It is important to note that PCA does not expect growth in cement consumption will be shared evenly across the United States. The Great Lakes, Northeast and mid-Atlantic states, for example, face meager growth conditions, and in some cases outright market contraction. In contrast, markets in the southern, western and mountain regions are expected to achieve somewhat stronger growth rates. The differential in regional growth rates reflects the relative strength of the regional economies as well as each state's unique exposure to declines in residential consumption.

Market conditions

To date, supply has far outstripped potential demand growth during 2006. Tight market conditions that characterized the cement market during the past two years have been dramatically reduced or eliminated. According to the PCA's recent market survey, only two states reflect tight market conditions — compared to more than 30 states in 2004 and 2005.

The reduction in market tightness is accrued to dramatic growth in import volume recorded thus far in 2006 — now running at a 42-million-metric-tonne annual rate. Compared to 2005's record import level of 33.6 million metric tonnes, import volumes are running more than 8 million metric tonnes ahead of 2005. The current import rate implies a supply overhang of more than 5 million metric tonnes.

PCA does not believe the gains in import volume can be sustained. The impressive import gains recorded throughout 2005 and into the first five months of 2006 correlate with favorable global shipping conditions. From the first quarter of 2005 through the first quarter of 2006, Asian freight rates recorded an average decline of 18 percent compared to year-earlier levels.

On the heels of resurging economic growth in China (11.5 percent real GDP growth), tight shipping conditions have recently resurfaced. Reflecting this tightness, freight rates have increased significantly. Handymax dry bulk carrier rates from Asia to the Gulf have increased 89 percent since the beginning of 2006 and now stand at more than $50 per tonne — most of these gains have materialized during the past two months. These increases suggest a more moderate pace of imports through the remainder of 2006 — particularly in the fourth quarter. PCA expects import volume will reach 37.4 million metric tonnes in 2006 and 38.5 million metric tonnes in 2007. As new domestic capacity comes online in 2008 and beyond, import volumes are expected to retreat to 30 million metric tonnes.
