Valuation and Liquidity of Fixed Income ETFs

• Fixed income ETF valuations are calculated using daily PCFs combined with estimated bond prices, which is challenging since most bonds don't trade on centralized exchanges or even daily
• Average daily volume is a misleading liquidity metric for fixed income ETFs; true liquidity depends on underlying basket liquidity, number of competitive liquidity providers, and authorized participants who can create/redeem shares
• In Europe, exchange fragmentation makes volume consolidation difficult compared to the US, though the forthcoming consolidated tape should improve transparency for both bond trading (via consolidated tape) and ETF volume assessment

Summary: Valuation and Liquidity of Fixed Income ETFs

Key Points:

Fixed income ETFs provide investors with price transparency, intraday liquidity, and operational simplicity that underlying bond markets lack. However, trading them effectively—especially in large sizes—requires understanding valuation and liquidity nuances specific to bond markets.

Valuation:

Liquidity providers calculate ETF fair values using Portfolio Composition Files (PCFs) published daily by issuers, combined with bond price estimates. Pricing bonds is challenging as most don't trade on centralized exchanges. In the US, TRACE provides post-trade transparency; Europe's data remains fragmented, though a consolidated tape is forthcoming.

Investors have two valuation options: build proprietary systems using PCFs and live bond prices (resource-intensive), or use third-party indicative NAV (iNAV) services (less reliable for investment decisions).

Liquidity Assessment:

Average daily volume (ADV) is commonly misunderstood as the primary liquidity metric, limiting new ETF growth unnecessarily. This problem is worse in Europe due to exchange fragmentation versus the US's consolidated volume data.

Fixed income ETF liquidity is actually created by liquidity providers transacting over-the-counter through primary market creation/redemption. Key liquidity factors include:

• Underlying basket liquidity
• Outstanding amount of underlying securities
• Number of competitive liquidity providers via RFQ
• Number of authorized participants (particularly important in Europe)
• Consolidated ADV including block trades

Market Implications:

Fixed income ETFs are now core portfolio tools used for cash management, benchmark replication, hedging, speculation, and transition management. Investors with deeper understanding of valuation and liquidity mechanisms can execute more efficiently and assess relative value between ETFs, individual bonds, and portfolio trades.
