Bitcoin is on track for its best month in a year. $5 billion USDT growth fuels the rebound

Bitcoin BTC$77,728.95 held above $77,000 on Friday, consolidating after hitting its strongest level since early February earlier in the week.

The largest cryptocurrency is up about 13.6% in April, putting it on track for its best monthly performance in a year, according to CoinGlass data. The rebound follows a rough stretch, with crypto markets logging their longest losing streak since 2018, posting consecutive monthly declines from October through February.

The turnaround comes as the broader macro backdrop has improved. U.S. equities have staged a strong recovery, with the S&P 500 and Nasdaq climbing back to record highs after briefly slipping into correction territory earlier this year.

But there’s a crypto-specific driver behind the move, too.

The supply of Tether's USDT USDT$1.0002, the largest and most popular stablecoin, has surged to just under $150 billion, adding about $5 billion over the past two weeks after months of stagnation.

That matters because stablecoins — cryptocurrencies tied to fiat money like the U.S. dollar — act as liquidity in crypto markets, the capital traders use to buy digital assets in the blockchain economy. Analysts often interpret stablecoin growth as a cue for capital flowing to the crypto market, a healthy signal for asset prices.

Markets 'stopped caring' about Iran war

Still, the macro picture hasn't cleared yet. Geopolitical tensions in the Middle East and uncertainty around the Iran war persist, keeping oil prices at elevated levels.

But for now, markets seem to be looking past it, said Jasper de Maere, OTC trader at Wintermute.

"The equities and crypto markets seem to have stopped caring about intricate headlines on the conflict's direction," de Maere. "This shows a certain level of fatigue and potentially complacency."
