Mehrling (2012) — Money View

Hierarchy, endogenous money, and the dollarization constraint

Monetary Hierarchy

What counts as money depends on where one stands in the hierarchy: each layer is money below, credit above.

Gold / US dollar
Ultimate international settlement asset; outside money no domestic authority can issue at will.
Currency / Central Bank money (HPM)
Domestic high-powered money: cash plus settlement balances at the central bank.
Bank deposits (M1, M2)
Bank liabilities payable at par in HPM; money for households, firms, and most payments.
Loans, bonds, securities
Promises to pay deposits or HPM in the future; most elastic in booms, least money-like in stress.

Dollarization fixes the apex constraint: Ecuador can use dollars as ultimate money, but cannot issue them.

Balance Sheet Mechanics — McLeay & Thomas (2014)

Banks don't lend savings — they create deposits. A new loan expands both sides of the balance sheet simultaneously.

New broad money is created without altering the stock of central bank money. The bank generates deposits at the moment of lending — no intermediation of existing resources.

Ecuador — Institutional Context

Seven features that shape dollar flows

01
Ecuador has a central bank which holds public and private sector deposits
Public and private liquidity structurally linked — BoP shocks affect both simultaneously
02
Private banks hold offshore external assets
Some transactions bypass official IR → Broad IR exceeds official IR
03
Oil exports state-exclusive
All oil export revenues belong to the government → public sector dominates HPM supply historically
05
Limited global financial integration
Foreign savings don't flow freely → credit growth constrained by domestic BoP dynamics
04
Public sector mandated to bank at BCE
All public foreign flows (debt, oil) must be brought onshore — BCE pools HPM for whole system
06
No developed domestic capital markets
Foreign portfolio inflows virtually non-existent → no cushion during external shocks
07

Private sector became net HPM supplier only in 2024 — historically the public sector dominated. Whether this reversal is permanent is the central open policy question.

Ecuador's Monetary System — Dual Currency & Primary Money Creation

HPM creates domestic money — not the other way around

Two Tiers of Money

HPM · Green $

Externally usable dollars. Scarce, finite, and governed by balance-of-payments flows.

International reserves, bank external assets, and cash.
The hard constraint behind domestic money expansion.
DM · Yellow $

Domestic money. Useful onshore and expandable through balance sheets.

Deposits and domestic payment balances.
Fragile when it outruns green-dollar inflows.

HPM Sources

Official international reserves
BCE channel for system-wide settlement liquidity.

Bank external assets
Offshore liquidity held by private banks.

IR are already inside the economy: each inflow creates a matching domestic liability; each outflow destroys deposits alongside reserves.

Risk Channel 1 - Central Bank Financing

Dollarization does not prevent monetization

The regime is not the binding constraint.

It is the legal framework that prevents a central bank from creating deposits in favor of the government.

If public spending is financed by central-bank balance-sheet expansion, domestic money rises without a matching green-dollar inflow.

Fiscal Monetization Mechanism

Credit expansion and deposit creation
1

CBE buys domestic debt

The central bank adds a government asset to its balance sheet.

2

Gov. deposit appears

A new public-sector deposit is created as a CBE liability.

3

Government spends

The public deposit moves into private bank reserves.

4

Private deposits rise

Banks credit households and firms with new deposits.

Net result: M2 expands without a BoP inflow. No new green dollar entered; yellow dollars multiplied.

Risk Channel 2 — Cross-Holdings

Illusory liquidity

Deposits rise, but HPM does not.

When Bank A buys a certificate issued by Bank B, reserves move between banks while the receiving bank creates a new deposit. A reciprocal operation repeats the effect in the opposite direction.

Why it matters

Cross-holdings can inflate M2 and liquidity indicators without new balance-of-payments inflows, obscuring the origin and quality of domestic money.

Example from Section 3.2.2

Bank

t = 0

Initial state: both banks hold excess reserves at the BCE.

t = 1

Bank A invests 200 in a Bank B certificate.

t = 2

Bank B reciprocates and invests 200 in Bank A.

Bank A
BCE reserves1,000
Local investments300
Deposits5,500
BCE reserves800 (-200)
Local investments500 (+200)
Deposits5,500

Net result: M2 rises by 400 while system-wide BCE reserves stay unchanged. These are yellow dollars created by accounting links, not new green dollars from the balance of payments. The operation is bounded by excess reserves and the reserve requirement ratio: max leverage = 1/r.

Risk Channel 3 — Fiscal-Monetary Link

Fiscal policy sets the money path

In a dollarized economy, the fiscal stance is also a liquidity stance.

Domestic public financing and spending move deposits, bank reserves, and pressure on HPM even when no new green dollars enter through the balance of payments.

The key question is not only whether fiscal policy is solvent. It is whether the resulting domestic claims remain credible against the available stock and flow of externally usable dollars.

From Fiscal Operation To Monetary Pressure

1

Fiscal stance

Deficits inject spending; consolidation withdraws purchasing power.

2

Domestic balance sheets

BCE, banks, and the Treasury reshuffle reserves and deposits.

3

Private deposits

M2 can rise or fall before the external constraint is visible.

4

HPM pressure

More domestic dollars eventually test the stock of green dollars.

Expansion

Domestic deficit finance can raise deposits and liquidity indicators without a matching BoP inflow.

M2 rises before the constraint bites.

Consolidation

Spending cuts or tax increases can contract deposits, reserves, and domestic payments capacity.

Liquidity falls even without de-dollarization.

Constraint

The sustainability test is whether domestic money growth is backed by durable HPM sources.

Green-dollar adequacy becomes the anchor.

Bottom line: under dollarization, fiscal and monetary dynamics cannot be separated. The public balance sheet helps determine both domestic liquidity and external fragility.

Diagnostic Questions

Who backs domestic money?

After the three risk channels, the issue is not only whether M2 expands. The diagnostic task is to identify which HPM source backs domestic claims, how stable that source is, and who manages access to green dollars.

Sustainability

Who supplies HPM when public flows recede?

The public sector has been a key provider of HPM through oil revenues and external debt. A fiscal transition can reduce that impulse and tighten domestic liquidity.

?Are private-sector inflows durable enough to replace public HPM supply?
!Liability-creating inflows can expand obligations without improving net foreign assets.
Public flows may no longer be the engine.

Institutional Anchor

What role should the BCE play as HPM pooler?

The BCE centralizes access to international settlement money, giving banks system-wide access to HPM rather than forcing each bank to self-insure in isolation.

Pooling supports equal access to green dollars across the banking system.
!Any substitute arrangement must avoid becoming a new money-creating balance sheet.
Pooling HPM is a systemic function.

Reserve Adequacy

Are we measuring the right reserve constraint?

Official IR alone misses a large part of usable HPM. In dollarization, adequacy depends on broad reserves and the flow dynamics that replenish or drain them.

1Broad IR captures official reserves, bank external assets, liquidity funds, and cash.
2Stable official reserves can hide offsetting inflows and outflows.
Adequacy is dynamic, not static.

Conclusions

Five key takeaways

01

BoP and domestic monetary system are codependent.

Primary money creation through external transactions fundamentally shapes the capacity for domestic credit expansion and, by extension, economic growth.

02

Dollarization does not prevent monetization — legislation does.

Ecuador 2009–2021 proved that a fully dollarized central bank can finance fiscal deficits. The regime itself offers no automatic protection.

03

Cross-holdings and domestic-debt spending inflate M2 without HPM backing.

Distorting indicators, generating illusory liquidity, and amplifying systemic fragility.

04

Private-sector HPM generation becomes a monetary imperative.

As public flows from oil and external debt decline under fiscal consolidation, the transition must be purposefully managed.

05

Reserve adequacy must be measured with Broad IR and dynamic flows.

Official IR alone understates HPM by ~48% in Ecuador. Static adequacy metrics miss the system's self-regulating logic.
