college student looking for Rates vol data? too poor for a BBG license?

Theres not a lot of free/public data out there.
Here's 2024 SOFR OIS Swaption Vol Cube Data in daily json format. Also included atm timeseries in a separate dir. Strike offsets are `[-200, -100, -50, -25, -10, 0, 10, 25, 50, 100, 200]` - all in normal vol. I only briefly eyeballed this with what i saw in VCUB but the ONLY use for this data is to mess around. See the README for more info.
If you’re a college student go to the BBG terminal on campus, pull the data you need to excel and then email it to yourself. Obviously static but still good for a personal project
A lot of colleges do not have a BBG terminal, especially the non-targets
Go somewhere that has one then. Another college, library, etc.
Excuse my monkeyness but
i) Where does the SABR Model (and its calibration) mentioned in the Readme come in to this? In my understanding the vols are all normal vol (and thus calculated without SABR whatsoever) but clearly I'm misssing something
ii) What exactly is the difference between this data and your USD_SABR_VOL_CUBE?
hi, this was just a pet project and i dont think DE is actually used in practice (for obvious reasons). maybe some buy side cubes are constructed like this.
the easy answer is that SABR is just a fancy interpolation method. the majority of expiry-tail pairs on the grid aren't traded everyday (just look at SDR flow... sparse is an understatement). in other words, you cant hand mark 300 high 30y30y b/c nothing trades. but you might see some high strike 10y10y; you mark that and SABR helps you build the rest of the cube.
USD_SABR_VOL_CUBE is just more verbose with +/- 300 strikes and more expiry/tails. It is also smoother b/c i shoved it into ql's sabr implementation and ran a calibration again
I think the quants at most banks owns the cube construction process and the traders worry about marking the more liquid parts of the grid.
I see ty ty,
This is off-topic but any chance you have gotten your hands on more Rates/FX sell-side research since last github commit? Esp. anything on linear/non-linear trade recs following tariffs from JPM and the likes?
How in practice would SABR help you mark the 300 high 30y 30y in that case? Would you update the SABR parameters to fit the 10y10y trade and base the 30y30y rom those updated parameters?
