Factors Affecting Performance [Text Block]
HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
For the twelve months ended December 31, 2024, Class A shares of Templeton Global Bond Fund returned -11.95%. The Fund compares its performance to the FTSE World Government Bond Index, which returned -2.87% for the same period.  
PERFORMANCE HIGHLIGHTS
Top contributors to performance:
↑
Interest-rate strategies contributed to absolute performance due to select exposures to countries in which bond yields fell over 2024, including duration exposure in India.
↑
Among currencies, underweight exposure to the euro contributed to relative returns.
Top detractors from performance:
↓
Currency positions detracted from absolute results, as the U.S. dollar (USD) remained stronger than expected. Select positions in Asian and Latin American currencies (including the Japanese yen and Brazilian real) detracted from performance.
↓
Within interest-rate strategies, duration exposures in Brazil and the U.S. detracted from absolute performance.
↓
Currency positions detracted from relative performance. Overweight currency positions in select Asian and Latin American currencies (including the Japanese yen and Brazilian real) detracted from relative performance.
Use of derivatives and the impact on performance:
The Fund utilized foreign exchange forwards and written and purchased currency options to gain additional exposure to currencies. Given that the USD appreciated against most currencies in 2024, these derivatives detracted from performance. Interest rate swaps were used to manage duration exposure, which also detracted from performance.

PERFORMANCE HIGHLIGHTS
Top contributors to performance:
↑
Interest-rate strategies contributed to absolute performance due to select exposures in countries in which bond yields fell over 2024, including duration exposures to select countries in Africa and Asia (including Egypt and Ghana).
↑
Overall credit exposures contributed to absolute results, due to exposure to USD-denominated sub-investment-grade credits.
↑
Overall credit exposures contributed to relative results, due to overweight exposure to USD-denominated sub-investment-grade credits. Interest-rate strategies contributed to relative performance due to select overweight exposures in Africa and Asia (including Egypt and Ghana). Among currencies, underweight exposure to the euro contributed to relative results.
Top detractors from performance:
↓
Currency positions detracted from absolute results, as the U.S. dollar (USD) remained stronger than expected. Select positions in Asian, Latin American, European and Africa currencies (including the Japanese yen and Brazilian real) detracted from performance.
↓
Within interest-rate strategies, duration exposure in Brazil detracted from absolute performance.
↓
Currency positions detracted from relative results. Select overweight positions in Asian, Latin American, European and Africa currencies (including the Brazilian real and Japanese yen) detracted from performance. Underweight exposure to corporate bonds also detracted from relative performance, as did underweight duration exposure to China and overweight duration exposure to Brazil.
Use of derivatives and the impact on performance:
The Fund utilized foreign exchange forwards and written and purchased currency options to gain additional exposure to currencies. Given that the USD appreciated against most currencies in 2024, these derivatives detracted from performance. Interest rate swaps were used to manage duration exposure, which also detracted from performance.

Top contributors to performance:
↑
Interest-rate strategies contributed to absolute performance due to select exposures in countries in which bond yields fell over 2024, including duration exposures to select countries in Africa and Asia (including Egypt and Ghana).
↑
Overall credit exposures contributed to absolute results, due to exposure to USD-denominated sub-investment-grade credits.
↑
Overall credit exposures contributed to relative results, due to overweight exposure to USD-denominated sub-investment-grade credits. Interest-rate strategies contributed to relative performance due to select overweight exposures in Africa and Asia (including Egypt and Ghana). Among currencies, underweight exposure to the euro contributed to relative results.
Top detractors from performance:
↓
Currency positions detracted from absolute results, as the U.S. dollar (USD) remained stronger than expected. Select positions in Asian, Latin American, European and Africa currencies (including the Japanese yen and Brazilian real) detracted from performance.
↓
Within interest-rate strategies, duration exposure in Brazil detracted from absolute performance.
↓
Currency positions detracted from relative results. Select overweight positions in Asian, Latin American, European and Africa currencies (including the Brazilian real and Japanese yen) detracted from performance. Underweight exposure to corporate bonds also detracted from relative performance, as did underweight duration exposure to China and overweight duration exposure to Brazil.
Use of derivatives and the impact on performance:
The Fund utilized foreign exchange forwards and written and purchased currency options to gain additional exposure to currencies. Given that the USD appreciated against most currencies in 2024, these derivatives detracted from performance. Interest rate swaps were used to manage duration exposure, which also detracted from performance.

Within interest-rate strategies, underweight duration exposures to China and the euro area detracted from relative performance.
Use of derivatives and the impact on performance:
The Fund utilized foreign exchange forwards and written and purchased currency options to gain additional exposure to currencies. Given that the USD appreciated against most currencies in 2024, these derivatives detracted from performance.

PERFORMANCE HIGHLIGHTS
Top contributors to performance:
↑
Interest-rate strategies contributed to absolute performance due to select exposures to countries in which bond yields fell over 2024, including duration exposures in Egypt and India.
↑
Overall credit exposures contributed to absolute results, due to select exposures to sub-investment grade sovereign credits in Latin America.
↑
Overall credit exposures contributed to relative results, due to select overweighted exposures to sub-investment grade sovereign credits in Latin America. Among currencies, an underweighted position in the Mexican peso contributed to relative results. Within interest-rate strategies, overweighted duration exposures in Egypt and India also contributed.
Top detractors from performance:
↓
Currency positions detracted from absolute results, as the U.S. dollar (USD) remained stronger than expected, due to select currency exposures in Latin America and Asia (including the Brazilian real and Uruguayan peso). Within interest-rate strategies, duration exposure in Brazil detracted from absolute performance.
↓
Currency positions detracted from relative results, due to select overweighted currency exposures in Latin America and Asia (including the Uruguayan peso and Kazakhstani tenge).
↓
Interest-rate strategies detracted from relative results, due to underweighted duration exposures in South Africa and China and overweighted duration exposure in Brazil.
Use of derivatives and the impact on performance:
The Fund utilized foreign exchange forwards to gain additional exposure to currencies. Given that the USD appreciated against most currencies in 2024, these derivatives detracted from performance. Interest rate swaps were used to manage duration exposure, which also detracted from performance.
