Efforts to tame inflation in the US have pushed up the dollar and global borrowing costs.

Consumer prices in the US rose more than expected last month in a sign that the inflation fight in the world's largest economy is far from over.
Inflation, the rate at which prices rise, was 8.2% in the 12 months to September, down from 8.3% in August.
Despite the fall, the figure was still higher than forecast.
Inflation in the US is being closely watched as the US central bank's efforts to tame the problem push up the dollar and global borrowing costs.
The rate is well above the central bank's 2% target and means the Federal Reserve is likely to continue to keep raising interest rates in an attempt to cool rising prices.
"The Fed needs to react at the next meeting and continue to keep policy tight until there is some sign that inflation is under control," said Neil Birrell, chief investment officer at Premier Miton Investors.
"This print raises the level of uncertainty and is bad news for the economy overall, but for consumers in particular. The peak in interest rates will, in all probability, be higher now. It's difficult to find any positives in this for the economy or markets."
