Daily Market Update – Wednesday, October 21, 2026

Japan's trade deficit came in wider than expected overnight, while the main event of the day is UK inflation at 06:00 GMT. With the Bank of England already split on rates, today's CPI could shape expectations for a November hike.

*Japan's trade balance releases at 11:50 PM GMT on Tuesday, which is early morning on Wednesday, October 21 in Tokyo.

Japan Trade Balance: Narrower Than August, but Wider Than Expected

Japan recorded a trade deficit of ¥536.6 billion in September, its fifth straight monthly deficit. That was a big improvement from August's deficit of about ¥1.1 trillion, which was the largest since January, but still wider than the ¥181 billion deficit economists expected.

Exports rose 16.7% from a year earlier, the 13th consecutive monthly gain, driven by AI-related chips and cars, although growth missed the roughly 20% forecast. Imports rose 18.9%, slower than August's 28.0% jump, partly because some crude oil shipments were delayed by tanker rerouting. The government expects crude arrivals to recover in October, so the import bill may rebound. For the first half of the fiscal year, the deficit reached ¥2.8 trillion, nearly double the year before, as higher oil prices pushed up import costs.

A widening deficit tends to weaken the Yen, because Japan spends more foreign currency on imports. A weak Yen helps exporters and Japanese stocks, but raises the cost of energy and raw materials at home. With the Yen averaging around ¥157 per dollar in September, traders will keep watching trade and inflation data for clues on the Bank of Japan's policy stance.

UK CPI: Another Step Higher Expected

UK inflation rose to 3.1% in August, up from 2.9% in July, driven mainly by transport and fuel costs, with core inflation steady at 2.6% and prices up 0.5% on the month. For September, the consensus is for another jump to 3.4%, the highest since December, with a smaller monthly gain of about 0.3%. Core inflation is also expected to accelerate, to around 2.8%, which would show the energy shock from the Middle East conflict spreading into the wider economy.

The release matters because the Bank of England held its Bank Rate at 3.75% in September by a 6-3 vote, with three members preferring an immediate increase to 4.0%. The committee expects inflation to rise further, and Governor Andrew Bailey has flagged the need to hike, though the timing remains vague. A reading at or above 3.4%, especially with a hot core figure, would strengthen expectations of a hike at the November meeting, which typically supports the Pound and lifts gilt yields while pressuring UK stocks. A softer print would reduce that pressure and could weigh on Sterling.
