Global equities and government bonds gained, while the yen strengthened sharply, reflecting a renewed shift in positioning ahead of data that could influence expectations for the Federal Reserve's next policy decision. The yen has gained almost 2% over two sessions, while the US 10-year Treasury yield fell three basis points to 4.766%, according to Reuters. Markets were pricing roughly a 60% probability of a Federal Reserve rate increase this month.

The market response comes against a difficult backdrop. Investors have spent recent sessions weighing elevated energy prices, renewed military confrontation between the United States and Iran, persistent inflation risks and a global bond sell-off that has pushed borrowing costs higher.

The recovery therefore represents less a return to complacency than a tactical reassessment of risk. Falling bond yields have provided some relief for equity valuations, particularly after the recent increase in government borrowing costs intensified concerns over the sustainability of public finances.

The US labour market is now central to that calculation. Evidence of weakening employment conditions could alter expectations for monetary policy, while signs of persistent strength could reinforce the case for maintaining or increasing restrictive rates.

For investors, the tension is increasingly between inflation and growth. Higher oil prices threaten to reinforce price pressures at precisely the moment when financial markets are searching for evidence that economic activity may be losing momentum.

The yen's renewed strength also carries wider implications. Higher Japanese yields and changing expectations for the Bank of Japan are making domestic assets more attractive, potentially altering the direction of international capital flows.

Aldrenor assessment: The immediate market rally masks a more fragile global environment. Monetary policy, energy security and sovereign borrowing costs are increasingly interconnected, leaving September as a critical test of whether investors can sustain risk appetite without a meaningful improvement in the underlying macroeconomic picture.
