Bank of Japan sees highest lending growth since COVID as rate hikes reshape crypto carry trade

Japan’s banks just posted their strongest lending growth in over five years, and the Bank of Japan is responding exactly how you’d expect: by making borrowing more expensive. The 5.7% year-over-year jump in May 2026 marks the fastest credit expansion since March 2021, when pandemic-era emergency lending was still inflating the numbers.

The numbers behind Japan’s credit surge

Total outstanding loans hit JPY 670.8 trillion in May, building on a 5.4% increase recorded in April. The acceleration wasn’t evenly distributed across Japan’s banking system, though.

Major banks led the charge with an 8.7% year-over-year expansion in their loan books. Regional banks came in at a more modest 4.3% growth rate. Shinkin banks, Japan’s cooperative lenders that serve smaller businesses and local communities, managed just 1.7%.

The BoJ’s own April 2026 Financial System Report flagged two notable trends: a rise in real-estate-related lending and increased loans flowing to foreign investment funds.

The rate hike that barely registered

On June 16, the BoJ raised its benchmark interest rate by 25 basis points to 1%, the highest level since 1995. The decision passed in a decisive 7-1 vote, with some policymakers actually pushing for even faster tightening due to inflation pressures tied to energy prices.

The August 2024 rate hike famously contributed to a global equity selloff and sent Bitcoin tumbling as the yen carry trade unwound violently. This time, Bitcoin and the broader crypto market barely moved.

What the carry trade evolution means for crypto

With Japanese rates now at 1% and potentially heading higher, the spread between Japanese borrowing costs and returns available elsewhere is narrowing. The fact that crypto didn’t sell off on the June rate hike suggests the market has already adapted.

What investors should actually watch

The real-estate lending increase flagged in the BoJ’s Financial System Report deserves particular scrutiny. Japan’s property market has been on a tear, with foreign capital pouring in and domestic prices rising in major cities.

For crypto traders, the key variable isn’t Japan’s lending growth per se. It’s the velocity of future rate hikes. The BoJ’s hawkish minority, those pushing for faster tightening in the June vote, bears watching. If inflation data gives them ammunition, the consensus could shift quickly.
