Portugal Updates Its Public Debt Framework After 19 Years
After nearly two decades without structural changes, Portugal has introduced a new framework governing the management of public debt and state treasury operations by the IGCP.
The IGCP (Agência de Gestão da Tesouraria e da Dívida Pública) is the Portuguese government agency responsible for issuing and managing the State’s debt, overseeing cash balances, and ensuring that Portugal can meet its financing needs under all market conditions. The updated rules replace guidelines dating back to 2007 and reflect a clear shift toward a more conservative and resilient approach to sovereign debt management. The revision acknowledges how the macroeconomic and financial environment has changed since the global financial crisis and Portugal’s own sovereign debt episode.
Currency risk management has also become more conservative. Gross foreign-currency exposure has been reduced, and net currency exposure after hedging is now capped at just 5%, down from previous limits. Importantly, treasury investments are no longer permitted to generate currency risk at all, further insulating public finances from exchange-rate volatility.
This change represents a structural upgrade in Portugal’s treasury management, aligning it more closely with prudential standards applied to regulated financial institutions. It directly addresses vulnerabilities exposed during past periods of market stress, when access to funding became constrained.
In addition, the framework allows for the potential issuance of GDP-linked debt, aligning Portugal with international best practices in sovereign debt management. While still optional, this instrument could improve risk-sharing between the State and investors by linking debt servicing more closely to economic performance, without expanding into equity- or commodity-linked structures.

This progress has been supported by nominal growth, fiscal discipline, and active liability management. Looking ahead, official projections continue to point toward further gradual reductions in the debt ratio, assuming stable growth and contained primary balances. The new IGCP framework reinforces this trajectory by reducing refinancing, currency, and liquidity risks, lowering the probability of adverse debt dynamics during periods of market volatility.
For the Portugal Golden Income Fund, these developments are constructive. The Fund’s exposure to Portuguese corporate bonds benefits indirectly from a stronger sovereign backdrop, as improved public debt management supports refinancing conditions, credit spreads, and overall confidence across domestic capital markets. The formalisation of tighter risk limits at the sovereign level also reduces tail risks that historically weighed on Portuguese credit during periods of stress.
More broadly, within the Fund’s bond portfolio, the updated framework reinforces the case for maintaining exposure to high-quality Portuguese issuers in an environment characterised by stable carry generation, controlled volatility, and improved macro-credit visibility.
For investors, this evolution should reinforce confidence in Portugal’s fiscal stewardship and reduce vulnerability to market shocks over time. More broadly, it signals that the scars of past crises have translated into lasting institutional reform. After 19 years, Portugal’s public debt management enters a new phase: one built not for benign conditions alone, but for durability across the full economic cycle.

Tighter Control of Refinancing and Currency Risk
A central pillar of the new framework is stricter control of refinancing risk, which refers to the danger of having too much debt maturing within a short period. Under the revised rules, no more than 15% of outstanding debt may mature within the next 12 months, and no more than 45% may mature over the following five years. As of the end of September, Portugal was already operating close to these thresholds, with 15.3% of public debt maturing within 12 months and 38.9% scheduled to mature over the next five years. In addition, the framework now requires that the average residual maturity of public debt remains above seven years; at the end of September, Portugal’s average maturity stood at 7.5 years, comfortably above the newly established floor.Currency risk management has also become more conservative. Gross foreign-currency exposure has been reduced, and net currency exposure after hedging is now capped at just 5%, down from previous limits. Importantly, treasury investments are no longer permitted to generate currency risk at all, further insulating public finances from exchange-rate volatility.
Formal Liquidity Buffers for the First Time
For the first time, the framework introduces explicit and measurable liquidity requirements. The IGCP must now maintain liquid assets sufficient to cover 100% of estimated gross funding needs over the following 30 days, as well as total liquidity equivalent to at least 8.5% of projected annual financing needs.This change represents a structural upgrade in Portugal’s treasury management, aligning it more closely with prudential standards applied to regulated financial institutions. It directly addresses vulnerabilities exposed during past periods of market stress, when access to funding became constrained.
More Flexibility in Treasury Management
While risk limits have tightened, the framework also allows greater flexibility in managing short-term cash balances. The IGCP is now authorised to invest in high-quality sovereign debt outside the euro area, including U.S., Japanese, British, and Swiss government bonds, enhancing diversification while preserving liquidity and capital protection.In addition, the framework allows for the potential issuance of GDP-linked debt, aligning Portugal with international best practices in sovereign debt management. While still optional, this instrument could improve risk-sharing between the State and investors by linking debt servicing more closely to economic performance, without expanding into equity- or commodity-linked structures.
Portugal’s Debt Position: Improving from a Stronger Base
These reforms come at a time when Portugal’s debt metrics have already improved substantially. The public debt-to-GDP ratio has declined sharply from post-crisis peaks above 130% to around the low-90% range, making Portugal one of the strongest improvers within the euro area over the past decade.Image: Portugal's Public Debt as % of GDP

Implications for the Portugal Golden Income Fund and Bond Portfolio
For fixed-income investors, a more resilient sovereign funding structure tends to translate into lower structural risk premia, improved spread stability, and more predictable credit conditions.For the Portugal Golden Income Fund, these developments are constructive. The Fund’s exposure to Portuguese corporate bonds benefits indirectly from a stronger sovereign backdrop, as improved public debt management supports refinancing conditions, credit spreads, and overall confidence across domestic capital markets. The formalisation of tighter risk limits at the sovereign level also reduces tail risks that historically weighed on Portuguese credit during periods of stress.
More broadly, within the Fund’s bond portfolio, the updated framework reinforces the case for maintaining exposure to high-quality Portuguese issuers in an environment characterised by stable carry generation, controlled volatility, and improved macro-credit visibility.
Conclusion
Taken together, these changes mark a clear shift in Portugal’s approach to sovereign debt management. The new framework prioritises resilience, predictability, and protection against adverse scenarios over short-term optimisation. By formalising limits on refinancing, currency, and liquidity risk, Portugal significantly strengthens the structural quality of its public debt profile.For investors, this evolution should reinforce confidence in Portugal’s fiscal stewardship and reduce vulnerability to market shocks over time. More broadly, it signals that the scars of past crises have translated into lasting institutional reform. After 19 years, Portugal’s public debt management enters a new phase: one built not for benign conditions alone, but for durability across the full economic cycle.
