CROSS-ASSETDollar up, gold and bitcoin down
Friday followed a textbook pattern: real rates rising, a stronger dollar, and two havens falling at the same time.
DOLLAR (DXY)
99.68
+0.53% on Friday
BITCOIN
$77,372
-3.6% on the day
GOLD
~$4,600
flat on the week
THE PATTERN
+0.53%
the dollar (DXY) regained strength
As real rates rise, the dollar pulls in capital, and gold and bitcoin, which pay no interest, lose appeal at the same time. Both fell in the same session.
DATA
THE NUMBER99.68
99.68
▲ +0.53% · the dollar (DXY) regains strength
When the dollar rises, gold and bitcoin, which pay no interest, lose their appeal at the same time.
A stronger dollar and rising real rates push down anything that pays no coupon.
- COUPON
- — The periodic interest an asset pays. Neither gold nor bitcoin pays one.
- DOLLAR
- — The world's reserve currency. Its strength moves almost everything else.
QUOTE
PERSPECTIVEThe cost of paying no interest
“When safe money pays more, anything without a coupon, like gold or bitcoin, dims at the same time.”
Gold and bitcoin pay nothing. Their rival is safe money, and this week safe money pays more.
- OPPORTUNITY COST
- — What you give up by choosing one asset instead of another.
- SAFE MONEY
- — Low-risk assets, like Treasury bills, that pay interest.
PATH
AUGUSTThe dollar regained strength in August
An illustrative path of the dollar's climb in August. The 99.68 close is the real figure.
The dollar index (DXY) climbed through the month and closed near 99.7 on Friday.
- DXY
- — The dollar index against the euro, yen, pound and other currencies.
- CURRENCY
- — A country's money. The dollar is the global benchmark.
THE MECHANISM
4 STEPSWhy gold and bitcoin fall together
REAL RATES RISE
The interest left after subtracting inflation climbs. It's the dollar's biggest magnet.
THE DOLLAR STRENGTHENS
With real rates high, the dollar pulls in capital. The DXY closed at 99.68 (+0.53%).
GOLD FALLS
Gold pays no interest. If safe money pays more, its opportunity cost rises. It ended the week flat near $4,600.
BITCOIN FALLS
Bitcoin pays no coupon either. On Friday it dropped 3.6% to about $77,400, sold alongside gold.
It's a chain: real rates rise, the dollar rises, and anything without a coupon suffers.
- MAGNET
- — Here, the factor that pulls capital toward an asset or currency.
- CAPITAL
- — The money investors shift from one asset to another.
THE DAY
WHO MOVEDThe dollar-gold-bitcoin triangle
A rough split of Friday's move. Bitcoin, far more volatile, took the biggest share.
Of Friday's move, almost all of it belonged to bitcoin. Gold barely flinched.
- VOLATILITY
- — How much an asset's price swings. Bitcoin is among the highest.
- FLAT
- — When an asset barely changes price over the session.
WATCHLIST
5 KEY NAMESFive assets that tell the story
| UUP | 28 | ▲ +0.5% | Tracks the dollar. Rises when the DXY rises. |
| GLD | 424 | → -0.1% | Gold. Pays no interest: it suffers when safe money pays more. |
| IBIT | 44 | ▼ -3.6% | Spot bitcoin. Sold alongside gold on rising real rates. |
| TLT | 88 | ▼ -0.4% | Long US bonds. Their price falls when yields rise. |
