U.S. Treasury Increased Long-Term Bond Buyback Amounts

The U.S. Department of the Treasury increased the size of liquidity-supporting buyback operations for long-term nominal coupon securities. The maximum buyback amount, previously set at $2 billion per operation, was increased to at least $4 billion.

The change took effect on September 9 and will remain in place until November 4, 2026.

U.S. Bank Completed a Cross-Border Payment Using Its Own Stablecoin

U.S. Bank completed a live cross-border payment pilot using USBDC, its own U.S. dollar-pegged stablecoin. The transaction was carried out between the bank’s entities in North America and Europe over the Stellar blockchain.

The pilot tested the issuance and transfer of USBDC, as well as the stablecoin’s minting, redemption, freezing, and clawback functions. These processes were carried out together with the bank’s existing finance, risk, compliance, and operations systems. U.S. Bank also stated that it is evaluating different use cases, including cross-border treasury transactions, liquidity management, and collateral transfers.

Why is it important?

The pilot involved the use of a bank-issued stablecoin for a live cross-border transfer on a public blockchain. During the transaction, the stablecoin infrastructure was tested together with the bank’s existing risk, compliance, and operational systems.

Proposal for a 25% Tax on Crypto Gains Emerged in Germany

Germany’s Federal Ministry of Finance was reported to have prepared a draft proposal that would introduce a 25% tax on cryptocurrency trading gains starting in 2028.

According to the draft, the new system would apply to crypto assets acquired after January 1, 2027. Assets purchased before this date are expected to remain subject to the existing tax rules under transitional provisions.

Under Germany’s current system, gains from crypto assets held for more than 12 months may be tax-exempt under certain conditions. The draft proposal has not yet entered into force.

Why is it important?

The draft proposes a change to Germany’s current tax exemption system linked to holding crypto assets for more than 12 months. If approved, crypto gains covered by the proposal would be subject to a 25% tax starting in 2028.
