大商所调整铁矿石期货合约质量标准

2017-09-14 09:47:37   中国经济网

提高期货价格代表性 贴近市场服务产业

引言

9月13日,大商所发布《关于修改铁矿石期货合约质量标准的通知》称,根据我国当前铁矿石现货市场变化,对交割标准品以及替代品的相关指标和升贴水进行调整,调整后的规则自铁矿石1809合约起施行。“新标准鼓励市场接受度好、供应量稳定的主流矿种进入交割范围,以改善期货价格代表性和稳定性,让企业更放心地参与期货市场。”大商所相关负责人如是说。

高低品矿现货价差扩大 影响期货价格代表性

自2016年下半年以来,钢铁行业持续推进供给侧结构性改革,钢材现货市场供应紧张。为扩大钢材产量,钢厂更倾向于采用含铁量更高、硅铝含量更低、生产铁水效率更高的高品矿。与下游钢材市场变化相对应的是,近年来国内市场流通的铁矿石品种明显增多,一些硅铝杂质含量高、市场流通量小的非主流矿种进入现货市场。这些非主流矿既不满足当前国内钢厂的原料策略,也不符合国家环保政策和产业结构调整导向,还直接影响下游贸易商或钢厂的接货预期。

大商所相关负责人表示,上述供需两端变化导致非主流矿与主流矿间价差不断扩大,原有的期货固定升贴水价差无法覆盖目前现货价差,期货最便利交割品发生改变。这影响了期货市场价格发现和套期保值功能发挥,也加大了买方客户使用和销售难度。在此背景下,市场各方呼吁对铁矿石期货交割质量标准进行调整。

经过多轮论证 制定贴近市场的交割质量新标准

为做好此次交割质量标准调整工作,大商所对19个矿种、380个指标样本进行了详细统计,通过深入研究和反复论证,制定了贴近现货市场的铁矿石交割质量新标准。根据此次通知,新标准分别对交割标准品以及替代品相关标准和升贴水进行调整,严格规范了硅、铝、硫及有害微量元素的允许范围,扩大了对硅、铝、硫的扣罚力度,对硅、铝等影响较大的指标实施梯度升贴水,并对粒度指标进行相关调整。

在具体指标调整上,一是收严二氧化硅含量、三氧化二铝含量的允许范围。据介绍,二氧化硅和三氧化二铝是铁矿石中脉石的主要成分,脉石含量越少、矿石品位越高,越有利于降低焦比、提高产量和炉况顺行。因此,限制矿石的硅铝标准符合钢厂当前的炉料标准。经统计测算,99%以上研究样本的硅铝总量、二氧化硅含量和三氧化二铝含量分别在8.5%以下、6.5%以下和3.5%以下,因此,此次调整将替代品“硅+铝”指标上限由10.0%下调为8.5%。同时,考虑到单硅、单铝指标过高会影响钢厂的生产利润。因此,大商所又分别对单硅、单铝含量分别增加了上限要求,规定二氧化硅、三氧化二铝含量分别不超过6.5%和3.5%。
