The Japanese yen found a tentative footing in Asian trading on Friday, hovering around the 158 mark against the US dollar as investors remained on high alert for possible intervention from Tokyo. The currency had weakened sharply earlier in the week, prompting verbal warnings from Japanese officials, though no confirmed action has been taken so far. Market participants are now pricing in a higher risk of direct intervention should the yen approach the 160 level.
Across the Pacific, the US dollar index dipped slightly ahead of the release of June's Personal Consumption Expenditures (PCE) price index — the Federal Reserve's preferred inflation gauge. Traders are also eyeing a scheduled speech by Fed Governor Christopher Waller, whose recent comments have been hawkish. Any sign that the Fed is in no rush to cut rates could reignite dollar strength and put renewed pressure on emerging market and Asian currencies.
For UK investors, the yen's instability carries particular significance. A weaker yen tends to boost the value of Japanese equities held in UK pension funds, but it also raises the cost of imported goods from Japan, potentially feeding into UK inflation data. The FTSE 100, which includes a number of companies with significant Asia exposure, has been sensitive to currency swings in the region. The index was little changed in early trade, with investors adopting a cautious stance ahead of the US data.
Analysts at a London-based currency consultancy noted that the pound has been relatively stable against the dollar this week, but warned that a sustained yen sell-off could spill over into broader risk-off sentiment. 'If the yen breaks through 160, we could see a flight to safety that lifts the dollar and hits sterling,' one strategist said. 'UK pension funds with unhedged Japanese equity exposure should be watching the 158-160 range closely.'
The broader Asian FX complex was mixed, with the Chinese yuan steadying after recent weakness and the South Korean won edging higher. Markets are now pricing in a roughly 60 per cent chance of a Fed rate cut in September, though much depends on the PCE print. A hotter-than-expected reading could delay those expectations and strengthen the dollar further, with knock-on effects for UK import prices and gilt yields.
