•  Japanese yen surged to a six-week high due to Tokyo's inflation rate exceeding expectations, leading to speculation about a potential interest rate hike by the Bank of Japan.
• The dollar has seen a slump against most major peers, but is still on track for a more than 2% gain for November, largely driven by Donald Trump's election victory.
• The yen's strength is also boosted by safe haven flows amid Trump's broad tariff warnings and growing bets that the BOJ will raise rates again on December Despite the yen's surge and Tokyo's core consumer price index rise, not everyone is convinced that a rate hike is imminent, with Mizuho Securities strategist Shoki Omori expecting the BOJ to keep policy settings steady next month.

The Japanese yen has recently made headlines, surging to a six-week high of 150 per dollar. This significant increase, as much as 1%, comes on the heels of an inflation rate in Tokyo that exceeded expectations. This development has led to increased speculation about a potential interest rate hike by the Bank of Japan (BOJ) in the near future.

On the other hand, the dollar has seen a slump against most major peers, with trading volumes thinned due to the U.S. Thanksgiving holiday. Sterling has reached its highest since November 20, while the euro is gradually recovering, edging back toward Wednesday's one-week high after a minor decline in the previous session.

Despite the dollar's recent slump, following its surge to a two-year high against a basket of key rivals a week ago, it is still on track for a more than 2% gain for November. This follows its more than 3% leap last month, largely driven by Donald Trump's resounding election victory on November 5.

Trump's Victory and Its Impact on the Dollar

The victory of Donald Trump has pumped up expectations of big fiscal spending, higher tariffs, and tighter borders, all seen by economists as inflationary. However, this week, the dollar index is on track for a 1.5% slide. The yen, in contrast, has made a notable comeback, set for gains of about 3%.

Beyond the dollar's weakness, exacerbated by sliding Treasury bond yields, Japan's currency has also been boosted by safe haven flows amid Trump's broad tariff warnings to Mexico, Canada, and China this week. Growing bets that the BOJ will raise rates again on December 19 have also contributed to the yen's strength. Traders currently lay about 60% odds for a quarter-point increase, and just over half of economists in a Reuters poll predicted the same.

Adding to the case for a hike, Tokyo's core consumer price index (CPI), which excludes volatile fresh food costs, rose 2.2% in November from a year earlier. This exceeded a median market forecast for a 2.1% gain and accelerated from a 1.8% increase in October.

Global Financial Developments

However, not everyone is convinced that a rate hike is imminent. Mizuho Securities strategist Shoki Omori expects the BOJ to keep policy settings steady next month. He argues that real service consumption, which carries significant weight in the Tokyo consumer price index, is gradually picking up but not enough for the BOJ to go bullish on a rate hike.

In other news, Asian stocks rose as the yen strengthened following Tokyo inflation data that exceeded estimates. Stocks in mainland China gained as food, beverage, and dining stocks advanced after officials held a meeting to boost consumption. Meanwhile, the European Central Bank cut its key interest rate to 3.25%, in its third quarter-percentage-point reduction of the year. The move had been fully priced by markets after policymakers flagged reduced inflation risks and a weakening growth outlook.

In the US, the Federal Reserve kept interest rates steady at a 23-year high for the fourth straight meeting and signaled that it may not start cutting rates until inflation sustainably moves towards a two per cent target. These developments in the global financial markets are reminiscent of similar events in the past. For instance, the yen's surge mirrors its performance in the late 1980s when it appreciated significantly against the dollar due to Japan's booming economy. Similarly, the European Central Bank's rate cut echoes its actions during the 2008 financial crisis when it slashed rates to stimulate the economy.

The recent surge in the yen and the potential for a BOJ rate hike next month are significant developments in the global financial markets. These events, along with the performance of other major currencies and stock markets, will continue to shape the global economic landscape in the coming months. It is crucial to keep an eye on these developments as they unfold, as they have far-reaching implications for investors and economies worldwide.
