Characteristics of Early Warning Indicators (EWI) Measures

Internally-focused early warning indicators (EWIs) provide insights on the liquidity profile and health of a firm. These measures are crucial in understanding how the firm’s liquidity position could be fluctuating over time and the types of vulnerabilities that may emerge due to business and strategic decisions.

Liquidity risk managers are responsible for identifying and managing underlying liquidity risk factors. They play an integral part in liquidity risk management. Negative trends serve as early indicators that call for an assessment and a possible response by management to mitigate a firm’s exposure to any emerging risk.

Since EWIs aid in managing risk, liquidity risk managers should ensure the quality and timelessness of the data that feeds into EWIs. A relevant and reliable EWI list alerts top management during or ahead of a crisis. Additionally, it complements the overall risk management capabilities of the institution

For example, management should notice when the bank’s liquidity coverage ratio (LCR) has dropped below a specified threshold. Additionally, a dramatic increase in call center volumes may portend a shift in the bank’s liquidity position.

EWIs should be forward-looking, and selected to furnish a mix of business-as-usual (BAU), and stressed environment information. Besides, they should be assessed against limits at predetermined intervals say, daily, weekly, or monthly. Continued deterioration in a single or combined set of EWIs should trigger the firm’s emergency response tools, such as the contingency funding plan.

The Basel Committee on Banking Supervision (BCBS) provided its “Principles of Sound Liquidity Management and Supervision” (Sound Principles) in September 2008, following the global financial crisis of 2007-2008. The following is a non-exhaustive list of EWIs recommended by the BCBS:

  • Rapid asset growth, especially when funded with probable volatile liabilities.
  • Growing concentrations in assets or liabilities.
  • Increases in currency mismatches.
  • Decrement of the weighted average maturity of liabilities.
  • Recurring incidents of positions approaching or breaching internal or regulatory limits.
  • Negative trends associated with a particular product line.
  • Significant deterioration in the bank’s financial condition.
  • Negative publicity Credit rating downgrade.
  • Stock price declines.
  • Rising debt costs.
  • Widening debt/credit-default-swap spreads.
  • Rising wholesale/retail funding costs.
  • Counterparties requesting additional collateral or resisting entering into new transactions.
  • Drop-in credit lines.
  • Increasing retail deposit outflows.
  • Increasing redemptions of CDs before maturity.
  • Difficulty accessing longer-term funding.
  • Difficulty placing short-term liabilities.

EWI Guidelines from Banking Regulators and Supervisors (OCC, BCBS, Federal Reserve)

EWIs must align to and be a natural extension of the enterprise liquidity risk management (LRM) framework. For a bank to adequately capture the banking organization’s exposures, activities, and risks, the Federal Reserve Board Supervisory Letter (FRB SR) 12-7 requires the bank’s LRM framework to be end-to-end.

The following figure summarizes fundamental supervisory guidelines, which should act as one of the core guiding principles for EWI selection and monitoring at a bank.

Applications of EWIs in the Context of Liquidity Risk Management Process

The EWI framework can be summarized as M.E.R.I.T. (Measures, Escalation, Reporting, Integrated systems, and Thresholds).

  1. Measures

    To obtain a forward-looking view of liquidity risk, a bank must employ metrics that examine the structure of the balance sheet in addition to metrics that (b) project cash flows and future liquidity positions, taking into account (c) off-balance sheet risks. These measures must span vulnerabilities across normal and stressed conditions over various time horizons.

    1. Forward-looking bias/view

      For prudent risk management, a firm requires these internal and external metrics. These measures ideally need to be leading (forward-looking) and sharp (sufficiently granular). A leading indicator provides information and signals possible stress before the occurrence of an actual event. On the other hand, sharp indicators are signals that do not go unnoticed within the mass of data. For example, detecting a drop in overall deposit balances is an acceptable EWI. However, detecting drops in deposit balances of more volatile segments, such as high-net-worth customers or rate-sensitive product balances, brings into focus that certain crucial classes of customers are leaving the bank.

      EWIs that are both forward-looking and sharp give management more time to take mitigating actions. Additionally, it helps to ensure that managers have a better understanding of risk drivers and trends than broad, lagging indicators may otherwise provide.

      Liquidity events can start either within a bank or may be influenced by external elements triggered by the environment in which the bank is set up. EWIs should be positioned to capture emerging internally-driven stress events before becoming public knowledge, for example, through monitoring of loan performance, planned significant accounting adjustments, and operational losses.

      Alternatively, a systemic crisis such as a sovereign default or banking system crisis may trigger liquidity dislocations in parts of the financial market system, disrupting the funding of any institutions that are exposed to those markets. The following figure shows EWI dimensions.

    2. Environments, Both Normal and Stressed

      EWIs provide signals for a potential future disaster. It is essential to track appropriate EWI metrics during a business-as-usual environment as any deterioration in these metrics will alert the bank’s leadership of weaknesses in the bank’s balance sheet or of the emergence of challenging circumstances in the markets that the bank operates within.

      Including stressed measures and limits in institutions’ EWI lists aids to gauge the adequacy of the firm’s liquidity buffer for a stressed environment. Finally, stress testing results may expose previously unidentified or emerging concentrations and risks that could threaten the viability of the institution.

    3. Spanning Various Time Horizon

      EWI coverage must reflect various time horizons to match the institution’s unique balance sheet needs, including the market and economic conditions under which it operates, the time horizons that match banking forecasts and business operations can be daily, weekly, or monthly. EWIs may even be monitored on an intraday basis, as warranted by business conditions or required by regulators.  

  2. Escalation

    Leading firms select and gauge EWIs to transmit meaningful signals to management about the need for corrective action in light of impending firm-specific distress.

    Once an EWI registers a change in status, a robust and well-established escalation process aids in ensuring that the management reviews the trends to understand the cause better, identify the potential impacts of evolving business dynamics, and take appropriate measures. The firm’s selection of EWIs and their calibration should be reviewed to reflect any changes to business mix and activities and the changing nature of the macroeconomic and market environments.

  3. Reporting

    The EWI dashboard should be reported daily to provide managers with adequate time to make adjustments in response to potential crises. Companies with substantial trading focus use intraday reporting because they are more exposed to external market conditions. Reporting should be broad enough to provide comprehensive coverage. Additionally, it should be specific enough to communicate vital information.

  4. Integrated Systems

    Integrated data and systems provide liquidity managers with the ability to ensure that reported metrics are accurate and in sync with each other. Automation and integration are crucial as EWI frameworks supplement traditional market-based metrics with a vast array of internal indicators.

  5. Thresholds

    Typically, firms employ the stoplight system to represent and communicate their performance against the thresholds of their EWIs. A green indicator implies that the measure is within the normal range. An amber measure should be investigated further while a red indicator should be an alarm of a significant concern and may warrant an immediate response. Furthermore, the threshold boundaries for which an EWI moves from green to amber should not be so broad that movements go undetected, and the metric continually indicates that the economic and internal environments are healthy.

Industry Practices

Firms, particularly banks, have increased the attention and resources for developing and maintaining EWI dashboards and their overarching governance. This can be massively attributed to demands from supervisory bodies in the form of matters requiring attention (MRAs). In some instances, the firm’s leadership self-initiatives should be given credit to enhance its liquidity management and solidify risk reporting.

Practice Question

You are a financial risk manager at Stanlab Bank. Your supervisor asks you to prepare a list of early warning indicators for liquidity problems for the bank. Which of the following is an inaccurate early warning indicator of a potential liquidity problem?

A. Rapid asset growth, primarily when funded with probable volatile liabilities.

B. Increase of weighted average maturity of liabilities.

C. Significant deterioration in the bank’s financial condition.

D. Counterparties requesting additional collateral or resisting entering into new transactions.

The correct answer is B.

It is the decrease of the weighted average maturity of liabilities that is an early warning indicator of a potential liquidity problem.

Options A, C, and D are EWIs as recommended by the Basel Committee on Banking Supervision (BCBS).

    Professor James' videos are excellent for understanding the underlying theories behind financial engineering / financial analysis. The AnalystPrep videos were better than any of the others that I searched through on YouTube for providing a clear explanation of some concepts, such as Portfolio theory, CAPM, and Arbitrage Pricing theory. Watching these cleared up many of the unclarities I had in my head. Highly recommended.
