Funds Boost Bullish Commodity Bets on Global-Growth Outlook

June 6 (Bloomberg) -- Funds boosted bets on rising commodity prices to the highest in four weeks, led by copper, amid signs that the global economic recovery will remain resilient and boost demand for raw materials.

Speculators raised their net-long positions in 18 commodities by 7.3 percent to 1.26 million futures and options contracts in the week ended May 31, government data compiled by Bloomberg show. That’s the highest since May 3. Copper holdings more than doubled. A measure of bullish agriculture bets also climbed as adverse global weather curbed crop production.

The Standard & Poor’s GSCI Spot Index rose for a fourth straight week as Chinese metal inventories plunged and droughts lingered in the Asian country and Europe, trimming prospects for wheat and cotton crops. The global recovery “is gaining strength,” the Group of Eight leaders said on May 27 after a summit in France. In the U.S., consumer sentiment rose to a three-month high in May, a private report showed last month.

“We are seeing a reasonable rate of growth in worldwide economic activity,” said Michael Cuggino, who helps manage $12 billion at Permanent Portfolio Funds in San Francisco. “The supply-demand associated with that growth, combined with a weaker dollar, probably explains the move into commodities.”

Copper prices have jumped 40 percent in the past year, while wheat has surged 75 percent and corn has more than doubled amid increasing demand from China and other emerging economies. Raw materials have also gained as investors boosted holdings as an alternative to the dollar, which has slumped more than 6 percent this year against a six-currency basket.

$130 Million

Investors poured $130 million into commodity funds in the week ended June 1, the second straight increase, according to EPFR Global, a Cambridge, Massachusetts-based researcher. The previous week had inflows of $702.8 million.

Managed-money funds and other large speculators boosted bullish bets on New York copper prices by 4,604 contracts to 7,304. The jump was the biggest since October 2009. Stockpiles of the metal monitored by Shanghai Futures Exchange have plunged 51 percent since mid-March.

“Destocking cannot continue indefinitely, and market participants will have to return to the market at the latest in the fourth quarter, if not for re-stocking, then at least for spot purchases,” Bank of America Merrill Lynch said in a report last week.

Agriculture Bets

Speculators raised their net-long positions in 11 U.S. farm goods by 4.6 percent to 756,629 contracts as of May 31, the second straight increase. Holdings of wheat jumped 14 percent, and bets on a cotton rally gained 12 percent, the most since August.

“It has basically been a year of the wrong weather at the wrong time, starting with the Russian droughts and then most recently excessive rains in the U.S.,” said Nic Johnson, who helps manage about $24 billion in commodities at Pacific Investment Management Co. in Newport Beach, California. Agriculture “prices could move materially higher because of low inventories and if we have below-trend yields of crops like corn,” he said.

Commodity demand may wane after manufacturing slowed from China to India last month, and the unemployment rate in the U.S. unexpectedly climbed.

“We do not think a global slowdown will last for months on end, but certainly, it very well could persist through the summer, in which case one should resist getting lulled in on the long side,” Edward Meir, a senior analyst at MF Global Holdings Ltd. in Darien, Connecticut, said today in a report.

The GSCI index fell 0.3 percent at 9:49 a.m. New York time, led by agricultural futures. Wheat in Chicago dropped as much as 1.9 percent as rain may improve yields in parts of Europe. Corn declined 1.1 percent.
