WHY THE UNWINDING OF THE JAPANESE CARRY TRADE COULD TRIGGER A GLOBAL MARKET SHOCK

FOR NEARLY TWO DECADES, JAPAN HAS PLAYED A CRITICAL ROLE IN THE GLOBAL FINANCIAL SYSTEM. WITH INTEREST RATES CLOSE TO ZERO AND AN EXTREMELY ACCOMMODATIVE MONETARY POLICY, THE COUNTRY BECAME THE WORLD’S PRIMARY SOURCE OF CHEAP CAPITAL. IN PRACTICAL TERMS, JAPAN OPERATED AS A GLOBAL ATM, SUPPLYING LOW-COST MONEY TO FINANCE RISK ACROSS FINANCIAL MARKETS.

THIS MECHANISM IS KNOWN AS THE CARRY TRADE. INVESTORS BORROWED IN JAPANESE YEN AT NEAR ZERO COST AND DEPLOYED THAT CAPITAL INTO HIGHER-YIELDING ASSETS SUCH AS EQUITIES, CRYPTOCURRENCIES, EMERGING MARKET DEBT, AND REAL ESTATE. AS LONG AS JAPANESE RATES STAYED LOW AND THE YEN REMAINED WEAK, THE STRATEGY APPEARED STABLE, PROFITABLE, AND ALMOST RISK-FREE.

THE PROBLEM IS THAT THESE CYCLES NEVER LAST FOREVER. WHEN CONDITIONS SHIFT, THE UNWINDING OF A CARRY TRADE IS RARELY GRADUAL. IT IS OFTEN FAST, VIOLENT, AND DESTRUCTIVE. THAT IS EXACTLY THE RISK THAT IS NOW BEGINNING TO EMERGE.

THE KEY WARNING SIGNAL IS THE SPEED OF MOVEMENT IN LONG-TERM INTEREST RATES, ESPECIALLY THE 10-YEAR YIELD. A SLOW, ORDERLY INCREASE IN THE 10Y CAN BE ABSORBED BY MARKETS. BUT WHEN YIELDS MOVE TOO FAST, THEY FORCE A SUDDEN REPRICING OF RISK AND TRIGGER A RUSH TO UNWIND LEVERAGED POSITIONS.

THE MECHANICS ARE STRAIGHTFORWARD. A FUND BORROWED IN YEN AT LOW COST AND INVESTED IN U.S. EQUITIES OR CRYPTO ASSETS. IF LONG-TERM RATES RISE QUICKLY AND THE YEN STRENGTHENS, THE COST OF ROLLING THAT DEBT SPIKES. TO LIMIT LOSSES, THE INVESTOR IS FORCED TO SELL ASSETS, PUTTING IMMEDIATE DOWNWARD PRESSURE ON PRICES.

THIS PROCESS QUICKLY BECOMES SELF-REINFORCING. FALLING ASSET PRICES LEAD TO MARGIN CALLS. MARGIN CALLS FORCE ADDITIONAL LIQUIDATION. LIQUIDATION PUSHES PRICES EVEN LOWER. THIS IS HOW LIQUIDITY CYCLES END, NOT QUIETLY, BUT THROUGH SHARP, DISORDERLY MOVES ACROSS MULTIPLE MARKETS.

HISTORY PROVIDES CLEAR EXAMPLES. IN 2008, THE UNWINDING OF LEVERAGED POSITIONS FUNDED BY LOW-YIELDING CURRENCIES ACCELERATED THE GLOBAL FINANCIAL CRISIS. IN EARLY 2020, DURING THE PANDEMIC SHOCK, A SUDDEN SCRAMBLE FOR LIQUIDITY CAUSED ABRUPT MOVES IN LONG-TERM YIELDS, FORCING CENTRAL BANKS INTO MASSIVE EMERGENCY INTERVENTIONS.

IF THE 10-YEAR YIELD MOVES TOO FAST NOW, THE RISKS ARE SIMILAR. EQUITIES COULD FACE SHARP CORRECTIONS, CRYPTO MARKETS COULD ENTER A VIOLENT DELEVERAGING PHASE, AND REAL ESTATE, HIGHLY SENSITIVE TO INTEREST RATES, COULD EXPERIENCE A SUDDEN AND PAINFUL SLOWDOWN.

FOR INVESTORS, THIS IS A MOMENT THAT DEMANDS CLOSE ATTENTION. THIS IS NOT ABOUT PANIC, BUT ABOUT RECOGNIZING A CLASSIC FINANCIAL PATTERN. WHEN CHEAP MONEY BEGINS TO DISAPPEAR AND LONG-TERM RATES ACCELERATE, MARKETS ARE FORCED TO REPRICE RISK RAPIDLY.

JAPAN CEASING TO FUNCTION AS THE WORLD’S ATM IS NOT A LOCAL EVENT. IT REPRESENTS A POTENTIAL GLOBAL LIQUIDITY SHOCK. AND HISTORY SHOWS THAT WHEN THESE CYCLES END, THEY RARELY END SMOOTHLY.
