With the yen trading close to the 160-per-dollar mark on Monday, Asian currencies moved in mixed directions as a fresh climb in oil prices pushed investors toward safer assets across the region. The Japanese currency’s weakness once again drew attention to the limits of official intervention.
The renewed slide came as the effects of earlier government action to prop up the yen appear to be fading, leaving the currency exposed to the same pressures that drove it lower earlier in the year. Higher crude prices tend to weigh heavily on Japan, which imports nearly all of its energy and pays for it in dollars.
For households and businesses, a softer yen combined with pricier oil means steeper import bills and continued upward pressure on the cost of fuel, food and imported goods. Japan has already contended with the twin strain of rising energy costs and a depreciating currency feeding into inflation.
Goldman Sachs told clients that while the boost from intervention is wearing off, one popular yen strategy should keep working. Relative-value carry trades — borrowing in low-yielding currencies to buy higher-yielding ones — are expected to continue delivering returns even as the intervention-driven trade fades.
That distinction matters for global investors who have leaned on the yen as a cheap funding currency. As long as Japanese interest rates stay far below those elsewhere, the gap that makes carry trades profitable remains intact, regardless of short-term swings around policy moves.
Other regional currencies drifted without a clear direction as the oil rally sharpened risk-off sentiment. Rising crude prices complicate the calculations of central banks across Asia, many of which are already weighing inflation risks against slowing growth.
The 160 level has become a psychological threshold for markets watching whether authorities in Tokyo will step in again. Previous episodes have shown that intervention can slow the yen’s decline but rarely reverses the deeper forces pushing it down, chiefly the wide interest-rate divide with the United States.
For consumers, the immediate takeaway is that imported inflation is unlikely to ease while the yen stays weak and oil stays firm. Travelers heading to Japan may find their money stretching further, but residents face the harder side of the same equation at the pump and the checkout.
