Central banks turn to gold as fiat currencies show signs of decline and loss of trust

Governments have long operated under the assumption that they can print unlimited amounts of fiat currency and enforce its acceptance. However, history reveals a recurring pattern: sovereigns exceed their credit limits, dismiss warning signs, and eventually face currency collapse. Today, developed economies’ fiat currencies appear to be in a phase of decline witnessed in real time, with the global reserve system gradually shifting away from pure fiat currency dominance toward a hybrid regime where gold increasingly takes centre stage.

Data from the International Monetary Fund’s Currency Composition of Official Foreign Exchange Reserves (COFER) highlights this historic shift. While the US dollar remains dominant, controlling close to 57% of reported official reserves, its share has steadily declined towards the high 50s percentile. Meanwhile, gold has surpassed both the US dollar and the euro as the principal asset held by central banks for the first time in four decades. This move away from fiat currencies reflects a fundamental erosion of confidence in the fiscal sustainability and monetary credibility of developed nations.

This loss of trust can be attributed to several factors. Developed economies have dramatically increased their indebtedness, with global public debt reaching an unprecedented $102 trillion, well beyond pre-pandemic levels and nearing past peaks seen during aggressive monetary expansion phases. Fiscal imprudence, exemplified by the United States under “Bidenomics,” has driven record deficits and spending surges exceeding $2 trillion during periods of economic recovery, accelerating concerns about sustainability.

Public debt issuance fundamentally represents currency issuance, yet sovereign debt no longer serves as a reliable reserve asset. Central banks have reported mounting losses due to inflation and solvency risks embedded in their substantial asset purchases, and inflation itself acts as a de facto gradual default, eroding the value of government obligations. The monetary, fiscal, and inflationary limits, benchmarks that when exceeded cause confidence to falter, have now been breached by multiple advanced economies.

The economic limit marks a stage where growing debt fails to produce additional growth, evidenced by GDP inflation from government spending amidst stagnating productivity and shrinking real wages. Fiscal limits arise as interest costs and entitlement spending crowd out investment, even under low interest rates and financial repression. Inflationary limits are crossed as persistent monetary financing undermines trust in the purchasing power of fiat money, pushing inflation beyond wage growth and triggering affordability crises.

Recognising these realities, central banks have responded with unprecedented gold purchases. Official net gold buying exceeded 1,100 tonnes in 2022 and remained above 1,000 tonnes in 2023 and into 2024, more than twice the pre-2020 average. Estimates suggest unofficial acquisitions may be significantly higher. According to recent surveys by the World Gold Council, over three-quarters of central banks plan to increase their gold reserves over the next five years, while nearly three-quarters expect to reduce their dollar-denominated holdings. This is set against a backdrop of record gold prices, which touched $3,500 per ounce in April 2025, up 95% from early 2022.

Leading financial institutions have revised their gold price forecasts upwards in response to strong demand. Goldman Sachs recently increased its 2025 year-end forecast to $3,100 per ounce, anticipating further price gains driven by central bank purchases and greater exchange-traded fund (ETF) holdings amid declining interest rates. More bullishly, ANZ Group raised its forecast to $3,800 per ounce by the end of 2025, with potential peaks near $4,000 by mid-2026, citing global uncertainty, weakening US dollar, dovish monetary policies, and geopolitical tensions.

A significant factor in this gold buying surge is the search for an asset free from default risk and central bank control, attributes gold uniquely provides in an era of fiscal strain and currency debasement. Central banks such as the People’s Bank of China, the National Bank of Poland, and the Reserve Bank of India, among others, have been consistently increasing their gold reserves. The PBoC notably recorded its longest ever streak of monthly gold additions, approaching 4.6% of total reserves by early 2024. Other nations including Kazakhstan, Singapore, Oman, and Kyrgyzstan have followed suit.

This shift signals a broader change toward a hybrid global reserve system, where fiat currencies coexist with higher allocations to gold and a growing interest in decentralised cryptocurrencies. While the US dollar remains the dominant global currency, accounting for 89% of transactions and 57% of reserves, it is increasingly regarded as part of a “declining empire” of fiat money suffering from eroding credibility.

The reaction from some central banks reveals anxiety about maintaining currency relevance. The European Central Bank plans to enforce greater euro usage via a digital currency, reflecting both desperation and regulatory control ambitions. The US government, meanwhile, promotes stablecoins backed by Treasury bonds to stimulate dollar demand, though this only partially addresses the root issues. Without substantial fiscal reforms, namely spending cuts and growth-focused policies, the risk of deteriorating confidence in the dollar remains high.

Paradoxically, few developed economies are committed to meaningful spending reductions despite towering debt-to-GDP ratios exceeding 100% and ongoing primary deficits. This political resistance suggests that many fiat currency issuers are trapped beyond their economic, fiscal, and inflationary boundaries, which may perpetuate instability.

The current trends mark a historic monetary transformation with profound long-term implications. Global central banks’ growing preference for gold over sovereign debt signals a fundamental distrust in paper promises. This sets the stage for a new monetary order where sound money and fiscal discipline lead to relative winners. Conversely, those clinging to unsustainable fiat regimes risk economic marginalisation and loss of global influence.

In summary, while an immediate collapse of the US dollar is not inevitable, the gradual erosion of confidence in fiat currencies across developed nations is reshaping the international financial landscape. Gold’s resurgence as a central bank reserve asset underscores the search for monetary stability amid geopolitical, fiscal, and inflationary uncertainty. This evolution towards a diversified reserve structure represents a critical shift in how nations manage their currencies and economic sovereignty in the 21st century.
