Direct Answer
A broad idea of how plentiful U.S. dollar funding is for borrowers worldwide. There is no single standard series; common proxies include the Bank for International Settlements series on dollar credit to non-U.S. borrowers and funding-market measures such as cross-currency basis.
Global Dollar Liquidity: Formula, Meaning, Signals, Examples and How to Use It
How Is Global Dollar Liquidity Calculated?
A broad idea of how plentiful U.S. dollar funding is for borrowers worldwide. There is no single standard series; common proxies include the Bank for International Settlements series on dollar credit to non-U.S. borrowers and funding-market measures such as cross-currency basis.
Formula: No single formula. One common proxy: year-over-year growth of USD credit to non-bank borrowers outside the U.S. = (credit now / credit one year ago) - 1
Inputs:
- Outstanding USD-denominated credit to borrowers outside the U.S.
- Same series one year earlier
- Optional: cross-currency basis, Federal Reserve swap line usage
Worked example. Dollar credit to non-U.S. borrowers of 14.2 trillion against 13.5 trillion a year earlier (illustrative figures) is year-over-year growth of 5.2%. The inputs are illustrative numbers, not market data.
Reading it. Faster growth in dollar credit and a narrow cross-currency basis are commonly read as easy dollar liquidity; slowing credit and a widening basis point to scarcity, which tends to pressure non-U.S. borrowers and risk assets.
Limits. Because the concept is defined differently across sources, series are not interchangeable. BIS data are published with a lag and are quarterly, so they say little about day-to-day funding stress.
What is Global Dollar Liquidity?

How to use Global Dollar Liquidity
Faster growth in dollar credit and a narrow cross-currency basis are commonly read as easy dollar liquidity; slowing credit and a widening basis point to scarcity, which tends to pressure non-U.S. borrowers and risk assets. A reading alone is never a buy or sell signal; it needs context from price structure, volume, volatility and the broader market regime.
Strengths
- Focusing on USD credit to borrowers outside the US targets dollar debt owed by non-US borrowers, a funding channel domestic data do not cover.
- A year-over-year growth rate removes the level and shows the pace, so periods of strong and weak dollar credit expansion can be compared.
- Reproducible when the formula and data convention are fixed.
Weaknesses and limitations
- Cross-currency basis and swap line usage describe price and stress rather than quantity, so combining them with credit growth mixes different kinds of data.
- Credit growth is a net figure of borrowing and repayment, so a flat reading can hide offsetting flows across borrower types.
- Correlated indicators can create false confidence by repeating the same underlying information.

Frequently Asked Questions
Is Global Dollar Liquidity a buy or sell signal?
No. Faster growth in dollar credit and a narrow cross-currency basis are commonly read as easy dollar liquidity; slowing credit and a widening basis point to scarcity, which tends to pressure non-U.S. Because the concept is defined differently across sources, series are not interchangeable. A trade built on it still needs a trigger, an invalidation rule, a position size and realistic execution assumptions.
What is the best setting for Global Dollar Liquidity?
Global Dollar Liquidity is computed from outstanding USD-denominated credit to borrowers outside the U.S; same series one year earlier; optional: cross-currency basis, Federal Reserve swap line usage, so the choices that matter are the data convention and the window it is read over. Test those across instruments, regimes and out-of-sample periods instead of fitting one historical winner.
Can Global Dollar Liquidity be used by itself?
Because the concept is defined differently across sources, series are not interchangeable. BIS data are published with a lag and are quarterly, so they say little about day-to-day funding stress. For that reason it is read next to measures of direction, participation, valuation, liquidity and risk, not alone.
Does Global Dollar Liquidity work on every timeframe?
The calculation (No single formula. One common proxy: year-over-year growth of USD credit to non-bank borrowers outside the U.S. = (credit now / credit one year ago) - 1) can be run on any bar size, but behavior is not portable: a reading on a five-minute chart describes a very different market window from the same reading on a daily chart. Validate the exact timeframe before relying on it.
Why does Global Dollar Liquidity give false signals?
Cross-currency basis and swap line usage describe price and stress rather than quantity, so combining them with credit growth mixes different kinds of data. Credit growth is a net figure of borrowing and repayment, so a flat reading can hide offsetting flows across borrower types. Lag, noise and regime changes add to this, because market participants react to new information after the reading is calculated.
How should Global Dollar Liquidity be backtested?
Rebuild Global Dollar Liquidity from outstanding USD-denominated credit to borrowers outside the U.S using point-in-time data, write the rules before testing, include delisted securities where relevant, model realistic fills and costs, reserve a validation sample and compare with a simpler baseline.
