We augment a simple inventory model with new features of the post-crisis regulations to offer new predictions on the effects of post-crisis regulations on the over-the-counter markets. First, the increased capital requirements of Basel III lead to an overall increase in order rejection rates of large orders. Second, and more importantly, the effects on order rejection rates depend on the risk weights used in calculating risk-weighted assets (RWAs). More specifically, the increase in order rejection rates is more severe for assets with higher risk weights, but less severe for assets with lower risk weights. In fact, for the cases of the lowest risk weights, simulations suggest that we may even see a decrease in order rejection rate. Third, the price impact of assets with higher risk weights increases, while the price impact of assets with lower risk weight decreases in the post-regulation period. Overall, our paper points to an important unintended consequence of the post-crisis regulations—the re-distribution of liquidity among assets with different risk weights assigned to them.

The credit default swap (CDS) Big Bang introduced 2 standard coupons for CDS trading. We exploit the setting of the 2 standard coupons as a natural experiment to quantify the components of the bid–ask spreads in over-the-counter markets. We find that a significant portion of the difference in the bid–ask spread between the 2 coupons is explained by the difference in funding costs. Furthermore, search intensity also explains the variation in the difference in bid–ask spread. The liquidity typically concentrates on one of the standard coupons and can suddenly switch to the other coupon. Using the sudden switch of the primary coupon, we provide further evidence to support the predictions of search-based liquidity models.

The sovereign CDS market has developed rapidly for two decades and currently has a gross notional amount of more than a trillion dollars. We document a strong momentum effect in this market, which cannot be explained by a large set of risk factors. These momentum returns are positively skewed and higher during recessions. Consistent with the interpretation that this momentum effect is due to investors’ initial underreaction to sovereign credit information followed by corrections, our evidence shows that the momentum returns tend to be higher during the months surrounding announcements of credit rating or outlook changes of the underlying countries.

This paper examines how political connections shape media bias and contribute to regulatory noncompliance in China's capital markets. Using a large sample of news articles on publicly listed non-state-owned enterprises (non-SOEs), we find that politically connected firms receive significantly more favorable media coverage than their unconnected peers. A difference-in-differences analysis exploiting a regulatory shock—China's Rule 18 anti-corruption regulation—that forced politically connected directors to resign confirms the link between political ties and biased reporting. Around corporate scandals, politically connected firms face softer media scrutiny, weakening reputational penalties. Critically, we show that this media shielding effect increases the likelihood of repeated regulatory violations. These findings highlight the social costs of the “scandal-covering” role of political connections, which not only distort the information environment but also undermine regulatory deterrence and market discipline.

We use the advent of new credit default swap (CDS) trading conventions in April 2009—the CDS Big Bang—to study how a shock to funding liquidity impacts market liquidity. After the Big Bang, traders are required to pay upfront fees to execute CDS transactions, with the size of the fees depending on the level of CDS spreads. While CDS bid-ask spreads decline in aggregate after the Big Bang, they do so less for contracts that require larger fees. Furthermore, the funding effect is stronger for smaller and riskier firms and for noncentrally cleared contracts. The effect also becomes stronger after Deutsche Bank's exit.
