I recently noticed an interesting phenomenon in the forex market. Last spring, the timing of US-Iran diplomatic negotiations and a batch of US economic data releases simultaneously triggered significant volatility in the global currency markets. I think this logic is worth analyzing in detail.

Starting with technical analysis, EUR/USD repeatedly tests the 1.0950 level, which is a key resistance. Once broken, it could directly target 1.1020. Meanwhile, USD/JPY is particularly sensitive to US Treasury yields, with 148.80 serving as an important support. These are key levels that traders focus on; any geopolitical or data shocks could lead to rapid adjustments.

On the geopolitical front, progress in US-Iran negotiations directly influences global risk appetite. I’ve observed that whenever Middle East tensions ease, safe-haven assets like the dollar and yen tend to lose attractiveness, while risk-sensitive currencies begin to strengthen. The underlying logic is clear: a stable geopolitical environment encourages investors to take on more risk, flowing into high-yield currencies. Conversely, when tensions escalate, funds tend to flock into the dollar, yen, and Swiss franc as safe havens.

Energy prices play a crucial role here. Historical data shows that during US-Iran dialogue periods, oil prices often decline, putting pressure on commodity currencies like the Canadian dollar. I roughly calculated that, based on an exchange rate of 1020 USD/CAD, a 10% drop in oil prices could push the CAD down by over 100 basis points. That’s why traders pay close attention to both crude oil trends and the USD/CAD currency pair.

Looking at economic data, indicators such as PPI, retail sales, and industrial output, while not as prominent as non-farm payrolls, are especially important for the Federal Reserve’s policy decisions. If the data exceeds expectations, the US dollar tends to be supported; if not, it may weaken. This directly influences interest rate expectations and, consequently, global capital flows.

My observation is that event days like these usually see increased volatility. Currency pairs related to oil, the Japanese yen, and the Swiss franc tend to exhibit clear directional movements. Experienced traders typically reduce their position sizes in advance or hedge with options because implied volatility tends to rise sharply.

From a longer-term perspective, if geopolitical breakthroughs truly improve the global risk environment, high-yield currencies may experience a rebound. However, if US economic data continues to show persistent inflation, the Federal Reserve may maintain a hawkish stance, keeping the US dollar strong. The tug-of-war between these forces will determine the tone of the forex market in the coming months.

It’s also important to note that the forex market is not isolated. Stock market performance, US Treasury yields, and gold prices all influence each other. Especially, the rise and fall of technology stocks often signal shifts in global risk appetite, which in turn impacts risk-sensitive currencies like the Australian dollar and New Zealand dollar. Additionally, the spread between US 10-year Treasury yields and German bund yields directly influences the EUR/USD movement.

Overall, these event-driven trading days test your ability to synthesize multiple market signals. You need to monitor geopolitical developments, pay attention to economic data details, and understand the interactions between different assets. Proper risk management, setting reasonable stop-losses, and avoiding excessive leverage are fundamental skills to survive in this high-volatility environment.
