The US dollar was little changed against the yen, with USD\/JPY trading in the low 159.00s and around 159.02 on Friday. In Japan, July inflation picked up, as headline consumer prices rose 1.9% year on year and core measures firmed, while August business surveys beat expectations. Rate expectations have followed: swaps imply roughly an 80% chance the Bank of Japan raises rates at its September meeting, lending support to the yen.<\/p>\n
US data pulled the other way. Flash S&P Global PMI surveys showed private-sector activity strengthening, with the Composite index rising to 56 from 54.5 on a stronger Services reading, even as Manufacturing slipped and missed forecasts; that backdrop underpins the Federal Reserve\u2019s higher-for-longer stance and helps the dollar despite a weekly decline. The US Treasury said it would at least double buybacks of longer-dated debt to ease bond-market strains and cap yields, while Washington\u2019s shift towards sanctions on Iran improved risk appetite, which typically weighs on the safe-haven yen. Technically, USD\/JPY held above the 100-period SMA (158.81) and 20-period SMA (158.91), with RSI near 51; resistance sat at 159.04 then 159.13, and support at 158.91, 158.87, 158.81 and 158.63.<\/p>\n
We believe derivative traders should prepare for a range-bound environment in the coming days as USD\/JPY consolidates around the 159.00 level. With the short-term moving averages clustered tightly between 158.81 and 158.91, writing near-the-money options spreads can help capture premium decay. Historically, late August trading volumes drop by up to 20%, which typically suppresses major breakouts before big central bank events.<\/p>\n
As we approach next Friday’s Jackson Hole debut of Fed Chair Kevin Warsh, we expect implied volatility to rise. Derivative traders should look to buy USD\/JPY strangles to position for a breakout once the Fed’s policy path becomes clearer. Past changes in Fed leadership have historically triggered an average 15% spike in currency volatility as the market adjusts to the new chair’s tone.<\/p>\n
Meanwhile, Japan’s firm 1.9% inflation and strong business surveys have pushed the probability of a September Bank of Japan rate hike to 80%. We recommend utilizing bearish put options to protect against a sudden drop toward the key 200-day moving average. If the central bank tightening is confirmed on September 18, the yen could see rapid gains as remaining carry trades unwind.<\/p>\n
However, strong US data like the Composite PMI jumping to 56 will continue to put a firm floor under the dollar. Because of this tug-of-war, we favor using knock-out barrier options with floors set just below 158.00 to keep premium costs low. This allows us to stay protected against a yen rally without overpaying for protection in a highly contested market.<\/p>\n\n\n\n
