Group 1: Export Ban Impact - Indonesia's nickel export ban, implemented in 2014, aimed to promote domestic industrialization and increase domestic value-added ratio (DVAR) in downstream industries[4] - The DVAR in the steel-using sector increased by 5.6% from 2011 to 2020, contrasting with an overall DVAR growth of only 1.1% in the economy[17] - The ban led to a higher share of smaller, less efficient firms entering the market, resulting in an overall loss of efficiency in downstream industries[4] Group 2: Market Dynamics - The export ban created a buyer's monopoly in the nickel market, leading to a decrease in domestic nickel prices, which in turn lowered steel prices[16] - Despite increased domestic steel usage, the reliance on imported steel remains significant, indicating limited capacity to produce high-quality steel domestically[19] - The average firm size in the steel-using sector decreased significantly post-ban, with a higher proportion of small new entrants, which contributed to lower overall productivity[17] Group 3: Policy Recommendations - To minimize unintended negative impacts and further advance industrialization, the government should implement complementary policies such as trade liberalization and foreign direct investment (FDI) facilitation[20] - The findings suggest that while the export ban has started to increase domestic value-added, it also incurs unexpected costs that could hinder long-term growth prospects[30] - The study emphasizes the need for comprehensive and effective policy coordination to enhance economic foundations rather than relying solely on export bans[30]

Summary by Sections 1. Introduction - Climate financial risks pose significant challenges to the financial sector, including both physical risks from climate-related disasters and transition risks from moving to a low-carbon economy [22]. 2. Methodology - The report employs a four-step framework for climate transition risk stress testing, including scenario development, macroeconomic modeling, credit risk assessment, and a stress testing model [39][70]. 3. Low-Carbon Transition Scenarios - Three low-carbon transition scenarios are evaluated, with the orderly NDC scenario projected to achieve a 21% reduction in emissions by 2030 compared to the business-as-usual (BAU) scenario [75][80]. 4. Macroeconomic and Sectoral Impacts - The orderly NDC scenario is expected to lead to gradual adoption of carbon taxes, incentivizing low-carbon technologies while causing moderate inflation and slight declines in domestic consumption and exports [14][16]. 5. Impact on the Financial Sector - The banking sector's performance remains robust, with limited increases in non-performing loan (NPL) ratios during orderly transitions, but higher credit risks in sectors like industry and construction during disorderly transitions [16][20]. 6.

Report Industry Investment Rating No relevant information provided. Core Viewpoints - Diversified guarantee mechanisms are crucial for attracting private investment in Brazilian infrastructure projects, and innovative risk mitigation solutions are needed to promote project implementation and create a more attractive investment environment [3] - The franchise law and public - private partnership law have led to significant private participation in Brazilian infrastructure, but there are still issues such as a lack of federal - level PPP projects with public payments and a high local - level project failure rate, highlighting the need for more effective guarantee mechanisms [8][9] - Modernizing public accounting rules, strengthening the monitoring and management of project - related expenditures, and collaborating with MDBs to develop and improve guarantee mechanisms are important steps forward [26][28][30] Summary by Related Content Context of Brazilian Infrastructure Investment - In the 1990s, Brazil reformed to cut public spending and allowed private sector participation in government - managed activities. The Franchise Law (No. 8,897/1995) was established to delegate public services to the private sector [6] - In 2004, Brazil passed Law No. 11,079/2004 to establish public - private partnerships (PPP), allowing public payments to supplement private partners' income in different ways [7] - By 2023, Brazil plans to invest about $905.44 billion in over 4,600 infrastructure projects in the next 30 years, but most PPP projects are signed by local authorities, and the federal government still relies on franchises [8] - After 20 years of the PPP bill implementation, there are no federal - level PPP projects with public payments, and the local - level project failure rate is high, mainly due to financial, regulatory, and planning issues [9] Importance of Guarantees - Diversified guarantee mechanisms are essential for attracting private investment in PPP projects and franchises, providing legal security, reducing perceived risks, and lowering financing costs [10] - Guarantees in PPP projects can mitigate the risks of public entity default or payment delay, protect the interests of franchisees, and enhance investor confidence [12] - Effective guarantees should be liquid, independent of public budgets or political discretion, and free private partners from relying on slow and costly judicial payment mechanisms. Multilateral development bank (MDB) guarantees have added value in this regard [13] Guarantees Stipulated by Brazilian PPP Law - The PPP law provides a detailed list of guarantees, including revenue earmarking, special funds, guarantee insurance, guarantees from international organizations or financial institutions, and guarantee funds or state - owned enterprises [14] - Each type of guarantee has potential advantages and disadvantages. For example, revenue - linked guarantees may be revocable and require court execution, while guarantees from international organizations may have a slow approval process [18] Issues with Public Guarantees - Public guarantees may limit the availability of resources for other projects, as mechanisms like escrow accounts "freeze" public funds, reducing the flexibility and efficiency of public finance allocation [21] - In Brazil, MDB guarantees for PPP projects are only allowed at the local level and are currently classified as credit operations, consuming fiscal space. The limited monitoring of contingent liabilities is a major obstacle to their effective use [22] Forward - Looking Directions - Modernize public accounting rules to "unfreeze" funds. Revise accounting rules to classify MDB guarantees as contingent liabilities rather than immediate debts, but also strengthen the assessment and monitoring of high - risk guarantees [26][27] - Strengthen the monitoring and management of project - related expenditures, especially contingent liabilities. Establish unified guidelines to evaluate and quantify risks and contingent liabilities in PPP contracts, ensuring more accurate accounting and better fiscal risk management [28] - Collaborate with MDBs to develop and improve public guarantee mechanisms. MDB guarantees can enhance the effectiveness and robustness of PPP projects, providing confidence to investors and optimizing resource utilization [30]
