Upbit HBAR deposits and withdrawals halted for network upgrade

Published: 2026-05-15 08:27:50 |

Upbit announced a temporary suspension of Upbit HBAR deposits and withdrawals to support a Hedera (HBAR) network upgrade. The halt starts at 2:00 p.m. UTC on May 20, 2025 and will remain until the upgrade is completed and network stability is verified. During the maintenance window, users cannot move HBAR in or out of Upbit, but HBAR trading pairs are expected to continue. Upbit said the pause is a standard security measure to preserve transaction integrity. The exchange did not give an exact resume time, and traders should complete any pending Upbit HBAR deposits and withdrawals before the cutoff to avoid delays. The article notes potential short-term liquidity impacts, which may widen spreads and affect execution for HBAR orders. For Hedera holders, this mainly affects transfers to external wallets or other exchanges, reducing arbitrage and cross-platform rebalancing opportunities during the pause. Traders are advised to monitor Upbit’s official maintenance updates and Hedera’s network status for real-time timing. Overall, this is a routine operational event tied to Hedera’s ongoing roadmap, but it can still trigger temporary volatility around liquidity changes.

Neutral

This is not a protocol change to Hedera’s economics; it is an exchange-side operational halt. That typically creates short-term frictions—reduced HBAR on/off-ramp liquidity on Upbit—so spreads and execution quality can worsen temporarily. Because HBAR spot trading pairs are expected to stay live, the effect is more likely to be confined to transfer/arb activity than to broader market fundamentals. Historically, similar exchange deposit/withdrawal pauses tend to cause localized volatility around the start/end window as market participants rebalance or hedge ahead of reduced liquidity. If the maintenance runs smoothly, the long-term impact is usually minimal and price action mean-reverts after transfers resume. However, an unexpectedly long delay can extend liquidity constraints and amplify short-term selling pressure or dampen bids, creating a more bearish impulse. Given the article’s emphasis on a routine upgrade and the lack of any indicated network instability, the base case is neutral: traders should mainly manage timing risk (withdrawals/deposits) and expect potential intraday liquidity/premium effects on HBAR on Upbit during the maintenance window.
