[MARKET UPDATE] USD/JPY drips briefly from 156.54 to 156.24 before stabilising around 156.47; news flow light; following similar action around 11:53 BST, 12:50 BST, and 14:20 BST

Repeated shallow dips in USD/JPY at elevated levels, without an identifiable catalyst, fit the pattern of market testing around intervention risk rather than genuine repositioning. Episodes of this kind, where the pair sits near levels Japanese authorities have historically defended, tend to produce brief, quickly retraced selloffs as participants probe for official flows; a drip of a few dozen pips that stabilises within minutes is the signature of stop-triggering or thin-liquidity noise, not the sustained, impulsive move that actual Ministry of Finance selling via the Bank of Japan has produced in past episodes, which has typically been orders of magnitude larger and followed by verbal confirmation. The distinction worth drawing is between flow-driven dips, which decay, and policy-driven dips, which hold and extend. Prior form from the authorities has been to escalate rhetorically first, with language about excessive or speculative moves, before any action, so the tells are the tone of official commentary and any acceleration in the pace of the move. Nothing in this price action indicates a change in the underlying driver, which remains the rate differential between the two central banks. Worth noting is simply the recurrence: repeated tests at similar times of day suggest positioning is being worked, not abandoned.
