Nikkei Jumps 2,342 Points to 66,300 as Middle East Tensions Ease

The Nikkei jumped 2,342.91 points on 5 August to close at 66,300.44, a 3.66% gain and its first finish above 66,000 in two weeks. The trigger came from outside Japan: easing Middle East tensions sent crude sharply lower after Wall Street hit a record, and cheaper oil is never just another commodity story for an economy that imports nearly all of its energy. Lower input costs and a better trade balance both feed straight back into the yen.

Keep the scale honest. At today's index level 2,300 points is 3.66%; at the 30,000 levels of a few years ago the same move would have printed as 1,100 points. Percentage and volume matter, headline point counts do not.

Three paths from here. Calm persists and cheap oil plus a strong earnings season carry the rally, though a firmer yen after the 31 July joint intervention would erode exporter earnings and hand leadership to domestic and financial names. Or the calm proves temporary, oil rebounds, and this becomes a one-day reflex. Or the Bank of Japan follows the intervention with a September hike, lifting banks and squeezing property.

For Taiwanese investors the practical point is that most locally listed Japan ETFs are unhedged: returns are index moves multiplied by currency moves, and that multiplier is about to work in the opposite direction from the past two years.
