I normalised the time series of the past 2 halvings to start at 100 (excl. 2012). This is the first 200 days of the 2016, 2020 and 2024 halving cycles. (Green = 2024, Orange = 2020, Blue = 2016). I think we need to remain patient and wait another 3 months for the supply shock.
WORLD WAKING UP to the fact that a bank deposit is an unsecured loan to a leveraged counterparty, that the FDIC insurance fund only has $128bn, that total deposits in US commercial banks=$17.6 trn, &...here's the big one: that money itself is a confidence game (always has been)🤔

Q3 has started off <0.5 on the CBOE put/call ratio again. Excessive bullishness again? ycharts.com/indicators/cbo…
The BoJ now owns 80% of all ETFs domiciled in Japan. The US is following suit, being a top 5 holder of Corporate Bonds. Central Banks may think they're helping, but they're destroying the financial markets.
