Financial cycles: credit, assets, systemic risk
Financial cycles describe fluctuations in credit activity, asset prices, and financial leverage in the economy. Unlike traditional business cycles, which are measured by changes in GDP, financial cycles have different amplitude, duration, and characteristics. Understanding the interaction between financial and business cycles is critically important for assessing systemic risks and investment positioning.
Characteristics of financial cycles
Studies by the Bank for International Settlements (BIS) have identified key characteristics of financial cycles. They are significantly longer than business cycles—the average duration is 15-20 years compared to 8-10 years for business cycles. The amplitude of financial cycles is substantially greater—credit booms and busts amount to tens of percentage points. Financial cycles are measured by composite indicators including: the ratio of credit to the private sector to GDP, credit growth rates, real estate prices, corporate bond spreads, and leverage ratios in the financial sector.
The peaks of financial cycles often precede financial crises. The global financial crisis of 2008 occurred near the peak of the financial cycle in most developed countries. Similarly, the Asian crisis of 1997 followed a credit boom in the region.
Mechanisms of the financial cycle
Procyclical lending amplifies fluctuations. During economic upswings, banks are eager to expand lending—collateral valuations rise, defaults are rare, and competition pushes towards loosening standards. Credit growth supports demand and asset prices, creating positive feedback. During downturns, the process reverses. Falling asset prices devalue collateral, defaults and reserves rise, and banks tighten lending. The contraction of credit intensifies the economic downturn and further price declines—negative feedback.
The financial accelerator (Bernanke, Gertler) formalizes this mechanism. The net worth of borrowers (assets minus liabilities) determines their ability to obtain credit. Economic shocks affect net worth, changing credit availability and amplifying the initial shock.
Interaction with the business cycle
Financial and business cycles are not always synchronized. A recession may occur without a financial crisis (an ordinary cyclical recession), and a credit boom may happen without obvious economic overheating. However, the coincidence of peaks creates an especially dangerous situation. Recessions that coincide with financial crises are significantly deeper and longer than ordinary recessions. Research shows that GDP falls on average by 5-6% during financial crises compared to 2-3% in ordinary recessions. Recovery takes 5-7 years versus 2-3 years. This is explained by the necessity for deleveraging—households and companies are forced to reduce debt, which suppresses consumption and investment even after the recession ends. Balance-sheet recessions require time to clean up balance sheets.
Macroprudential policy
Awareness of the role of financial cycles has led to the development of macroprudential policy—instruments aimed at limiting systemic risk and smoothing financial cycles. Unlike microprudential supervision of individual institutions, macroprudential policy focuses on the system as a whole.
Countercyclical capital buffers require banks to build up additional capital during credit booms. This constrains credit growth in good times and creates a cushion for bad times. Basel III introduced such buffers as a standard tool.
LTV (loan-to-value) and DTI (debt-to-income) limits for mortgage lending directly restrain credit booms in the real estate market. Many countries (Canada, New Zealand, Scandinavian countries) actively use these instruments.
Investment implications
Positioning within the financial cycle determines strategic decisions. In the early phase of credit expansion, banks and financial companies, cyclical sectors, and real estate markets are potential beneficiaries. In the late boom phase—it is time for caution and risk reduction.
Credit cycle indicators serve as warning signals. BIS publishes the “credit-to-GDP gap”—the deviation of the credit-to-GDP ratio from the long-term trend. High values (>10%) have historically preceded financial crises.
Geographical diversification helps manage the risk of financial cycles. Different countries are in different phases of the financial cycle. Investments in countries at early stages of credit expansion can offset risks in countries near the peak.
