  中国人民银行授权全国银行间同业拆借中心公布,2025年4月21日贷款市场报价利率(LPR)为1年期LPR为3.1%,5年期以上LPR为3.6%,均较上期维持不变。这是LPR连续六个月“按兵不动”。

  综合业内分析来看,4月LPR报价保持不变主要有三点原因,一是作为LPR的定价锚,7天期逆回购利率保持稳定;二是银行净息差仍处在低位,商业银行缺乏下调LPR报价加点的动力;三是一季度经济延续企稳回升态势,短期降息的迫切性不强。

  4月16日,国家统计局发布数据,初步核算,一季度国内生产总值318758亿元,按不变价格计算,同比增长5.4%,比上年四季度环比增长1.2%;4月13日,中国人民银行罕见于周末发布一季度金融数据,2025年一季度社会融资规模增量累计达到15.18万亿元,比上年同期多2.37万亿元;其中,对实体经济发放的人民币贷款增加9.7万亿元,同比多增5862亿元,双双超过市场预期。

  4月中旬,有权威人士告诉记者,当前世界政治经济格局正在经历深刻变化,不确定性影响加大,贸易保护主义抬头,对我国经济的外溢影响也需要观察。我国宏观政策还有空间和余力,将根据形势需要和外部影响动态调整,加强逆周期调节。

  招联首席研究员、上海金融与发展实验室副主任董希淼解读称,从近期公布的经济金融数据来看,降低利率短期不具有紧迫性。从利率本身看,目前无论是新发放的企业贷款还是住房贷款,利率均较上年明显下降,处于历史低位。因此,短期内LPR下行的可能性降低,而降准的必要性更大。

  董希淼预计,二季度央行将实施全面降准0.5个百分点,进一步传递出提振投资者信心、维护资本市场稳定的明确信号。降准可释放长期稳定的低成本资金,有助于进一步降低银行资金成本,推动银行更好地服务实体经济,促进经济高质量发展,为应对外部冲击、稳定资产价格等奠定更加坚实的基础。

  财政和货币政策将打好“组合拳”

  4月政治局会议召开在即,面对更加复杂严峻的外部环境,市场对于新一轮增量政策抱有高度期待。国盛证券首席经济学家熊园表示,虽然一季度经济偏强、GDP同比增速高达5.4%,但基于CPI、PPI等指标看,需求偏弱的特征未见实质改观,再考虑到二季度起关税冲击将逐步显现、亟待政策加码,近期高层也多次表态要将推出新的增量政策。

  例如,4月9日,国务院总理李强主持召开经济形势专家和企业家座谈会,并提到根据形势需要及时推出新的增量政策;又如,4月17日,李强在主持国务院第十三次专题学习时表示,要讲究政策时机,在一些关键的时间窗口,推动各方面政策措施早出手、快出手,对预期形成积极影响。

  中诚信国际研究院院长袁海霞预计,未来财政政策可能从三方面发力:一是根据实际情况进一步加大中央政府财政发力的力度,超长期特别国债的额度可能会有所提升,“两重”“两新”的支持范围也可能进一步扩大;二是可以根据财政发力的力度或者外部形势的变化设立外贸稳定基金,对受外部冲击的行业、企业进行必要的支持;三是加快发行和使用政府债券的节奏和力度,更好地服务实体经济的发展。

  至于货币政策,袁海霞提到,央行去年以来多次提到“择机降准降息”,未来“择机”可能需要考虑三个方面:一是经济基本面的动态变化;二是外部环境的变化,尤其是关税博弈的进展;三是综合考虑对汇率、利率等的影响。

  袁海霞认为,未来货币政策可能会配合财政政策、配合政府债券发行的力度,进行适时的降准或者结构性降息,以对冲政府债券发行对市场流动性的影响。考虑到我国金融机构存款准备金率平均为6.6%,未来降准还是有比较大的空间的,二、三季度可能会有一到两次的降准。另外,中期借贷便利到期的时点主要集中到年末,届时央行可能更多地会采用买断式逆回购去对冲对流动性的影响。

  袁海霞还指出,从降低实体经济的融资成本的角度来讲,结构性的降息大概率今年也会发生。全面降息也是有一定的空间和必要性的,但落地的前提是要解决好非银资金的空转问题以及对银行净息差的影响。

  中国银河证券首席经济学家章俊认为,25BP—50BP降准很有可能在4月政治局会议前后落地,以进一步支持信贷扩张,并节约银行成本,缓解净息差压力;20BP左右的降息可能在美联储再次开启降息进一步确认之后落地,大概率在5月或6月。章俊还称,如果更加兼顾汇率稳定,央行也可能采取不一样的“降息”,即保持政策利率不变,单独引导5年期LPR下行,实现降低融资成本。

  “此外,央行还有可能聚焦外贸、消费和科技创设新的结构性货币政策工具,或对现有的工具进一步优化;同时,调降部分结构性货币政策工具的资金利率,引导信贷投向,以降低企业融资成本。”章俊如是说。

  提振消费、稳定股市楼市仍是关键

  对于降准降息预期,野村中国首席经济学家陆挺近日在媒体交流会上表示,央行现在提供流动性的方式有很多,比如二级市场购买国债、买断式回购等。在陆挺看来,虽然二季度可能降准降息,但更应关注的是财政政策的精准发力。 

  陆挺认为,当务之急是增加一些中央政府的财政支出、加快已有的债务融资框架额度里面的拨付和支出,尤其是在刺激消费和稳定房地产方面可以做更多的事情。

  对于提振消费,陆挺提出了两方面建议:一是考虑耐用品消费之外的消费刺激,尤其是旅游、酒店、餐饮等服务行业,在这方面有一定的潜力;二是借此机会下决心去改革社保体系,因为提高消费能力和消费意愿的关键在于完善社会福利体系。对于后者,陆挺进一步指出,应逐步缩小城乡居民与职工社保体系的差距,将城乡居民纳入职工社保体系;将失业大学生纳入失业保险体系;进一步提高1.7亿农村老人的养老金收入,等等。

  在稳定房地产方面,陆挺认为,虽然部分特定区域,如发达城市、沿海地区的楼市,出现局部复苏迹象,但全国范围内的房地产市场企稳复苏还未出现。对此,陆挺建议,从开发商角度,要让市场继续出清,不能让债务不停滚动;同时,加大保交房力度,这实际上也是对开发商的支持,此外还可以进行一定的收储。

  4月18日,李强主持召开国务院常务会议,研究稳就业稳经济推动高质量发展的若干举措。会议强调,面对复杂严峻的外部环境,要深入贯彻中央经济工作会议精神,锚定经济社会发展目标,加大逆周期调节力度,着力稳就业、稳外贸、促消费、扩内需,并明确提出“持续稳定股市”和“持续推动房地产市场平稳健康发展”两大重点任务。相关举措将直达企业和群众,确保政策高效落地见效。

  值得注意的是,本次国常会将“持续稳定股市”放在“推动房地产市场平稳健康发展”之前,顺序较去年12月中央政治局会议与2025年政府工作报告中先楼市后股市的说法有所调整。

  陆挺在上述媒体交流会上表示,近期央行宣布必要时向中央汇金公司提供充足的再贷款支持,这一政策对于稳定股市非常重要。央行行长潘功胜3月在十四届全国人大三次会议经济主题记者会上也表示,用好支持资本市场的两项货币政策工具,与证监会探索常态化的制度安排,支持资本市场稳定发展。

据媒体报道,今日一架待交付波音飞机从舟山飞回美国,这背后的原因在于,受美国所谓“对等关税”影响,国内航司开始暂停接收波音飞机。

与此同时,国产大飞机C919在近期先后完成东北地区首飞及东南亚航线执飞,并且中越、中马联合声明提及引进和运营中国商用飞机,国产大飞机国内及海外市场需求将持续释放。

在上述背景下,有机构分析,国产大飞机年产能预计2027年将达150架,随着产能提升与市场扩张,国产大飞机产业链的细分领域也将迎来新的发展机遇。

:C919航电连接器市占率55%,耐200℃极端环境,插拔寿命10万次(竞品3倍)

亮点

:新能源车高压连接器市占率25%,特斯拉ModelY核心供应商。

江航装备

优势

:C919氧气系统、惰性化防护系统独家供应商,军用技术转化民用成本降低30%

亮点

:机载油箱惰性化系统故障率低于0.0001次/飞行小时。

产业链发展驱动因素

政策支持

:国产飞机替代率目标60%+,关税倒逼供应链本土化

产能扩张

:C919年产能2027年或达150架,带动全产业链需求

技术突破

:第三代铝锂合金、CJ-1000A发动机等核心技术国产化

国际化

:C919获东南亚、欧洲适航认证,海外订单占比突破15%

风险提示:适航认证进度、技术迭代风险(如陶瓷基复合材料替代)、地缘政治限制关键材料出口
