In this Consensus Hong Kong 2026 panel, we dive into the next chapter of on-chain finance: the convergence of DeFi and CeFi — and why crypto prime brokerage may become the infrastructure layer for institutional trading.

From portfolio margin across venues and capital efficiency, to stablecoin balance sheets, oracle risk, and the one threat everyone keeps coming back to… counterparty risk. We break down how prime brokers are bridging siloed liquidity pools, enabling cross-collateral, and rethinking risk management for a world of 24/7 markets.

- DeFi vs CeFi: why convergence is accelerating now

- Prime brokerage in crypto: the "missing layer" for hedge funds

- Portfolio margin across exchanges + on-chain venues (cross-venue risk engines)

- Capital efficiency: moving beyond over-collateralization in DeFi

- Counterparty risk vs smart contract risk — what institutions actually fear

- Off-exchange settlement & custody: what works, what doesn't

- Interest rate models & "dynamic spread": sharing upside with lenders

- Oracles, pricing, liquidation: the two hard problems in DeFi risk management

- The crypto "risk-free rate": SOFR, Treasuries, staking — where does it converge?

- Tokenized markets (RWA): why crypto-native prime brokers may have an edge

As TradFi and DeFi collide, the winners will be the platforms that deliver capital efficiency + transparency + accountability — without blowing up.
