The aluminium market service short term outlook (STO) is published monthly and provides a forecast of aluminium supply and demand fundamentals over the next two-years. After an extended period of nominal market surpluses, the global aluminium market looks to be finally moving definitively towards balance over the next 2-3 years. Much will still depend on supply side adjustments in China and how they play out over the near term. Pollution related cutbacks and a clampdown on regulation non-compliance for new capacity are back on the agenda. Unsurprisingly, the LME price has continued to show strength during April trading mostly well above $1900/t and has been the best performing metal on the LME over the past month.
