Asia-focused banks face bond market risks ahead of Q3 earnings

While major regional banks continue to benefit from healthy deposit bases and solid earnings, rising long-term bond yields and broader macroeconomic headwinds are exposing vulnerabilities across their balance sheets, analysts said, Reuters reported.

The concerns follow a global bond market sell-off in early October, when the benchmark 10-year US Treasury yield touched a multi-year high of 5.34% before stabilising around 5.11%. A concurrent rise in Japanese government bond yields has added to the pressure on financial institutions across the region.

Higher yields can reduce the market value of banks' bond holdings, weigh on profitability and weaken capital ratios. These pressures could also constrain lenders' ability to raise fresh funds and prompt analysts to lower earnings-per-share forecasts, a closely watched measure among investors, Reuters reported, citing JPMorgan's co-head of APAC financials and head of ASEAN research, Harsh Wardhan Modi.

HSBC, Standard Chartered and DBS in focus

Major Asia-focused lenders are preparing to report quarterly results, with HSBC set to kick off the earnings season on Tuesday, followed by Standard Chartered on Wednesday. Singapore's DBS Group is scheduled to report its results next week.

Analysts expect HSBC to report a 33% increase in pretax profit for the July-September quarter. Standard Chartered is forecast to post broadly flat profit compared with the same period last year, while DBS is expected to report a 3.2% decline in net profit, Reuters reported.

The recent bond market turmoil has already weighed on bank shares. HSBC and Standard Chartered fell 3.8% and 9%, respectively, following the US Treasury market sell-off earlier this month.

In Southeast Asia, DBS shares declined 3.2%, while OCBC fell nearly 9% over the same period.

The decline in bond valuations could erode banks' book values and put pressure on key capital ratios, potentially affecting dividend payouts, Morningstar equity analyst Kathy Chan said, according to Reuters.

However, banks' ability to generate capital through their underlying earnings could help offset some of these pressures, she added.

Japanese lenders face rising bond losses

Japan's banking sector is particularly exposed to rising government bond yields, which are increasing unrealised losses on lenders' holdings of long-duration assets.

Moody's has warned that the pressure has already contributed to credit rating downgrades for some regional lenders, including Norinchukin Bank and Japan Post Bank.

Further increases in Japanese interest rates could intensify the strain on banks' balance sheets, Moody's Ratings associate managing director for financial institutions, Alka Anbarasu, said, according to Reuters.

The potential for additional rate increases remains a concern for lenders holding substantial portfolios of long-dated securities, as higher yields reduce the market value of existing bonds.

Inflation and currency volatility threaten Southeast Asian banks

Beyond bond market pressures, emerging market lenders in Southeast Asia are contending with domestic economic challenges that could affect asset quality and funding costs.

In the Philippines and Indonesia, persistent inflation and increased foreign exchange volatility are beginning to put pressure on banks' asset quality and wholesale funding structures, Moody's analysts said, according to Reuters.

Currency fluctuations can increase uncertainty for lenders with foreign currency exposures, while elevated inflation can strain borrowers' repayment capacity and increase credit risks.

These challenges could complicate banks' efforts to maintain profitability as they navigate an increasingly uncertain macroeconomic environment.

Wealth management growth faces near-term headwinds

Regional lenders are also preparing for a possible slowdown in wealth management momentum following a period of strong growth driven by capital inflows from Chinese investors.

Singaporean banks, along with HSBC and Standard Chartered, have benefited from the expansion of wealth management activity and the movement of funds into regional financial centres.

However, tighter offshore tax scrutiny in China could slow these inflows in the near term, potentially affecting third-quarter results, Moody's analyst Sally Yim said, according to Reuters.

Despite the near-term uncertainty, the longer-term growth outlook for wealth management remains intact, she added.

As the earnings season begins, investors will watch how effectively Asia-focused banks manage bond valuation losses, maintain capital buffers, and sustain lending and fee income amid inflationary pressures and volatile currency markets. The results are likely to offer further insight into regional lenders' resilience as global financial conditions remain uncertain.
