Perpetual Futures

Question A:

The introduction of perpetual futures on assets that are otherwise difficult to trade, such as shares in privately held companies, will substantially improve price discovery for those assets.

Responses weighted by each expert's confidence

The introduction of perpetual futures with much laxer leverage limits than for conventional futures will substantially increase the risks of financial instability.

Responses weighted by each expert's confidence

Question C:

The benefits of allowing futures to trade 24 hours a day, seven days a week outweigh the additional risks associated with continuous trading.

How do you do perpetual futures on companies that don't have well functioning markets? Perpetual futures might be useful as ways to put on long term short positions. Otherwise, I think regular trading does a good job of price discovery!

Not hard to improve on private-market price discovery., Perpetual futures can aggregate and disseminate privately held information.

I disagree with "substantially". There may be some benefit given both optimists and pessimists can trade perps. However, the problem is that there is no spot market and arbitrage is difficult. Perps will be a noisy sentiment signal for private assets not a substantial improvement

In other cases where there are no firm quotes on which to base the pricing, this does not always seem to hold. It will be interesting to watch.

Since there isn't an underlying asset, arbitrage won't work to bring future price into alignment with spot price of asset. So price discovery will be limited.

More opportunity to express both bullish and bearish views. But no tight no-arbitrage relationship to underlying when latter is not always traded. Also more room for speculation to overwhelm price discovery.

High leverage and automatic liquidations can trigger cascades. Oct 10, 2025 saw $19b of crypto positions wiped out (but losses stayed in crypto). Expanding to equities and bonds may increase chance of systemic event if very high leverage is allowed.

It's not a clear case. But if not, should markets open only four days a week? Three? A cost of adding hours is increased risk monitoring. Benefits are greater chance for price discovery and risk sharing.

News does not keep exchange hours. Bombing of Iran occurred at 1am Saturday morning. 24-hour mrkts are thinner overnight. Let investors decide to pay that cost or trade at another time. Impt that payment rails are also 24/7 to handle margin calls. Also, AMMs have advantages here
