New York City is floating a $500 million second-home tax — and it would hurt industries that support thousands of jobs（MarketWatch Top）
中文摘要：纽约市正在考虑对价值超过500万美元的豪宅征收"第二居所税"（pied-à-terre tax），预计每年可带来5亿美元税收。该政策针对约13,000套非主要住宅，包括公寓、合作公寓和联排别墅。批评者认为，纽约市已背负全美最高的综合税负之一，此举可能加速富裕阶层外迁、抑制投资并阻碍经济增长。支持者则希望通过向超级富豪征税来填补预算缺口，但这也存在风险——一旦高收入纳税人大量迁往低税州，政策效果将大打折扣。
English Summary: New York City is considering a "pied-à-terre" tax surcharge on second homes valued over $5 million, projected to generate $500 million annually. The policy targets approximately 13,000 non-primary residences including condos, co-ops, and townhouses. Critics argue that NYC already bears some of the nation's highest tax burdens, and this measure could accelerate wealthy outmigration, deter investment, and stifle growth.

Iran says Strait of Hormuz is closed again as vessels attempting to cross come under fire（CNBC Finance）
中文摘要：伊朗周六宣布重新关闭霍尔木兹海峡，距其宣布开放该水道不到一天。伊朗革命卫队海军警告称，在美国解除对伊朗港口的封锁之前，任何船只从波斯湾和阿曼海锚地移动或接近霍尔木兹海峡都将被视为"与敌人合作"并可能成为攻击目标。英国海上贸易行动中心报告称，革命卫队的两艘炮艇向一艘穿越海峡的油轮开火，至少还有两艘船只报告在试图通过水道时遭到攻击。印度已就一艘悬挂印度国旗的原油船在穿越海峡时遇袭一事召见伊朗大使。
English Summary: Iran announced Saturday it has reimposed the closure of the Strait of Hormuz less than a day after reopening it. Iran's Revolutionary Guard navy warned that no vessel should move from anchorage in the Persian Gulf and Sea of Oman until the U.S. blockade is lifted, and approaching the strait will be considered cooperation with the enemy. The UK Maritime Trade Operations center reported that two Revolutionary Guard gunboats opened fire on a tanker transiting the strait, with at least two other vessels also reporting coming under fire. India summoned Iran's ambassador after an Indian-flagged vessel carrying crude oil was attacked while attempting to cross the strait.

No escape: U.S.-Iran war, $4 gas, have taken all the fun out of consumer spending（CNBC Finance）
中文摘要：尽管美伊战争持续且汽油价格高达每加仑4美元，美国消费者仍在继续支出，但娱乐和餐饮场所的消费明显回落，对地方经济造成严重冲击。体育赛事和活动组织者观察到，每当有重大新闻（如关税或军事冲突）发布时，活动报名人数就会像股市一样波动——人们会暂停观望。与旅行和体育旅游相关的活动受机票和旅行成本上涨的打击尤为严重。即使是中等规模城市的体育赛事，每位外地参与者也能带来约900至1000美元的附带经济活动（餐饮、住宿、加油等），当消费者选择取消活动或选择离家更近的替代方案时，当地餐馆、酒店和零售商将承受最大的经济损失。
English Summary: Despite the ongoing U.S.-Iran war and $4-per-gallon gas prices, American consumers continue spending, but there's a notable pullback at entertainment and dining venues hitting local economies hard. Event organizers observe that registrations fluctuate like the stock market whenever major news breaks—people adopt a wait-and-see attitude. Events tied to travel and sports tourism are particularly affected by rising airfare and travel costs. Even mid-sized sporting events in smaller cities generate roughly $900-$1,000 in ancillary economic activity per out-of-town participant (meals, lodging, gas). When consumers skip events or choose closer-to-home alternatives, local restaurants, hotels, and retailers bear the brunt of the economic hit.

2 expensive mistakes most retirees make — and how to avoid them（MarketWatch Top）
中文摘要：许多退休人员在退休规划上犯有两个代价高昂的错误：一是过早申领社会保障金，即使等待更长时间可以获得更高的福利；二是支出过于保守，低于其实际承受能力。加州大学欧文分校经济学教授John Duffy与纽约州立大学奥尔巴尼分校副教授Yue Li的研究发现，许多退休人员不愿动用他们的财富，研究人员将他们称为"图坦卡蒙主体"——他们死后仍带着黄金入葬。过早申领社保和资产减持过慢这两个错误相互关联，导致许多老年人未能充分享受退休生活，反而过度储蓄直至生命终结。
English Summary: Many retirees make two costly mistakes in retirement planning: claiming Social Security early despite reduced benefits from waiting, and spending less than they can afford. Research by UC Irvine economics professor John Duffy and SUNY Albany associate professor Yue Li finds that retirees are often unwilling to part with their wealth—the researchers call them "King Tut" subjects who are "buried with their gold." These two mistakes, early Social Security claiming and slow asset decumulation, are interconnected, causing many older adults to underspend throughout retirement and leave excessive savings unutilized at death.

Planning to age in place? Watch out for these hidden costs.（MarketWatch Top）
中文摘要：约77%的50岁以上美国人希望"就地养老"（aging in place），即在自己家中度过晚年，但这一选择往往伴随着被低估的隐性成本。虽然留在家中在情感上具有强大吸引力，但财务后果常被忽视。退休人员可能低估未来的房屋改造、医疗护理、家庭照护和日常维护等费用，这些未预见的开支可能在不知不觉中侵蚀退休储蓄。文章指出，就地养老的实际成本可能远高于预期，对于许多退休人员而言，搬到辅助生活设施或退休社区可能是更经济、更明智的选择。
English Summary: As many as 77% of Americans aged 50 and older prefer to "age in place" in their own homes, but this choice often comes with underestimated hidden costs. While remaining at home has powerful emotional appeal compared to relocating, the financial consequences are frequently overlooked. Retirees may downplay future expenses including home modifications, medical care, in-home caregiving, and ongoing maintenance. These unanticipated costs can quietly erode retirement savings. The article suggests that for many retirees, moving to assisted-living facilities or retirement communities may prove more economical and practical than aging in place.

New Social Security proposal would cap payments for wealthy people now — and many more later on（MarketWatch Top）
中文摘要：华盛顿负责任联邦预算委员会（CRFB）提出一项新的社会保障改革提案：将未来福利上限设定为单身人士每年5万美元、夫妇每年10万美元，无论他们向系统缴纳了多少。该提案预计在未来10年内可削减高达1900亿美元的高收入者福利，若将上限冻结30年，可解决该计划75年预算缺口的一半以上。然而，批评者指出，随着时间推移和通胀累积，这一上限将逐渐影响到更多中等收入退休人员，而不仅仅是当前的富裕阶层。该提案旨在解决社会保障的财政可持续性问题，但具体细节和长期影响仍需仔细审视。
English Summary: The Committee for a Responsible Federal Budget (CRFB) has proposed capping future Social Security payments at $50,000 annually for individuals and $100,000 for couples, regardless of contributions. The proposal could cut an estimated $190 billion from higher earners' benefits over the next decade, and freezing the caps for 30 years would address over half of the program's 75-year shortfall. However, critics note that as inflation accumulates over time, these caps would increasingly affect middle-income retirees, not just the wealthy. While aimed at solving Social Security's fiscal sustainability, the fine print and long-term implications warrant careful examination.

Caregiving has become so crazy expensive that it’s financially devastating to most families（MarketWatch Top）
中文摘要：罗斯福研究所的最新研究显示，长期护理费用已变得如此高昂，以至于对大多数家庭造成毁灭性的财务打击，只有最富有的美国人才能承担得起。研究发现，中产阶级家庭在开始需要长期护理后，平均财富水平下降至原来的42%。随着美国人口老龄化加剧，对长期护理的需求将放大社会中的贫富差距，进一步加深财富不平等。这一现实可能打乱预计高达72.6万亿美元的"大财富转移"——即财富从老一代向年轻继承人转移的进程，使只有最富裕的家庭才能真正从中受益。
English Summary: New research from the Roosevelt Institute shows that long-term care costs have become so prohibitively expensive that they are financially devastating to most families, with only the wealthiest Americans able to bear them. Middle-class households see their wealth drop on average to 42% of original levels after long-term care needs begin. As the U.S. population ages, demand for long-term care will amplify the gap between the haves and have-nots, further deepening wealth inequality. This reality could disrupt the so-called "great wealth transfer"—an estimated $72.6 trillion expected to shift to younger heirs—benefiting only the wealthiest families.

Private credit not only won’t spark a financial crisis — it may be more stable than your bank（MarketWatch Top）
中文摘要：尽管私人信贷市场的赎回压力上升且监管机构日益关注，但评论认为私人信贷比传统银行更能抵御金融危机的冲击。与传统银行用短期、可挤兑的负债为长期、非流动性资产融资不同，私人信贷基金通常拥有80%的股权缓冲和10年的锁定期，这使其不易出现银行那样的资产负债表错配问题。因此，华尔街的"反银行"机构不太可能面临类似雷曼兄弟那样的系统性危机时刻。私人信贷市场的结构特征使其在面对损失时具有更强的韧性，不易将局部损失转化为系统性危机。
English Summary: Despite rising redemption pressures and growing regulatory concern, private credit is argued to be more resilient than traditional banks in withstanding financial shocks. Unlike banks that fund long-term, illiquid assets with short-term, runnable liabilities, private credit funds typically feature 80% equity cushions and 10-year lockups, avoiding the balance-sheet mismatches that make banks fragile. Wall Street's "anti-banks" are therefore unlikely to face a "Lehman moment.

Three things to know about FISA Section 702: Congress passes short-term extension of controversial surveillance program（CNBC Finance）
中文摘要：美国国会周五通过了一项短期法案，将《外国情报监视法》（FISA）第702条款延长至4月30日。该条款原定于周一到期，允许美国政府在无 warrants 的情况下监视境外人员，包括他们与美国公民的通信。支持者认为该计划对保护美国利益至关重要，CIA称该计划帮助挫败了2024年奥地利一场泰勒·斯威夫特演唱会的恐怖袭击计划。然而，许多共和党强硬派和民主党人（如俄勒冈州参议员Ron Wyden）反对无修改的延期，认为需要真正的改革来保护美国人的隐私。特朗普总统呼吁进行18个月的干净延期，认为该计划对军方至关重要。
English Summary: Congress passed a short-term extension Friday of FISA Section 702 through April 30. The provision, set to expire Monday, allows warrantless surveillance of people outside the U.S., including communications with American citizens. Supporters argue it's invaluable for protecting U.S. interests—the CIA cited its role in thwarting a planned 2024 terrorist attack at a Taylor Swift concert in Austria. However, many GOP hardliners and Democrats like Sen. Ron Wyden oppose a clean extension, demanding reforms to protect Americans' privacy. President Trump has called for an 18-month clean extension, deeming the program vital to the military, especially amid operations in Iran.

There's an 'art' to writing AI prompts for personal finance, MIT professor says（CNBC Finance）
中文摘要：麻省理工学院金融工程实验室主任Andrew Lo教授表示，为个人理财撰写有效的AI提示词（prompt）是一门"艺术与科学"。虽然66%使用过生成式AI的美国人表示曾将其用于理财建议，但AI在财务规划方面存在局限性：它擅长提供高层次概述（如投资多样化的重要性），但在精确计算（如税务规划）方面表现不佳，且可能出现"幻觉"给出错误答案。Lo建议用户撰写详细、具体的提示词，要求AI以"仅收费受托人理财顾问"的身份提供建议，并列出关键假设、风险、可能使计划失效的因素以及AI缺失的信息。用户还应通过追问AI"为了生成我想要的答案，我应该问你什么提示词？"来"逆向工程"提示词，以提高未来查询的效率。
English Summary: MIT Professor Andrew Lo says writing effective AI prompts for personal finance is an "art and science." While 66% of Americans who've used generative AI have used it for financial advice, AI has limitations: it's good for high-level overviews (like investment diversification) but struggles with precise calculations (like tax planning) and can "hallucinate" wrong answers. Lo recommends writing detailed, specific prompts that ask AI to act as a "fee-only fiduciary financial advisor" and provide base case strategies, key assumptions, risks, what could invalidate the plan, and what information is missing. Users should also "reverse engineer" prompts by asking AI: "What prompt should I have asked you to generate the answer I was looking for?" to improve future queries.
