Abstract
Pada akhir November 2020, jumlah utang pemerintah meningkat secara signifikan yang tercatat sebesar Rp5.910 triliun dengan rasio terhadap Produk Domestik Bruto (PDB) mencapai 38,13%. Peningkatan rasio utang tersebut menjadi peringatan agar pemerintah Indonesia semakin bijaksana dalam mengelola pembiayaan utang. Oleh karena itu, pemerintah Indonesia senantiasa menerapkan pengelolaan utang secara bijak melalui diversifikasi komposisi utang valuta asing. Dalam kajian akademik, optimasi komposisi utang dapat diibaratkan dengan optimasi portofolio saham seperti menggunakan model Mean-Variance, akan tetapi model ini memiliki keterbatasan dalam menangkap risiko ekstrem. Sebagai solusi dari keterbatasan ini, digunakan model Conditional Value-at-Risk dan Worst-Case Conditional Value-at-Risk untuk mempertimbangkan risiko pada tingkat ketahanan yang lebih ekstrem. Dengan memanfaatkan data suku bunga dan nilai valuta asing dari DJPPR Kementerian Keuangan Republik Indonesia, data ini akan dihitung pada ketiga model dengan tingkat ukuran risiko yang berbeda dan nantinya akan dilakukan simulasi pada Matlab dengan memanfaatkan function yang sesuai. Sehingga dihasilkan komposisi paling optimal untuk strategi dengan batasan khusus, yaitu terpilihnya model Mean-CVaR dengan bobot tertinggi yaitu USD_5Y sebesar 50,50% dan bobot terendah yaitu EUR_10Y sebesar 0,00%, dengan ekspektasi perubahan nilai utang sebesar 0,04300 x 10^-3. Sedangkan, untuk strategi tanpa batasan khusus, ketiga model menghasilkan komposisi yang sama dengan bobot tertinggi yaitu USD_30Y sebesar 100% dan ekspektasi perubahan nilai utang sebesar 0,01700 10^-3, dengan model Mean-WCCVaR terpilih sebagai model paling optimal karena berhasil meminimumkan risiko pada CVaR sebesar 4,08031 x 10^-3. Dari hasil berikut diharapkan dapat memberikan kontribusi akademik serta rekomendasi kebijakan pemerintah terhadap diversifikasi komposisi utang valas.

At the end of November 2020, the amount of government debt increased significantly, recorded at Rp5,910 trillion with a ratio to Gross Domestic Product (GDP) reaching 38.13%. This increase in the debt ratio serves as a warning for the Indonesian government to be more prudent in managing debt financing. Therefore, the Indonesian government consistently implements prudent debt management through diversification of the foreign currency debt composition. In academic studies, debt composition optimization can be likened to stock portfolio optimization, such as using the Mean-Variance model; however, this model has limitations in capturing extreme risk. As a solution to this limitation, the Conditional Value-at-Risk and Worst-Case Conditional Value-at-Risk models are used to consider risk at a more extreme level of resilience. By utilizing interest rate and foreign exchange rate data from the DJPPR of the Ministry of Finance of the Republic of Indonesia, this data will be computed using the three models with different risk measurement levels, followed by simulation in Matlab using the appropriate functions. The results show that the most optimal composition for the strategy with special constraints is obtained from the Mean-CVaR model, with the highest weight being USD_5Y at 50.50% and the lowest weight being EUR_10Y at 0.00%, yielding an expected change in debt value of 0.04300 x 10^-3. Meanwhile, for the strategy without special constraints, all three models produce the same composition, with the highest weight being USD_30Y at 100% and an expected change in debt value of 0.01700 10^-3, with the Mean-WCCVaR model selected as the most optimal model as it successfully minimized the CVaR risk to 4.08031 x 10^-3. These results are expected to provide academic contributions as well as policy recommendations for the government regarding the diversification of foreign currency debt composition.
