As we saw with many other metals, nickel prices were hammered earlier this year due to anaemic demand. Although the metal has rallied recently thanks to an uptick in stainless steel demand (among other factors), nickel prices are still a far cry from their early 2007 peak. We believe changes within the nickel industry could prevent a repeat of the 2006/2007 bonanza. Namely, a shift toward lower-nickel-content stainless steel has important implications for long-term nickel demand, while the emergence of Chinese nickel pig iron (NPI) production has introduced a swing producer to act as a pressure release valve when demand and prices are high.
Nickel Basics
Roughly two thirds of total nickel consumption goes into the production
of stainless steel. Given its anticorrosive properties and the fact that
it's easy to clean, stainless steel is widely used in food and chemical
processing equipment and food service. Other uses of nickel include
alloys for the aerospace, power generation, and automotive industries.
As with many other metals, China has become a major consumer of nickel,
accounting for approximately one fourth of global demand. The five-year
period to 2006 saw rapid growth in global nickel consumption (5% per
year, on average, according to the International Nickel Study Group).
After 2006, however, nickel demand fell significantly due to weakening
economic activity and increasing substitution of lower-nickel-content
stainless steel. On the supply side of the equation, nickel production
is relatively concentrated, with the top four producers (Norilsk
Nickel, Vale,
BHP
Billiton, and Xstrata)
contributing approximately half of the world's total supply. Nickel
prices have been quite volatile in recent years, with a surge in demand
driving prices to heights of nearly $55,000 per metric ton in early
2007. This spring saw prices drop as low as $9,000 before recently
recovering to about $21,000 in August (although prices have now pulled
back somewhat from the August highs.)
Nickel pig iron
An important development in the nickel industry in recent years has been
the emergence of NPI production in China. NPI is produced from low-grade
nickel ore, and this higher-cost production method sits primarily in the
upper quartile of the global supply curve. Therefore, NPI production
makes sense when nickel prices are strong, and this source can add to
global supply when demand surges. NPI production can contribute roughly
200,000 metric tons per year, or roughly 14% of global primary nickel
production. NPI production costs vary depending on ore prices,
electricity and energy costs, and integration with a stainless steel
plant. Estimates for what level of nickel prices "turn on" NPI
production vary widely--Xstrata has stated that lower-cost producers
need prices of only $11,000, while Australian Bureau of Agricultural and
Resource Economics notes prices of $26,000. In other words, this part of
the cost curve seems steep. Speaking in aggregate terms, however, given
recent decreases in input costs, the nickel price necessary to justify
NPI production is probably lower now than it was during the recent
commodities boom.
Stainless steel
Changes within the stainless steel market have been a key dynamic for
nickel demand. Given $50,000-plus nickel prices, it made sense for
stainless steel manufacturers to substitute away from
higher-nickel-content stainless. Indeed, in recent years
higher-nickel-content stainless has lost share to lower- and
no-nickel-content stainless. For example, the market share of "200
series" stainless (a lower-nickel-content variety) increased from
roughly 5% in 2001 to over 10% in 2007, according to BHP Billiton and
the International Stainless Steel Forum, while the market share of "400
series" stainless (no nickel) increased from about 25% to approximately
30%. This came at the expense of "300 series" stainless, the variety
with a higher nickel content, where market share deteriorated from over
70% in 2001 to less than 60% in 2007.
Production cuts
Given weak demand and subsequent collapse in prices, nickel producers
responded in the last year with substantial production cuts to attempt
to bring the market back into balance. Xstrata estimates that production
cuts and disruptions (such as strikes) have amounted to over 20% of
global capacity. While these production cuts are necessary to balance
supply and demand, some represent idle capacity that could be brought
online as nickel prices rise.
Conclusion
We believe two important changes have occurred since dynamics in the
nickel market brought about prices of nearly $55,000 per metric ton.
High prices taught stainless steel manufacturers to use less nickel,
which could have permanent implications for demand. In addition, China
had the incentive and the means to ramp up NPI production, which now
represents a swing source of supply. In combination, we think that these
shifts have created pressure release valves that could limit the upside
to nickel prices in the future when the supply/demand balance begins to
tighten.
