In recent years, mergers, acquisitions and organic growth have meant that some of the largest and most complex financial groups have come to transcend national boundaries and traditionally defined business-lines. As a result, they have become a potential channel for the cross-border and cross-market transmission of financial shocks. This paper analyses the degree of comovement in the equity prices of a selected group of large complex financial institutions (LCFIs), and assesses the extent to which movements are driven by common factors. A relatively high degree of commonality is found for most LCFIs although there are still noticeable divisions between sub-groups of LCFIs, both according to geography and to a lesser extent primary business-line.

We study the cross-section of returns on FX options sorting currencies based on implied volatilities (IVs). Long straddle positions in currencies with low (high) IVs perform well (poorly). A long low IV-short high IV strategy produces large average returns after transaction costs. Total volatility matters rather than any component or transformation of volatility. The returns are distinct from those in the literature on foreign exchange returns or equity option returns and cannot be explained convincingly by standard risk factors. We argue cross-sectional differences in hedging demand combined with limits to arbitrage contribute to mispricing in FX options.

In this paper, we study credit risk transfer (CRT) in an economy with endogenous financing (by both banks and non-bank institutions). Our analysis suggests that the incentive of banks to transfer credit risk is aligned with the regulatory objective of improving stability, and so the recent development of credit derivative instruments is to be welcomed. Moreover, we find the transfer of credit risk from banks to non-banks to be more beneficial than CRT within the banking sector. Intuitively, this is because it allows for the shedding of aggregate risk which must otherwise remain within the relatively more fragile banking sector. Therefore, regulators should act to maximize the benefits from CRT by encouraging the development of instruments favorable to the cross-sectoral transfer of aggregate credit risk (including basket credit derivatives such as collateralized debt obligations). Finally, we derive the optimal regulatory stance for banks relative to non-bank financial institutions. We show that a level playing field approach is sub-optimal. Regulatory stances should be set to actively encourage cross-sector CRT, first because of the higher fragility of the banking sector and second to induce banks to incur the costs of CRT which otherwise lead them to undertake an insufficient amount of CRT.

We study the effects that the ban on short sales of shares in financial firms introduced in late 2008 and removed early 2009 had on the microstructure and the quality of UK equity markets. We show that the ban did nothing to affect order flows: financial stocks were being more aggressively sold off than their peers pre-ban and this situation persisted through the ban period. Trading volume in financials was massively reduced, however. The ban decimated order book liquidity for financials. The deterioration was symmetric, affecting the limit buy and limit sell side of the order book equally. Finally we show that, through the period of the ban, markets for financial stocks were substantially less efficient and that the role of the trading process in aiding price discovery was greatly reduced. The effects identified above were largely reversed once the ban was lifted. The persistence of the deterioration in market quality and liquidity though the relatively long-lasting UK ban on short selling suggests that other major market developments such as the TARP program were not responsible since these were concentrated in the early half of the ban. We thus argue that the short selling ban was responsible for detrimental effects on the quality of UK equity markets and that, far from being stabilising, the ban exacerbated problems in valuing UK financial stocks.

Using an expanded version of the purchasing-power-parity condition we construct simultaneous equation models for three key exchange rates which incorporate meaningful long-run equilibrium relationships and complex short-run dynamics. We show that fully dynamic out-of-sample forecasts from these models are capable of significantly outperforming those of a random walk model over horizons as short as 3 months, and that they are also more accurate than the vast majority of professional forecasts.

We test the theoretical equivalence of credit default swap (CDS) prices and credit spreads derived by Duffie (1999) , finding support for the parity relation as an equilibrium condition. We also find two forms of deviation from parity. First, for three firms, CDS prices are substantially higher than credit spreads for long periods of time, arising from combinations of imperfections in the contract specification of CDSs and measurement errors in computing the credit spread. Second, we find short‐lived deviations from parity for all other companies due to a lead for CDS prices over credit spreads in the price discovery process.

We examine how gender differences in investment risk tolerance, knowledge, confidence and portfolio cash allocations relate to the gender mix of investors and financial advisors among a sample of wealthy individuals in the UK. Our results demonstrate that gender effects are more nuanced than previously assumed. First, while even wealthy women consider themselves more conservative and allocate a higher proportion of their investable assets to cash than men, previous findings of lower investment knowledge and confidence do not extend to our sample. Second, having an advisor matters. Advised investors perceive themselves to have a higher risk tolerance and invest 10.6%-points more than self-directed investors. Finally, the investor-advisor gender combination matters, but only for female investors. Women with male advisors are more risk averse, feel less knowledgeable and less confident about their investment decisions. They also invest 11%-points less than women with female advisors. Indeed, female investors advised by women report the highest risk tolerance and make the lowest portfolio allocation to risk-free assets across the full sample, including men.

This study exploits a new long-run data set of daily bid and offered exchange rates in spot and forward markets from 1919 to the present to analyze carry returns in fixed and floating currency regimes. We first find that outsized carry returns occur exclusively in the floating regime, being zero in the fixed regime. Second, we show that fixed-to-floating regime shifts are associated with negative returns to a carry strategy implemented only on floating currencies, robust to the inclusion of volatility risks. These shifts are typically characterized by global flight-to-safety events that represent bad times for carry traders.
