After the approval of the crypto assets mortgage loan, IDX submitted the gold and Bitcoin ETF documents.

Gate News bot reported that according to CoinGape, shortly after the Federal Housing Finance Agency (FHFA) approved cryptocurrency mortgages on Wednesday, the asset management company IDX applied for a gold and Bitcoin combined ETF. The fund is named "IDX Alternative Fiat Currency ETF" and aims to provide investors with investment opportunities in a variety of digital asset portfolios, focusing on Bitcoin and gold. Against the backdrop of uncertainty in global markets, both asset classes achieved strong returns in 2025, making them the best tools for hedging market fluctuations.

The IDX alternative fiat currency ETF aims to provide a mixed allocation of gold and digital assets, primarily focusing on gold and Bitcoin. This ETF employs a dynamic asset allocation strategy to achieve balanced allocation between the two assets based on risk indicators such as volatility and momentum. At the time of this announcement, there has been strong inflow into Bitcoin ETFs over the past two months, highlighting the increasing participation of institutional investors.

The fund does not directly invest in digital assets such as Bitcoin, Ethereum (ETH), Solana (SOL), or Ripple (XRP), but primarily invests in futures and other financial instruments that can directly or synthetically invest in these core assets. Therefore, IDX will rely on exchange-traded products (ETP), futures, options, swaps, and other derivatives that provide exposure to these assets.

As indicated in the documents of the U.S. Securities and Exchange Commission (SEC), the IDX alternative fiat currency ETF focuses on Bitcoin and gold, while limiting the allocation ratio of related assets such as Ethereum, silver, gold mining stocks, and blockchain infrastructure companies to within 40%. IDX collectively refers to these as "reference assets."

Under normal circumstances, the fund aims to achieve a 1.25 times leveraged exposure, ensuring that at least 80% of net assets are allocated to instruments linked to Bitcoin and gold. According to Michael Saylor's strategy report, the demand for Bitcoin-backed fixed income assets has also been increasing recently.

This week, the inflow of Bitcoin spot ETFs surged, recording an additional $500 million inflow on Wednesday. The ETF market has maintained strong momentum with net inflows for 12 consecutive days, bringing the total new funds to nearly $4 billion. Since its launch in January 2024, this category has attracted nearly $50 billion in total inflows.
