Emerging Market Liquidity and Crises

Abstract

Alors que la sagesse conventionnelle soutient que les marchés ferment en période de crise, les vendeurs ayant du mal à trouver des acheteurs, nous constatons que les marchés continuent de fonctionner pendant les turbulences financières, même dans les économies émergentes étroites et volatiles. Des études d'événements simples indiquent que le volume des transactions et les coûts de transaction augmentent en période de crise. Les prix changent davantage avec chaque dollar négocié (ce qui augmente la mesure de l'illiquidité Amihud) et les écarts entre les cours acheteur et vendeur s'élargissent. Plus généralement, les estimations économétriques montrent que les grandes baisses de prix, typiques des crises, sont associées à une activité commerciale plus élevée et à une augmentation des coûts de négociation, l'activité commerciale ne diminuant que plus tard à mesure que les crises progressent. Ainsi, bien que l'activité de négociation ait tendance à être négativement liée aux coûts de négociation pendant les périodes de tranquillité (et entre les titres), cette relation semble se briser pendant les crises. Ces résultats sont cohérents avec la littérature analytique sur le rééquilibrage des portefeuilles par des agents hétérogènes en temps de crise.

Mientras que la sabiduría convencional sostiene que los mercados se cierran durante las crisis, con los vendedores luchando por encontrar compradores, encontramos que los mercados continúan operando durante la agitación financiera, incluso en economías emergentes estrechas y volátiles. Los estudios de eventos simples indican que tanto el volumen de trading como los costes de trading aumentan en tiempos de crisis. Los precios cambian más con cada dólar negociado (empujando la medida de iliquidez de Amihud hacia arriba) y los diferenciales de oferta y demanda se amplían. De manera más general, las estimaciones econométricas muestran que las grandes caídas de precios, típicas de las crisis, se asocian con una mayor actividad comercial y mayores costos comerciales, y la actividad comercial disminuye solo más tarde a medida que avanzan las crisis. Por lo tanto, aunque la actividad de trading tiende a estar relacionada negativamente con los costes de trading durante los momentos de tranquilidad (y en todos los valores), esta relación parece romperse durante las crisis. Estos resultados son consistentes con la literatura analítica sobre el reequilibrio de carteras por agentes heterogéneos en tiempos de crisis.

Whereas conventional wisdom argues that markets shut down during crises, with sellers struggling to find buyers, we find that markets continue to operate during financial turmoil, even in narrow and volatile emerging economies. Simple event studies indicate that both trading volume and trading costs increase in crisis times. Prices change more with each dollar transacted (pushing the Amihud illiquidity measure up) and bid-ask spreads widen. More generally, econometric estimates show that large price downturns, typical of crises, are associated with higher trading activity and increased trading costs, with trading activity declining only later as crises progress. Thus, although trading activity tends to be negatively related to trading costs during tranquil times (and across securities), this relation appears to break down during crises. These results are consistent with the analytical literature on portfolio rebalancing by heterogeneous agents in times of crises.

في حين تجادل الحكمة التقليدية بأن الأسواق تغلق أثناء الأزمات، حيث يكافح البائعون للعثور على مشترين، نجد أن الأسواق تستمر في العمل أثناء الاضطرابات المالية، حتى في الاقتصادات الناشئة الضيقة والمتقلبة. تشير دراسات الأحداث البسيطة إلى أن كل من حجم التداول وتكاليف التداول تزداد في أوقات الأزمات. تتغير الأسعار أكثر مع كل دولار يتم التعامل معه (مما يدفع عدم سيولة أميهود إلى الارتفاع) واتساع فروق الأسعار بين العرض والطلب. بشكل عام، تُظهر تقديرات الاقتصاد القياسي أن الانخفاضات الكبيرة في الأسعار، وهي نموذجية للأزمات، ترتبط بارتفاع نشاط التداول وزيادة تكاليف التداول، مع انخفاض نشاط التداول في وقت لاحق فقط مع تقدم الأزمات. وبالتالي، على الرغم من أن نشاط التداول يميل إلى أن يكون مرتبطًا سلبًا بتكاليف التداول خلال الأوقات الهادئة (وعبر الأوراق المالية)، يبدو أن هذه العلاقة تنهار أثناء الأزمات. تتوافق هذه النتائج مع الأدبيات التحليلية حول إعادة توازن المحفظة من قبل وكلاء غير متجانسين في أوقات الأزمات.
