Yeah swaptions would be nice but it seems like the minimum size is $1mm.
Why not just short-sell treasuries (e.g. TLT)?
Futures and options give you a lot more leverage than short selling. A $100k short position on TLT would be $30k of maintenance margin, compared to $7,400 for UB.
And banks and hedge funds arbitrage futures prices against the underlying asset, so trading futures basically gives you access to institutional interest rates instead of retail margin rates. Right now the rate difference for short selling on IBKR is ~5% for accounts <$100k and 1...
I spent a couple hours looking at different methods to efficiently short long term bonds:
They claim that by specializing the chips for transformer workloads and removing the programmability of GPUs, they can fit an order of magnitude more compute FLOPs on the same size chip, which is plausible. But common wisdom is that LLMs are memory bandwidth limited. Model Bandwidth Utilization in inference workloads is often 60-80%, which would indicate that Nvidia's chips are reasonably well balanced in their ratio of bandwidth to compute, and that here isn't a ton of performance to be gained by just increasing compute. The Sohu chip reportedly has 144GB... (read more)
