk reversals are the difference in volatility between similar (in expiration and relative strike levels) FX calls and put options. The measurement is calculated by finding the difference between the implied volatility of a call with a 25 Delta and a put with a 25 Delta. When Risk Reversals are skewed to the downside, it suggests volatility and therefore demand is greater for puts than for calls and traders are expecting the pair to fall; and visa versa.

We use risk reversals on USDJPY as global interest are bottoming after having fallen substantially over the past year or more. Both the US and Japanese benchmark lending rates are near zero and expected to remain there until at least the middle of 2010. This attributes level of stability to this pairs options that better allows it to follow investment trends. When Risk Reversals move to a negative extreme, it typically reflects a demand for safety of funds - an unfavorable condition for carry.

How are Rate Expectations calculated:

Forecasting rate decisions is notoriously speculative, yet the market is typically very efficient at predicting rate movements (and many economists and analysts even believe market prices influence policy decisions). To take advantage of the collective wisdom of the market in forecasting rate decisions, we will use a combination of long and short-term, risk-free interest rate assets to determine the cumulative movement the Reserve Bank of Australia (RBA) will make over the coming 12 months. We have chosen the RBA as the Australian dollar is one of few currencies, still considered a high yielders.

To read this chart, any positive number represents an expected firming in the Australian benchmark lending rate over the coming year with each point representing one basis point change. When rate expectations rise, the carry differential is expected to increase and carry trades return improves.
