USD/JPY briefly traded just above 160.00 in Asia, its highest since late July, before reversing more than two yen to around 158.50 on a meeting readout and fresh intervention talk. The 158.50 level briefly broke by about 30 pips, then was reclaimed. Six weeks ago, Japan and the US conducted their first joint yen-buying operation since 1998: reported Japanese selling was near $60bn on the Thursday and $25bn on the Friday, followed by another tranche the next Monday, while the US leg was put at $5bn to $10bn. The pair slid from close to 164.00 to about 155.25, implying roughly nine yen of movement for more than $100bn, yet within five weeks it was back above 160.00.
Tokyo’s capacity to act is supported by access to a Federal Reserve facility to raise dollar liquidity against Treasury collateral, reducing the need to sell bonds outright, but operations have struggled against fundamentals that reassert quickly. Japan’s 10-year government bond yield hit 3% for the first time since 1996, a move framed by fiscal expansion and debt-service maths rather than tighter policy expectations. Attention turns to the Bank of Japan decision on 18 September and US data: jobless claims at 12:30 GMT are seen at 205K versus 203K, plus ISM services PMI at 14:00 GMT at 54.3 versus 54.1, with prices paid previously at 70.3; private payrolls were 38K versus 47K. Friday’s nonfarm payrolls are forecast at 58K versus a prior 23K jobs lost, unemployment at 4.1% and earnings at 0.3% m/m, with two Fed speakers due at 12:30 and 19:00 GMT. Technically, 160.00 aligns with the 50-day EMA, support is 158.50 then 158.00, while the 200-day EMA sits near 157.50 and the intervention low at 155.25; Stoch RSI is near 87.
Derivative Strategy: Positioning For USD/JPY Strength
We recommend that derivative traders prepare for continued upward momentum on USD/JPY despite ongoing intervention warnings from Tokyo. Even though the pair dropped to 158.50 after flirting with 160.00, these pullbacks represent buying opportunities rather than a trend reversal. History shows us that even massive multi-billion dollar joint interventions only provide temporary relief before the market’s underlying forces take over again.
We favor using bullish strategies, such as buying call options, as long as the key support floor at 158.50 remains intact. A solid bounce from this level should set our sights on a retest of the 160.00 handle and potentially the peak near 164.00. We would only turn bearish and close out long positions if the pair manages a daily close below the 200-day Exponential Moving Average near 157.50.
Macro Context: Yields, Central Banks, and Key Data Events
Although Japanese 10-year bond yields recently hit a multi-decade high of 3%, this move reflects heavy government debt supply rather than expectations of aggressive rate hikes. Even if the Bank of Japan raises rates on September 18, the yield gap with a Federal Reserve that meets on September 16 will remain over 2.5 percentage points wide. This massive yield differential means we expect carry traders to quickly rebuild their short-yen positions after any official dip.
Today’s jobless claims and tomorrow’s US nonfarm payrolls are the critical events that will decide how fast we retest the 160.00 level. Strong US economic data will likely force the pair back to 160.00 before the Bank of Japan even has a chance to meet. To navigate this volatility, we should utilize structured barriers or risk reversals to protect our capital against sudden, short-lived intervention spikes.
