Why Do Currency Traders Monitor Major Market Benchmarks?

Each currency pair reflects the relative opinion of two economies and their respective central banks. It takes into account the comparative appeal of two locations to the capital of investors around the world. By focusing on one currency pair alone, traders read only one line of a very long piece of writing.

Since all tradeable information already is expressed in benchmarks, these will be the core components to get a good “environment” view for a position. A dollar index, a two-year yield spread and a volatility gauge together form a very good insight into the state of the market for positions with a time span of weeks to months.

Reading currency strength across a basket rather than a pair

When the EURUSD pair decreases in value one immediately has to determine whether the euro has decreased in value or the dollar has increased in value. This has significant implications for how one should express a view on the currency. A firm broad dollar allows one to take a view against a weaker currency entirely while a decrease in value of the euro specifically may result in positions in cross currency trades such as the EURGBP or even EURAUD having a cleaner move and lower funding costs than in the EURUSD.

Anyone building this habit should start with a structured guide to DXY trading before deciding how much weight the index deserves in a given setup, because even those who never take a position in the index itself benefit from watching it daily as a great proxy for European flows and a terrible indicator of trends in Asian and Latin American currencies. Traders that trade in currencies such as USDCNH or USDMXN would instead look to trade weighted indices such as CNH10TW or MXN10TW and pay close attention to the divergence between the narrow index and the trade weighted index.

Building a strength view you can act on

• Compare each major against a basket over the same window, so relative performance is not distorted by one dominant pair.
• Check whether index moves are broad-based or driven by a single component reweighting the average.
• Track correlation stability. When historically linked pairs decouple, a local factor is at work and basket logic stops applying.

Rate differentials and the curve behind them

One of the few anchors that hold for long periods of time on the major currency pairs is short-dated yield spreads. A two year government yield, for example, gives a reasonable sense of the market’s expectations of the central bank’s policy over the coming weeks and months. While the price of a currency pair can drift up or down for months on end as the spread widens or narrows, there is typically no accompanying news headline.

However, being long of a steepening curve (even with higher yields) can have vastly different consequences than a short term wealth effect on a currency, A steepening curve due to growth is good for a currency, whereas a steepening of yields due to rising supply in the face of still eroding fiscal positions could subdue gains even as yields are increasing for a currency. The real yield adjusted for the breakeven inflation in a long term bond would typically allow a trader to discern between these two scenarios, and then cross-currency basis and forward points would reveal the true cost of funding a long position on a currency, making what initially seemed like an attractive differential worthless.

Economic releases and the expectations they move

Data’s value lies in how it affects the market’s view of the expected policy path, not its absolute level. So a strong print in a fully priced environment will have a smaller impact than a positive surprise above expectations in a cutting environment. Surprise indices, of course, express releases against the market’s consensus estimates for past releases and hence are superior to simply the print itself.

Ranking releases by the reaction they produce

Their usefulness for the direction of trade far exceeds their use for quantifying trade in terms of volume however. As for trade balances, almost by definition, they have very little short-term impact but then go on to account for multi-quarter movements that rate spreads cannot explain.

Sentiment gauges as a filter on position size

Risk appetite or the way investors feel about investing in assets in general is a major driver of currencies and determines whether fundamentals (fundamental analysis) matter for a currency or not. Whether the S&P500 stock index goes up or down, or the volatility of stocks (measured by the so-called VIX) increases or decreases, high yield credit spreads open up or contract and the price of gold goes up or down significantly, in such circumstances funding currencies such as the Japanese Yen and the Swiss Franc appreciate in value against other currencies, even if they offer lower interest rates than said currencies. This makes for very volatile conditions in which assets that offer high yields and have a strong positive outlook are traded in carry trades that however unwind very quickly when the attitude towards risk worsens and reverse trade positions suffer significant losses.

Three indicators are worthy of monitoring on a daily basis as part of a broader market analysis.

1. Implied volatility across tenors, since a steep front end signals event risk rather than trend.
2. Risk reversals, which show where the option market prices asymmetry in a specific pair.
3. Positioning data from futures reports and dealer surveys, read as a contrarian input at extremes.

Using benchmarks to size rather than to predict

The most logical use of these views is for calibration. As mentioned before, the interest rate spread can determine the direction. Sentiment can then determine how much size to take in the chosen direction, and the currency index helps to verify whether you are actually trading the view you believe in or diluting it.
