Major central banks kept policy steady, with the Federal Reserve, Bank of England and Bank of Japan leaving overnight rates unchanged, and markets also received a thin Fed statement that added three dissenters: Logan, Hammack and Kashkari. Fed chair Kevin Warsh offered no forward guidance, while referencing higher nominal and real yields as a tightening force for financial conditions. In FX, USD/JPY fell about 600 pips, or 4%, and slipped below its 200-day SMA for the first time since October 2025 after Japan’s Ministry of Finance intervened in coordination with the US to arrest the yen’s slide from 40-year lows; it was the first joint action since 2011. Rate pricing implies two BoJ hikes by March 2027, and markets now assign roughly a 40% chance of a September hike, up from 20% a week earlier.
Risk appetite improved after Donald Trump called off a planned attack on Iran, which he said would have been the biggest since World War Two; talks are reportedly due today, with the Strait of Hormuz still largely closed. Brent and WTI dropped about 8% at the open, the dollar index eased, and US Treasury yields fell, while European and US equity index futures rose even as Asia-Pac shares weakened on declines in South Korean chipmakers. Attention turns to US data, with ISM manufacturing due today at 2 pm GMT; the median forecast is 54.0 versus 53.3 in June, with estimates spanning 57.0 to 52.8. New orders and employment each carry 20% weight, while July non-farm payrolls are expected at about 83,000 versus 57,000 in June, following June YY CPI, PPI and PCE prints that were below expectations.
Currency Volatility and Trading Strategy
We are facing a highly volatile period as derivative traders adjust to the Federal Reserve’s silence and the historic joint U.S.-Japan yen intervention. The recent 4% drop in USD/JPY, which pushed the pair below its 200-day moving average, shows that the market is taking these currency moves very seriously. Historically, joint interventions like the one in 2011 have successfully reversed long-term currency trends, meaning we should avoid blindly buying the USD/JPY dip this time.
Instead of trading spot forex with high leverage, we should consider long JPY call options to protect against sudden intervention spikes. Japan’s Ministry of Finance has shown it is willing to spend tens of billions of dollars, similar to its estimated $35 billion yen-buying spree in mid-2024, to defend the currency. This threat of further joint action keeps the risk skewed to the downside for USD/JPY, making cheap out-of-the-money JPY calls an attractive volatility play.
Interest Rates, Macro Data, and Risk Sentiment
On the interest rate front, the lack of forward guidance from Chairman Warsh has steepened the U.S. yield curve as the market questions the Fed’s commitment to price stability. We can position for this continued steepening by utilizing treasury options or yield curve spread trades. Since two major inflation reports are still due before the September meeting, we expect near-term rate volatility to remain elevated.
With the ISM Manufacturing PMI projected at 54.0 today and Friday’s non-farm payrolls expected at 83,000, US economic data will dictate the dollar’s near-term direction. If we see a significant miss in these numbers, it will likely accelerate the USD sell-off and support the yen’s recovery. For derivative traders, shorting USD on strength following any brief positive data spikes looks like the most sensible risk-reward setup.
The sudden de-escalation of geopolitical tensions has dragged oil prices down by 8%, boosting risk-on sentiment in equity futures today. We should look at implied volatility in energy derivatives, which remains bloated, to sell premium through credit spreads as the immediate panic subsides. However, because the Strait of Hormuz remains largely closed, we must keep position sizes small to manage the risk of sudden supply headlines.
