From Yen to Dollars: The Two Risks Shaking the Markets

Markets are once again showing signs of weakness, but this time it’s no coincidence. Behind the recent declines are two interconnected risk mechanisms revolving around yen and dollar dynamics, triggering a cascade of liquidations that affect all asset classes.

The Ghost of the Shutdown: U.S. Uncertainty

The first threat comes from Washington. The chances of the U.S. government entering a shutdown are around 78%, a figure reflecting the difficulty in reaching agreements on federal funding. With a critical deadline approaching, Democrats have indicated their intention to vote against the new funding package.

When the possibility of a shutdown materializes, something very specific happens in the markets: political uncertainty increases, risk appetite evaporates, and investors react precipitously, selling first and asking questions later. This behavior affects both traditional markets and the cryptocurrency ecosystem, where volatility is amplified.

The Yen Maneuver: When Currencies Revalue

The second factor is more subtle but potentially more destructive. Japan has been allowing its currency to remain weak for years, a policy that has facilitated a massive capital flow: investment funds borrow in cheap yen and convert it into dollars to invest in stocks and cryptocurrencies. This is the famous “yen carry trade.”

The danger begins when there are signals that the Federal Reserve might intervene in the currency market. Japan’s Prime Minister has already warned about measures against “abnormal” yen movements, and traders report that the New York Fed has contacted major banks, a typical step before formal intervention. If that happens, the scenario is clear: the U.S. would sell dollars and buy yen to strengthen the Japanese currency.

What then occurs is a chain reaction. As the yen appreciates, funds that bet with borrowed money in cheap yen are forced to close their positions to repay the loans. This means selling stocks and cryptocurrencies en masse, causing rapid declines and contagion across interconnected markets.

The Perfect Storm

As these two macroeconomic risks intensify, the trade conflict between Trump, Europe, and Canada adds additional pressure. And next week will bring even more volatility: consumer confidence data, Fed interest rate decisions, earnings reports from Microsoft, Meta, Tesla, and Apple, as well as PPI inflation figures. All these catalysts will converge in a scenario where yen-to-dollar and dollar-to-yen movements will continue to be the invisible force behind market movements.
