- Fairfax wins nod to acquire IDBI Bank , but faces challenge of shifting its public - sector culture
Fairfax Financial Holdings has cleared the government's hurdle to acquire IDBI Bank, but its bigger challenge lies inside the lender, where unions have pushed back and the culture remains close to a state-run entity. The United Forum of IDBI Officers & Employees “strongly opposes” the sale of a controlling stake to a “foreign entity,” while the government has assured employees their service interests will be protected. Analysts say moving a large unionised workforce to private-sector ways of working will be the hardest part. The Centre is selling a 60.72% stake in IDBI Bank to Fairfax, which holds 40% of CSB Bank; since RBI rules bar owning two banks, Fairfax must either sell that stake or merge CSB into IDBI Bank. IDBI Bank accounts for 1.2% of the banking system's loans and deposits, versus 0.2% for CSB Bank.
- Russia's largest bank Sberbank secures approval to trade crypto
Sberbank, Russia's largest bank, has been added to the Bank of Russia's register of cryptocurrency exchange providers, following its earlier entry into the digital depository register this month. The bank plans to open crypto trading to all clients on Dec. 1 and is already testing BTC, ETH and USDT trades in its app. Domestic crypto payments remain banned, and from July of next year all crypto transactions must go through registered intermediaries, which would effectively shut out peer-to-peer trades settled through Russian bank accounts. Nine organizations are now on the exchange register, including VTB and T-Invest Lab.

The rules apply only to the covered temporary parking points, not to all parking locations in the city, and the Department of Construction will review actual costs and propose price adjustments if needed.

- Bitcoin ETFs just saw their biggest day in a month thanks entirely to BlackRock
U.S. spot bitcoin ETFs took in $526.6 million on Monday, the largest daily net inflow in nearly a month, driven entirely by BlackRock's iShares Bitcoin Trust (IBIT), which pulled in $665.2 million, its biggest daily inflow since Oct. 7 last year, according to SoSoValue data. Fidelity's FBTC lost $83.6 million and Grayscale's GBTC shed $54.9 million, while the remaining funds recorded no net flows. The inflow more than erased last week's $228.5 million of withdrawals, but funds remain about $90.5 million in net outflows for October, according to CoinDesk calculations. Ether funds moved the opposite way, losing $103.3 million in their fourth consecutive session of outflows, with BlackRock's ETHA accounting for $95.4 million of that.
- A Big4 bank cut deposit rates in the morning, then raised them again in the afternoon
VietinBank cut its deposit rates for terms of 6 months and longer on the morning of Oct. 20, then restored them to pre-adjustment levels by the afternoon. Its afternoon rate board showed 3.5% per year for 6 to under 12 months, 5.9% for 12 to under 24 months and 6% for 24 months and longer, versus 3%, 5.4% and 5.5% in the morning. Rates for terms under 6 months stayed unchanged, including 2.1% for 1 to under 3 months and 2.4% for 3 to under 6 months. The move came as banks followed the State Bank of Vietnam's guidance to cut deposit rates by at least 0.5 percentage points for terms of 6 months and longer, and Vietcombank and Agribank were among those reducing rates.
- IVV vs. SPY: Which S&P 500 ETF Is the Better Buy for Long-Term Investors?
The article compares two ETFs that track the S&P 500, iShares Core S&P 500 ETF (IVV) and State Street SPDR S&P 500 ETF (SPY), which have nearly identical holdings. The main difference is the expense ratio: IVV charges 0.03% a year, one-third of SPY's 0.09%, and its distribution yield is about 1.1% versus 1% for SPY. SPY's high liquidity remains valuable for active traders. The article concludes that IVV is the better choice for long-term investors, since lower costs can compound over time.
- Warren Buffett Is Issuing a Stark Warning About the Stock Market. Here's What History Says Comes Next.
Warren Buffett has warned that investors are taking on too much risk, likening the market to 'a church with a casino attached' and saying people have never been in a more gambling mood. The article points to the S&P 500 Shiller CAPE Ratio, which has stayed above 40 since May of this year; historically, the only other time it held above that level for months was during the dot-com bubble, when it peaked around 44 before the bear market began in March 2000. The article notes that 40 is not an automatic trigger for a downturn, and no metric can predict timing. It suggests investors focus on quality stocks with solid fundamentals and be ready to hold them for at least a few years.
- Early Uber Investor Jason Calacanis Predicts Waymo Could Buy Lucid Or Rivian — Calls Its Chinese-Car Optics ‘Really Bad’
Early Uber investor Jason Calacanis predicts Waymo will buy Lucid Group (LCID) or Rivian Automotive (RIVN), arguing that its reliance on Chinese-made Zeekr vehicles creates cost and reputational problems. He says the arrangement is technically not illegal today, but Waymo would need to pay a tariff of over 100%, and it has drawn national-security concerns on Capitol Hill. According to Semafor, Waymo aims to grow its fleet from about 4,000 vehicles to 8,000 by the end of 2026 and 20,000 by the end of 2027, after closing a $5 billion term loan and a $16 billion equity raise this year. Uber has committed to buying at least 35,000 Lucid vehicles, while its Rivian deal starts with 10,000 autonomous R2 SUVs, with rides expected to begin in 2028. Calacanis, who recently bought small stakes in Lucid, Rivian, WeRide (WRD) and Pony.ai (PONY), expects consolidation in the autonomous-driving sector within 24 months.
