Dollar Hits Two-and-a-Half-Month Low, Gold Above $4,400, Bitcoin +8%: One Decision Moves All Three

Some trading days see three markets tell the same story. August 19, 2026 was one of them. The dollar index (DXY) fell about 0.9 percent to around 98.8, its lowest reading since May 29. Gold climbed a little more than 2 percent to about $4,480 an ounce, its highest since early June. And bitcoin briefly jumped 8 percent to $69,749, closing the European evening at $68,361 (CoinMarketCap, 9:45 p.m. CEST; dollar and gold data from Barchart and FXStreet, August 19, 2026).

A soft dollar, strong gold and a leaping bitcoin on the same day are not a coincidence. They are three reactions to one decision: the U.S. Treasury is doubling its buybacks of long-dated government bonds.

The Decision That Set It Off

On August 18 the U.S. Treasury announced that its liquidity buybacks at the long end will double from $2 billion to at least $4 billion per operation, effective from September 9 to November 4, 2026. The 30-year U.S. yield, which had touched 5.337 percent the previous day — the highest reading since 2007 — fell back to 5.189 percent on the news.

The chain behind it fits in one sentence: when Washington actively pushes down long-end yields, the dollar loses its rate advantage, and everything that is not the dollar becomes relatively more attractive. That is why three asset classes that rarely march in step moved together on August 19.

Three Markets, One Cause

The gold-and-bitcoin pair is worth a second look. The two are usually cast as rivals, digital versus physical store of value. On days like this they behave as siblings. Both are anti-dollar trades, and both benefit when the world's biggest economy signals that it would rather inflate its debt burden away than tighten its way out.

What This Means for the Coming Weeks

Three checkpoints will decide whether the day becomes a trend:

The Fed minutes and the data. The buyback announcement hit a market that was already watching the central bank. If yields stay down, the tailwind for gold and bitcoin holds; if they push back above the recent highs, August 19 will read as a flash in the pan.

The dollar index around 98. A sustained break of the DXY below the May low would confirm the new regime. A quick rebound would suggest the market is treating the buybacks as a technical measure, not a change of direction.

Whether Washington doubles down. The buybacks run through November 4 for now. If Treasury extends or enlarges them, liquidity maintenance turns into a program. That is precisely the scenario the loudest price calls are betting on, from Standard Chartered's $100,000 year-end target to Arthur Hayes' shouts for $110,000 to $200,000 per bitcoin. Both are wagers on the liquidity thesis, not certainties.

The full story of how the rally played out — including the SEC proposal, the White House summit and the short squeeze — is in our market recap for August 19. The mirror-image day has happened too: earlier this spring gold added $1.3 trillion in market value in a single day while bitcoin stalled, so the roles are interchangeable.

Gold or Bitcoin? A Sharper Answer to the Wrong Question

Anyone reaching for a choice between gold and bitcoin after a day like this is usually asking the wrong question. The two differ less in direction than in character. Gold moves in percent, bitcoin in multiples of that, in both directions. On August 19, gold rose 2 percent and bitcoin 8; in a drawdown the ratio flips the same way.

In practice, that means position size belongs to volatility, not to conviction. And playing both sides of the anti-dollar trade does not require two brokers. At the regulated broker XTB, stocks and ETFs plus CFDs on gold, indices and crypto trade from one account, long or short; new customers currently receive a free Nike share.

Frequently Asked Questions

Why is the dollar falling right now? The U.S. Treasury is doubling its long-end buybacks from September 9. That pushed long-term yields down, and with the rate advantage the dollar's bid faded: the DXY hit its lowest level since late May on August 19.

Why are gold and bitcoin rising at the same time? Both are yield-free anti-dollar assets. When the dollar and real yields fall together, the opportunity cost of holding either drops, and both become cheaper for buyers outside the dollar zone.

Is this already a dollar crisis? No. A decline to a two-and-a-half-month low is a sizable move, but not a crisis. The buybacks run to November 4 for now; whether they harden into a regime change will be settled by an extension and by yields.

What does it mean for my portfolio? That the "gold or bitcoin" question matters less than position size. Bitcoin moves several times as far as gold, in both directions. Holding both means holding two versions of the same bet against the dollar, not two independent assets.
