- Abstract
- The functioning of sovereign bond markets is closely intertwined with repo markets, where investors finance long positions and source bonds for short sales. We show, theoretically and empirically, how conditions in the cash bond market fundamentally shape repo rates: When demand for cash bonds exceeds available supply, arbitrageurs, notably hedge funds, step in to bridge the gap by shorting bonds and borrowing them in the repo market. These arbitrage strategies drive a wedge between monetary policy rates and repo rates, generating “specialness”. To investigate the drivers of investors’ demand for repo contracts, we obtain regulatory data covering the entire universe of repos backed by German sovereign bonds. We identify the ultimate borrowers and lenders of securities and estimate their demand and supply elasticities for the repo market. Supply, dominated by the public sector, accounts for 87% of the aggregate elasticity. Demand, driven mainly by hedge funds, is strongly inelastic: a 10% increase in borrowing costs reduces their borrowing by only 1%. Despite being among the most price-elastic investors in cash bond markets, hedge funds are inelastic in repo markets because their bond borrowing bridges the preferred-habitat demand in the cash bond market: their elasticity is inherited from their cash-market counterparties rather than being a primitive. As a result, repo rate specialness emerges as the equilibrium price reflecting demand pressures in the cash bond market, of which collateral scarcity from central bank purchases is a special case. Consequently, the same cash bond market imbalances affect both the pricing of safe assets and repos, two markets that are of crucial importance for the transmission of monetary policy.

- Abstract
- Central clearing counterparties (CCPs) were established to mitigate default losses resulting from counterparty risk in derivatives markets. In a parsimonious model, we show that clearing benefits are distributed unevenly across market participants. Loss sharing rules determine who wins or loses from clearing. Current rules disproportionately benefit market participants with flat portfolios. Instead, those with directional portfolios are relatively worse off, consistent with their reluctance to voluntarily use central clearing. Alternative loss sharing rules can address cross-sectional disparities in clearing benefits. However, we show that CCPs may favor current rules to maximize fee income, with externalities on clearing participation.

- Abstract
- Using a novel regulatory dataset of fully identified derivatives transactions, this paper provides the first comprehensive analysis of the structure of the euro area interest rate swap (IRS) market after the start of the mandatory clearing obligation. Our dataset contains 1.7 million bilateral IRS transactions of banks and non-banks. Our key results are as follows: 1) The euro area IRS market is highly standardised and concentrated around the group of the G16 Dealers but also around a significant group of core ”intermediaries" (and major CCPs). 2) Banks are active in all segments of the IRS euro market, whereas non-banks are often specialised. 3) When using relative net exposures as a proxy for the “flow of risk" in the IRS market, we find that risk absorption takes place in the core as well as the periphery of the network. 4) Among the Basel III capital and liquidity ratios, the leverage ratio plays a key role in determining a bank's IRS trading activity. 5) Also, after mandatory central clearing, there is still a large dispersion in IRS transaction prices, which is partly determined by bank characteristics, such as the leverage ratio.
