Wednesday's early European trading saw a small decline in the value of the US dollar as it eased from the highest level in two months before this week's Jackson Hole Symposium's additional hints on monetary policy.

The 10-year Treasury yield has dropped from its 16-year high of 4.366% on Tuesday to trade around 4.3% on Wednesday, which has caused the currency to slightly depreciate.

The prospect of higher Fed rates for longer in the context of a robust economy is one of several reasons why yields have risen. When the U.S. August flash PMIs for manufacturing and services are released, more proof of this is likely to emerge, with expectations that the composite index will continue to be in expansion zone.

EUR/USD advanced by 0.1% to 1.0855.

GBP/USD ticked up 0.1% to 1.2748 before the publication of August flash PMIs for manufacturing and services for both Britain and the euro region overall.

USD/JPY 0.2% to 145.66, on Japanese PMI figures that indicated some resilience in local manufacturing activity during August.
