Core Viewpoint - The upcoming issuance of savings bonds in China is expected to provide better investment returns compared to traditional bank fixed deposits, particularly for investors with a principal of 500,000 yuan [1][11]. Summary by Category Issuance Details - The new batch of savings bonds will be issued from October 10 to 19, with a total national quota of 26 billion yuan, split evenly between 3-year and 5-year bonds [1]. Investment Returns - The interest rates for the four major state-owned banks are 1.25% for 3-year fixed deposits and 1.3% for 5-year fixed deposits. For a principal of 500,000 yuan, the interest earned would be 18,750 yuan for 3 years and 32,500 yuan for 5 years [5]. - In comparison, the previous month's interest rates for savings bonds were 1.63% for 3 years and 1.7% for 5 years, yielding 24,450 yuan and 42,500 yuan respectively for the same principal [5]. - This indicates that the 3-year savings bond offers 5,700 yuan more than the fixed deposit, while the 5-year bond provides an additional 10,000 yuan [5]. Safety Comparison - Savings bonds are backed by national credit, making them safer than fixed deposits in state-owned banks, which are also insured up to 500,000 yuan [7]. Liquidity Analysis - The new savings bonds have a staggered interest calculation, where early redemption before six months yields no interest, while fixed deposits incur a penalty of receiving only the current savings account rate of 0.05% [9]. - This structure may lead to significant interest losses for those needing liquidity [9]. Limitations - The new savings bonds have limited availability, requiring investors to queue at banks for purchase, and they can only be bought at bank counters, not online [9][11]. - Additionally, interest on the bonds only begins to accrue after six months, which may deter some investors [9][11].

链上股票代币化平台在我看来解决的核心场景是避免传统高频交易 & 波段造成的高流水,并且也是目前很多项目方、公链都想尝试的新赛道。昨天晚上 Solana 上的 Moonshot 趁夜上了好几支股票,可见对于代币化股票的重视而这些代币化股票有一项比较大的问题在于安全性,不少人存在对于平台方面的质疑,担心买了股票之后这部分股票资产并非实际映射。这个 Ondo Wall Street 2.0 应该算是一种资产安全性比较强的解法了,Ondo 也已经算是老牌的合规项目方。平台上的代币化股票种类和多样性还是挺丰富,已经有数百支股票可以通过 Ondo 购买首发在以太坊主网上,虽然 gas 比较贵(现在也没那么贵了),但还是增加了更多以太坊生态的应用,也丰富了 Ondo 的生态Ondo Finance (@OndoFinance):1/ Wall Street 2.0 is here.Ondo Global Markets is now live, providing one of the largest-ever selections of tokenized U.S. stocks & ETFs onchain with ...
