Basel III, bank capital, and the illusion of guaranteed safety

Why Tier 1 gold, paper gold bans, and deposit guarantees are widely misunderstood, and what actually happens in a crisis.

Bottom line: Basel III improves bank resilience in ordinary stress. It does not guarantee safety in a severe systemic downturn as capital can be exhausted. Deposit guarantees rely on government backstops, not a vault of cash.

What Tier 1 and Tier 2 capital actually are

Under Basel III, “Tier 1” and “Tier 2” refer to a bank’s capital (its own loss‑absorbing funds), not to assets like gold or silver.

·       Tier 1 capital: the bank’s core equity buffer, consists of ordinary shareholders’ equity and retained earnings (plus certain perpetual instruments). It absorbs losses first.

·       Tier 2 capital: the secondary buffer, consists of subordinated instruments that absorb losses after Tier 1 is exhausted.

Assets are not Tier 1; they drive how much capital a bank must hold

Gold, silver, bonds, and loans are assets. Basel does not label assets Tier 1. Instead, Basel rules determine how much Tier 1 capital the bank must hold behind each asset based on risk and liquidity characteristics.

Why physical gold is treated favourably (and paper gold is not)

Allocated physical gold

Allocated gold means specific bars are held outright (no counterparty promise). Because counterparty risk is minimised, allocated gold can be treated very favourably for regulatory purposes in some jurisdictions, making it capital‑efficient.

Paper gold (ETFs, unallocated accounts, swaps, futures)

Paper gold exposures are claims and contracts, not ownership. They introduce counterparty, margin, and funding risks. Basel III does not “ban” paper gold; it penalises it via capital and stable‑funding maths, making large paper books balance‑sheet inefficient.

Myth: “Basel III forces banks to hold only physical gold.”

Reality: Basel III treats physical gold more favourably than other forms of paper gold because of counterparty risk. Banks often reduce paper exposure voluntarily because it is more expensive (capital‑intensive).

What happens when a bank gets into difficulty

There are two distinct problems: liquidity stress (can’t meet outflows today) and solvency stress (losses exceed capital).

Liquidity stress

The bank needs cash quickly. Regulators require banks to hold High Quality Liquid Assets (HQLA) for this purpose (cash and government bonds, not commodities). In stress, a bank may sell other assets, but haircuts widen, settlement slows, and “saleable” is not the same as “reliably liquid”.

Solvency stress (loss absorption waterfall)

Losses are absorbed in a strict order:

Losses occur  ↓Tier 1 capital (shareholders / retained earnings)  ↓AT1 / hybrids (if any)  ↓Tier 2 capital (subordinated instruments)  ↓Senior creditors  ↓Depositors (only after buffers are exhausted)

Bank guarantees: investor checklist to determine a bank's liquidity position

A depositor typically wants one thing in a severe downturn: confidence the bank can meet withdrawals without selling assets at fire‑sale prices. The quickest way to assess this is to separate capital (loss‑absorption) from liquidity (cash‑flow survival) and then look for the bank’s disclosed liquidity ratios and funding profile.

Step 1 — Do not confuse “equity” with “cash”

·       Equity / shareholder funds / retained profits are the bank’s loss‑absorbing buffer. This is not a pile of cash. It is the residual claim after liabilities.

·       Cash and cash equivalents is an asset line item, but for banks it can be misleading on its own because liquidity strength is driven by stress outflows and the quality of liquid assets.

Step 2 — Look for the bank’s liquidity metrics (more informative than raw cash)

·       LCR (Liquidity Coverage Ratio): designed to show whether the bank holds enough High Quality Liquid Assets (HQLA) to survive a short, severe stress period. Higher is generally better; persistent weakness is a red flag.

·       NSFR (Net Stable Funding Ratio): designed to show whether the bank’s assets are funded with sufficiently stable liabilities over a one‑year horizon. Low NSFR indicates greater refinancing risk.

These are usually disclosed in the annual report and/or Pillar 3 (APS 330) disclosures, and may also appear in investor presentations.

Step 3 — Check “liquid assets” quality: HQLA vs everything else

·       HQLA (cash and high‑quality sovereign securities) is what matters most in a run or funding freeze.

·       Other “liquid” items (corporate bonds, structured products, commodities) may be saleable in normal markets but can become illiquid or heavily discounted in stress.

Step 4 — Stress vulnerability indicators (what to look for when a bank does not have much liquidity)

·       Thin HQLA buffer or LCR close to the minimum, especially if it is trending down.

·       Funding dependence on short‑term wholesale markets (heavy reliance on short‑dated borrowing rather than stable deposits/longer‑term funding).

·       Rapid asset growth without commensurate funding growth (often shows up as rising wholesale funding or declining liquidity ratios).

·       High concentration exposures (e.g., a narrow loan book, concentrated sector or geography) which can magnify losses and funding stress simultaneously.

·       Large “trading” or derivative books that can create sudden margin calls and liquidity drains in volatile markets.

·       Large maturity mismatches (long‑dated assets funded by short‑dated liabilities), which is precisely what liquidity regulation is designed to constrain.

Practical depositor rule: If you cannot easily locate the bank’s LCR/NSFR and capital ratios in public disclosures, treat that as a transparency warning sign. For major Australian ADIs, these disclosures are typically accessible and clearly labelled.

Where an investor can look for a bank’s “real capital” and liquidity position

If you want to see the bank’s equity (shareholder funds and retained profits), capital ratios (CET1 / Tier 1 / Total), and liquidity metrics (LCR / NSFR), use the sources below.

·       Annual report / audited financial statements: look for the Equity section of the balance sheet (share capital, retained earnings, reserves) and the capital notes (CET1 / Tier 1 / Total capital ratios).

·       Pillar 3 (APS 330) disclosures: large ADIs publish detailed “Pillar 3” reports and Excel tables describing capital adequacy, risk‑weighted assets, leverage, and liquidity (as required by APRA’s public disclosure rules).

·       APRA statistics (MADIS / quarterly ADI statistics): APRA publishes entity‑level and industry data on capital and liquidity (including LCR and NSFR) for ADIs.

·       ASX announcements / investor presentations: banks disclose capital updates, ratio movements, and funding/liquidity commentary in results materials.

Important: “cash on hand” is not the same thing as “capital”. Capital is the bank’s loss‑absorbing equity buffer. Liquidity is the bank’s ability to meet cash outflows on time. Both matter — and they are disclosed in different places.

From credit risk to monetary risk: Why depositors still lose

Modern financial regulation has largely succeeded in one respect: large banks are far less likely to collapse suddenly due to private‑sector credit failures alone. Capital buffers are denser, liquidity is monitored continuously, and authorities intervene earlier than in past cycles.

But this success has come with a trade‑off. System stability is now preserved increasingly through monetary expansion rather than market discipline. Credit losses that once destroyed banks are absorbed by balance sheets, guarantees, and ultimately sovereign money creation.

This means that today’s dominant risk is not a classic credit implosion, but a monetary one:

·       Banks remain open and deposits are honoured.

·       Guarantees are met in nominal terms.

·       Purchasing power erodes through inflation and financial repression.

For depositors, this distinction matters. Safety increasingly means nominal safety, not preservation of real value. Balance sheets and capital ratios can reassure that a bank will survive — but they cannot guarantee what your money will buy once it does.

Final takeaway: Modern systems are designed to prevent bank failure and bank guarantees will be honoured, even if that means sacrificing the long‑term value of money. Stability is prioritised; wealth preservation is not.
