As a part of my self learning process, I'm trying to gather the list of volatility indices for all major asset classes.
Equity: CBOE VIX (US), VSTOXX (EU), ?? (UK), ?? (JPY)
Commodities: ??
Interest Rates: MOVE index, SRVIX, ??
Credit: ??
FX: DBCVIX, ??
Real Estate: ??
Cash: ??
What are the preferred Volatility indices for these asset classes? Also, are there any caveats one should be aware of while referring to these indices to assess uncertainty?
Edit: I'm not specifically looking for tick by tick data. Rather, I'm searching for vol indices that are generally considered benchmarks, such as the VIX in equities. I was surprised to not find such vol indices for other asset classes as easily as for equities.
