Copper prices posted the biggest weekly gain in two months as the metal that’s lagged far behind its peers this year gets a boost from signs that demand may strengthen in China, the biggest consumer. Zinc — the top metals performer of 2016 — posted its first back-to-back weekly drop since January.

Bonds

The yield on 10-year Treasury notes was little changed at 1.69 percent, poised to end the week higher by three basis points. Long-term bonds in the U.S. took a knock this week, lifting the 30-year yield to levels last seen in June, amid speculation monetary loosening around the world has about run its course.

Japan’s 30-year yield climbed to a six-month high during the week and rates on short-term securities fell on bets the BOJ will adjust policy to steepen the yield curve.

Russian bonds headed for their biggest weekly decline in two months after the Bank of Russia said its 50 basis-point rate cut on Friday is the last of the year because any more would risk rekindling inflation. The outlook on Russia’s junk credit rating was raised by S&P Global Ratings with the end in sight for the nation’s longest recession in two decades.

Germany’s 10-year bund yield fell three basis points, briefly turning negative for the first time in a week, and wiping out a weekly increase that had been driven by the European Central Bank’s failure to flag an immediate expansion of bond-buying program. Deutsche Bank’s riskiest bonds plummeted by the most since July after the DOJ claim.
