  3. Starting to invest early can lead to huge benefits, even if you invest less. Time in the market can be more powerful than investing more money later.

Slippery Slope: An Interview with Citigroup's Edward Morse

The Octavian Report • 0 implied HN points • 23 Dec 25
đź’° Finance Investing
  1. Since 2014, U.S. shale plus oil sands and deepwater supply made oil much more responsive and eroded OPEC’s price power. That structural change likely keeps oil in a roughly $40–$65 per barrel range in the medium term.
  2. Renewables, natural gas, and electric vehicles are slowly eating into oil’s remaining strongholds (transport and petrochemicals), so fossil fuels’ share of energy should shrink long term and petrostates face capped revenues and greater fiscal stress.
  3. Improved productivity and cost declines have opened real opportunities in unconventional and deepwater plays (e.g., Argentina’s Vaca Muerta, Mexico, North Sea, Gulf of Mexico, Brazil), though geopolitical shocks like a Saudi–Iran conflict could still cause sharp, but unlikely, price spikes.

  1. Volatility is at historic lows because lots of investors are selling volatility, which suppresses price swings now but makes the market fragile and likely to see a much bigger spike if a breakout happens.
  2. Credit and equity markets can diverge for months, so companies whose stocks have collapsed sometimes still have debt trading high, creating both hidden risk and capital‑structure arbitrage opportunities.
  3. Discounted closed‑end funds and niche strategies like capital‑structure and volatility arbitrage look especially attractive right now, since active managers can earn yield and profit from mispricings that most institutions overlook.

  3. Instead of trying to time the market, focus on resilience: diversify new savings into bonds, international stocks, or gold, and make sure you could survive drawing from investments during a long downturn.
